Ronald S. Bultje	5eafc8b466	mt: proper locking around release_buffer calls. This fixes a crash when seeking in some webm files with many threads (e.g. 8).	14 years ago
Jean-Baptiste Kempf	58ef4ecff8	DxVA2: unbreak build after [`657ccb5ac7`] Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Mans Rullgard	1765aacb17	hwaccel: unbreak build Signed-off-by: Mans Rullgard <mans@mansr.com>	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
Anton Mitrofanov	142e76f105	swscale: fix crash with dithering due incorrect offset calculation. ptrdiff_t can be 4 bytes, which leads to the next element being 4-byte aligned and thus at a different offset than intended. Forcing 8-byte alignment forces equal offset of dither16/32 on x86-32 and x86-64. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Anton Khirnov	fdb94444be	matroskadec: fix stupid typo (!= -> ==) Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Biurrun	3e5cce81e7	build: remove duplicates from order-only directory prerequisite list This reduces startup latency for make invocations, which is especially noticeable on systems that are slow or have slow I/O, like Windows.	14 years ago
Mans Rullgard	28e1c97916	build: rework rules for things in the tools dir Declaring tools associated with each library in their respective makefiles allows these tools to easily depend on the correct prerequisites and link against the libs they need. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	b695256edd	configure: fix --cpu=host with gcc 4.6 The output from -v with gcc 4.6 has changed such that the search pattern matches too soon without making it more strict. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	11043d80f6	ARM: use const macro to define constant data in asm Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	39c2a6bf44	bitdepth: simplify FUNC/FUNCC macros Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	710b8df949	dsputil: remove ff_emulated_edge_mc macro used in one place This macro can cause problems in conjunction with the bitdepth template expansion. It was presumably added to keep source compatibility when high bitdepth support was added. However, emulated_edge_mc is a dsputil pointer and should not be called directly, so there is little reason to keep such a macro. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	0f6fc8660e	9/10-bit: simplify clipping macros Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Anton Khirnov	f47ac3c6ca	matroskadec: reindent	14 years ago
Aaron Colwell	31ad14c21e	matroskadec: defer parsing of cues element until we seek. This decreases startup latency. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Anton Khirnov	84626b364b	lavc: add support for codec-specific defaults.	14 years ago
Anton Khirnov	71a861cf40	lavc: make avcodec_alloc_context3 officially public. Deprecate avcodec_alloc_context/2.	14 years ago
Anton Khirnov	18c007ba37	lavc: remove a half-working attempt at different defaults for audio/video codecs. It should be replaced with proper per-codec defaults.	14 years ago
Anton Khirnov	9b83919f44	ac3dec: add a drc_scale private option Deprecate corresponding AVCodecContext option. This is the first test of decoder private options.	14 years ago
Anton Khirnov	a67c061e0f	lavf: add avformat_find_stream_info() It supports passing options to codecs.	14 years ago
Anton Khirnov	0b950fe240	lavc: introduce avcodec_open2() as a replacement for avcodec_open(). Adds support for decoder-private options and makes setting other options simpler.	14 years ago
Jason Garrett-Glaser	7f7dc4fb55	H.264: fix filter_mb_fast with 4:4:4 + 8x8dct	14 years ago
Justin Ruggles	e35c674d13	alsa: limit buffer_size to 32768 frames. In testing, the file output plugin gave a max buffer size of about 20 million frames, which is way more than what is really needed and causes a memory allocation error on my system.	14 years ago
