Justin Ruggles	e951b6d94c	vorbisdec: cosmetics: rename variable avccontext to avctx This is consistent with the rest of libavcodec.	12 years ago
Diego Biurrun	b2d688ea9f	configure: Identify icc compiler with a less ambiguous pattern	12 years ago
Diego Biurrun	b58b00aeca	configure: Separate "ln" command line arguments This is more compatible and not more complicated.	12 years ago
Luca Barbato	23bd9ef4b2	vorbisdec: Accept 0 amplitude_bits The specification does not prevent an encoder to write the amplitude 0 as 0 amplitude_bits. Our get_bits() implementation might not support a zero sized read properly, thus the additional branch.	12 years ago
Luca Barbato	5b47c19bfd	vorbisdec: Add missing checks Rate and order must not be 0 even if the specification does not say that explicitly.	12 years ago
Luca Barbato	fc386f2eea	vorbisdec: cosmetics Use the commonly used "if (!var)" instead of "if (var == 0)".	12 years ago
Michael Niedermayer	11dcecfcca	vorbisdec: Error on bark_map_size equal to 0. The value is used to calculate output LSP curve and a division by zero and out of array accesses would occur.

Justin Ruggles	b2eea615c0	lavr: allow setting internal_sample_fmt option by string	12 years ago
Justin Ruggles	50f4337a2f	lavr: Add "resample_cutoff" option as a duplicate of "cutoff" Avoids an option name conflict with libavcodec, which is needed in order to work properly with avconv.	12 years ago
Justin Ruggles	5c7db097eb	avconv: pass libavresample options to AVFilterGraph	12 years ago
Justin Ruggles	9f1223562e	lavfi: connect libavresample options to af_resample via AVFilterGraph	12 years ago
Justin Ruggles	d7c450436f	ac3dec: validate channel output mode against channel count Damaged frames can lead to a mismatch, which can cause a segfault due to using an incorrect channel mapping. CC:libav-stable@libav.org	12 years ago

Diego Biurrun	040c565e51	doc: developer: Allow tabs in the vim configuration for Automake files While we do not use Automake in libav, this allows our config to be used more globally without introducing unwanted breakage.	12 years ago
Diego Biurrun	94ee7da08d	Remove pointless av_cold attributes in header files The init functions marked as av_cold have to be executed in any case, so there is no gain from trying to mark paths leading to such functions as unlikely.	12 years ago
Kostya Shishkov	b5f536d24b	pnm: add high-bitdepth PGMYUV support for both encoder and decoder	12 years ago
John Van Sickle	2f325a6fd4	libx264: change i_qfactor to use x264cli's default This also allows libx264 to modify its i_qfactor value when using the "-tune" setting. Previously it had a static value of 1.25 Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago

Anton Khirnov	ddfe1246d9	flicvideo: avoid an infinite loop in byte run compression When byte_run is 0, pixel_countdown is not touched and the loop will run forever. CC:libav-stable@libav.org	12 years ago

Matt Wolenetz	311443f6c7	x86: h264: Don't use redzone in AVX h264_deblock on Win64 This fixes crashes in chromium on win64 on machines with AVX (crashes that apparently aren't triggered by fate). Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Diego Biurrun	8a11ce43d0	build: Ensure that output directories for header objects are created	12 years ago
Martin Storsjö	26ee5ca03d	h264: Get rid of unnecessary casts This gets rid of a number of warnings about casts discarding qualifiers from the pointer target, present since `7ebfb466a`. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	fae6fd5b87	h264/svq3: Stop using draw_edges Instead, only extend edges on-demand when the motion vector actually crosses the visible decoded area using ff_emulated_edge_mc(). This changes decoding time for cathedral from 8.722sec to 8.706sec, i.e. 0.2% faster overall. More generally (VP8 uses this also), low-motion content gets significant speed improvements, whereas high-motion content tends to decode in approximately the same time. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	7ebfb466ae	h264: Don't store intra pcm samples in h->mb Instead, keep them in the bitstream buffer until we read them verbatim, this saves a memcpy() and a subsequent clearing of the target buffer. decode_cabac+decode_mb for a sample file (CAPM3_Sony_D.jsv) goes from 6121.4 to 6095.5 cycles, i.e. 26 cycles faster. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	9918f57dcf	get_bits: Return pointer to buffer that is the result of the alignment This allows more transparent mixing of get_bits and whole-byte access without having to touch get_bits internals. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	2ed008204d	h264: Add add_pixels4/8() to h264dsp, and remove add_pixels4 from dsputil These functions are mostly H264-specific (the only other user I can spot is bink), and this allows us to special-case some functionality for H264. Also remove the 16-bit-coeff with >8bpp versions (unused) and merge the duplicate 32-bit-coeff for >8bpp (identical). Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	e5ffffe48d	h264chroma: Remove duplicate 9/10 bit functions These functions do the same thing in 16 bit space and don't need any depth specific clipping. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
