Hello everyone! I am trying to implement RemoteVideoTrack recording. I am using https://github.com/flutter-webrtc/flutter-webrtc/blob/main/android/src/main/java/com/cloudwebrtc/webrtc/record/VideoFileRenderer.java as an example. But now there is a problem with video encoding, the files as a result are always small and have only black content. Has anyone tried to encode VideoFrame to a format suitable for MediaMuxer? What could be the problem in my case?
