This page provides the release notes for the Agora Video SDK for Android.

Overview

The Video SDK supports the following scenarios:

  • Voice/Video Communication
  • Live Voice/Video Broadcast

For the key features included in each scenario, see Voice Overview, Video Overview, Audio Broadcast Overview and Video Broadcast Overview.

Known Issues and Limitations

Privacy changes

If your app targets Android 9, you should keep the following behavior changes in mind. These updates to device serial and DNS information enhance user privacy.

Build serial number deprecation

In Android 9, Build.SERIAL is always set to "UNKNOWN" to protect users' privacy.
If your app needs to access a device's hardware serial number, you should instead request the READ_PHONE_STATE permission, then call getSerial().

DNS privacy

Apps targeting Android 9 should honor the private DNS APIs. In particular, apps should ensure that, if the system resolver is doing DNS-over-TLS, any built-in DNS client either uses encrypted DNS to the same hostname as the system, or is disabled in favor of the system resolver.

For more information about privacy changes, see Android Privacy Changes.

v2.9.1

v2.9.1 is released on Sep 19, 2019.

New features

1. Detecting local voice activity

This release adds the report_vad(bool) parameter to the enableAudioVolumeIndication method to enable local voice activity detection. Once it is enabled, you can check the AudioVolumeInfo struct of the onAudioVolumeIndication callback for the voice activity status of the local user.

2. Choosing front and rear cameras

Users can select the front or rear camera before joining a channel. This release adds the cameraDirection member variable to the CameraCapturerConfiguration class to accomplish this. Choose the front or rear camera by selecting CAMERA_FRONT (1) or CAMERA_REAR (0) respectively.

3. Supporting RGBA raw video data

This release supports RGBA raw video data. Use the C++ method getVideoFormatPreference to set the format of the raw video data format.

You can also rotate or mirror the RGBA raw data using the C++ methods getRotationApplied or getMirrorApplied methods respectively.

4. Removing the event handler

This release adds the removeHandler method to remove specified IRtcEngineEventHandler objects when you want to stop listening for specific events.

Improvements

1. Improving the watermark function in Live Broadcasts

This release adds a new addVideoWatermark method with the following settings:

  • The visiblePreview member sets whether the watermark is visible in the local preview.
  • The positionInLandscapeMode/positionInPortraitMode member sets the watermark position when the encoding video is in landscape/portrait mode.

This release optimizes the watermark function, reducing the CPU usage by 5% to 20%.

The original addVideoWatermark method is deprecated.

2. Supporting more audio sample rates for recording

To enable more audio sample rate options for recording, this release adds a new startAudioRecording method with a sampleRate parameter. In the new method, you can set the sample rate as 16, 32, 44.1 or 48 kHz. The original method supports only a fixed sample rate of 32 kHz and is deprecated.

3. Adding error codes

This release adds the following error codes in the ErrorCode class:

  • ERR_ALREADY_IN_USE(19)
  • ERR_WATERMARK_PATH(125)
  • ERR_INVALID_USER_ACCOUNT(134)
  • ERR_AUDIO_BT_SCO_FAILED(1030)
  • ERR_ADM_NO_RECORDING_DEVICE(1359)
  • ERR_VCM_UNKNOWN_ERROR(1600)
  • ERR_VCM_ENCODER_INIT_ERROR(1601)
  • ERR_VCM_ENCODER_ENCODE_ERROR(1602)
  • ERR_VCM_ENCODER_SET_ERROR(1603)

For detailed descriptions for each error, see Error Codes.

Issues fixed

Audio

  • A user makes a call after connecting to a Bluetooth device. After the call ends, the user watches YouTube and cannot hear any sound.
  • The audio route is different from the settings in the setEnableSpeakerphone method when Bluetooth is connected in the Communication profile.
  • Exceptions occur in the audio route when a user is in the channel.
  • The app crashes when using external audio sources in the push mode.
  • Audio freezes.
  • After turning off the Bluetooth headset, the audio route becomes the earpiece instead of the loudspeaker.
  • Echos occur when a user is in the channel.
  • Occasional noise occurs in the Live Broadcast profile.

Miscellaneous

  • The OpenSSL version is outdated.

API Changes

Added

Deprecated

  • startAudioRecording
  • addVideoWatermark

v2.9.0

v2.9.0 is released on Aug 16, 2019.

Compatibility changes

1. RTMP streaming

In this release, we deleted the following methods:

  • configPublisher
  • setVideoCompositingLayout
  • clearVideoCompositingLayout

If your app implements RTMP streaming with the methods above, ensure that you upgrade the SDK to the latest version and use the following methods for the same function:

For how to implement the new methods, see Push Streams to the CDN.

2. Reporting the state of the remote video

This release extends the onRemoteVideoStateChanged callback with more states of the remote video: STOPPED(0), STARTING(1), DECODING(2), FROZEN(3), and FAILED(4). It adds a reason parameter to the callback to indicate why the remote video state changes. The original onRemoteVideoStateChanged callback is deleted. If you upgrade your Native SDK to the latest version, ensure that you re-implement the onRemoteVideoStateChanged callback.

The new callback reports most of the remote video states, and therefore deprecates the following callbacks. You can still use them, but we do not recommend doing so.

