[FFmpeg-devel] [PATCH] H264 parser fix

[Howard Chu]

When decoding an H264 stream that uses global headers, you get an endless 
stream of "non-existing PPS referenced" messages. This message comes from 
h264_parser.c, and it happens because it's using an H264Context hanging off 
the AVCodecParserContext, which is separate from the H264Context hanging off 
the AVCodecContext, and only the AVCodecContext contains the extradata that 
provides the PPS and SPS.

This patch is admittedly a hack, but it stops the error. It just checks in the 
AVCodecContext if the PPS wasn't found in the AVCodecParserContext.
