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.	14 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.	14 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	14 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>	14 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.	14 years ago

Ronald S. Bultje	20a7d3178f	png: add missing #if HAVE_SSSE3 around function pointer assignment.	14 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.	14 years ago
Ronald S. Bultje	e92003514d	png: move DSP functions to their own DSP context.	14 years ago

Nathan Caldwell	2e626dd513	aacenc: Fix LONG_START windowing. Forgot to add the equivalent amount to the incoming sample pointer as the output pointer. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 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`. This produced incorrect, but surprisingly listenable results. Thanks to Justin Ruggles for the report. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago

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.	14 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.
