Wan-Teh Chang	99c5ac2039	avcodec/h264: Declare the local variable decode_chroma as const. ff_h264_decode_mb_cabac() and ff_h264_decode_mb_cavlc() are very long functions. Declaring decode_chroma as const makes it clear the variable doesn't change after initialization.

Anton Khirnov	9df889a5f1	h264: rename h264.[ch] to h264dec.[ch] This is more consistent with the naming of other decoders.	9 years ago

Anton Khirnov	6e92181bf8	h264: pass just the PPS to get_chroma_qp() It does not need the whole context. This will simplify the following commit.	9 years ago
Diego Biurrun	52567e8198	get_bits: Drop some TRACE-level debug code It will not be provided by the new bit reader anyway.	9 years ago

Diego Biurrun	c11c693acc	h264: Drop broken trace debug output	9 years ago
Anton Khirnov	3176217c60	h264: decouple h264_ps from the h264 decoder Make the SPS/PPS parsing independent of the H264Context, to allow decoupling the parser from the decoder. The change is modelled after the one done earlier for HEVC. Move the dequant buffers to the PPS to avoid complex checks whether they changed and an expensive copy for frame threads.	9 years ago
