Mans Rullgard	bf5d46d8e6	dca: NEON optimised high freq VQ decoding Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Justin Ruggles	6326afd5e9	avcodec: reject audio packets with NULL data and non-zero size There is no valid reason the user should ever send such packets in the first place, but the documentation for CODEC_CAP_DELAY states that the codec is guaranteed not to get a NULL packet unless that capability is set. That isn't true without preventing this case.	13 years ago
Joakim Plate	dcce09d64b	dxva: Add ability to enable workaround for older ATI cards The workaround needs to be enabled per PCI ID which cannot be detected inside libavcodec. So add a flag to manually enable the alternate behavior. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Kieran Kunhya	d4a544cbc4	latmenc: Set latmBufferFullness to largest value to indicate it is not used Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Justin Ruggles	e562fbd003	adpcm: move codec-specific variable declarations to the sections for the corresponding codecs.	13 years ago
Justin Ruggles	9662539c10	adpcm: check buffer size in Funcom ISS decoder before reading header. Also use the post-header data size to control termination of the main decoding loop.	13 years ago
Justin Ruggles	ba5d2890d7	adpcm: simplify reading of Funcom ISS frame header.	13 years ago
Justin Ruggles	5c9eb4fabb	adpcm: check buffer size in IMA DK4 decoder before reading header. Also use the post-header data size to control termination of the main decoding loop.	13 years ago
Justin Ruggles	a57ea1a87e	adpcm: simplify reading of IMA DK4 frame header.	13 years ago
Justin Ruggles	8114f94ac9	adpcm_ms: clean up reading of predictor coefficients	13 years ago
Justin Ruggles	943f4db552	adpcm_4xm: process planar packets sequentially rather than simultaneously. Also properly clip the right channel step_index.	13 years ago
Justin Ruggles	119974b164	adpcm_ima_wav: process channel-interleaved blocks sequentially rather than simultaneously. Speeds up the ADPCM IMA WAV decoder by 15-20% overall.	13 years ago
Justin Ruggles	7c287b18a0	adpcm: update reference links Add Multimedia Wiki link. Mark dead links with [dead]. Some can still be accessed through archive.org. Update URLs for pages which have moved. Replace duplicated links in adpcmenc.c with a note to see the ADPCM decoder reference documents.	13 years ago
Justin Ruggles	ac94b8bcc6	adpcm: simplify packet size bounds checking in the ADPCM IMA QT decoder. This is easier to understand. It also avoids returning existing samples mixed with new samples when the packet is too small.	13 years ago
Justin Ruggles	de0b586a87	adpcm: simplify and speed up several ADPCM decoders.	13 years ago
Justin Ruggles	5a9ed7c110	adpcm: pretty-print tables	13 years ago
Alex Converse	fcbe421cee	prores: Handle 0 or fewer bits left show_bits() is undefined when the number of bits is less than or equal to zero.	13 years ago
Alex Converse	fe21f78d2b	mpeg probe: check the 2/4-bit synchronization value found after a pack_start_code.	13 years ago
Mans Rullgard	bf00a73ace	dca: clear inactive subbands only once in qmf_32_subbands() Writing zeros to the high entries in the array need only be done once as the cutoff position is constant throughout the loop. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Stefano Sabatini	1ee2014190	vf_unsharp: set default chroma size value to 5x5 The previous default value 0x0 was not good, since it is not even valid. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	998e8519ef	vf_unsharp: fix out-of-buffer read In apply_unsharp(), when y is >= height, prevent out-of-buffer reading from src, read from the last buffer line in src2 instead. The check was implemented in the original unsharp libmpcodecs code and lost in the port. This also fixes output discrepancy between the two filters. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Alex Converse	daf9890811	avconv: Reformat s16 volume adjustment.	13 years ago

