Christophe GISQUET	7e1ce6a6ac	dsputil: remove shift parameter from scalarproduct_int16 There is only one caller, which does not need the shifting. Other use cases are situations where different roundings would be needed. The x86 and neon versions are modified accordingly. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe GISQUET	dabf8dd34a	SBR DSP: unroll sum_square The length is even, so some unrolling can be performed. Timings are for x86: - 32bits: 102c -> 82c - 64bits: 82c -> 69c Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe GISQUET	294c05ce8a	rv34: remove dead code in intra availability check This was an incorrect copy-and-paste to a code not needing the original code. Spotted by Jason in a previous review but forgotten in the commit. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago

Ronald S. Bultje	cc5dd632ce	raw: move buffer size check up. This way, it protects against overreads for 4bpp/2bpp content also. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	f1320dc3be	lpcm: fix sample size calculation for 20bit LCPM. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Diego Biurrun	3c715383ea	vc1: Move init code shared between decoder and parser to common code file. This fixes standalone compilation of the VC-1 parser.	13 years ago
Diego Biurrun	1e9d55e45e	x86: Remove duplicated AVG_3DNOW_OP / AVG_MMX2_OP macros from h264_qpel_mmx.c.	13 years ago
Reimar Döffinger	b5161908e0	SBR DSP: fix SSE code to not use SSE2 instructions. movq from SSE register _to_ memory is an SSE2 instruction. Use the SSE movlps function instead that does the same thing. Signed-off-by: Reimar DÃ¶ffinger <Reimar.Doeffinger@gmx.de> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	6193ff6854	error_resilience: initialize s->block_index[]. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Ronald S. Bultje	c23acbaed4	Don't use ff_cropTbl[] for IDCT. Results of IDCT can by far outreach the range of ff_cropTbl[], leading to overreads and potentially crashes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Martin Storsjö	338978a7c1	libx264: Allow overriding the sliced threads option Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Alex Converse	3574a85ce5	Replace computations of remaining bits with calls to get_bits_left().	13 years ago
Alex Converse	b70feb4053	amrnb/amrwb: Remove get_bits usage. It is used to parse fixed sized fields out of a single octet. The code is simpler without it.	13 years ago
Justin Ruggles	11ac796f7a	dca_parser: parse the sample rate and frame durations	13 years ago
Justin Ruggles	85469f1c9e	libspeexdec: do not set AVCodecContext.frame_size It is not necessary	13 years ago
Justin Ruggles	adbf61ff8a	libopencore-amr: do not set AVCodecContext.frame_size It is not necessary	13 years ago
Justin Ruggles	0efa4073bf	alsdec: do not set AVCodecContext.frame_size It is not necessary	13 years ago
Justin Ruggles	9524cf79df	avcodec: add av_get_audio_frame_duration() function. This is a utility function for the user to get the frame duration based on the codec id, frame size in bytes, and various AVCodecContext parameters.	13 years ago
Justin Ruggles	6699d07480	avcodec: add av_get_exact_bits_per_sample() function This only returns bits per sample when it is exactly correct. That is, the codec contains only raw samples with no frame headers or padding. This applies to basically all PCM codecs and a small subset of ADPCM codecs.	13 years ago
Fabian Greffrath	c9dbac36ad	Fix format string vulnerability detected by -Wformat-security. Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Mans Rullgard	356ee8d7de	x86: clean up ff_dsputil_init_mmx() This splits ff_dsputil_init_mmx() into multiple functions, one for each MMX/SSE level, somewhat simplifying the nested conditions. Signed-off-by: Mans Rullgard <mans@mansr.com> Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Anton Khirnov	44fe77b350	lavc: make codec_is_decoder/encoder() public.	13 years ago
Anton Khirnov	02beb9826b	lavc: deprecate AVCodecContext.sub_id. In most places where it's used, it's as a pointless write-only field. Only rv10 decoder actually reads from it, but it stores some internal version info in it. There is no reason for it to be in a public field.	13 years ago
Kostya Shishkov	4db4b53dc8	proresenc: give user a possibility to alter some encoding parameters This allows user to select quantisation matrix from different profile, stamp frames with custom vendor string and change target bitrate.	13 years ago
Justin Ruggles	1ba08c94f5	vorbisenc: add output buffer overwrite protection	13 years ago
Justin Ruggles	fe78470a8b	libopencore-amrnbenc: fix end-of-stream handling Use CODEC_CAP_DELAY and CODEC_CAP_SMALL_LAST_FRAME to properly pad and flush the encoder at the end of encoding. This is needed in order to have all input samples decoded.	13 years ago
Justin Ruggles	b0350c1c30	ra144enc: fix end-of-stream handling Use CODEC_CAP_DELAY and CODEC_CAP_SMALL_LAST_FRAME to properly pad and flush the encoder at the end of encoding. This is needed in order to have all input samples decoded.	13 years ago

Justin Ruggles	51ddf35c90	wmaenc: fix m/s stereo encoding for the first frame We need to set ms_stereo in encode_init() in order to avoid incorrectly encoding the first frame as non-m/s while flagging it as m/s. Fixes an uncomfortable pop in the left channel at the start of playback. CC:libav-stable@libav.org	13 years ago
Justin Ruggles	8ed7488ea3	wmaenc: return s->block_align instead of recalculating it	13 years ago
Justin Ruggles	5d652e063b	wmaenc: check final frame size against output packet size Currently we have an assert() that prevents the frame from being too large, but it is more user-friendly to give an error message instead of aborting on assert(). This condition is quite unlikely due to the minimum bit rate check in encode_init(), but it is still worth having.	13 years ago
Justin Ruggles	dfc4fdedf8	wmaenc: require a large enough output buffer to prevent overwrites The maximum theoretical frame size is around 17000 bytes. Although in practice it will generally be much smaller, we require a larger buffer just to be safe. CC: libav-stable@libav.org	13 years ago
Justin Ruggles	1ec075cfec	wmaenc: limit allowed sample rate to 48kHz ff_wma_init() allows up to 50kHz, but this generates an exponent band size table that requires 65 bands. The code assumes 25 bands in many places, and using sample rates higher than 48kHz will lead to buffer overwrites. CC:libav-stable@libav.org	13 years ago
Justin Ruggles	c2b8dea182	wmaenc: limit block_align to MAX_CODED_SUPERFRAME_SIZE This is near the theoretical limit for wma frame size and is the most that our decoder can handle. Allowing higher bit rates will just end up padding each frame with empty bytes. Fixes invalid writes for avconv when using very high bit rates. CC:libav-stable@libav.org	13 years ago
Justin Ruggles	0b8b7db01b	mpegaudio_parser: do not ignore information from the first parsed frame Update some demuxing and seeking fate tests.	13 years ago
Michael Niedermayer	6776a8f189	mpegaudio_parser: be less picky about the start position Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
