* vorbisdec: add a flush() functionJustin Ruggles2012-02-24
| | | | clear MDCT overlap buffer and reset previous window mode when seeking
* fraps: release reference buffer on pix_fmt change.Ronald S. Bultje2012-02-24
| | | | | | | | Prevents crash when trying to copy from a non-existing plane in e.g. a RGB32 reference image to a YUV420P target image Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* avcodec: disallow reget_buffer() if pix_fmt changed.Ronald S. Bultje2012-02-24

* kgv1: use avctx->get/release_buffer().Ronald S. Bultje2012-02-24
| | | | | | | Also fixes crashes on corrupt bitstreams. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* mpegaudiodec: Prevent premature clipping of mp3 input buffer.Dale Curtis2012-02-24
| | | | | | | | Instead of clipping extrasize based on EXTRABYTES, clip based on the amount of buffer actually left. Without this fix, there are warbles and other distortions in the test case below. http://kevincennis.com/mix/assets/sounds/1901_voxfx.mp3
* lcl: error out if uncompressed input buffer is smaller than framesize.Ronald S. Bultje2012-02-24
| | | | | | | | This prevents crashes when trying to read beyond the end of the buffer while decoding frame data. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* mjpeg: abort decoding if packet is too large.Ronald S. Bultje2012-02-24

* tiff: Prevent overreads in the type_sizes array.Alex Converse2012-02-23
| | | | | Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* tiff: Make the TIFF_LONG and TIFF_SHORT types unsigned.Alex Converse2012-02-23
| | | | TIFF v6.0 (unimplemented) adds signed equivalents.
* SBR DSP x86: implement SSE sbr_hf_g_filtChristophe GISQUET2012-02-23
| | | | | | | | | | | | | | | Unrolling the main loop to process, instead of 4 elements: - 8: minor gain of 2 cycles (not worth the extra object size) - 2: loss of 8 cycles. Assigning STEP to a register is a loss. Output address (Y) is almost always unaligned. Timings: - C (32/64 bits): 117/109 cycles - SSE: 57 cycles Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* SBR DSP x86: implement SSE sbr_sum_square_sseChristophe GISQUET2012-02-23
| | | | | | | | | | | | | The 32bits targets have been compiled with -mfpmath=sse for proper reference. sbr_sum_square C /32bits: 82c (unrolled)/102c C /64bits: 69c (unrolled)/82c SSE/32bits: 42c SSE/64bits: 31c Use of SSE4.1 dpps to perform the final sum is slower. Not unrolling to perform 8 operations in a loop yields 10 more cycles. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* SBR DSP: use intptr_t for the ixh parameter.Christophe GISQUET2012-02-23

* wavpack: Don't shift minclip/maxclipDerek Buitenhuis2012-02-23
| | | | | | | | | | | Since we are clipping before we shift the values to 16 or 32 bits, we should not shift the min/max clip values to compensate. Fixes 8 and 24 bit lossy decoding. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavc: drop encode() support for video.Anton Khirnov2012-02-23
| | | | | All video encoders have been converted to encode2(), all new encoders should also use only encode2().
* snowenc: switch to encode2().Anton Khirnov2012-02-23
|
* snowenc: don't abuse input picture for storing information.Anton Khirnov2012-02-23
|
* a64multienc: switch to encode2().Anton Khirnov2012-02-23
| | | | We have no decoder, so cannot test if the output is decodable.
* a64multienc: don't write into output buffer when there's no output.Anton Khirnov2012-02-23

|
* lavc: drop libdirac encoder.Anton Khirnov2012-02-23
| | | | | Libschroedinger is the preferred way to encode dirac video now, it produces better output and has a nicer API.

* lcl: don't overwrite input memory.Ronald S. Bultje2012-02-23
| | | | | | | If the PNG filter is enabled, a PNG-style filter will run over the input buffer, writing into the buffer. Therefore, if no zlib compression was used, ensure that we copy into a temporary buffer, otherwise we overwrite user-provided input data.

* libxavs: add an AVClass at the beginning of XavsContext.Anton Khirnov2012-02-23
|
* libxavs: split extradata writing out of encode_nals().Anton Khirnov2012-02-23
| | | | | | | | This is done in preparation for the following patch implementing encode2(). This commit is analogous to 05d699222dd5af4f5775f9890aa825ede05a144f for libx264.

* truemotion2: error out if the huffman tree has no nodes.Ronald S. Bultje2012-02-23
| | | | | | | | This prevents crashers and errors further down when reading nodes in the empty tree. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
