* Add libavresampleJustin Ruggles2012-04-24
| | | | | This is a new library for audio sample format, channel layout, and sample rate conversion.
* FATE: avoid channel mixing in lavf-dv_fmtJustin Ruggles2012-04-24
| | | | | | | This partially reverts acb1730218f1c614dc8ca3ba45d9de1e05059515 which would only have needed to change the checksums if channel mixing had been properly avoided. This changes the output file size reference and the seek test reference back to the previous values.
* avconv: fix a segfault on -c copy with -filter_complex.Anton Khirnov2012-04-24

* isom: Support more DTS codec identifiers.Yusuke Nakamura2012-04-23
| | | | | | DTS LBR identifier ('dtse') is not included since libavcodec doesn't support it yet. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* matroska: Clear prev_pkt between seeks.Dale Curtis2012-04-23
| | | | | | | | | | | The new incremental parser doesn't always clear prev_pkt, however the packet queue is cleared when seeking. Which leads to a use-after-free. Verified using Valgrind. Signed-off-by: Dale Curtis <dalecurtis@chromium.org> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>
* avutil: change default buffer size alignment for sample buffer functionsJustin Ruggles2012-04-23
| | | | | Aligning nb_samples will give both correct plane pointer alignment and enough padding for SIMD-optimized functions.
* audemux: Add a sanity check for the number of channelsMichael Niedermayer2012-04-23
| | | | | | | Fixes a division by 0. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Martin Storsjö <martin@martin.st>
* Remove libdirac decoder.Diego Biurrun2012-04-23
| | | | libschroedinger is the preferred way to decode Dirac video.
* matroska: Add incremental parsing of clusters.Dale Curtis2012-04-22
| | | | | | | | | | | | | | | | | | | | | | Reduces the amount of upfront data required for cluster parsing thus decreasing latency on seek and startup. The change in the seek-lavf_mkv FATE test is due to incremental parsing no longer reading as much data as the old parser and thus not having that additional data to generate index entries based on keyframes. Index entries are added correctly as the file is parsed. All FATE tests pass and Chrome has been using this patch for ~6 months without issue. Currently incremental parsing is not supported for files with SSA tracks since they require merging packets between clusters. In this case the code falls back to non-incremental parsing.

* avconv: fix off by one check in complex_filterLuca Barbato2012-04-22
| | | | nb_input_files is already an invalid index.
* mpegts: Try seeking back even for nonseekable protocolsMartin Storsjö2012-04-23
| | | | | | | | | | | | | | | | | The mpegts demuxer reads 5 KB at startup just for discovering the packet size. Since the default avio buffer size is 32 KB, the seek back to the start will in most cases be within the avio buffer, and will in most cases succeed even if the actual protocol isn't seekable. This makes the demuxer startup faster/with less data when reading data from a non-seekable input, by not skipping the first few KB. If it fails, don't warn if the protocol isn't seekable, making it behave as before in the failure case. Signed-off-by: Martin Storsjö <martin@martin.st>

* ARM: allow runtime masking of CPU featuresMans Rullgard2012-04-22
| | | | | | | This allows masking CPU features with the -cpuflags avconv option which is useful for testing different optimisations without rebuilding. Signed-off-by: Mans Rullgard <mans@mansr.com>
* dsputil: remove unused functionsMans Rullgard2012-04-21
| | | | | | These functions were left unused by the lowres removal. Signed-off-by: Mans Rullgard <mans@mansr.com>

* mov: Take stps entries into consideration also about key_off.Yusuke Nakamura2012-04-21
| | | | | | Splitted files don't start always from a sync sample. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* Remove lowres video decodingMans Rullgard2012-04-21
| | | | | | | This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>
* avcodec: remove AVCodecContext.dsp_maskMans Rullgard2012-04-21
| | | | | | | | This removes all references to AVCodecContext.dsp_mask and marks it for eviction at the next version bump. It has been superseded by av_set_cpu_flag_mask() which, unlike this field, works everywhere. Signed-off-by: Mans Rullgard <mans@mansr.com>
* avconv: fix a segfault when default encoder for a format doesn't exist.Anton Khirnov2012-04-21
| | | | Fail earlier and with a more descriptive error message.
* utvideo: general cosmeticsJan Ekström2012-04-20
| | | | | | | | | General cosmetics, such as keeping lines under 80 characters, fixing a couple of typos (predition -> prediction) and a general style fix that was pointed out by Derek when I was having my sliced multithreading patch in review by him.

