2012-02-23wavpack: Don't shift minclip/maxclipDerek Buitenhuis
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>

2012-01-15wavpack: fix clipping for 32-bit lossy modeKostya Shishkov
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.
2012-01-02wavpack: fix typos in previous cosmetic clean-up commitJustin Ruggles

2011-12-22Drop ALT_ prefix from BITSTREAM_READER_LE name.Diego Biurrun
The prefix is a historic remnant that probably meant "alternative". Now that the A32 bitstream reader has been dropped it makes no sense anymore.
2011-12-16wavpack: Fix 32-bit clippingDerek Buitenhuis
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>
2011-12-16wavpack: Clip samples after shiftingDerek Buitenhuis
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>
2011-12-04wavpack: Properly clip samples during lossy decodeDerek Buitenhuis
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>
2011-12-03Add avcodec_decode_audio4().Justin Ruggles
Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.

2011-10-07wavpack: Reset internal state on corrupted blocksLaurent Aimar
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>

2011-09-05wavpack: fix wrong return value in wavpack_decode_block()Kostya Shishkov
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>
2011-09-05wavpack: use context reset in appropriate placesKostya Shishkov
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>

2011-07-29lavc: use designated initialisers for all codecs.Anton Khirnov
It's more readable and less prone to breakage.

Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-02-15Merge libavcore into libavutilReinhard Tartler
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.
