* 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
* docs: use -bsf:[vas] instead of -[vas]bsf.John Van Sickle2012-02-24
| | | | | | The latter syntax is now invalid. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* 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
* lavf: move the packet keyframe setting code.Anton Khirnov2012-02-24
| | | | | | | | | | compute_pkt_fields() is for unreliable estimates or guessing. The keyframe information from the parser is (at least in theory) reliable, so it should be used even when the other guessing is disabled with the AVFMT_FLAG_NOFILLIN flag. Therefore, move setting the packet keyframe flag based on parser information from compute_pkt_fields() to read_frame_internal().
* oggenc: free comment header for all codecsJustin Ruggles2012-02-24
| | | | | | fixes a memleak for Vorbis and Theora, where the comment header from avpriv_split_xiph_headers() is replaced by a buffer that must be freed separately.
* 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
| | | | | Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* golomb: use HAVE_BITS_REMAINING() macro to prevent infloop on EOF.Ronald S. Bultje2012-02-24
| | | | | Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

* lavf/output-example: use new audio encoding API correctly.Anton Khirnov2012-02-24
|
* lavf/output-example: more proper usage of the new API.Anton Khirnov2012-02-24
| | | | Passing the codec into avformat_new_stream() is preferred.
* 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>

* swf: check return values for av_get/new_packet().Ronald S. Bultje2012-02-23
| | | | | | | Prevents crashers when using the packet if allocation failed. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* 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>
* rtpenc: Expose the max packet size via an avoptionMartin Storsjö2012-02-23
| | | | | | | | | | This allows opting for a lower MTU than what the AVIOContext indicated, and allows writing into outputs that don't indicate an MTU at all (such as plain files, which is useful for testing). This also allows querying for the MTU via the avoption. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpenc: Move max_packet_size to a context variableMartin Storsjö2012-02-23
| | | | | | This is in preparation for exposing this via an avoption. Signed-off-by: Martin Storsjö <martin@martin.st>

* 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

* a64multienc: switch to encode2().Anton Khirnov2012-02-23
| | | | We have no decoder, so cannot test if the output is decodable.

* 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.

* Remove libpostproc.Diego Biurrun2012-02-23
| | | | | | | | This library does not fit into Libav as a whole and its code is just a maintenance burden. Furthermore it is now available as an external project, which completely obviates any reason to keep it around. URL: http://git.videolan.org/?p=libpostproc.git
* 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.
* swscale: take first/lastline over/underflows into account for MMX.Ronald S. Bultje2012-02-23
| | | | | | | Fixes crashes for extremely large resizes (several 100-fold). Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

* 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

* rtpenc: Allow packetizing H263 according to the old RFC 2190Martin Storsjö2012-02-23
| | | | | | | | | | | | | | | | | | According to newer RFCs, this packetization scheme should only be used for interfacing with legacy systems. Implementing this packetization mode properly requires parsing the full H263 bitstream to find macroblock boundaries (and knowing their macroblock and gob numbers and motion vector predictors). This implementation tries to look for GOB headers (which can be inserted by using -ps <small number>), but if the GOBs aren't small enough to fit into the MTU, the packetizer blindly splits packets at any offset and claims it to be a GOB boundary (by using Mode A from the RFC). While not correct, this seems to work with some receivers. Signed-off-by: Martin Storsjö <martin@martin.st>
