Michael Niedermayer	ca9025f374	avcodec/dpx: fix off by 1 in bits_per_color check Fixes: CID1476303 Bad bit shift operation Fixes: 34871/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_DPX_fuzzer-6331163028357120 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	3 years ago
Andreas Rheinhardt	a247ac640d	avcodec: Constify AVCodecs Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.
