◆ STANDARD_BITRATE

final int io.agora.rtc.video.VideoEncoderConfiguration.STANDARD_BITRATE = 0
static

The standard bitrate mode. In this mode, the bitrates under the Live Broadcast and Communication profiles differ:

  • In the Communication profile, the video bitrate is the same as the base bitrate.
  • In the Live Broadcast profile, the video bitrate is twice the base bitrate.

◆ COMPATIBLE_BITRATE

final int io.agora.rtc.video.VideoEncoderConfiguration.COMPATIBLE_BITRATE = -1
static

The compatible bitrate mode. In this mode, the bitrate stays the same regardless of the profile. If you choose this mode for the Live Broadcast profile, the video frame rate may be lower than the set value.

◆ DEFAULT_MIN_BITRATE

final int io.agora.rtc.video.VideoEncoderConfiguration.DEFAULT_MIN_BITRATE = -1
static

Use the default minimum bitrate.

◆ DEFAULT_MIN_FRAMERATE

final int io.agora.rtc.video.VideoEncoderConfiguration.DEFAULT_MIN_FRAMERATE = -1
static

The default minimum frame rate.

◆ dimensions

VideoDimensions io.agora.rtc.video.VideoEncoderConfiguration.dimensions

The video frame dimension, which is used to specify the video quality and measured by the total number of pixels along a frame's width and height. Users can either set the resolution manually or choose from the following options:

Note
  • The value of the dimension does not indicate the orientation mode of the output ratio. For how to set the video orientation, see ORIENTATION_MODE.
  • Whether 720p+ can be supported depends on the device. If the device cannot support 720p, the frame rate will be lower than the one listed in the table.

◆ frameRate

int io.agora.rtc.video.VideoEncoderConfiguration.frameRate

The video frame rate (fps). Users can either set the frame rate manually or choose from the following options. We do not recommend setting this to a value greater than 30.

◆ minFrameRate

int io.agora.rtc.video.VideoEncoderConfiguration.minFrameRate

The minimum video encoder frame rate (fps). The default value is DEFAULT_MIN_FRAMERATE(-1) (the SDK uses the lowest encoder frame rate).

Since
v2.4.0.

For information on scenarios and considerations, see Set the Video Profile Under Advanced Guides.

◆ bitrate

int io.agora.rtc.video.VideoEncoderConfiguration.bitrate

Bitrate of the video (Kbps). Refer to the table below and set your bitrate. If you set a bitrate beyond the proper range, the SDK automatically adjusts it to a value within the range. You can also choose from the following options:

  • STANDARD_BITRATE = 0: (Recommended) The standard bitrate mode. In this mode, the bitrates differ between the Live Broadcast and Communication profiles:
    • In the Communication profile, the video bitrate is the same as the base bitrate.
    • In the Live Broadcast profile, the video bitrate is twice the base bitrate.
  • COMPATIBLE_BITRATE = -1: The compatible bitrate mode. In this mode, the bitrate stays the same regardless of the profile. If you choose this mode for the Live Broadcast profile, the video frame rate may be lower than the set value.

Agora uses different video codecs for different profiles to optimize the user experience. For example, the Communication profile prioritizes the smoothness while the Live Broadcast profile prioritizes the video quality (a higher bitrate). Therefore, We recommend setting this parameter as STANDARD_BITRATE = 0.

960 × 720 15 910 1820
960 × 720 30 1380 2760
Note
The base bitrate in this table applies to the Communication profile. The Live Broadcast profile generally requires a higher bitrate for better video quality. We recommend setting the bitrate mode as STANDARD_BITRATE = 0. You can also set the bitrate as the base bitrate value × 2.

◆ minBitrate

int io.agora.rtc.video.VideoEncoderConfiguration.minBitrate
Since
v2.3.2. The minimum encoding bitrate (Kbps). The Agora 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. That said, unless you have special requirements for image quality, Agora does not recommend changing this value.
Note
This parameter applies to the Live Broadcast profile only.

◆ orientationMode

ORIENTATION_MODE io.agora.rtc.video.VideoEncoderConfiguration.orientationMode

The orientation mode. See ORIENTATION_MODE.

◆ degradationPrefer

DEGRADATION_PREFERENCE io.agora.rtc.video.VideoEncoderConfiguration.degradationPrefer

The video encoding degradation preference under limited bandwidth:

Since
v2.4.0.

For detailed information on the prefrence, see DEGRADATION_PREFERENCE.