* xxan: Remove write-only variable in xan_decode_frame_type0().Diego Biurrun2012-04-20
| | | | libavcodec/xxan.c:293:13: warning: variable ‘corr_end’ set but not used
* ivi_common: Initialize a variable at declaration in ff_ivi_decode_blocks().Diego Biurrun2012-04-20
| | | | This simplifies the code a bit and avoids an uninitialized variable warning.
* avcodec: add a cook parser to get subpacket durationJustin Ruggles2012-04-20
| | | | Fixes jittery video playback of rm files with cook audio.
* FATE: allow lavf tests to alter input parametersJustin Ruggles2012-04-20
| | | | Change some lavf tests to avoid resampling and channel mixing.
* FATE: replace the acodec-pcm_s24daud test with an enc_dec_pcm checksum testJustin Ruggles2012-04-20
| | | | | This avoids resampling and channel mixing by using a source with the correct channel layout and sample rate.
* FATE: replace the acodec-g726 test with 4 new encode/decode testsJustin Ruggles2012-04-20
| | | | | | Avoids resampling and channel mixing. This only tests the behavior with respect to input and output audio rather than also testing changes to the encoder or muxer that do not affect the resulting decoded output.
* FATE: replace current g722 encoding tests with an encode/decode testJustin Ruggles2012-04-20
| | | | | | Avoids resampling and channel mixing. This only tests the behavior with respect to input and output audio rather than also testing changes to the encoder or muxer that do not affect the resulting decoded output.

* avutil: add audio fifo bufferJustin Ruggles2012-04-20
| | | | | The functions operate on the sample level rather than the byte level and work with all audio sample formats.

* FATE: pass the decoded output format and audio source file to enc_dec_pcmJustin Ruggles2012-04-18
| | | | | | | This will allow decoding to md5 and doing a diff comparison to a reference checksum instead of a fuzzy stddev or oneoff comparison. Signed-off-by: Mans Rullgard <mans@mansr.com>
* FATE: specify the input format when decoding in enc_dec_pcm()Justin Ruggles2012-04-18
| | | | | | The output format is not always the same as the file extension, which is sometimes required for correct probing. We can avoid probing by specifying the format since it is already known.
* x86inc: support AVX abstraction for 2-operand instructionsLoren Merritt2012-04-18

* avconv: check for an incompatible changing channel layoutJustin Ruggles2012-04-18
| | | | | | The decoder can change the layout and channel count during decoding, but currently we only validate that the two are compatible when opening the codec. This checks for incompatibilities after each decoded frame.
* avio: make AVIOContext.av_class pointer to constMans Rullgard2012-04-18
| | | | | | | | | | Fix this warning: libavformat/aviobuf.c:663:20: warning: assignment discards qualifiers from pointer target type Although this is a public header, it should remain source and binary compatible. Signed-off-by: Mans Rullgard <mans@mansr.com>

* mpegaudiodec: Do not discard mp_decode_frame() return value.Diego Biurrun2012-04-18
| | | | | This fixes the warning: libavcodec/mpegaudiodec.c:1704:14: warning: variable ‘out_size’ set but not used
* matroska: do not set invalid default duration if frame rate is zeroMans Rullgard2012-04-18
| | | | | | | | | If a video track specifies a zero frame rate (invalid but occurs), this results in a division by zero and subsequent undefined conversion to integer. Setting the default duration from the frame rate only if the latter is greater than zero avoids such problems. Signed-off-by: Mans Rullgard <mans@mansr.com>
* mkv: use av_reduce instead of av_d2q for framerate estimationLuca Barbato2012-04-17
| | | | It avoids some rounding errors.
* mkv: report average framerate as minimal as wellLuca Barbato2012-04-17
| | | | | This is in line with other demuxers and overall seems more correct than assuming codec time base.
* avcodec_string: Favor AVCodecContext.codec over the default codec.Alex Converse2012-04-17
