Евгений, а вы можете проверить это еще раз со сборкой выше,
работает ли оно если указать --demuxer-lavf-format=video4linux2 ?
$ mpv --demuxer-lavf-format=video4linux2
--demuxer-lavf-o-set=input_format=mjpeg av://v4l2:/dev/video0
$ mpv --demuxer-lavf-format=video4linux2 av://v4l2:/dev/video0
--profile=low-latency --untimed
?
