Anton Khirnov	afa4069e3b	lavc/lavf: remove unnecessary symbols from the symbol version script.	13 years ago
Anton Khirnov	f5f49a66a2	lavc: reorder AVCodec fields. Put all private fields at the end and mark them as such so they can be easily changed/removed. This breaks ABI.	13 years ago
Alex Converse	f372ce119b	mp3dec: Fix a heap-buffer-overflow In some cases, what is left to read from ptr is smaller than EXTRABYTES. Based on a patch by Thierry Foucu <tfoucu@gmail.com>. Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago

Christophe Gisquet	e5c9de2ab7	rv40: x86 SIMD for biweight Provide MMX, SSE2 and SSSE3 versions, with a fast-path when the weights are multiples of 512 (which is often the case when the values round up nicely). *_TIMER report for the 16x16 and 8x8 cases: C: 9015 decicycles in 16, 524257 runs, 31 skips 2656 decicycles in 8, 524271 runs, 17 skips MMX: 4156 decicycles in 16, 262090 runs, 54 skips 1206 decicycles in 8, 262131 runs, 13 skips MMX on fast-path: 2760 decicycles in 16, 524222 runs, 66 skips 995 decicycles in 8, 524252 runs, 36 skips SSE2: 2163 decicycles in 16, 262131 runs, 13 skips 832 decicycles in 8, 262137 runs, 7 skips SSE2 with fast path: 1783 decicycles in 16, 524276 runs, 12 skips 711 decicycles in 8, 524283 runs, 5 skips SSSE3: 2117 decicycles in 16, 262136 runs, 8 skips 814 decicycles in 8, 262143 runs, 1 skips SSSE3 with fast path: 1315 decicycles in 16, 524285 runs, 3 skips 578 decicycles in 8, 524286 runs, 2 skips This means around a 4% speedup for some sequences.

Diego Biurrun	91bafb52ae	x86: Give RV40 init file a more suitable name.	13 years ago
Diego Biurrun	c30b198381	x86: Place mm_flags variable declaration below the appropriate #ifdef. This fixes some unused variable warnings with YASM disabled.	13 years ago
Justin Ruggles	89eea6df28	aacenc: make sure to encode enough frames to cover all input samples. Currently, any samples in the final frame are not decoded because they are only represented by one frame instead of two. So we encode two final frames to cover both the analysis delay and the MDCT delay.	13 years ago
Justin Ruggles	f44005b610	aacenc: only use the number of input samples provided by the user. Fixes handling of CODEC_CAP_SMALL_LAST_FRAME.	13 years ago

Alex Converse	dfa37fe8a3	mpeg12: Pad framerate tab to 16 entries. There are many places where we read an unchecked 4-bit index into it. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind	13 years ago
Michael Niedermayer	a02e8df973	kgv1dec: Increase offsets array size so it is large enough.

Christophe Gisquet	6b03900382	x86 dsputil: provide SSE2/SSSE3 versions of bswap_buf While pshufb allows emulating bswap on XMM registers for SSSE3, more shuffling is needed for SSE2. Alignment is critical, so specific codepaths are provided for this case. For the huffyuv sequence "angels_480-huffyuvcompress.avi": C (using bswap instruction): ~ 55k cycles SSE2: ~ 40k cycles SSSE3 using unaligned loads: ~ 35k cycles SSSE3 using aligned loads: ~ 30k cycles Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Ronald S. Bultje	af79a0c48a	png: add support for bpp>4 to paeth x86 SIMD code. This fixes playback of e.g. RGB48 (bpp=6) content on x86 CPUs. Fixes bug 214.	13 years ago

Ronald S. Bultje	331e7c4cb3	imdct36: mark SSE functions as using all 16 XMM registers. On x86-64, it indeed uses all 16 registers (and on x86-32, this gets clipped to 8). Not marking it properly causes callers of this function to fail randomly because of XMM register clobbering.	13 years ago
Ronald S. Bultje	e92003514d	png: move DSP functions to their own DSP context.	13 years ago

Nathan Caldwell	dc7e7d4dd9	aacenc: Fix a bug where deinterleaved samples were stored in the wrong place. 10l: Forgot to adjust deinterleave for new location of incoming samples in `7946a5a`.

Anton Khirnov	2d9535ad31	avcodec_align_dimensions2: set only 4 linesizes, not AV_NUM_DATA_POINTERS. This function is video-only, so there's no point in setting more linesizes. Fixes stack corruption in avplay.	13 years ago

Martin Storsjö	9a7dc618c5	libavcodec: Don't crash in avcodec_encode_audio if time_base isn't set Earlier, calling avcodec_encode_audio worked fine even if time_base wasn't set. Now it crashes due to trying to scale the output pts to the codec context time base. This affects e.g. VLC. If no time_base is set for audio codecs, set it to the sample rate.