The triggering timing of the new callback is different from the old one. The new onRemoteVideoStateChanged callback is triggered only when the remote video state has changed.

3. Disabling/enabling the local audio

To improve the audio quality in the Communication profile, this release sets the system volume to the media volume after you call the enableLocalAudio(true) method. Calling enableLocalAudio(false) switches the system volume back to the in-call volume.

New features

1. Faster switching to another channel

This release adds the switchChannel method to enable the audience in a Live Broadcast channel to quickly switch to another channel. With this method, you can achieve a much faster switch than with the leaveChannel and joinChannel methods. After the audience successfully switches to another channel by calling the switchChannel method, the SDK triggers the onLeaveChannel and onJoinChannelSuccess callbacks to indicate that the audience has left the original channel and joined a new one.

2. Channel media stream relay

This release adds the following methods to relay the media streams of a host from a source channel to a destination channel. This feature applies to scenarios such as online singing contests, where hosts of different Live Broadcast channels interact with each other.

During the media stream relay, the SDK reports the states and events of the relay with the onChannelMediaRelayStateChanged and onChannelMediaRelayEvent callbacks.

For more information on the implementation, API call sequence, sample code, and considerations, see Co-host across Channels.

3. Reporting the local and remote audio state

This release adds the onLocalAudioStateChanged and onRemoteAudioStateChanged callbacks to report the local and remote audio states. With these callbacks, the SDK reports the following states for the local and remote audio:

  • The local audio: STOPPED(0), RECORDING(1), ENCODING(2), or FAILED(3). When the state is FAILED(3), see the error parameter for troubleshooting.
  • The remote audio: STOPPED(0), STARTING(1), DECODING(2), FROZEN(3), or FAILED(4). See the reason parameter for why the remote audio state changes.

4. Reporting the local audio statistics

This release adds the onLocalAudioStats callback to report the statistics of the local audio during a call, including the number of channels, the sending sample rate, and the average sending bitrate of the local audio.

5. Pulling the remote audio data

To improve the experience in audio playback, this release adds the following methods to pull the remote audio data. After getting the audio data, you can process it and play it with the audio effects that you want.

The difference between the onPlaybackFrame callback and the pullPlaybackAudioFrame method is as follows:

  • onPlaybackFrame: The SDK sends the audio data to the app once every 10 ms. Any delay in processing the audio frames may result in an audio delay.
  • pullPlaybackAudioFrame: The app pulls the remote audio data. After setting the audio data parameters, the SDK adjusts the frame buffer and avoids problems caused by jitter in external audio playback.

Improvements

1. Reporting more statistics of the in-call quality

This release adds the following statistics in the RtcStats, LocalVideoStats, and RemoteVideoStats classes:

  • RtcStats: The total number of the sent audio bytes, sent video bytes, received audio bytes, and received video bytes during a session.
  • LocalVideoStats: The encoding bitrate, the width and height of the encoding frame, the number of frames, and the codec type of the local video.
  • RemoteVideoStats: The packet loss rate of the remote video.

2. Improving the live broadcast video quality

This release minimizes the video freeze rate under poor network conditions, improves the video sharpness, and optimizes the video smoothness when the packet loss rate is high.

3. Other Improvements

  • Reduces the earpiece delay.
  • Improves the audio quality when the audio scenario is set to Game Streaming.
  • Improves the audio quality after the user disables the microphone in the Communication profile.

Issues fixed

Audio

  • When interoperating with a Web app, voice distortion occurs after the native app enables the remote sound position indication.
  • The audience cannot hear the host after the host sets the in-ear monitoring volume to 0.
  • Failure to play the audio file by calling the startAudioMixing method.
  • The audio route cannot be set to Bluetooth on some devices.
  • Crashes occur when using the raw audio data.
  • The audio route does not conform to the default settings after the device disconnects from Bluetooth.

Video

  • Occasional crashes occur when using the external video source.
  • The audience sees a black screen for the host's view.

Miscellaneous

  • Occasionally mixed streams in CDN streaming.
  • Occasional crashes occur after joining the channel on some devices.

API Changes

To improve the user experience, we made the following changes in v2.9.0:

Added

Deprecated

  • onMicrophoneEnabled. Use LOCAL_AUDIO_STREAM_STATE_CHANGED(0) or LOCAL_AUDIO_STREAM_STATE_RECORDING(1) in the onLocalAudioStateChanged callback instead.

  • onRemoteAudioTransportStats. Use the onRemoteAudioStats callback instead.

  • onRemoteVideoTransportStats. Use the onRemoteVideoStats callback instead.

  • onUserEnableVideo. Use the onRemoteVideoStateChanged callback with the following parameters instead:

    • REMOTE_VIDEO_STATE_STOPPED(0) and REMOTE_VIDEO_STATE_REASON_REMOTE_MUTED(5).
    • REMOTE_VIDEO_STATE_DECODING(2) and REMOTE_VIDEO_STATE_REASON_REMOTE_UNMUTED(6).
  • onUserEnableLocalVideo. Use the onRemoteVideoStateChanged callback with the following parameters instead:

    • REMOTE_VIDEO_STATE_STOPPED(0) and REMOTE_VIDEO_STATE_REASON_REMOTE_MUTED(5).
    • REMOTE_VIDEO_STATE_DECODING(2) and REMOTE_VIDEO_STATE_REASON_REMOTE_UNMUTED(6).
  • onFirstRemoteVideoDecoded. Use REMOTE_VIDEO_STATE_STARTING(1) or REMOTE_VIDEO_STATE_DECODING(2) in the onRemoteVideoStateChanged callback instead.

