* jvdec: unbreak video decodingPaul B Mahol2012-03-14
| | | | | | | | The safe bitstream reader broke it since the buffer size was specified in bytes instead of bits. Signed-off-by: Janne Grunau <janne-libav@jannau.net> CC: libav-stable@libav.org

* libx264: add 'stats' private option for setting 2pass stats filename.Anton Khirnov2012-03-13
| | | | | | | x264 always opens the file itself with fopen, so we cannot use the standard lavc stats mechanism. CC: libav-stable@libav.org

* h264: improve parsing of broken AVC SPSMichael Niedermayer2012-03-13
| | | | | | | | | | | | Parsing the entire NAL as SPS fixes decoding of some AVC bitstreams with broken escaping. Since the size of the NAL unit is known and checked against the buffer end we can parse it entirely without buffer overreads. Fixes playback of http://streams.videolan.org/streams/mp4/Mr_MrsSmith-h264_aac.mp4 Signed-off-by: Janne Grunau <janne-libav@jannau.net>

* Revert "h264: clear trailing bits in partially parsed NAL units"Janne Grunau2012-03-12
| | | | | | | | | | | | | This reverts commit 729ebb2f185244b0ff06d48edbbbbb02ceb4ed4e. There was an off-by-one error in the bit mask calculation clearing actually the last valid bit and causing http://bugzilla.libav.org/show_bug.cgi?id=227 The broken sample (Mr_MrsSmith-h264_aac.mp4) the commit was fixing does not work after correcting the off-by-one error.

* remove iwmmxt optimizationsJanne Grunau2012-03-12
| | | | | | The were broken since August of 2010 without anyone noticing until three weeks ago. Nobody cares about it anymore and hopefully Marvell will support NEON like in the PXA978 from now on.

* mpc: pad mpc_CC/SCF[] tables to allow for negative indices.Ronald S. Bultje2012-03-10
| | | | | | | | MPC8 allows indices of mpc_CC up to -1, and mpc_SCF up to -6, thus pad the tables by that much on the left end. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

* 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

* 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

* 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

* 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.
