Comment (by evanrinehart):

 I tried both the command that is the problem in #4079 and both suggested
 workarounds, rgb24 and yuv444p and they both produce the same issue I am
 having with a full screen capture (though the output is cropped). You can
 see the problem by looking at the attached .mov or I can upload the
 cropped version.

 Command I used:
 ffmpeg -f avfoundation -pix_fmt uyvy422 -video_device_index 1
 -audio_device_index 0 -i "" -r 60 -c:v libx264 -crf 0 -vf
 format=yuv444p,crop=426:240:507:339 -c:a pcm_s16le -ar 48000 out.mov

 Because others seem to have no trouble on "normal" resolutions I think my
 circumstances are caused by the 1366x768 resolution. I am still looking at
 the avfoundation.m source file to try and understand where the bad width
 is coming from.

 I don't really consider this issue closed.