Deleted

  • configPublisher
  • setVideoCompositingLayout
  • clearVideoCompositingLayout
  • onRemoteVideoStateChanged

v2.8.2

v2.8.2 is released on Aug 1, 2019.

This release fixed the interoperating problem with the Agora Web SDK.

v2.8.1

v2.8.1 is released on Jul. 20, 2019.

New features

  • Support for the x86-64 architecture.
  • Support for Android Q.

v2.8.0

v2.8.0 is released on Jul. 8, 2019.

New features

1. Supporting string usernames

Many apps use string usernames. This release adds the following methods to enable apps to join an Agora channel directly with string usernames as user accounts:

For other methods, Agora uses the integer uid parameter. The Agora Engine maintains a mapping table that contains the user ID and string user account, and you can get the corresponding user account or ID by calling the getUserInfoByUid or getUserInfoByUserAccount method.

To ensure smooth communication, use the same parameter type to identify all users within a channel, that is, all users should use either the integer user ID or the string user account to join a channel. For details, see Use String User Accounts.

Note:

  • Do not mix parameter types within the same channel. The following Agora SDKs support string user accounts:

    • The Native SDK: v2.8.0 and later.
    • The Web SDK: v2.5.0 and later.

    If you use SDKs that do not support string user accounts, only integer user IDs can be used in the channel.

  • If you change your usernames into string user accounts, ensure that all app clients are upgraded to the latest version.

  • If you use string user accounts, ensure that the token generation script on your server is updated to the latest version. If you join the channel with a user account, ensure that you use the same user account or its corresponding integer user ID to generate a token. Call the getUserInfoByUserAccount method to get the user ID that corresponds to the user account.

2. Adding remote audio and video statistics

To monitor the audio and video transmission quality during a call or live broadcast, this release adds the totalFrozenTime and frozenRate members in the RemoteAudioStats and RemoteVideoStats classes, to report the audio and video freeze time and freeze rate of the remote user.

This release also adds the numChannels, receivedSampleRate, and receivedBitrate members in the RemoteAudioStats class.

Improvements

This release adds a CONNECTION_CHANGED_KEEP_ALIVE_TIMEOUT(14) member to the reason parameter of the onConnectionStateChanged callback. This member indicates a connection state change caused by the timeout of the connection keep-alive between the SDK and Agora's edge server.

Issues Fixed

Audio

  • Occasional audio freezes.

Video

  • When the user resumes receiving the remote video streams, the video stream switches to a low stream (low-resolution and low-bitrate video stream), and takes a long time to switch to a high stream.

Miscellaneous

  • When the log file path specified in the setLogFile method does not exist, no log file is generated and the default log file is incomplete.

API Changes

To improve your experience, we made the following changes to the APIs:

Added

Deprecated

v2.4.1

v2.4.1 is released on Jun 12, 2019.

Compatibility changes

Ensure that you read the following SDK behavior changes if you migrate from an earlier SDK version.

1. Publishing streams to the CDN

To improve the usability of the CDN streaming service, v2.4.1 defines the following parameter limits:

Class / Interface Parameter Limit
LiveTranscoding
  • videoFrameRate: Frame rate (fps) of the CDN live output video stream. The value range is [0, 30], and the default value is 15. Agora adjusts all values over 30 to 30.
  • videoBitrate: Bitrate (Kbps) of the CDN live output video stream. The default value is 400. Set this parameter according to the Video Bitrate Table. If you set a bitrate beyond the proper range, the SDK automatically adapts it to a value within the range.
  • videoCodecProfile: The video codec profile. Set it as BASELINE, MAIN, or HIGH (default). If you set this parameter to other values, Agora adjusts it to the default value of HIGH.
  • width and height: Pixel of the video. The minimum value of width x height is 16 x 16.
  • AgoraImage url: The maximum length of this parameter is 1024 bytes.
    addPublishStreamUrl url: The maximum length of this parameter is 1024 bytes.
    removePublishStreamUrl url: The maximum length of this parameter is 1024 bytes.

    This release also adds the audioCodecProfile parameter in the LiveTranscoding class to set the audio codec profile type. The default type is LC-AAC, which means the low-complexity audio codec profile.

    v2.4.1 also adds five error codes to the error parameter in the onStreamPublished method for quick troubleshooting.

    2. Renaming the receivedFrameRate parameter in the RemoteVideoStats class

    v2.4.1 renames the receivedFrameRate parameter to rendererOutputFrameRate in the RemoteVideoStats class to more accurately describe the statistics of the remote video stream.

    New features

    1. Adding media metadata

    In live broadcast scenarios, the host can send shopping links, digital coupons, and online quizzes to the audience for more diversified live broadcast interactions. v2.4.1 adds the registerMediaMetadataObserver interface and the IMediaMetadataObserver class, allowing the host to add metadata to the output video and to send media attached information.

