OpenGL + MediaRecorder.VideoEncoder.AV1 - a freezing video (like very low fps)

[anonym24]

Android declares that AV1 video encoder is supported for Android 14+

Before I pass frames to MediaRecorder I process them with OpenGL:

recorderWindowSurface = WindowSurface(eglCore, recorderSurface, true)
recorderWindowSurface.makeCurrent()

I tried AV1 codec on Samsung S22 Ultra Android 14 and Android MediaRecorder:

mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.AV1)                
recorderSurface = MediaCodec.createPersistentInputSurface()
mediaRecorder.setInputSurface(recorderSurface)

I tried to play a recording video but it plays very freezing / lagging.

I noticed that EglSurfaceBase.swapBuffers() (source) takes a lot of CPU time right now

164 ms
151 ms
153 ms
163 ms
150 ms
160 ms
158 ms
145 ms
158 ms
173 ms
191 ms

Did someone tried it on their devices, does it work well or similar results?

MediaRecorder.VideoEncoder.H264, MediaRecorder.VideoEncoder.HEVC - works without issues, same parameters (bitrate, full hd resolution, fps 20..30, nothing special).

EglSurfaceBase.swapBuffers() in this case takes:

8 ms 
10 ms
6 ms 
6 ms 
4 ms 
4 ms 
3 ms 
2 ms
