2019-02-08avcodec/h264_parse: no need check ref list1 for P slices.Decai Lin
This is robust for some corner case there is incorrect list1 count in pps header, but it's a P slice and can be decoded well. Signed-off-by: Decai Lin <decai.lin@intel.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

2017-09-08libavcodec/h264_parse: don't use uninitialized value when chroma_format_idc==0Mark Wachsler
When parsing a monochrome file, chroma_log2_weight_denom was used without being initialized, which could lead to a bogus error message being printed, e.g. [h264 @ 0x61a000026480] chroma_log2_weight_denom 24576 is out of range It also could led to warnings using AddressSanitizer.

2016-06-21h264: add H264_ prefix to the NAL unit typesAnton Khirnov
This will prevent conflicts e.g. in code that deals with both h264 and hevc.
2016-06-21h264: move the parameter set definitions to a new header fileAnton Khirnov
The PS parsing code is independent from the decoder, so it makes more sense for it to have its own separate header.
2016-06-21h264: create a new header for common h264 definitionsAnton Khirnov
Move the NAL unit types into it. This will allow to stop including the whole decoder-specific h264dec.h in some code that is unrelated to the decoder and only needs some enum values.
2016-06-21h264: rename h264.[ch] to h264dec.[ch]Anton Khirnov
This is more consistent with the naming of other decoders.

* commit '98c97994c5b90bdae02accb155eeceeb5224b8ef': h264: decouple extradata parsing from the decoder Main changes: - move get_avc_nalsize() inside h264_parser.c and make it use H264ParseContext instead of H264Context. This helps fixing fate-flv-demux. - Also use is_avc/nal_length_size from the H264ParseContext in various places instead of the H264Context one as that's the fields now filled by ff_h264_decode_extradata() - h264_parse: dont fail decode_extradata_ps() due to nal split failure. Change by Michael to fix decoding of h264/ref_10.avi. Merged-by: Clément Bœsch <u@pkh.me> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
2016-06-18lavc/h264_parse: remove tabs introduced in a2922b5dClément Bœsch
2016-06-12h264: move initialising the explicit pred weight table for MBAFFAnton Khirnov
Currently it's done in the code that initialises the ref list for MBAFF, which is not a logical place for it. Move it to the function that parses the pred table from the bitstream, which is analogous to what is done for the implicit weight table as well.