Justin Ruggles	8bfd7f6a47	alsa: fallback to buffer_size/4 for period_size. buffer_size/4 is the value used by aplay. This fixes output to null devices, e.g. writing ALSA output to a file.	14 years ago
Diego Biurrun	4c98976124	doc: replace @pxref by @ref where appropriate	14 years ago
Frank Barchard	f98c9fb27d	mpeg1video: don't abort if thread_count is too high. Instead, just decrease it to a valid value and use that. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Matthew Hoops	84d098d943	segafilm: add support for videos with cri adx adpcm Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Tomas Härdin	99fecc64b0	gxf: Fix 25 fps DV material in GXF being misdetected as 50 fps Set DV packet durations using fields_per_frame. This requires turning gxf_stream_info into the demuxer's context for access to the value in gxf_packet(). Since MPEG-2 seems to work fine this done only for DV. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Diego Biurrun	d8dbe20241	libxvid: Add const qualifier to silence compiler warning. libavcodec/libxvidff.c:752: warning: initialization discards qualifiers from pointer target type	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	99b6d2c065	H.264: use fill_rectangle in CABAC decoding	14 years ago
Jason Garrett-Glaser	298e52c99c	H.264: Remove redundant hl_motion_16/8 code	14 years ago
Jason Garrett-Glaser	ef0c594801	H.264: merge fill_rectangle into P-SKIP MV prediction, to match B-SKIP	14 years ago
Jason Garrett-Glaser	5136ba7c69	H.264: faster P-SKIP decoding Inline the relevant parts of fill_decode_caches into P-SKIP mv prediction to avoid calling the whole thing.	14 years ago
Jason Garrett-Glaser	bbdd52ed34	H.264: av_always_inline some more functions These weren't getting inlined all the time in all gcc versions.	14 years ago
Daniel Kang	c0483d0c7a	H.264: Add x86 assembly for 10-bit H.264 predict functions Mainly ported from 8-bit H.264 predict. Some code ported from x264. LGPL ok by author. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Ronald S. Bultje	5c391a161a	swscale: rename uv_off/uv_off2 to uv_off_px/byte.	14 years ago
Ronald S. Bultje	1ce724ee39	swscale: implement error dithering in planarCopyWrapper. Based on a somewhat similar idea in FFmpeg's swscale.	14 years ago
Ronald S. Bultje	4e3e333a79	swscale: error dithering for 16/9/10-bit to 8-bit. Based on a somewhat similar idea in FFmpeg's swscale copy.	14 years ago
Ronald S. Bultje	7d7bacf0f1	swscale: fix overflow in 16-bit vertical scaling. We operated on 31-bits, but with e.g. lanczos scaling, values can add up to beyond 0x80000000, thus leading to output of zeroes. Drop one bit of precision fixes this.	14 years ago
Ronald S. Bultje	bf2cba4532	swscale: fix crash in 8-bpc bilinear output without alpha. We accessed the alpha array even it wasn't used and didn't exist, hence leading to a NULL pointer segfault.	14 years ago
Ronald S. Bultje	f44d50a94c	swscale: fix 16-bit horizontal scaling underflow. When using e.g. lanczos scaling, values can drop below 0, so they should never be unsigned.	14 years ago
Ronald S. Bultje	42d622fab3	swscale: fix 16-bit scaling when output is 8-bits. We would use the second half of the U plane buffer, rather than the V plane buffer, to output the V plane pixels.	14 years ago
Anton Khirnov	bda168d2b0	mp3enc: write a xing frame containing number of frames in the file	14 years ago
Anton Khirnov	1c6d2b7df0	lavf: update AVStream.nb_frames when muxing.	14 years ago
Anton Khirnov	e98bc78ca1	ffmpeg: remove unused variables from InputStream.	14 years ago
Anton Khirnov	a58db9d283	doc: update ffmpeg -ar and -ac documentation to reflect reality.	14 years ago
Anton Khirnov	20f9f21fd4	ffmpeg: remove pointless if (nb_input_files) It's required to be non-zero since `cc58300e30`	14 years ago
Anton Khirnov	27e91f37f5	ffmpeg: merge input_files_ts_offset into input_files.	14 years ago
Anton Khirnov	9e253c13d0	ffmpeg: merge input_codecs into input_streams. There's no point in keeping them separate.	14 years ago
