THis is not a question related to development of FFmpeg but a question
about FFmpeg usage, therefore it belongs to the ffmpeg-user mailing
list: https://lists.ffmpeg.org/mailman/listinfo/ffmpeg-user/
Please post such questions there in the future as they're off-topic
here.

oppression to develop psychic muscles.