    2. State of the local video

    v2.4.1 adds the onLocalVideoStateChanged callback to indicate the local video state. In this callback, the SDK returns the STOPPED,CAPTURING, ENCODING, or FAILED state. When the state is FAILED, you can use the error code for troubleshooting. This callback indicates whether or not the interruption is caused by capturing or encoding. This release deprecates the onCameraReady and onVideoStopped callbacks.

    3. State of the RTMP streaming

    v2.4.1 adds the onRtmpStreamingStateChanged callback to indicate the state of the RTMP streaming and help you troubleshoot issues when exceptions occur. In this callback, the SDK returns the IDLE, CONNECTING, RUNNING, RECOVERING, or FAILURE state. When the state is FAILURE, you can use the error code for troubleshooting. You can still use the onStreamPublished and onStreamUnpublished callbacks, but we do not recommend using them.

    4. More reasons for a network connection state change

    In the onConnectionStateChanged callback, v2.4.1 adds error codes to the reason parameter to help you troubleshoot issues when exceptions occur. The SDK returns the onConnectionStateChanged callback whenever the connection state changes. This release also deprecates WARN_LOOK_UP_CHANNEL_REJECTED(105), ERR_TOKEN_EXPIRED(109), and ERR_INVALID_TOKEN(110).

    5. State of the local network type

    v2.4.1 adds the onNetworkTypeChanged callback to indicate the local network type. In this callback, the SDK returns the UNKNOWN, DISCONNECTED, LAN, WIFI, 2G, 3G, or 4G type. When the network connection is interrupted, this callback indicates whether or not the interruption is caused by a network type change or poor network conditions.

    6. Getting the audio mixing volume

    v2.4.1 adds the getAudioMixingPlayoutVolume and getAudioMixingPublishVolume methods, which respectively gets the audio mixing volume for local playback and remote playback, to help you troubleshoot audio volume related issues.

    7. Reporting when the first remote audio frame is received and decoded

    To get the more accurate time of the first audio frame from a specified remote user, v2.4.1 adds the onFirstRemoteAudioDecoded callback to report to the app that the SDK decodes first remote audio. This callback is triggered in either of the following scenarios:

    • The remote user joins the channel and sends the audio stream.
    • The remote user stops sending the audio stream and re-sends it after 15 seconds.

    The difference between the onFirstRemoteAudioDecoded and onFirstRemoteAudioFrame callbacks is that the onFirstRemoteAudioFrame callback occurs when the SDK receives the first audio packet. It occurs before the onFirstRemoteAudioDecoded callback.

    Improvements

    1. Playing multiple online audio effect files simultaneously

    v2.4.1 adds the support for playing multiple online audio effect files simultaneously by allowing you to call the playEffect method multiple times with the URLs of the online audio effect files.

    2. Reporting more statistics

    3. Image enhancement

    v2.4.1 assigns default values to various parameters in the BeautyOptions class to improve the image enhancement experience. This release also optimizes the image enhancement algorithm. Test results from Agora Lab suggest that the updated algorithm leads to lower GPU and CPU consumption. The power consumption is optimized by over 30%.

    4. Miscellaneous

    • Improved the sound quality of the GAME_STREAMING audio scenario.
    • Reduced the audio and video latency.
    • Reduced the SDK package size by 0.5 M.
    • Improved the accuracy of the network quality after users change the video bitrate.
    • Enabled the audio quality notification callback by default, that is, enabled the onRemoteAudioStats callback without calling the enableAudioVolumeIndication method.
    • Improved the stability of video services.
    • Improved the stability of CDN streaming services.

    Issues fixed

    Audio

    • The audio stream is played through the loudspeaker even after the user plugs in the earphone.
    • The user cannot hear the audio mixing file through Bluetooth in the single-broadcaster scenario.
    • Exceptions occur when playing the audio mixing file in the Live Broadcast profile.

    Video

    • In the Live Broadcast profile, the view of the broadcaster is a black screen.

    Miscellaneous

    • Users still receive the onNetworkQuality callback after leaving the channel.
    • Occasional crashes.
    • The app quits after calling joinChannel.

    API changes

    To improve your experience, we made the following changes to the APIs:

    Unified the C++ interface for all platforms

    v2.4.1 unifies the behavior of the C++ interfaces across different platforms so that you can apply the same code logic on different platforms. v2.4.1 implements the methods of the RtcEngineParameters class in the IRtcEngine class. Refer to Agora C++ API Reference for All Platforms home page for the applicable platforms and considerations of each interface.

    Added

    Deprecated

    • enableAudioQualityIndication
    • onCameraReady. Use LOCAL_VIDEO_STREAM_STATE_CAPTURING(1) in the onLocalVideoStateChanged callback instead.
    • onVideoStopped. Use in LOCAL_VIDEO_STREAM_STATE_STOPPED(0) the onLocalVideoStateChanged callback instead.
    • The WARN_LOOKUP_CHANNEL_REJECTED(105) warning code. Use CONNECTION_CHANGED_REJECTED_BY_SERVER(10) in the onConnectionStateChanged callback instead.
    • The ERR_TOKEN_EXPIRED(109) error code. Use CONNECTION_CHANGED_TOKEN_EXPIRED(9) in the onConnectionStateChanged callback instead.
    • The ERR_INVALID_TOKEN(110) error code. Use CONNECTION_CHANGED_INVALID_TOKEN(8) in the onConnectionStateChanged callback instead.
    • The ERR_START_CAMERA(1003) error code. Use LOCAL_VIDEO_STREAM_ERROR_CAPTURE_FAILURE(4) in the onLocalVideoStateChanged callback instead.

    v2.4.0

    v2.4.0 is released on April 1, 2019.

