Research direction
Investigate the FrameGrabber class in the javacv repository, particularly the audio decoding logic around line where audio format is determined. Check if G722 codec is handled differently from MP2 in FFmpeg bindings. Review comments in the issue for any hints from maintainers about expected behavior. Consider testing with sample G722 audio files to reproduce the bug.