Mans Rullgard	a92a1b93b4	dca: use vector_fmac_scalar from dsputil Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	fcca826a63	dsputil: add vector_fmac_scalar() Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Kieran Kunhya	32dfd8ca65	latmenc: Fix private options Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Stefano Sabatini	1c257dc32d	vf_unsharp: store hsub/vsub in the filter context Also drop obfuscating CHROMA_WIDTH/HEIGHT macros. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	e6d17ba426	vf_unsharp: adopt a more natural order of params in apply_unsharp() Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	de7b58da3e	vf_unsharp: rename method "unsharpen" to "apply_unsharp" More consistent with the original libmpcodecs code, and the name "unsharpen" was confusing. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Michael Niedermayer	d33e0c6bc8	vf_scale: apply the same transform to the aspect during init that is applied per frame Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	80de930a78	vf_pad: fix "vsub" variable value computation It was shifting 2 rather than 1, +10l. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	46b29397a6	vf_scale: add a "sar" variable Also create a "dar" alias for the "a" variable, for avoiding possible confusion between dar/sar. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	0ec56d1144	lavfi: fix realloc size computation in avfilter_add_format() Replace sizeof((avff)->formats) with sizeof((avff)->formats) as the size of the array element is given by the pointed element rather than by its pointer. In particular fix computation with the pending patch when sizeof(int64_t) != sizeof(int64_t ). Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	e63e4c99c9	vsrc_color: use internal timebase Avoid timescale conversion, simplify. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	57fa314090	lavfi: fix signature for avfilter_graph_parse() and avfilter_graph_config() Require "void " rather than "AVClass " for the log context type. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	64abd375ec	graphparser: prefer void * over AVClass * for log contexts Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	59cef18c24	avfiltergraph: use meaningful error codes Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Alex Converse	4bb0b31f76	avconv: Initialize return value for codec copy path.	13 years ago
Mans Rullgard	dec4b4705f	fate: use 'run' helper for seek-test This is simpler, and the actual seek-test command is printed with V=1. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	bc3a741fa0	fate: remove seek-mpeg2reuse test The input file for this test is no longer generated. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Michael Niedermayer	77d2ef13a8	Fix memory (re)allocation in matroskadec.c, related to MSVR-11-0080. Whitespace of the patch cleaned up by Aurel Some of the issues have been reported by Steve Manzuik / Microsoft Vulnerability Research (MSVR) Signed-off-by: Michael Niedermayer <michaelni@gmx.at> (cherry picked from commit `956c901c68`) Further suggestions from Kostya <kostya.shishkov@gmail.com> have been implemented by Reinhard Tartler <siretart@tauware.de> Signed-off-by: Reinhard Tartler <siretart@tauware.de>	13 years ago
Alex Converse	a9a033773a	avconv: Fix volume adjustment for non-s16 sample formats	13 years ago
Alex Converse	fe332cf5b9	avconv: Make samples void*. Different sample formats are different sizes.	13 years ago
Alex Converse	af3c06b4db	avconv: Use the size of the decode sample format when allocating the audio samples buffer.	13 years ago
Anton Khirnov	d3c1d37a90	avconv: use different variables for decoded and filtered frame. Makes the code less obfuscated and fixes encoding one video stream to several outputs. Also use avcodec_alloc_frame() instead of allocating AVFrame on stack. Breaks me_threshold in avconv, as motion vectors aren't passed through lavfi. They could be copied manually, but I don't think this misfeature is useful enough to justify ugly hacks.	13 years ago
Anton Khirnov	3ccd15803b	avconv: add support for copying attachments.	13 years ago
Anton Khirnov	c7a63a521b	matroskaenc: write attachments.	13 years ago
Anton Khirnov	98cfe22b5c	matroskadec: export mimetype of attachments as metadata.	13 years ago
Anton Khirnov	becdce99eb	avconv: factorize common code from new_*_stream()	13 years ago
Anton Khirnov	d159060a87	doc/avconv: expand documentation for some options.	13 years ago
