[regression] JPEG Encode Broken since 059fc2d9da53

[U. Artie Eoff]

Summary of the bug:

JPEG encode with mjpeg_vaapi or mjpeg_qsv broken since:

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.

How to reproduce:

mjpeg_vaapi:

% ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 \
  -f lavfi -i yuvtestsrc=duration=5:size=qcif:rate=30 \
  -vf "format=nv12,hwupload" -c:v mjpeg_vaapi \
  -y output.mjpeg