    New Features

    1. Image enhancement

    In scenarios such as the video chat, interactive broadcast, and online education, basic beautification is a popular feature. v2.4.0 adds the setBeautyEffectOptions method, allowing you to adjust the contrast, brightness, smoothness and red saturation of an image. For more information, see Image Enhancement.

    2. Voice changer and voice reverberation

    Adding voice changer and reverberation effects in an audio chat room brings much more fun. v2.4.0 adds the setLocalVoiceChanger and setLocalVoiceReverbPreset methods, allowing you to change your voice or reverberation by choosing from the preset options. See Adjust the pitch and tone.

    3. Tracking the sound position of a remote user

    v2.4.0 adds the enableSoundPositionIndication and setRemoteVoicePosition methods. Call the enableSoundPositionIndication method before joining a channel to enable stereo panning for the remote users, and then you can call the setRemoteVoicePosition method to track the position of a remote user.

    4. Pre-call last-mile network probe test

    Conducting a last-mile probe test before joining the channel helps the local user to evaluate or predict the uplink network conditions. v2.4.0 adds the startLastmileProbeTest, stopLastmileProbeTest, and onLastmileProbeResult APIs, allowing you to get the uplink and downlink last-mile network statistics, including the bandwidth, packet loss, jitter, and round-trip time (RTT).

    5. Setting the priority of a remote user's stream

    v2.4.0 adds the setRemoteUserPriority method for setting the priority of a remote user's media stream. You can use this method with the setRemoteSubscribeFallbackOption method. If the fallback function is enabled for a remote stream, the SDK ensures the high-priority user gets the best possible stream quality.

    6. State of an audio mixing file

    v2.4.0 adds the onAudioMixingStateChanged callback to report any change of the audio-mixing file playback state (playback succeeds or fails) and the corresponding reason. This release also adds the warning code 701, which is triggered if the local audio-mixing file does not exist, or if the SDK does not support the file format or cannot access the music file URL when playing the audio-mixing file.

    7. Setting the log file size

    The SDK has two log files, each with a default size of 512 KB. In case some customers require more than the default size, v2.4.0 adds the setLogFileSize method for setting the log file size (KB).

    Improvements

    1. Accuracy of call quality statistics

    • v2.4.0 adds the intervalInSeconds parameter to the startEchoTest method, allowing you to set the interval between when you speak and when the recording plays back.
    • v2.4.0 adds three parameters to the LocalVideoStats class: targetBitrate for setting the target bitrate of the current encoder, targetFrameRate for setting the target frame rate, and qualityAdaptIndication for reporting the quality of the local video since last count.

    2. Video encoder preferences

    v2.4.0 provides the following options for setting video encoder preferences:

    • Setting preferences under limited bandwidth. v2.4.0 adds two parameters to the VideoEncoderConfiguration class: minFrameRate and degradationPrefer. You can use these parameters together to set the minimum video encoder frame rate and the video encoding degradation preference under limited bandwidth. For more information, see Set the Video Profile.

    • Setting the camera capture preference. v2.4.0 adds the setCameraCapturerConfiguration method, allowing you to set the camera capture preference. You can choose system performance over video quality or vice versa as needed. For more information, see the API Reference.

    3. Core quality improvements

    • Reduces the audio delay.
    • Improves the video quality and stability.
    • Shortens the time to render the first remote video frame.
    • Reduces the time delay when playing through the earpiece and minimizes the echo.

    Issues Fixed

    Audio

    • Calling the enableLocalAudio method disconnects all connected Bluetooth devices.
    • The SDK does not support audio mixing URLs with Chinese characters.
    • Volume levels of the high-pitch sound are lowered.
    • Sounds are occasionally played fast.
    • The app cannot adjust the volume on some devices.

    Video

    • If you skip the renderMode setting, the video stretches due to a mismatch with the display.
    • Video freezes on some lower-end devices.
    • It takes too long to render the first received video frame.

    Miscellaneous

    • The user drop-offline time between Android and iOS is not unified.
    • The SEI information does not synchronize with the media stream when publishing transcoded streams to the CDN.

    API Changes

    To improve your experience, we made the following changes to the APIs:

    Added

    Deprecated

    • startEchoTest
    • setVideoQualityParameters

    Miscellaneous

    v2.4.0 changes the type of the frameRate parameter in the VideoEncoderConfiguration class from enum to int.

    v2.3.3

    v2.3.3 is released on January 24, 2019.

    Issues Fixed

    • Occasional inaccurate statistics returned in the onNetworkQuality callback.
    • Occasional crashes on Huawei P9.

    v2.3.2

    v2.3.2 is released on January 16, 2019.

    Compatibility changes

    Besides the new features and improvements mentioned below, it is worth noting that v2.3.2:

    • Improves the SDK's ability to counter packet loss under unreliable network conditions.
    • Improves the communication smoothness.
    • Reduces video freezes in the Live Broadcast profile.

    Before upgrading your SDK, ensure that the version is:

    • Native SDK v1.11 or later.
    • Web SDK v2.1 or later.

