* lavc decoders: work with refcounted frames.Anton Khirnov2013-03-08
|
* wavpack: decode directly to the user-provided AVFrameJustin Ruggles2013-02-12
|
* lavc: add a wrapper for AVCodecContext.get_buffer().Anton Khirnov2012-12-04
| | | | It will be useful in the upcoming transition to refcounted AVFrames.
* Include libavutil/channel_layout.h instead of libavutil/audioconvert.hJustin Ruggles2012-11-11
| | | | Also reorder some other #include when applicable.
* Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov2012-08-07

* wavpack: Fix an integer overflowDerek Buitenhuis2012-03-02
| | | | | | | | | | Integer Overflow Checker detected an integer overflow while FATE was running. See: http://fate.libav.org/x86_64-linux-ioc/ Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>
* 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>
* wavpack: add needed braces for 2 statements inside an if blockJustin Ruggles2012-02-10

* wavpack: fix clipping for 32-bit lossy modeKostya Shishkov2012-01-15
| | | | | | Reference decoder clips data before shifting it to final range and also forces 32-bit lossy mode to be actually 24-bit lossy mode in order to be able to perform proper clipping.
* wavpack: fix typos in previous cosmetic clean-up commitJustin Ruggles2012-01-02

* wavpack: cosmetics: K&R pretty-printingJustin Ruggles2012-01-02

* wavpack: determine sample_fmt before requesting a bufferHendrik Leppkes2012-01-01
| | | | Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>
* Drop ALT_ prefix from BITSTREAM_READER_LE name.Diego Biurrun2011-12-22
| | | | | The prefix is a historic remnant that probably meant "alternative". Now that the A32 bitstream reader has been dropped it makes no sense anymore.
* wavpack: Fix 32-bit clippingDerek Buitenhuis2011-12-16
| | | | | | | | In the case that (frame_flags & 0x03) == 3, hybrid_maxclip may have had a signed integer overflow. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>
* wavpack: Clip samples after shiftingDerek Buitenhuis2011-12-16
| | | | | | | | It doesn't make much sense to clip pre-shift, nor is it correct for proper decoding. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>
* wavpack: Properly clip samples during lossy decodeDerek Buitenhuis2011-12-03
| | | | | | | | When decoding lossy WavPack samples, they are supposed to be clipped, in order to be decoded correctly. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* Add avcodec_decode_audio4().Justin Ruggles2011-12-02
| | | | | | Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.
* wavpack: calculate bpp using av_get_bytes_per_sample()Justin Ruggles2011-10-23
|
* wavpack: Reset internal state on corrupted blocksLaurent Aimar2011-10-07
| | | | | | | | wavpack_decode_block() supposes that it is called back with the exact same buffer unless it has returned with an error. With multi-channels files, wavpack_decode_frame() was breaking this assumption. Signed-off-by: Janne Grunau <janne-libav@jannau.net>

* wavpack: fix wrong return value in wavpack_decode_block()Kostya Shishkov2011-09-05
| | | | | | | | This function should return number of samples decoded, not number of bytes decoded. Spotted by Uoti Urpala. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* wavpack: use context reset in appropriate placesKostya Shishkov2011-09-05
| | | | | | | | This fixes improper flushing in the cases when the same frame is decoded in several iterations (for being too large to fit into output buffer) and flush is called mid-decoding and it also resets context in case of decoding errors. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* WavPack decoder: implement flush functionKostya Shishkov2011-08-21
| | | | Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* lavc: use designated initialisers for all codecs.Anton Khirnov2011-07-29
| | | | It's more readable and less prone to breakage.
* Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-19

* Merge libavcore into libavutilReinhard Tartler2011-02-15
| | | | | | | | | | | | It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-26

| | | | | | | | Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
