Michael Niedermayer	9729f140ae	diracdec: Fix integer overflow leading to out of global array read. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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

Reimar Döffinger	2ab5feafe1	huffman: use a simple assignment instead of FFSWAP. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Reimar Döffinger	6166bf3cbe	Deobfuscate ff_huff_build_tree. I have no idea what the idea was behind the original code, but the new code is equivalent to it. In that loop that places the new node nodes[j] contains always the data of the new node (since the steps are always in order: FFSWAP copies node[j] to node[j-1], j is decremented). Thus nodes[j].no == i and nodes[j].sym == HNODE. make fate still passes and contains VP6 samples which use FF_HUFFMAN_FLAG_HNODE_FIRST.

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

Mans Rullgard	3715d841a6	Fix non-C89 declarations in for loops Some compilers still do not support this syntax. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Reimar Döffinger	f9eb622944	Fix offset validity checks. Offsets are relative to the end of the header, not the start of the buffer, thus the buffer size needs to be subtracted. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Reimar Döffinger	cd3ced1bb9	fraps: frame threading support. Codec is too simple to gain much from it at lower resolutions, but should help at very high resolutions, particularly for v3 and v5 where a not too optimized pseudo-YUV to RGB is done in the codec. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Reimar Döffinger	0efdb942a6	fraps: Deduplicate some code. Also moves it before the get_buffer call so that most error exits happen before it. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago

Carl Eugen Hoyos	a915618a29	Improve decoding quality for lossy wavpack. This reverts `e6e7bfc1` and `365e1ec2`. The code may be incorrect both before and after the revert, but we do not have any samples that were fixed by the original commits. Fixes ticket #871.	13 years ago
Reimar Döffinger	7fabef1f01	fraps: optimize pseudo-YUV to RGB conversion. With gcc 4.6 this part of the code is ca. 4x faster, resulting in an overall speedup of around 5% for fate-fraps-v5 sample. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	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
