Agora Native SDK 3.5.1 was released on 14 October 2021.
New Features ✨
Super Resolution (beta) 🪟
Effectively boost the resolution of a remote user's video seen by the local user.
You can call enableRemoteSuperResolution to enable super resolution, specifying the remote user's uid. Make sure the AgoraSuperResolutionExtension framework is also included in your project.
Background Blurring 😶🌫️
Virtual backgrounds was added to the SDK since 3.5.0, and now to further enrich that, there is an option to apply a blur to the background. Set the type of the custom background image to AgoraVirtualBackgroundBlur, apply a blur_degree, and the background will be blurred.
Device Flash 📸
isCameraTorchSupported and setCameraTorchOn have been added to the C++ APIs for both iOS and Android.
Media Stream Relay Pausing/Resuming ⏯
Methods have been added to quickly pause and resume cross-channel media stream relays; as well as additional delegate methods to check if the pause and resume commands were successful.
Pushing External Audio to a Specified Position 🎤
pushExternalAudioFrameRawData and pushExternalAudioFrameSampleBuffer have been updated to have an additional parameter. This parameter, sourcePos, allows you to push the external audio frames to one of three positions: after audio capture, before audio encoding, or before local playback.
Additionally, setExternalAudioSourceVolume has also been added; allowing you to set the volume of external audio frames at a specified position.
Music and Audio File Updates 🎶
Playback speed, audio track, and channel mode of a music file can be set in code.
This update deprecates getAudioMixingDuration method in favour of getAudioFileInfo. getAudioFileInfo still gets information such as duration, but returns it in an AgoraRtcAudioFileInfo object in the didRequestAudioFileInfo delegate method, found here.
Improvements
5G Quality Testing ⚡️
When monitoring the connection quality of a device, a new property has been added to the AgoraNetworkType enum, AgoraNetworkTypeMobile5G(6), or .mobile5G with Swift, and NETWORK_TYPE_MOBILE_5G on Android.
