Diego Biurrun	eab6968f24	build: Skip compiling xvmc.h under the correct condition.	13 years ago
Michael Niedermayer	744dd1d356	aacdec: Fix SCE parity check. An unpaired SCE preceding a CPE only makes sense for front SCEs preceding the first CPE. Split from FFmpeg commit `a8d67efa53` Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago
Michael Niedermayer	d53fe096e4	aacdec: Fix out of array writes (stack). Set the element to channel vector (e2c_vec) size to be the maximum number of aac channel elements. This makes it slightly larger than it needs to be because CCEs are never mapped to output channel locations. Also add a check that all input tags (legal or not) will fit.

Paul B Mahol	ea1d64ab10	ttadec: unbreak playback of matroska files Matroska demuxer needs to recreate tta header, so just display crc error without aborting. Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Aaron Colwell	12623a8026	vorbisdec: avoid invalid memory access This fixes some invalid memory access caused later in the function by res_chan[] not being set for all channels. This happens when a channel doesn't appear a submap. This change simply returns a decoder error when this situation is detected. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	4ffe5e2aa5	huffyuv: add padding to classic (v1) huffman tables. We slightly overread the input buffer, so we require padding at the end of the buffer, as is documented in the get_bits API. Without padding, we'll read uninitialized data or beyond the end of the .rodata, which may crash. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	4c25269ced	png: convert to bytestream2 API. Protects against overreads in the input buffer. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Kostya Shishkov	681e726865	dca: include libavutil/mathematics.h for possibly missing M_SQRT1_2	13 years ago
Ronald S. Bultje	83f15a1228	avs: fix infinite loop on end-of-stream. The codec would keep returning the last decoded frame if the stream contains B-frames, since it wouldn't clear that frame from the list of frames to be returned to the user. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Alex Converse	fd0be63049	tiffdec: Prevent illegal memory access caused by recycled pointers. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Reimar Döffinger	6eda85e15b	sbrdsp.asm: convert all instructions to float/SSE ones. Since the values are floats, using the float operations makes sense, improves performance on some CPUs and makes the code SSE compatible instead of needing SSE2. Based on suggestion by Jason.

Ronald S. Bultje	6e2821160b	Revert "AAC SBR: group some writes." This reverts commit `ba36f14e5d`. It broke decoding on x86-32 on some systems.	13 years ago
Ronald S. Bultje	37cc8600d0	cook: extend channel uncoupling tables so the full bit range is covered. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Ronald S. Bultje	93b53ffb1a	dca: don't use av_clip_uintp2(). The argument is not a literal, thus causing the ARM v6 or later builds to break.	13 years ago
Ronald S. Bultje	626964a4c4	wmall: fix build with -DDEBUG enabled.	13 years ago

Christophe Gisquet	ba36f14e5d	AAC SBR: group some writes. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe GISQUET	7e1ce6a6ac	dsputil: remove shift parameter from scalarproduct_int16 There is only one caller, which does not need the shifting. Other use cases are situations where different roundings would be needed. The x86 and neon versions are modified accordingly. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe GISQUET	dabf8dd34a	SBR DSP: unroll sum_square The length is even, so some unrolling can be performed. Timings are for x86: - 32bits: 102c -> 82c - 64bits: 82c -> 69c Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe GISQUET	294c05ce8a	rv34: remove dead code in intra availability check This was an incorrect copy-and-paste to a code not needing the original code. Spotted by Jason in a previous review but forgotten in the commit. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago

Justin Ruggles	9524cf79df	avcodec: add av_get_audio_frame_duration() function. This is a utility function for the user to get the frame duration based on the codec id, frame size in bytes, and various AVCodecContext parameters.	13 years ago
Justin Ruggles	6699d07480	avcodec: add av_get_exact_bits_per_sample() function This only returns bits per sample when it is exactly correct. That is, the codec contains only raw samples with no frame headers or padding. This applies to basically all PCM codecs and a small subset of ADPCM codecs.	13 years ago
