How to "compress" saved video file using VideoFileRenderer ?

[Kushtrim Pacaj]

I tried using VideoFileRenderer, but looks like it's saving all frames directly to the file, and the file reaches 80MB for just 4s of recording in 640x480 resolution.

To make a smaller file, looks like something like this would have to be done. https://en.wikipedia.org/wiki/Video_compression_picture_types#Predicted_frames/slices_(P-frames/slices) 

Tried using MediaCodec class, and using some sample code from examples such as https://www.bigflake.com/mediacodec/EncodeAndMuxTest.java.txt , but I haven't been able to achieve a result, since I haven't dealt with media encoding/decoding before.

I'd appreciate any help anyone could provide regarding this.

I had the same problem. Try to consume this class https://github.com/cloudwebrtc/flutter-webrtc/blob/master/android/src/main/java/com/cloudwebrtc/webrtc/record/VideoFileRenderer.java

I managed to record and compress the video but not audio. If anyone know how to record webrtc call audio please help me.
