Comment (by jonnyburger):

 I tried on a M2 Mac on a copy of FFmpeg (`N-111888-gfc993e7a53`), enabled
 with `--enable-videotoolbox`, as an additional step of my repro:


 {{{
 ffmpeg -hwaccel videotoolbox -i out.mov out.mp4 -y
 }}}

 It seems to have picked up, since values other than `videotoolbox` throw
 an error.

 The video transcodes without any flickering, although quality is degraded.

 I used ffmpeg to convert a video, because according of my knowledge,
 ffplay does not support the hwaccel flag.