    New Features

    1. Automatic exposure at a point of interest

    v2.3.2 adds the following methods and callback to support camera exposure and improve the captured video quality:

    You can send the touch point coordinates in the view to the SDK for automatic exposure.

    2. Video quality in a live broadcast

    v2.3.2 adds the minBitrate parameter (minimum encoding bitrate) in the setVideoEncoderConfiguration method. The SDK automatically adjusts the encoding bitrate to adapt to the network conditions. Using a value greater than the default value forces the video encoder to output high-quality images but may cause more packet loss and hence sacrifice the smoothness of the video transmission. Agora does not recommend changing this value unless you have special requirements for image quality.

    3. Independent audio mixing volume adjustments for local playback and remote publishing

    v2.3.2 adds the adjustAudioMixingPlayoutVolume and adjustAudioMixingPublishVolume methods to complement the adjustAudioMixingVolume method, allowing you to independently adjust the audio mixing volume for local playback and remote publishing.

    This release also changes the behavior of the adjustPlaybackSignalVolume method to control only the voice volume. Therefore, to mute the local audio playback, call both the adjustPlaybackSignalVolume(0) and adjustAudioMixingVolume(0) methods.

    See Adjust the Volume for the scenarios and corresponding APIs.

    Improvements

    1. Improves the accuracy of the call quality statistics

    v2.3.2 deprecates the onAudioQuality callback and replaces it with the onRemoteAudioStats callback to improve the accuracy of the call quality statistics. The onRemoteAudioStats callback returns parameters such as the audio frame loss rate, end-to-end audio delay, and jitter buffer delay at the receiver, which are more closely linked to the real user experience. In addition, v2.3.2 optimizes the algorithm of the onNetworkQuality callback for the uplink and downlink network qualities.

    • onRemoteAudioStats: Reports the statistics of the remote audio stream from each user/host. This callback replaces the onAudioQuality callback.
    • onNetworkQuality: Reports the last mile network quality of each user in the channel.

    We plan to improve the following callback in subsequent versions:

    • onLastmileQuality: Reports the last mile network quality of the local user before the user joins a channel.

    For the list of API methods related to the call quality statistics and on how and when to use them, see Report In-call Statistics.

    2. New network connection policy

    v2.3.2 adds the following API method and callback to get the current network connection state and the reason for a connection state change:

    v2.3.2 deprecates the onConnectionInterrupted and onConnectionBanned callbacks.

    In the new API method, the network connection states are "disconnected", "connecting", "connected", "reconnecting", and "failed". The SDK triggers the onConnectionStateChanged callback when the network connection state changes. The SDK also triggers the onConnectionInterrupted and onConnectionBanned callbacks under certain circumstances, but we do not recommend using them.

    3. Improves the call rating system

    v2.3.2 changes the rating parameter in the rate method to "1 to 5" to encourage more feedback from end-users on the quality of a call or live broadcast. You can use this feedback for future product improvement. We strongly recommend integrating this method in your app.

    4. Other improvements

    • Minimizes packet loss under unreliable network conditions in the Live Broadcast profile.
    • Accelerates the video quality recovery under network congestion.

    API Changes

    To improve your experience, we made the following changes to the APIs:

    Added:

    Deprecated

    v2.3.1

    v2.3.1 is released on October 12, 2018.

    New features

    Disables/Re-enables the Local Audio Function

    When a user joins a channel, the audio function is enabled by default.
    To receive audio streams without sending any audio stream after joining a channel, this version adds the enableLocalAudio method is to disable or re-enable the local audio function.
    Once the local audio function is disabled or re-enabled, the SDK returns the onMicrophoneEnabled callback, and the local audio capturing stops.
    This method does not affect receiving or playing the remote audio streams.

    The difference between this method and the muteLocalAudioStream method is that the enableLocalAudio method does not capture or send any audio stream, while the muteLocalAudioStream method captures but does not send audio streams.

    Improvements

    • Improves the SDK's adaptiveness to the Android video encoder.

    Issues Fixed

    • Occasional crashes when switching between front and rear cameras.
    • Occasionally, failing to render the video on some Android devices.
    • Occasional image freezes on some Android devices.
    • Occasionally on some Android devices, a user hears a popping sound if the user leaves the channel at the same time another user is speaking.
    • Communication profile: If a user disables the video and re-enables it during a one-to-one call, it takes a long time for the other user to see the image.
    • Live-broadcast profile: Delay at the client due to incorrect statistics.
    • Live-broadcast profile: Occasional crashes on some Android devices after a user repeats the process of switching roles between BROADCASTER and AUDIENCE.
    • The timestamp in the captured raw video frames does not refresh with the frame.

    v2.3.0

    v2.3.0 is released on August 31, 2018.

    Compatibility changes

    • To support video rotation and enable better quality for the custom video source, this version deprecates the setVideoProfile method and uses the setVideoEncoderConfiguration method instead to set the video encoding configurations. You can still use the setVideoProfile method, but Agora recommends using the setVideoEncoderConfiguration method to set the video profile because:

      • During a live broadcast, users can set the video orientation mode as adaptive, under which the SDK can transfer rotated video frames without cropping them, thus avoiding the “big headshot” or blurry images at the player.
      • In scenarios involving external video sources, the SDK adjusts the width and height of the output video frames based on the inputting video frames, avoiding unnecessary cropping and thereby rendering more image frames at the player.
    • From v2.3.0, the LiveTranscoding class is moved from the io.agora.live package to the io.agora.rtc.live package.

