avdevice/v4l2: Remove av_assert0 when format not supported
Before this commit an av_assert0 would fail if a v4l2 device did not support a target format. For example, ./ffmpeg -f v4l2 -codec:v h264 -i /dev/video0 -f mpegts - would signal an abort if /dev/video0 did not support h264. The new behaviour is to return an AVERROR(EINVAL) error code. An av_assert0 has been added to verify this return. Fixes #6629 Signed-off-by:Andriy Gelman <andriy.gelman@gmail.com> Reviewed-by:
