All three have the same problem. Here are the commands and the corresponding files produced. The complete output is at the end of this email. Please let me know if I should try any other command or with other options. framerate: 30 ./ffmpeg -f avfoundation -video_size 640x480 -framerate 30 -i "1:0" -c:v mpeg4 -c:a aac -strict -2 -r 30 ffmpeg-git-head-30.mp4 https://www.dropbox.com/s/hf6zqxwq7y394yd/ffmpeg-git-head-30.mp4?dl=1 framerate:25 ./ffmpeg -f avfoundation -video_size 640x480 -framerate 25 -i "1:0" -c:v mpeg4 -c:a aac -strict -2 -r 25 ffmpeg-git-head-25.mp4 https://www.dropbox.com/s/k1ijq5zyzfqgewf/ffmpeg-git-head-25.mp4?dl=1 framerate:15 ./ffmpeg -f avfoundation -video_size 640x480 -framerate 15 -i "1:0" -c:v mpeg4 -c:a aac -strict -2 -r 15 ffmpeg-git-head-15.mp4 https://www.dropbox.com/s/0zptd9e8alvf050/ffmpeg-git-head-15.mp4?dl=1 Is -ar 44100 needed to reproduce the issue?
