Currently said list contains only the pixel formats that are always supported irrespective of the range and the value of strict_std_compliance. This makes the MJPEG encoder an outlier as all other codecs put all potentially supported pixel formats into said list and error out if the chosen pixel format is unsupported. This commit brings it therefore in line with the other encoders. The behaviour of fftools/ffmpeg_filter.c has been preserved. A more informed decision would be possible if colour range were available at this point, but it isn't. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
