Ronald S. Bultje	27209bb108	h264: mark some MC functions with av_always_inline instead of inline. This actually causes them to be inlined, leading to a significant speedup (1-1.5% in my measurements).	13 years ago
Ronald S. Bultje	05fb63f5a0	H264: have hl_motion() and its callees take a chroma_idc argument.	13 years ago
Ronald S. Bultje	c2d337429c	H264: change weight/biweight functions to take a height argument. Neon parts by Mans Rullgard <mans@mansr.com>.	13 years ago

Baptiste Coudurier	76741b0e56	h264: 4:2:2 intra decoding support Signed-off-by: Diego Biurrun <diego@biurrun.de> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Steven Walters	27237d524e	w32threads: support for frame multithreading Replace our incomplete w32threads implementation with x264's pthreads w32threads wrapper. Relicensed to LGPL with kind permission by Pegasys Inc. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Mans Rullgard	318efbfc10	h264: change unsupported bit depth message to error level Unsupported bit depth is certainly an error the user will want to know about. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Laurent Aimar	4c7a232fc8	h264: reset h->ref_count in case of errors in ff_h264_decode_ref_pic_list_reordering() Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Mans Rullgard	4d1418cd4f	h264: fix signed overflows in x*0x01010101 expressions Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Michael Niedermayer	14c21c1ff5	H264: Only wait before triggering ff_thread_setup_complete() until the next slice that contains a start-of-field/frame macroblock This allows concurrent decoding of the last field/frame, rather than only the last slice, of data packets with multiple NAL units packed together. This will fix the slowdown reported in e.g. bug 52. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Ronald S. Bultje	4418aa9cb3	h264: correct implicit_weight for field-interlaced pictures.	13 years ago
Laurent Aimar	d1186ff72d	h264: check for out of bounds reads in ff_h264_decode_extradata(). Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Diego Biurrun	95a06eb4d5	Fix assert() calls that need updates after FF_COMMON_FRAME macro elimination. This fixes build failures with -DDEBUG in CPPFLAGS.	13 years ago
Luca Barbato	22141917a9	Revert "h264: Properly set coded_{width, height} when parsing H.264." This reverts commit `b47904d158`. coded_{width, height} overwrites width and height in avcodec_open and it currently just report the non-lowres size.	13 years ago
Jeff Downs	6581e161c5	h264: fix PCM intra-coded blocks in monochrome case Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Jeff Downs	87cf70eb23	h264: correct implicit weight table computation for long ref pics Correct computation of implicit weight tables when referencing pictures that are marked for long reference. Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Dustin Brody	bac3ab13ea	h264: notice memory allocation failure Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Dustin Brody	12fe759423	h264: propagate error return values for AV_LOG_ERROR-triggering events Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	13 years ago
Mans Rullgard	5cc2600964	dsputil: create 16/32-bit dctcoef versions of some functions High bitdepth H.264 needs 32-bit transform coefficients, whereas dnxhd does not. This creates a conflict with the templated functions operating on DCTELEM data. This patch adds a field allowing the caller to choose the element size in dsputil_init() and adds the required functions. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Biurrun	1b4a17094e	h264: remove some disabled code	14 years ago
Diego Biurrun	657ccb5ac7	Eliminate FF_COMMON_FRAME macro. FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied to struct Picture. Replace by an embedded AVFrame structure in struct Picture.	14 years ago
Jason Garrett-Glaser	6a2176aac0	H.264: improve qp_thresh check Eliminate redundant check in filter_mb_fast, consider bit depth in calculating qp_thresh.	14 years ago

Jason Garrett-Glaser	556f8a066c	H.264: template left MB handling Faster H.264 decoding with ALLOW_INTERLACE off.	14 years ago
Jason Garrett-Glaser	3b7ebeb4d5	H.264: faster write_back_* Avoid aliasing, unroll loops, and inline more functions.	14 years ago
Jason Garrett-Glaser	cb5469462d	H.264: faster fill_filter_caches Reduce aliasing problems and unroll mv/ref loop.	14 years ago
Mans Rullgard	add41decd9	Remove return statements following infinite loops without break These statements cannot be reached and are thus not needed. This removes a number of compiler warnings. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Jason Garrett-Glaser	9a0dda8b3a	H.264: disable 2tap qpel with CODEC_FLAG2_FAST and >8-bit 2tap qpel isn't implemented yet for high bit depth, so it just breaks decoding.	14 years ago
Jason Garrett-Glaser	7c9079ab4c	H.264: fix 4:4:4 + deblocking + MBAFF	14 years ago
Jason Garrett-Glaser	3b79f2e2e9	H.264: fix bug in lossless 4:4:4 decoding Coefficient test for i16x16 add_pixels4 assumed luma plane.	14 years ago
Diego Biurrun	6371ce4b0f	h264: Fix assert that failed to compile with -DDEBUG. The assert referenced a variable that no longer exists since 4:4:4 support.	14 years ago
Ronald S. Bultje	ea6331f8bb	h264-mt: fix deadlock in packets with multiple slices (e.g. MP4).	14 years ago
Alex Converse	0c17beba97	h264: drop some ugly casts	14 years ago
Alexander Strange	3803af22d8	h264: Complexify frame num gap shortening code By observation it did not seem to handle prev_frame_num > frame_num. This does not affect any files I have. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Mike Scheutzow	aa15e68721	Fix decoding of mpegts streams with h264 video that does NOT have b frames One of the causes of this bug is that the h264 parser defaults low_delay to 1, but the h264 codec defaults low_delay to 0. Really Ugly. After many hours of looking at this, I'm still not sure how has_b_frames is intended to behave, but to me the implementation appears way more complicated than it ought to be. My patch relies on the encoder to set an optional field in the SPS. This works for libx264 streams, but I'm not sure that all h264 encoders will set it.

Jason Garrett-Glaser	7b442ad918	H.264: fix CODEC_FLAG_GRAY It was broken in 4:4:4, and still did chroma deblocking for no reason in 4:2:0.	14 years ago
Jason Garrett-Glaser	c90b94424c	4:4:4 H.264 decoding support Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.	14 years ago
Jason Garrett-Glaser	504811baea	Roll back 4:4:4 H.264 for now Needs some ARM/PPC asm modifications.	14 years ago

Ronald S. Bultje	4e987f8282	h264: correct border check. When backing up the top-left border, check that the top-left (rather than left) MB indeed does belong to our slice. If it doesn't, backing up has no positive effect but may accidentally interfere with other threads writing in the same space. Fixes occasional one-off effects when enabling slice-MT.	14 years ago
