Kostya Shishkov	7f92db14f9	g723_1: save/restore excitation with offset to store LPC history The same buffer with saved data is used later in LPC reconstruction, so it should have some head space for LPC history.	13 years ago
Sean McGovern	3680b24351	wmapro: prevent division by zero when sample rate is unspecified This fixes Bugzilla #327: Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	13 years ago

Ronald S. Bultje	c728518b3c	x86: fft: fix imdct_half() for AVX Some calculations were changed in `b6a3849` to use mmsize, which was not correct for the AVX version, which uses INIT_YMM and therefore has mmsize == 32. Fixes Bug 341. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Alex Rønne Petersen	150adea6da	rtmppkt: Add missing libavcodec/bytestream.h include. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	13 years ago
Jordi Ortiz	50468f93e3	rtmp: add functions for reading AMF values Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	13 years ago
Mans Rullgard	cfb1091898	vc1dec: remove useless #include simple_idct.h Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	af500c08bb	dct-test: always link with aandcttab.o This allows building dct-test even if aandcttab.o is not pulled in by any enabled codec. The DCT with which these tables are used does not use them directly, so building it without the tables is possible. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	cf5781fad0	vp8: pack struct VP8ThreadData more efficiently Reordering the members in this struct reduces the holes required to maintain alignment. With this order, the only remaining, and unavoidable, hole is 3 bytes following left_nnz. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	ec7c501ed5	x86: remove libmpeg2 mmx(ext) idct functions These functions are not faster than other mmx implementations on any hardware I have been able to test on, and they are horribly inaccurate. There is thus no reason to ever use them. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Derek Buitenhuis	a675d73d57	eamad: Use dsputils instead of a custom bswap16_buf Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	13 years ago
Derek Buitenhuis	45eaac02cb	Canopus Lossless decoder At the moment it only does BGR24, but I plan to add the rest after. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	13 years ago
Diego Biurrun	19cf7163c1	dca: Switch dca_sample_rates to avpriv_ prefix; it is used across libs	13 years ago
Mans Rullgard	faa788227f	ARM: use =const syntax instead of explicit literal pools Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	998170913c	ARM: use standard syntax for all LDRD/STRD instructions The standard syntax requires two destination registers for LDRD/STRD instructions. Some versions of the GNU assembler allow using only one with the second implicit, others are more strict. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Ronald S. Bultje	b6a3849adb	fft: port FFT/IMDCT 3dnow functions to yasm, and disable on x86-64. 64-bit CPUs always have SSE available, thus there is no need to compile in the 3dnow functions. This results in smaller binaries.	13 years ago
Ronald S. Bultje	ddbe71b44f	dct-test: allow to compile without HAVE_INLINE_ASM.	13 years ago
Ronald S. Bultje	53dfaedc01	x86/dsputilenc: bury inline asm under HAVE_INLINE_ASM.	13 years ago
Diego Biurrun	9e4bca16f8	dca: Move tables used outside of dcadec.c to a separate file.	13 years ago
Diego Biurrun	13a79cf84e	dca: Rename dca.c ---> dcadec.c This will allow adding dca.c with tables used from other files.	13 years ago

Samuel Pitoiset	9c9c21eaa1	rtmp: do not warn about receiving metadata packets They are managed in get_packet() Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	13 years ago
Diego Biurrun	8728b381cb	x86: h264dsp: Adjust YASM #ifdefs This fixes compilation with YASM disabled.	13 years ago
Diego Biurrun	d1505db067	x86: yadif: Mark mmxext optimizations as such The yadif mmx optimizations contain the pmaxsw and pmaxub mmxext instructions, causing sigills on CPUs that do not support mmxext.	13 years ago
Ronald S. Bultje	b829b4ce29	h264: convert loop filter strength dsp function to yasm. This completes the conversion of h264dsp to yasm; note that h264 also uses some dsputil functions, most notably qpel. Performance-wise, the yasm-version is ~10 cycles faster (182->172) on x86-64, and ~8 cycles faster (201->193) on x86-32.	13 years ago

Mans Rullgard	f3eb008343	eamad/eatgq/eatqi: call special EA IDCT directly These decoders use a special non-MPEG2 IDCT. Call it directly instead of going through dsputil. There is never any reason to use a regular IDCT with these decoders or to use the EA IDCT with other codecs. This also fixes the bizarre situation of eamad and eatqi decoding incorrectly if eatgq is disabled. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	591766a3a9	eamad: remove use of MpegEncContext There is no sense in pulling in this monster struct just for a handful of fields. The code does not call any functions expecting an MpegEncContext. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	87cf481aa8	mpegvideo: remove unnecessary inclusions of faandct.h Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Justin Ruggles	be51e589cd	af_asyncts: avoid overflow in out_size with large delta values	13 years ago
Justin Ruggles	70d71b5801	af_asyncts: add first_pts option This allows for padding/trimming at the start of stream. By default, no assumption is made about the first frame's expected pts, so no padding or trimming is done.	13 years ago
Luca Barbato	41f43202cf	flvdec: remove spurious use of stream id We match streams by codec id now.	13 years ago
Anton Khirnov	aba232cfa9	lavf: deprecate r_frame_rate. According to its description, it is supposed to be the LCM of all the frame durations. The usability of such a thing is vanishingly small, especially since we cannot determine it with any amount of reliability. Therefore get rid of it after the next bump. Replace it with the average framerate where it makes sense. FATE results for the wtv and xmv demux tests change. In the wtv case this is caused by the file being corrupted (or possibly badly cut) and containing invalid timestamps. This results in lavf estimating the framerate wrong and making up wrong frame durations. In the xmv case the file contains pts jumps, so again the estimated framerate is far from anything sane and lavf again makes up different frame durations. In some other tests lavf starts making up frame durations from different frame.	13 years ago
Anton Khirnov	f66eeff1c8	lavf: round estimated average fps to a "standard" fps.	13 years ago
Anton Khirnov	fe1c1198e6	lavf: use dts difference instead of AVPacket.duration in find_stream_info() AVPacket.duration is mostly made up and thus completely useless, this is especially true for video streams. Therefore use dts difference for framerate estimation and the max_analyze_duration check. The asyncts test now needs -analyzeduration, because the default is 5 seconds and the audio stream in the sample appears at ~10 seconds.	13 years ago
