Justin Ruggles	e4169612a1	apedec: av_fast_malloc() instead of av_realloc() av_realloc() does not guarantee alignment, which is required for DSPContext.bswap_buf().	13 years ago
Justin Ruggles	0759c8eb10	apedec: fix handling of packet sizes that are not a multiple of 4 bytes	13 years ago
Michael Niedermayer	6462d28dcc	apedec: Fix alignment and fate. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
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
Mans Rullgard	644bff6c9b	apedec: fix signed integer overflows This bit manipulation is equivalent but avoids undefined shifts and overflows. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Justin Ruggles	c298b2b8db	apedec: consume the whole packet when copying to the decoder buffer. This avoids artifically consuming a partial packet but ignoring remaining data in subsequent calls.	13 years ago
Justin Ruggles	de157f2118	apedec: do not needlessly copy s->samples to nblocks. also move nblocks to the local scope where it is used.	13 years ago
Justin Ruggles	4315c7d35a	apedec: check output buffer size after calculating actual output size	13 years ago
Justin Ruggles	ad17207b51	apedec: remove unneeded entropy decoder normalization. The decoder already skips data at the end of the packet without this. Also remove 2 APEContext fields that were only used for the end-of-frame normalization.	13 years ago
Justin Ruggles	9a33264478	apedec: assert that s->samples is not negative before trying to decode	13 years ago
Justin Ruggles	0927154d37	apedec: use FFALIGN macro for internal data buffer size	13 years ago
Justin Ruggles	5b8009f4c8	apedec: do not keep incrementing the input data pointer past the end of the buffer during entropy decoding. The pointer address could overflow, which would likely segfault. Instead set the context error flag to indicate that the decoder tried to read past the end of the packet data.	13 years ago
Justin Ruggles	a4c32c9a63	apedec: check for input buffer overflow while reading frame header	13 years ago
Justin Ruggles	fd244ae3a0	apedec: use unsigned int for offset avoids implementation-defined unsigned-to-signed conversion and simplifies the bounds checking.	13 years ago
Justin Ruggles	89ec474a43	apedec: remove pointless increment of 'buf' The variable is not used anymore at that point.	13 years ago
Justin Ruggles	52d4fb2a3d	apedec: set s->currentframeblocks after validating nblocks	13 years ago
Justin Ruggles	2cab578489	apedec: use unsigned int for 'nblocks' and make sure that it's within int range	13 years ago
Justin Ruggles	b7e5145759	apedec: do not set s->samples until after validation. This prevents errors and/or invalid writes in the next decode call due to s->samples still being negative.	13 years ago
Justin Ruggles	11ca8b2d74	apedec: check for data buffer realloc failure	13 years ago
Justin Ruggles	91b71460b5	apedec: return meaningful error values in ape_decode_frame()	13 years ago
Justin Ruggles	c6defb41ef	apedec: correct an error message	13 years ago
Justin Ruggles	da55e0980e	apedec: cosmetics break some excessively long lines and remove space after '*'	13 years ago
Justin Ruggles	f64e0a2f37	apedec: return meaningful error codes from ape_decode_init()	13 years ago
Justin Ruggles	7500781313	apedec: check for filter buffer allocation failure	13 years ago
Justin Ruggles	b9d6b02713	apedec: use memcpy for pseudo-stereo mode	13 years ago
Justin Ruggles	3c25209bd9	apedec: remove unneeded check for zero-size packet. This is already checked by avcodec_decode_audio3().	13 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago
Reinhard Tartler	21a19b7912	doxygen: Prefer member groups over grouping into modules Before this, almost all module groups have been used for grouping functions and fields in structures semantically. This causes them to not appear properly in the file documentation and needlessly clutters up the "Modules" index. Additionally, this commit streamlines some spelling and appearances.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Reinhard Tartler	7ffe76e540	Merge libavcore into libavutil Done to keep ABI compatible. Otherwise this is just silly	14 years ago
Reinhard Tartler	737eb5976f	Merge libavcore into libavutil 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.

Diego Elio Pettenò	e7e2df27f8	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit `d36beb3f69`)	14 years ago

Stefano Sabatini	5d6e4c160a	Replace deprecated symbols SAMPLE_FMT_* with AV_SAMPLE_FMT_*, and enum SampleFormat with AVSampleFormat. Originally committed as revision 25730 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Måns Rullgård	df92772c55	apedec: add flush function Originally committed as revision 23900 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. 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	15 years ago
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	4689ac41e9	16l trocadero: don't forget to free frame data buffer in APE decoder Originally committed as revision 21910 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	b1159ad928	refactor and optimize scalarproduct 29-105% faster apply_filter, 6-90% faster ape decoding on core2 (Any x86 other than core2 probably gets much less, since this is mostly due to ssse3 cachesplit avoidance and I haven't written the full gamut of other cachesplit modes.) 9-123% faster ape decoding on G4. Originally committed as revision 20739 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	d09f65c7ec	1-13% faster apply_filter, 1-3% faster ape decoding on core2 Originally committed as revision 20729 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	1e68cefe54	100l trocadero: call emms_c() after doing decoding with SIMD in APE decoder Originally committed as revision 20727 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Loren Merritt	36373cde20	inline to allow constant propagation 50% faster predictor_update_filter, 1-10% faster ape decoding on core2 Originally committed as revision 20719 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	76267e4e90	Implement missing case for decoding samples with large pivot value in APE decoder. This fixes issue 1555 Originally committed as revision 20560 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	6f24cc0b2a	Monkey's Audio uses subframes too, declare that in its capabilities Originally committed as revision 19883 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	9106a698e7	Rename bitstream.h to get_bits.h. Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist. Originally committed as revision 18351 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
