Matthieu Bouron	0ea58059d6	lavc/h264_ps: add ff_h264_ps_uninit and use it	9 years ago
Clément Bœsch	38a2d9aeec	lavc/h264_parser: replace AVCodecContext with logging ctx in scan_mmco_reset()	9 years ago
Clément Bœsch	4fdea02d68	lavc/h264: add a logging ctx to ff_h264_pred_weight_table()	9 years ago
Clément Bœsch	34ec084b84	lavc/h264: move history parsing variable to H264ParseContext This makes h264_find_frame_end() not depend on H264Context anymore.	9 years ago
Clément Bœsch	48ea5433c8	lavc/h264_parser: pass logctx to h264_find_frame_end() This helps removing the H264Context from the H264ParseContext.	9 years ago
Vittorio Giovara	41ed7ab45f	cosmetics: Fix spelling mistakes Signed-off-by: Diego Biurrun <diego@biurrun.de>	9 years ago
Anton Khirnov	72da8d9bb2	h264_parser: remove the remaining dependencies on the h264 decoder	9 years ago
Anton Khirnov	98c97994c5	h264: decouple extradata parsing from the decoder This will allow decoupling the parser from the decoder.	9 years ago
Anton Khirnov	728d90a0c1	h264: decouple h264_sei from the h264 decoder Make the SEI parsing independent of the H264Context, to allow decoupling the parser from the decoder.	9 years ago
Anton Khirnov	c8dcff0cdb	h264: factor out calculating the POC count into a separate file This will allow decoupling the parser from the decoder.	9 years ago
Anton Khirnov	113aeee6ae	h264_parser: move the H264DSPContext to the parser context	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
Anton Khirnov	44d16df413	h264_parser: eliminate H264SliceContext usage It is no longer needed for anything.	9 years ago
Anton Khirnov	a6e27f7add	h264: factor out parsing the reference count into a separate file This will allow decoupling the parser from the decoder.	9 years ago
Anton Khirnov	e9f884416c	h264: move reading direct_spatial_mv_pred out of ff_set_ref_count() It has nothing to do with the reference count and so does not belong in this function.	9 years ago
Anton Khirnov	8d0cc8ca97	h264_parser: switch to h2645_parse for NAL unescaping Remove now unused ff_h264_decode_nal().	9 years ago
Anton Khirnov	e481458bc3	h264: factor out pred weight table parsing into a separate file This will allow decoupling the parser from the decoder.	9 years ago
Diego Biurrun	a7da517f6a	h264data: Move all data tables from a header to a .c file	9 years ago
Diego Biurrun	02cd8bb9cb	h264: Clean up #includes	9 years ago
Mark Harris	c51c08e0e7	avcodec: Use get_ue_golomb_long() when needed get_ue_golomb() cannot decode values larger than 8190 (the maximum value that can be golomb encoded in 25 bits) and produces the error "Invalid UE golomb code" if a larger value is encountered. Use get_ue_golomb_long() instead (which supports 63 bits, up to 4294967294) when valid h264/hevc values can exceed 8190. This updates decoding of the following values: (maximum) first_mb_in_slice 36863* for level 5.2 abs_diff_pic_num_minus1 131071 difference_of_pic_nums_minus1 131071 idr_pic_id 65535 recovery_frame_cnt 65535 frame_packing_arrangement_id 4294967294 frame_packing_arrangement_repetition_period 16384 display_orientation_repetition_period 16384 An alternative would be to modify get_ue_golomb() to handle encoded values of up to 49 bits as was done for get_se_golomb() in `a92816c`. In that case get_ue_golomb() could continue to be used for all of these except frame_packing_arrangement_id. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Diego Biurrun	8161220eee	h264_parser: Rename close() to h264_close() At least on AIX it conflicts with the close() libc function from unistd.h.	9 years ago

Zhaoxiu Zeng	2a72b1664d	avcodec/h264: use avpriv_find_start_code() in h264_split() This also allows replacing several literal numbers by named constants And it should be faster, the function is not speed relevant though as it is generally only called a few times at the streams start.

Michael Niedermayer	ccaa5dcb31	avcodec/h264_parser: Rename close() This avoids a potential conflict with the equally named function for closing files It also could reduce confusion in debugger backtraces Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

John Stebbins	1b66726906	h264_parser: don't stop on SPS_EXT in split Add SPS_EXT, SEI, and subset SPS to codes that are skipped during split. These codes can come before the PPS and results in incomplete extradata.	10 years ago
