The pix_fmts of the LJPEG encoder already contain all supported pixel formats (including the ones only supported when strictness is unofficial or less); yet the check in ff_encode_preinit() ignored this list in case strictness is unofficial or less. But the encoder presumed that it is always applied and blacklists some of the entries in pix_fmts when strictness is > unofficial. The result is that if one uses an entry not on that list and sets strictness to unofficial, said entry passes both checks and this can lead to segfaults lateron (e.g. when using gray). Fix this by removing the exception for LJPEG in ff_encode_preinit(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