    • Fixed a typo in the constants.java API in v2.3.0.

      • Before:
      public static final int SOFEWARE_ENCODER = 1;
      • After:
      public static final int SOFTWARE_ENCODER = 1;
    • The security keys are improved and updated in v2.1.0. If you are using an Agora SDK version below v2.1.0 and wish to migrate to the latest version, see Token Migration Guide.

    New Features

    1. Fallback options for a live broadcast under unreliable network conditions

    The audio and video quality of a live broadcast deteriorate under unreliable network conditions. To improve the efficiency of a live broadcast, the setLocalPublishFallbackOption and setRemoteSubscribeFallbackOption methods are added. These interfaces allow the SDK to automatically disable the video stream when the network conditions cannot support both audio and video, and enable the video when the network conditions improve. The SDK triggers the onLocalPublishFallbackToAudioOnly or onRemoteSubscribeFallbackToAudioOnly callback when the stream falls back to audio-only or when the stream switches back to the video.

    2. Notifies the user that the token expires in 30 seconds

    The SDK returns the onTokenPrivilegeWillExpire callback 30 seconds before a token expires to notify the app to renew it. When this callback is received, you need to generate a new token on your server and call the renewToken method to pass the newly-generated token to the SDK.

    3. Returns user-specific upstream and downstream statistics, including the bitrate, frame rate, packet loss rate, and time delay

    The onRemoteAudioTransportStats and onRemoteVideoTransportStats callbacks are added to provide user-specific upstream and downstream statistics, including the bitrate, frame rate, and packet loss rate. During a call or a live broadcast, the SDK triggers these callbacks once every two seconds after the user receives audio/video packets from a remote user. The callbacks include the user ID, audio bitrate at the receiver, packet loss rate, and time delay (ms).

    4. Sets the video encoder configurations

    To support scenarios with video rotation and enable better quality for the custom video source, this version deprecates the setVideoProfile method and uses the setVideoEncoderConfiguration method instead to set the video encoding configurations. You can still use the setVideoProfile method, but Agora recommends using the setVideoEncoderConfiguration method to set the video profile because:

    • During a live broadcast, users can set the video orientation mode as adaptive, under which the SDK can transfer rotated video frames without cropping them, thus avoiding the “big headshot” or blurry images at the player.

    • In scenarios involving external video sources, the SDK adjusts the width and height of the output video frames based on the inputting video frames, avoiding unnecessary cropping and thereby rendering more image frames at the player.

    The VideoEncoderConfiguration class provides a set of configurable video parameters, including the dimension, frame rate, bitrate, and orientation. For more information on the API, see Set the Video Encoder Configuration.

    5. Adds support for background image settings in setLiveTranscoding

    The backgroundImage parameter is added to the setLiveTranscoding method allowing you to set the background image in the combined video of a live broadcast.

    Improvements

    • Improves the quality for one-on-one voice/video scenarios with optimized latency and smoothness, especially for areas like Southeast Asia, South America, Africa, and the Middle East.
    • Improves the audio encoder efficiency in a live broadcast to reduce user traffic while ensuring the call quality.
    • Improves the audio quality during a call or a live broadcast using the deep-learning algorithm.

    Issues Fixed

    • The users on the Web client cannot see the video sent from the Native client due to codec bugs.
    • Excessive increase in memory usage when multiple delegated hosts broadcast in the channel.
    • Occasional crashes on some Android devices.

    New Features

    1. Play the audio effect in the channel

    Adds a publish parameter in the playEffect method for the remote user in the channel to hear the audio effect played locally.

    If your SDK is upgraded to v2.2 from a previous version, pay attention to the functional changes of this API.

    2. Deploy the proxy at the server

    We provide a proxy package for enterprise users with corporate firewalls to deploy before accessing our services.

    3. Get the remote video state

    Adds the remoteVideoStateChangedOfUid method to get the state of the remote video stream.

    4. Add watermarks on the broadcasting video

    Adds the watermark function for users to add a PNG file to the local or CDN broadcast as a watermark. Adds the addVideoWatermark and clearVideoWatermarks methods to add and delete watermarks in a local live-broadcast. Adds the watermark parameter in the LiveTranscording interface to add watermarks in CDN broadcasts.

    Improvements

    1. Audio volume indication

    Improves the enableAudioVolumeIndication method. This method once enabled, sends the audio volume indication of the speaker in its callback at set intervals, regardless of whether anyone is speaking in the channel.

    2. Network quality detection during a session

    To meet the customers’ need for real-time network quality detection in the channel, the onNetworkQuality method improves its data accuracy.

    3. Last mile network quality detection before joining a channel

    To test if the customers’ network condition can support voice or video calls before joining the channel, the onLastmileQuality callback changes the detection from a fixed bitrate to the bitrate set by the customer in the setVideoProfile method to improve data accuracy. When the network condition is unknown, the SDK triggers this callback once every two seconds.

    4. Audio quality enhancement

    Improves the audio quality in scenarios that involve music playback.

