Vittorio Giovara	059a934806	lavc: Consistently prefix input buffer defines Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Vittorio Giovara	def97856de	lavc: AV-prefix all codec capabilities Express bitfields more simply. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Anton Khirnov	23a211cbba	lavc: change all decoders to behave consistently with AV_EF_CRCCHECK. Just crccheck prints a warning, crccheck+explode returns an error. Also document this behavior.	11 years ago
Diego Biurrun	b2bed9325d	cosmetics: Group .name and .long_name together in codec/format declarations	11 years ago
Anton Khirnov	89806691b1	wavpack: check that all the channels were coded.	12 years ago
Anton Khirnov	eae1b8451a	wavpack: check that there aren't too many blocks per packet	12 years ago
Anton Khirnov	7d039e70a5	wavpack: extract channel information from the bitstream This way we don't require the caller to parse the block header. It also allows the channel configuration to change mid-stream.	12 years ago
Anton Khirnov	78f75b6fa4	wavpack: extract sample rate from the bitstream This way we don't require the caller to parse the block header. It also allows the sample rate to change mid-stream.	12 years ago
Anton Khirnov	9b6f47c448	matroskadec: export full wavpack blocks. This allows us to get rid of demuxer-specific hacks in the decoder and will allow streamcopy from matroska once we have a wavpack muxer.	12 years ago
Anton Khirnov	5074f4545c	wavpack demuxer: export full wavpack blocks. Currently the demuxer shaves the blocks and exports only the information that is useful to the decoder. Exporting the blocks just as they are stored is simpler to understand and will make remuxing wavpack easier.	12 years ago
Anton Khirnov	72dee5f40b	wavpack: don't set sample format in init. We don't know whether it will be float until we look at the data.	12 years ago
Anton Khirnov	35596bd4f4	wavpack: remove a useless parameter from wavpack_decode_block(). The decoder always returns output if an error does not occur.	12 years ago
Anton Khirnov	d1bec4be22	wavpack: return an error on 0-sized blocks Such blocks are not valid.	12 years ago
Anton Khirnov	1d177200ce	wavpack: remove a useless check. Number of samples in the first block is checked to be strictly positive earlier in wavpack_decode_frame() and number of samples in all the other blocks is checked to be equal to the first one.	12 years ago
Anton Khirnov	0f3a0b24dd	wavpack: add an error message to a failure.	12 years ago
Anton Khirnov	474fb0c9d9	wavpack: return 0 instead of samples count from decoding functions The caller never cares about the number of decoded samples, so this only confuses the reader.	12 years ago
Anton Khirnov	528daa3990	wavpack: switch to planar output This simplifies the code and makes it faster.	12 years ago
Anton Khirnov	a7ec3a9a4e	wavpack: drop redundant if/else blocks	12 years ago
Anton Khirnov	7b44c99180	wavpack: remove the subframes codec cap The decoder always consumes full packets.	12 years ago
Luca Barbato	fd06291239	wavpack: check packet size early Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	12 years ago
Luca Barbato	3f0b6d7a62	wavpack: use bytestream2 in wavpack_decode_block Prevent most out of buffer reads. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	12 years ago
Luca Barbato	ed50673066	wavpack: validate samples size parsed in wavpack_decode_block Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	12 years ago
Luca Barbato	8c34558131	wavpack: return meaningful errors And forward those that were already meaningful.	12 years ago
Luca Barbato	0f689a3d97	wavpack: K&R formatting cosmetics Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	12 years ago
Justin Ruggles	9873d71f31	wavpack: decode directly to the user-provided AVFrame	12 years ago
Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	12 years ago
Justin Ruggles	a903f8f087	Include libavutil/channel_layout.h instead of libavutil/audioconvert.h Also reorder some other #include when applicable.	12 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	13 years ago
Hendrik Leppkes	37c6ad2345	wavpack: set bits_per_raw_sample for S32 samples to properly identify 24-bit Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	13 years ago
Derek Buitenhuis	f604eab30a	wavpack: Fix an integer overflow 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>	13 years ago
Derek Buitenhuis	480b133e6f	wavpack: Don't shift minclip/maxclip 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>	13 years ago
Justin Ruggles	9d7cee50aa	wavpack: add needed braces for 2 statements inside an if block	13 years ago
Paul B Mahol	c388558d31	wavpack: allow user to disable CRC checking Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Kostya Shishkov	e6e7bfc11e	wavpack: fix clipping for 32-bit lossy mode 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.	13 years ago
Justin Ruggles	3a1867deac	wavpack: fix typos in previous cosmetic clean-up commit	13 years ago
Justin Ruggles	513c238fa9	wavpack: cosmetics: K&R pretty-printing	13 years ago
Hendrik Leppkes	14165fe125	wavpack: determine sample_fmt before requesting a buffer Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Diego Biurrun	aaf47bcde7	Drop ALT_ prefix from BITSTREAM_READER_LE name. The prefix is a historic remnant that probably meant "alternative". Now that the A32 bitstream reader has been dropped it makes no sense anymore.	13 years ago
Derek Buitenhuis	bb9747c8ee	wavpack: Fix 32-bit clipping 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>	13 years ago
Derek Buitenhuis	365e1ec26d	wavpack: Clip samples after shifting 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>	13 years ago
Derek Buitenhuis	a548b6cbfc	wavpack: Properly clip samples during lossy decode 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>	13 years ago
Justin Ruggles	0eea212943	Add avcodec_decode_audio4(). Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.	13 years ago
Justin Ruggles	d2604f9260	wavpack: calculate bpp using av_get_bytes_per_sample()	13 years ago
Laurent Aimar	2c6cf13940	wavpack: Reset internal state on corrupted blocks 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>	13 years ago
Laurent Aimar	8bfea4ab4e	Fixed segfault with wavpack decoder on corrupted decorrelation terms sub-blocks. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Alex Converse	dba2b63a98	wavpack: Check error codes rather than working around error conditions.	13 years ago
Laurent Aimar	55354b7de2	Fixed invalid access in wavpack decoder on corrupted bitstream. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Laurent Aimar	0aedab0340	Fixed invalid writes in wavpack decoder on corrupted bitstreams. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Laurent Aimar	beefafda63	Fixed invalid access in wavpack decoder on corrupted extra bits sub-blocks. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
