* build: Skip compiling xvmc.h under the correct condition.Diego Biurrun2012-03-09

* aacdec: Fix SCE parity check.Michael Niedermayer2012-03-09
| | | | | | | | | An unpaired SCE preceding a CPE only makes sense for front SCEs preceding the first CPE. Split from FFmpeg commit a8d67efa53dae1d14614e3a7bd4e77e4eab066ab Signed-off-by: Alex Converse <alex.converse@gmail.com>
* aacdec: Fix out of array writes (stack).Michael Niedermayer2012-03-09
| | | | | | | | | | | | 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.

* ttadec: unbreak playback of matroska filesPaul B Mahol2012-03-08
| | | | | | | | 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>
* vorbisdec: avoid invalid memory accessAaron Colwell2012-03-08
| | | | | | | | | 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>
* huffyuv: add padding to classic (v1) huffman tables.Ronald S. Bultje2012-03-08
| | | | | | | | | | 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
* png: convert to bytestream2 API.Ronald S. Bultje2012-03-08
| | | | | | | Protects against overreads in the input buffer. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

* avs: fix infinite loop on end-of-stream.Ronald S. Bultje2012-03-07
| | | | | | | | | 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
* tiffdec: Prevent illegal memory access caused by recycled pointers.Alex Converse2012-03-07
| | | | | Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

* sbrdsp.asm: convert all instructions to float/SSE ones.Reimar Döffinger2012-03-07
| | | | | | | | | | | 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. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* Revert "AAC SBR: group some writes."Ronald S. Bultje2012-03-07
| | | | | This reverts commit ba36f14e5d34bcca6ecf77ba1c7512d1b51a9740. It broke decoding on x86-32 on some systems.

* dca: don't use av_clip_uintp2().Ronald S. Bultje2012-03-07
| | | | | The argument is not a literal, thus causing the ARM v6 or later builds to break.

* dsputil: remove shift parameter from scalarproduct_int16Christophe GISQUET2012-03-07
| | | | | | | | | 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>
* SBR DSP: unroll sum_squareChristophe GISQUET2012-03-07
| | | | | | | | 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>
* rv34: remove dead code in intra availability checkChristophe GISQUET2012-03-07
| | | | | | | 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>

| | | | | | | | Results of IDCT can by far outreach the range of ff_cropTbl[], leading to overreads and potentially crashes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

* amrnb/amrwb: Remove get_bits usage.Alex Converse2012-03-05
| | | | | It is used to parse fixed sized fields out of a single octet. The code is simpler without it.

* avcodec: add av_get_audio_frame_duration() function.Justin Ruggles2012-03-05
| | | | | 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.
* avcodec: add av_get_exact_bits_per_sample() functionJustin Ruggles2012-03-05
| | | | | | 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.
