* avutil: add AVERROR_UNKNOWNJustin Ruggles2012-02-25
| | | | | Useful to return instead of -1 when the cause of the error is unknown, typically from an external library.
* check for coded_frame allocation failure in several audio encodersJustin Ruggles2012-02-25

* audio encoders: do not set coded_frame->key_frame.Justin Ruggles2012-02-25
| | | | it is already set in avcodec_alloc_frame()

* matroska: don't overwrite string values until read/alloc was succesful.Ronald S. Bultje2012-02-25
| | | | | | | | | | | | This prevents certain tags with a default value assigned to them (as per the EBML syntax elements) from ever being assigned a NULL value. Other parts of the code rely on these being non-NULL (i.e. they don't check for NULL before e.g. using the string in strcmp() or similar), and thus in effect this prevents crashes when reading of such specific tags fails, either because of low memory or because of targeted file corruption.

| | | | 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

| | | | | | | 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

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

* tiff: Make the TIFF_LONG and TIFF_SHORT types unsigned.Alex Converse2012-02-23

* 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

* 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

* 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

* libxvid: switch to encode2().Anton Khirnov2012-02-23

* tiffenc: switch to encode2().Anton Khirnov2012-02-23

* tiffenc: properly forward error codes in encode_frame().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.
