I tried first with fdk_aac, it sounds a little better but still skips a lot
and sounds out of sync
ffmpeg -f avfoundation -i "1:0" -r 25 -c:v mpeg4 -c:a libfdk_aac -b:a
128k -ar 44100 screen-default-mpeg4-fdk-aac.mp4
Here is output file
I also tried without fdk_aac and similar output: skips a lot and sounds out
ffmpeg -f avfoundation -i "1:0" -r 25 -c:v mpeg4 screen-nofdk.mp4
Here is output file:
