* Remove all Blackfin architecture optimizationsDiego Biurrun2014-06-02
| | | | | | Blackfin is a painful platform to work with, no test machines are available and the range of multimedia applications is dubious. Thus it only represents a maintenance burden.
* bink: Rename BinkDSPContext member so as not to clash with BlockDSPContextDiego Biurrun2014-06-02

* flacenc: send final extradata in packet side dataAnton Khirnov2014-06-01
|
* lavc: add an option to enable side data-only packets during encodingAnton Khirnov2014-06-01
| | | | | | Some encoders (e.g. flac) need to send side data when there is no more data to be output. This enables them to output a packet with no data in it, only side data.
* libavcodec: set AVFrame colorspace fields on decodingwm42014-06-01

* dsputil: Move SVQ1 encoding specific bits into svq1encDiego Biurrun2014-05-29
|
* svq1enc: Rename SVQ1Context to SVQ1EncContextDiego Biurrun2014-05-29
| | | | This allows making it visible without name clashes.
* ppc: Move vec_unaligned_load macro to util_altivecDiego Biurrun2014-05-28
| | | | This allows reusing it from multiple files.
* flac: make avpriv_flac_parse_block_header() inlineAnton Khirnov2014-05-28
| | | | | | This avoids all the ABI troubles associated with avpriv_. Since this function is very small and does not depend on any tables, making it inline should have no adverse effects.
* flacdec: do not overwrite a channel layout set by the callerAnton Khirnov2014-05-28
| | | | | The channel layout mask for non-standard layouts is typically stored at the container level (as a vorbiscomment tag) for FLAC.
* dsputil: Split off HuffYUV encoding bits into their own contextDiego Biurrun2014-05-27
| | | | Also shorten HuffYUV context member names to avoid clutter.
* dsputil: Split off HuffYUV decoding bits into their own contextDiego Biurrun2014-05-27

* dca: Convert dca_dmixtable to integersNiels Möller2014-05-23
| | | | | | | | Also include zero in the table, eliminating a special case in the decoder. Signed-off-by: Niels Möller <nisse@southpole.se> Signed-off-by: Anton Khirnov <anton@khirnov.net>

* Add transformation matrix API.Vittorio Giovara2014-05-19
| | | | | | | | | | | Add AV_PKT_DATA_DISPLAYMATRIX and AV_FRAME_DATA_DISPLAYMATRIX as stream and frame side data (respectively) to describe a display transformation matrix for linear transformation operations on the decoded video. Add functions to easily extract a rotation angle from a matrix and conversely to setup a matrix for a given rotation angle. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* pthread_frame: simplify the code by using new AVPacket APIAnton Khirnov2014-05-19
| | | | This also handles side data properly.
* avpacket: fix copying side data in av_packet_copy_props()Anton Khirnov2014-05-19
| | | | | | | | Side data count is incremented by by calling av_packet_new_side_data() in the following loop, setting it explicitly results in the resulting value being twice what it should be. CC: libav-stable@libav.org

* lavc: add avcodec_free_context().Anton Khirnov2014-05-18
| | | | | | | | | | | Right now, the caller has to manually manage some allocated AVCodecContext fields, like extradata or subtitle_header. This is fragile and prone to leaks, especially if we want to add more such fields in the future. The only reason for this behaviour is so that the AVStream codec context can be reused for decoding. Such reuse is discouraged anyway, so this commit is the first step to deprecating it.
* lavc: remove the locking code in avcodec_close()Anton Khirnov2014-05-18
| | | | | This function should not modify any global state, so there should be no reason for any locking.
* aarch64: opus NEON iMDCT and FFTJanne Grunau2014-05-15
| | | | | Opus celt decoding 11% faster and the iMDCT over 2.5 times faster on Apple's A7.
* lavc: properly handle subtitle_header in avcodec_copy_context()Anton Khirnov2014-05-15
|
* lavc: preserve the original private data in avcodec_copy_context()Anton Khirnov2014-05-15
| | | | | If a non-NULL codec was passed to avcodec_alloc_context3(), private data will be already allocated in dest.
* lavc: add a native Opus decoder.Anton Khirnov2014-05-15
| | | | | | | | | | | | | Initial implementation by Andrew D'Addesio <modchipv12@gmail.com> during GSoC 2012. Completion by Anton Khirnov <anton@khirnov.net>, sponsored by the Mozilla Corporation. Further contributions by: Christophe Gisquet <christophe.gisquet@gmail.com> Janne Grunau <janne-libav@jannau.net> Luca Barbato <lu_zero@gentoo.org>
* build: handle library dependencies in configureJanne Grunau2014-05-13
| | | | | Instead of setting FFLIBS in each library Makefile configure exports FFLIBS-$library in config.mak.
* aarch64: assembler in clang-3.4 ignores the division by twoJanne Grunau2014-05-13
| | | | Values are positive powers of two, so just replace it with right shift.
* lavc: Add new VDA hwaccelAnton Khirnov2014-05-11
| | | | | | | | | It leverages the new hwaccel 1.2 features: - get_buffer2 is never called - the internal context is automatically initialized/deinitialized Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* vda: use hwaccel private data for internal bitstream bufferAnton Khirnov2014-05-11
|
* lavc: Add hwaccel private data and init/uninit callbacksAnton Khirnov2014-05-11
|
* hwaccel: Support specific frame allocatorsLuca Barbato2014-05-11
| | | | It would reduce the boilerplate code users have to write.
* hwaccel: Rename priv_data_size to frame_priv_data_sizeAnton Khirnov2014-05-11
| | | | This describes more accurately what this field is for.
* lavc: document which parts of AVHWAccel are private.Anton Khirnov2014-05-11
|
* lavc: set AVCodecContext.hwaccel in ff_get_format()Anton Khirnov2014-05-11
| | | | This way each decoder does not have to do the same thing manually.
* lavc: Add an internal wrapper around get_format()Anton Khirnov2014-05-11
| | | | It will be useful in the following commits.
