 commit 059fc2d9da5364627613fb3e6424079e14dbdfd3

     avcodec/mjpegenc: Include all supported pix_fmts in mpegenc pix_fmts

     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.

 I have not tested other jpeg encoder plugins.