    Issues Fixed

    • Occasional screen display abnormalities when a large number of audience members join as the host in a live-broadcast channel.

    Issues Fixed

    Occasional recording failures on some phones when a user leaves a channel and turns on the built-in recording device.

    Improvements

    Improves the performance of screen sharing by shortening the time interval between which users switch from screen sharing to the normal Communication or Live-broadcast profile.

    v2.1.2

    v2.1.2 is released on April 2, 2018.

    If you upgrade the SDK to v2.1.2 from a previous version, the live-broadcast video quality is better than the communication video quality in the same resolutions, resulting in the live broadcasts using more bandwidth.

    New Features

    Extends the setVideoProfile method to enable users to manually set the resolution, frame rate, and bitrate of the video.

    Issues Fixed

    Video freeze in DTX + AAC mode.

    v2.1.1

    v2.1.0 is released on March 7, 2018.

    New Features

    1. Voice Optimization

    Adds a scenario for the game chat room to reduce the bandwidth and cancel the noise with the setAudioProfile method.

    2. Enhance the audio effect input from the built-in microphone

    In an interactive broadcast scenario, the host can enhance the local audio effects from the built-in microphone with the setLocalVoiceEqualization and setLocalVoiceReverb methods by implementing the voice equalization and reverberation effects.

    3. Online statistics query

    Adds RESTful APIs to check the status of the users in the channel, the channel list of a specific company, and whether the user is an audience or a host:

    4. 17-way video

    Adds the support of 17-way video in interactive broadcasts, see:

    5. Video source customization

    Supports the default video-capturing features provided by the camera and the customized video source.

    6. Renderer customization

    Supports the default functions provided by the renderers to display the local and remote videos to meet your requirements. We provide a set of interfaces for customized renderers.

    7. Injecting an external video stream

    Adds the function of injecting an external video stream to an ongoing live broadcast.

    8. Camera focus change

    Adds an onCameraFocusAreaChanged callback to report to the app when the camera focus area changes.

    Improvements

    Improvement Description
    Video Freeze Rate Reduces the video freeze rate in the audience mode and for specific devices.
    Authentication Supports a new authentication mechanism. Each legacy Dynamic Key (Channel Key) corresponds to a single privilege (for example, joining a channel), but each token in the new authentication mechanism includes all privileges (for example, joining a channel, hosting in, and stream-pushing).
    Hardware Encoder Enables the H.264 hardware encoder on the Qualcomm, MTK, HiSilicon, and Orion chips.
    Hardware Encoder Improves the bitrate control for the hardware encoder.
    Billing Optimization Small video resolutions are charged according to the voice-only mode. For example, 16 × 16.

    Issues Fixed

    • Occasional playback noise on specific devices.
    • Occasional crackling voice playback on specific devices.

    • Adds the camera management function in the Communication and Live-broadcast profiles by adding the following API methods:

      Name Description
      isCameraZoomSupported Checks whether the device supports camera zoom.
      isCameraTorchSupported Checks whether the device supports camera flash.
      isCameraFocusSupported Checks whether the device supports camera manual focus.
      isCameraAutoFocusFaceModeSupported Checks whether the device supports camera auto-face focus.
      setCameraZoomFactor Sets the camera zoom ratio.
      getCameraMaxZoomFactor Gets the maximum zoom ratio of the camera.
      setCameraFocusPositionInPreview Sets the position for manual focus and activates focusing.
      setCameraTorchOn Sets the device to turn on the camera flash.
      setCameraAutoFocusFaceModeEnabled Sets the device to start auto-face focusing.
    • Supports external audio sources in the Communication and Live-broadcast profiles by adding the following API methods:

      Name Description
      setExternalAudioSource Enables the external audio source function.
      pushExternalAudioFrame Pushes the external audio frame to the Agora SDK.
    • Provides a set of RESTful APIs to ban a peer user from the server in the Communication and Live-broadcast profiles. Contact sales-us@agora.io to enable this function, if required.
    • Supports the following Android emulators: NOX, Lightning, and Xiaoyao.

    Improvements

    Optimizes the hardware encoder by supporting encoding resolutions as low as 64 x 64.

    Issues Fixed

    New Features

    • Adds the setAudioProfile method to set the audio parameters and scenarios
    • Adds the setLocalVoicePitch method to set the local voice pitch
    • Live Broadcast: Adds the setInEarMonitoringVolume method to adjust the volume of the in-ear monitor

    Improvements

    • Optimizes the audio at high bitrates.
    • Live Broadcast: The audience can view the host within one second in a single-stream mode (226 ms on average, and 204 ms under good network conditions).
    • Adds the ability to reduce the bandwidth.
      • Before v1.14: If you muted the audio of a specific user, the network still sent the stream.
      • Starting from v1.14: If you mute the audio of a specific user, the network will not send the stream of the user to reduce the bandwidth.
    • Accurate control over the bitrate:
      • Before v1.14: Inaccurate control over the bitrate often caused huge fluctuations, leading to network congestion and higher rates of packet and frame loss. This affected the accuracy of the bandwidth estimation module, especially under poor network conditions.
      • Starting from v1.14: Accurate control over the bitrate prevents huge fluctuations avoiding network congestion and shortening the transmission latency.

    Issues Fixed

    Camera related issues on Android devices.
