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
Diego Biurrun	a92be9b856	Replace memset(0) by zero initializations. Also remove one pointless zero initialization in rangecoder.c.	13 years ago
Ronald S. Bultje	262196445c	wmavoice: fix stack overread. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Diego Biurrun	cfac648e6a	doxygen: Remove documentation for non-existing parameters; misc small fixes.	13 years ago
Ronald S. Bultje	8cfbbd928c	get_bits: introduce safe bitreading to prevent overreads. When turned on, H264/CAVLC gets ~15% (CVPCMNL1_SVA_C.264) slower for ultra-high-bitrate files, or ~2.5% (CVFI1_SVA_C.264) for lower-bitrate files. Other codecs are affected to a lesser extent because they are less optimized; e.g., VC-1 slows down by less than 1% (all on x86). The patch generated 3 extra instructions (cmp, cmovae and mov) per call to get_bits(). The performance penalty on ARM is within the error margin for most files, up to 4% in extreme cases such as CVPCMNL1_SVA_C.264. Based on work (for GCI) by Aneesh Dogra <lionaneesh@gmail.com>, and inspired by patch in Chromium by Chris Evans <cevans@chromium.org>.	13 years ago
Diego Biurrun	da9cea77e3	Fix a bunch of common typos.	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
Alex Converse	f11b0e9543	wmavoice: Make format string match variable type.	13 years ago
Justin Ruggles	813907d424	wmavoice: move output buffer size check to synth_superframe(). this allows for checking against the actual output size instead of max size.	13 years ago
Justin Ruggles	d064076570	wmavoice: only set data_size to 0 when necessary	13 years ago
Anton Khirnov	9f51c682ee	lavc: use avpriv_ prefix for ff_copy_bits and align_put_bits. They are used in lavf.	13 years ago
Mans Rullgard	ba3f07d061	wmavoice: fix a signed overflow Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Laurent Aimar	d99427cb8b	wmavoice: Check for corrupted extra data Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Laurent Aimar	1c1449b548	wmavoice: Check for out of bound writes Signed-off-by: Janne Grunau <janne-libav@jannau.net>	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
Alex Converse	869303bebd	wmavoice: Use proper size in memeset(). sizeof(array_functrion_argument) gives the size of the pointer type not the size of the array to which it points.	14 years ago
Vitor Sessak	9d35fa520e	Add AVX FFT implementation. Signed-off-by: Reinhard Tartler <siretart@tauware.de>	14 years ago
Diego Biurrun	6001dad6e2	Replace more FFmpeg references by Libav.	14 years ago
Mans Rullgard	0aded9484d	Move dct and rdft definitions to separate files This leaves fft.h with only the core FFT and MDCT definitions thus making it more managable. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	4538729afe	Move sine windows to a separate file These windows do not really belong in fft/mdct files and were easily confused with the similarly named tables used by 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
Ronald S. Bultje	18f1add31c	Fix typo. Originally committed as revision 26099 to svn://svn.ffmpeg.org/ffmpeg/trunk	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
Ronald S. Bultje	af0a61cc40	Fix buffer overrun if idx is negative (it can be down to -23>>4), by prepending two padding zeroes before it. Should fix fate failures on openBSD and crashes on MacOSX (that I cannot reproduce). Originally committed as revision 24750 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Axel Holzinger	0b2c75cb68	Rename pow variable to pwr. Patch by Axel Holzinger <aholzinger gmx de>. Originally committed as revision 24508 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	862be470f3	Use correct length modifier for size comparison in printf expression, fixes: libavcodec/wmavoice.c:1906: warning: format `%lu' expects type `long unsigned int', but argument 5 has type `unsigned int' approved by Ronald and Mans on IRC Originally committed as revision 24218 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	ad32966cf9	Fix two doxy warnings. Originally committed as revision 24109 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Eli Friedman	25fe863062	Silense one warning: "passing argument 1 of ‘av_memcpy_backptr’ from incompatible pointer type" Patch by Eli Friedman, eli D friedman A gmail Originally committed as revision 23895 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	1302ccc1a7	Another buffer overflow, fixes issue1758. Originally committed as revision 23011 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	593a861470	Fix buffer overrun (or, well, actually a typo, 80 should be 0x80...). Partially fixes issue 1758. Originally committed as revision 23005 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	9a32573b49	WMAVoice postfilter. Originally committed as revision 22938 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	b1078e9fe6	Move clipping of audio samples (for those codecs outputting float) from decoder to the audio conversion routines. Originally committed as revision 22937 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
Benoit Fouet	32e543f866	Replace @returns by @return . Originally committed as revision 22729 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
