Ronald S. Bultje	64953f67f9	qdm2: clip array indices returned by qdm2_get_vlc(). Prevents subsequent overreads when these numbers are used as indices in arrays.

Mans Rullgard	f5be7958e3	qdm2: fix a dubious pointer cast This reworks a loop to get rid of an ugly pointer cast, fixing errors seen with the PathScale ENZO compiler. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Martin Storsjö	00c3b67b8a	cosmetics: Align codec declarations Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Alex Converse	dac56d9ce0	qdm2: Check data block size for bytes to bits overflow. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	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

Vitor Sessak	984ece7503	qdm2: Use floating point synthesis filter. This avoid needlessly convertion from floating point to fixed point and back. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Mans Rullgard	c4f5c2d6f4	Move some mpegaudio functions to new mpegaudiodsp subsystem This separation allows these functions to be used in a cleaner fashion from other codecs (e.g. qdm2) and simplifies creating optimised versions of them. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	4bac1bbc3b	mpegaudio: add _fixed suffix to some names This adds a _fixed suffix to the fixed-point versions of things with both float and fixed-point variants. This makes it more consistent with other dual-implementation things, e.g. fft. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	1362a291c9	qdm2: include correct header for rdft Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Mans Rullgard	26f548bb59	fft: remove inline wrappers for function pointers This removes the rather pointless wrappers (one not even inline) for calling the fft_calc and related function pointers. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Elio Pettenò	d36beb3f69	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>	14 years ago
Reimar Döffinger	0c1758f018	Return the amount of input data actually used in the qdm2 decoder, allows playback of files where multiple qdm2 packets have been merged. Originally committed as revision 25943 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Baptiste Coudurier	47d2ddca80	Fix qdm2 decoder packet handling to match the api Originally committed as revision 25767 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago

Alex Converse	4c399dc82b	Fix undefined expressions that use multiple calls to get_bits(). Because the order of evaluation of subexpressions is undefined, two get_bits() calls may not be part of the same expression. See also r24902. Originally committed as revision 24906 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	09f6a45dc2	Remove non-existing stray arguments from Doxygen function documentation. Originally committed as revision 23976 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

Måns Rullgård	84dc2d8afa	Remove DECLARE_ALIGNED_{8,16} macros These macros are redundant. All uses are replaced with the generic DECLARE_ALIGNED macro instead. Originally committed as revision 22233 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	c67278098d	Move array specifiers outside DECLARE_ALIGNED() invocations Originally committed as revision 21377 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	9adcccde0c	mpegaudiodec, mpc and qdm2 all use the same mpa_synth window, so make them use the same variable/global storage. Saves 4 kB in .bss. Originally committed as revision 20314 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Benjamin Larsson	fbf4d03a7c	Indent Originally committed as revision 18864 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 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

Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	63cae55d62	Use the new RDFT code in the QDM2 decoder. Originally committed as revision 16865 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Aurelien Jacobs	b250f9c66d	Change semantic of CONFIG_, HAVE_ and ARCH_*. They are now always defined to either 0 or 1. Originally committed as revision 16590 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
