Diego Biurrun	d4c2103bd3	golomb: Convert to the new bitstream reader	8 years ago
Anton Khirnov	5c2fb561d9	h264: add H264_ prefix to the NAL unit types This will prevent conflicts e.g. in code that deals with both h264 and hevc.	9 years ago
Anton Khirnov	b24dafe105	lavc: drop unnecessary h264dec.h includes	9 years ago
Anton Khirnov	f638b67e57	h264: move the parameter set definitions to a new header file The PS parsing code is independent from the decoder, so it makes more sense for it to have its own separate header.	9 years ago
Anton Khirnov	251cbb4400	h264: create a new header for common h264 definitions 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.	9 years ago
Anton Khirnov	9df889a5f1	h264: rename h264.[ch] to h264dec.[ch] This is more consistent with the naming of other decoders.	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	02cd8bb9cb	h264: Clean up #includes	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
Anton Khirnov	5bf3c0fa49	h264: drop the now unused per-slice H264Contexts	10 years ago
Anton Khirnov	3178f4d33f	h264: move rbsp_buffer into the per-slice context	10 years ago
Anton Khirnov	f42485dbce	h264: use a separate GetBitContext for slice data	10 years ago

Anton Khirnov	9404a47a2d	h264: move parser-only variables to their own context	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
Gabriel Dume	f929ab0569	cosmetics: Write NULL pointer equality checks more compactly Signed-off-by: Diego Biurrun <diego@biurrun.de>	11 years ago
Ben Avison	db7f1c7c5a	h264: Move start code search functions into separate source files. This permits re-use with parsers for codecs which use similar start codes. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Vittorio Giovara	e0c16e4e32	mpegvideo: move mpegvideo formats-related defines to mpegutils.h	11 years ago
Vittorio Giovara	dc971acf4a	h264_parser: use enum values in h264_find_frame_end()	11 years ago
Vittorio Giovara	73e8fab31d	h264: print values in case of error Also make error style consistent and drop redundant information.	11 years ago

Yusuke Nakamura	4baba6c813	h264_parser: Fix POC parsing for the case where MMCO_RESET is present. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Yusuke Nakamura	b81dbd6cb7	h264_parser: Fix POC parsing for the case where MMCO_RESET is absent. The prev_ values were not set after parsing POC. Increase length of the buffer decoded to parse enough safely. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Ben Avison	218d6844b3	h264dsp: Factorize code into a new function, h264_find_start_code_candidate This performs the start code search which was previously part of h264_find_frame_end() - the most CPU intensive part of the function. By itself, this results in a performance regression: Before After Mean StdDev Mean StdDev Change Overall time 2925.6 26.2 3068.5 31.7 -4.7% but this can more than be made up for by platform-optimised implementations of the function.

Ben Avison	7a82022ee2	h264_parser: Initialize the h264dsp context in the parser as well Each AVStream struct for an H.264 elementary stream actually has two copies of the H264DSPContext struct (and in fact all the other members of H264Context as well): ((H264Context ) ((AVStream )st)->codec->priv_data)->h264dsp ((H264Context ) ((AVStream )st)->parser->priv_data)->h264dsp but only the first of these was actually being initialised. This prevented the addition of platform-specific implementations of parser-related functions. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Diego Biurrun	088f38a4f9	avcodec: Drop unnecessary ff_ name prefixes from static functions	12 years ago
Martin Storsjö	f1e9398621	lavc: Rename avpriv_mpv_find_start_code after moving out from mpegvideo Also move the declaration to internal.h, and add restrict qualifiers to the declaration (as in the implementation). Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	2c54155407	h264: deMpegEncContextize Most of the changes are just trivial are just trivial replacements of fields from MpegEncContext with equivalent fields in H264Context. Everything in h264* other than h264.c are those trivial changes. The nontrivial parts are: 1) extracting a simplified version of the frame management code from mpegvideo.c. We don't need last/next_picture anymore, since h264 uses its own more complex system already and those were set only to appease the mpegvideo parts. 2) some tables that need to be allocated/freed in appropriate places. 3) hwaccels -- mostly trivial replacements. for dxva, the draw_horiz_band() call is moved from ff_dxva2_common_end_frame() to per-codec end_frame() callbacks, because it's now different for h264 and MpegEncContext-based decoders. 4) svq3 -- it does not use h264 complex reference system, so I just added some very simplistic frame management instead and dropped the use of ff_h264_frame_start(). Because of this I also had to move some initialization code to svq3.
