# Communicate with Video SDK (/en/realtime-media/iot/reference/communicate-with-rtc-sdk) > For AI agents: see the complete documentation index at [llms.txt](/llms.txt). If your business requires not only high-quality audio and video transmission, but also easy integration, low memory usage, and low power consumption, for applications such as smart cameras and smart doorbells, Agora recommends that you use the Video SDK with the IoT SDK. The following table shows the data formats supported when the IoT SDK communicates with the Video SDK (v4.x): | Video SDK Type | Supported formats | | :------------------------------------------------------------------------------------------------- | :----------------------------------------------- | | Native/third-party frameworks: Android, iOS/macOS, Windows, Electron, Unity, Flutter, React Native | Audio: G722, G711, Opus, AAC; Video: H.264, JPEG | | Web (v4.x) | Audio: G722, G711, Opus; Video: H.264 | | Embedded systems | Audio: G711, Opus; Video: H.264, JPEG | The sending and receiving ends can communicate with each other only if the set data format is consistent and complies with the above table. The following sections describe how to set the audio and video data formats in the SDKs. ## Set up IoT SDK [#set-up-iot-sdk] **Audio** IoT SDK only supports mono audio data, and the data sending interval is 20 ms. To send and receive `AAC` audio data, set `audio_frame_info_t.data_type` to `AUDIO_DATA_TYPE_AACLC` or `AUDIO_DATA_TYPE_HEAAC` and specify the corresponding data size when calling the `agora_rtc_send_audio_data` method. The size of `AAC` audio data needs to be resolved by the user. **Video** In IoT SDK, `H.264` video data is sent and received by default. To send and receive `JPEG` video data, when calling the `agora_rtc_send_video_data` method, set `video_frame_info_t.data_type` to `VIDEO_DATA_TYPE_GENERIC_JPEG`. ## Set up Video SDK for Native/third-party frameworks [#set-up-video-sdk-for-nativethird-party-frameworks] **Audio** In Native/third-party framework SDKs (v4.x), `Opus` or `AAC` audio data is sent and received by default. To send and receive `G722` or `G711` audio data, use the following methods: | Video SDK type | G722 | G711 (PCMA) | G711 (PCMU) | | -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------- | | Android | `agoraEngine.setAudioProfile(6)` or `agoraEngine.setParameters("{\"che.audio. custom_payload_type\":9}")` | `agoraEngine.setParameters("{\"che.audio. custom_payload_type\":8}")` | `agoraEngine.setParameters("{\"che.audio. custom_payload_type\":0}")` | | iOS/macOS | `agoraKit.setAudioProfile(6)` or `agoraKit.setParameters("{\"che.audio. custom_payload_type\":9}")` | `agoraKit.setParameters("{\"che.audio. custom_payload_type\":8}")` | `agoraKit.setParameters("{\"che.audio. custom_payload_type\":0}")` | | Windows | `agoraEngine->setAudioProfile(6)` or `agora::base::AParameter apm(agoraEngine); apm->setParameters("{\"che.audio. custom_payload_type\":9}")` | `agora::base::AParameter apm(agoraEngine);apm->agoraEngine->setParameters("{\"che.audio. custom_payload_type\":8}")` | `agora::base::AParameter apm(agoraEngine);apm->agoraEngine->setParameters("{\"che.audio. custom_payload_type\":0}")` | | Electron | `this.agoraEngine?.setAudioProfile(6)` or `this.agoraEngine?.setParameters("{\"che.audio. custom_payload_type\":9}")` | `this.agoraEngine?.setParameters("{\"rtc.audio. custom_payload_type\":8}")` | `this.agoraEngine?.setParameters("{\"rtc.audio. custom_payload_type\":0}")` | | Unity | `await agoraEngine.setAudioProfile(profile: AudioProfileType.audioProfileIot)` or `await agoraEngine.setParameters("{\"che.audio. custom_payload_type\":9}")` | `await agoraEngine.setParameters("{\"che.audio. custom_payload_type\":8}")` | `await agoraEngine.setParameters("{\"che.audio. custom_payload_type\":0}")` | | Flutter | `await agoraEngine.setAudioProfile(profile: AudioProfileType.audioProfileIot)` or `await agoraEngine.setParameters("{\"che.audio. custom_payload_type\":9}")` | `await agoraEngine.setParameters("{\"che.audio. custom_payload_type\":8}")` | `await agoraEngine.setParameters("{\"che.audio. custom_payload_type\":0}")` | | React Native | `await agoraEngine.current?.setAudioProfile(6)` or `await agoraEngine.current?.setParameters("{\"che.audio. custom_payload_type\":9}")` | `await agoraEngine.current?.setParameters("{\"che.audio. custom_payload_type\":8}")` | `await agoraEngine.current?.setParameters("{\"che.audio. custom_payload_type\":0}")` | **Video** In Native/third-party framework SDKs (v4.x), `H.264` video data is sent and received by default. To send and receive `JPEG` video data, use the following methods: | Video SDK type | Method | | -------------- | :------------------------------------------------------------------------------------------------------------ | | Android | `agoraEngine.setParameters("{\"engine.video.codec_type\": \"20\"}")` | | iOS/macOS | `agoraKit.setParameters("{\"engine.video.codec_type\": \"20\"}")` | | Windows | `agora::base::AParameter apm(agoraEngine);`
`apm->setParameters("{\"engine.video.codec_type\": \"20\"}")` | | Electron | `this.agoraEngine.setParameters("{\"engine.video.codec_type\": \"20\"}");` | | Unity | `agoraEngine.SetParameters("{\"engine.video.codec_type\": \"20\"}");` | | Flutter | `await agoraEngine.setParameters("{\"engine.video.codec_type\": \"20\"}");` | | React Native | `this.engine.setParameters("{\"engine.video.codec_type\": \"20\"}");` | ## Set up Video SDK for Web [#set-up-video-sdk-for-web] **Audio** In Video SDK for Web (v4.x), `Opus` audio data is sent and received by default. To send and receive `G722`, `G711` audio data, call the following method: * G711 (PCMA): `AgoraRTC.createClient({mode: "live", codec: "h264", audioCodec: "pcma"})` * G711 (PCMU): `AgoraRTC.createClient({mode: "live", codec: "h264", audioCodec: "pcmu"})` * G722: `AgoraRTC.createClient({mode: "live", codec: "h264", audioCodec: "g722"})` Only the Web SDK version 4.9.0 or higher supports setting the audio encoding format. **Video** In Web SDK (v4.x), `VP8` video data is sent and received by default. You call `createClient` to set the video data format to `"h264"`. ## Set up Video SDK for embedded systems [#set-up-video-sdk-for-embedded-systems] In Video SDK for embedded systems, `Opus` audio data and `H.264` video data are sent and received by default. If you want to receive `JPEG` video data or send and receive `G711` audio data, contact [sales-us@agora.io](mailto\:sales-us@agora.io) for activation. Video SDK for embedded systems does not support sending `JPEG` video data.
