Anton Khirnov	1afddbe59e	avpacket: use AVBuffer to allow refcounting the packets. This will allow us to avoid copying the packets in many cases. This breaks ABI.	12 years ago
Alexander Kojevnikov	eae0879d96	mp3dec: Fix VBR bit rate parsing When parsing the Xing/Info tag, don't set the bit rate if it's an Info tag. When parsing the stream, don't override the bit rate if it's already set, otherwise calculate the mean bit rate from parsed frames. This way, the bit rate will be set correctly both for CBR and VBR streams. CC:libav-stable@libav.org Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Diego Biurrun	dbd2a34ba5	build: cosmetics: Group hw accelerator Makefile entries together	12 years ago
Diego Biurrun	5f401b7b71	Add missing error_resilience includes to files that use ER	12 years ago
Martin Storsjö	d88738e403	mpegvideo: Conditionally build error_resilience bits This breaks the dependency of mpegvideo on error_resilience allowing compilation of components that depend on the former w/o the latter.	12 years ago
Reimar Döffinger	efa7f42020	Use the avstring.h locale-independent character type functions Make sure the behavior does not change with the locale. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	54b298fe56	lavc: Deprecate the deinterlace functions in libavcodec Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	64e4386974	h264: Integrate draw_horiz_band into ff_h264_draw_horiz_band This makes the decoder independent of mpegvideo. This copy of the draw_horiz_band code is simplified compared to the "generic" mpegvideo one which still has a number of special cases for different codecs. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Stefano Sabatini	70762508ec	lavc: Prettify printing of codec tags containing non alphanumeric characters Make av_get_codec_tag_string() show codec tag string characters in a more intelligible ways. For example the ascii char "@" is used as a number, so should be displayed like "[64]" rather than as a printable character. Apart alphanumeric chars, only the characters ' ' and '.' are used literally in codec tags, all the other characters represent numbers. This also avoids relying on locale-dependent character class functions. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	d65522e826	h264: Rename the jpeg_420 pixfmt list to match the common naming structure Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	8d061989dd	lavc: Split out ff_hwaccel_pixfmt_list_420[] over individual codecs Not all hwaccels implement all codecs, so using one single list for multiple such codecs means some codecs will be represented in the list, even though they don't actually handle that codec. Copying specific lists in each codec fixes that. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Diego Biurrun	5a4e9fe855	avcodec/internal: Fix #if DECODE_AUDIO / ENCODE_AUDIO name mismatch	12 years ago
Luca Barbato	5cf7c72757	shorten: use the unsigned type where needed get_uint returns an unsigned value, use an unsigned to store blocksize to make sure the comparison logic is correct and report correctly the error for the channel count not supported.	12 years ago
Luca Barbato	4c364eb2b8	shorten: report meaningful errors	12 years ago
Luca Barbato	a2ad554def	shorten: K&R formatting cosmetics	12 years ago
Michael Niedermayer	c10da30d84	shorten: set invalid channels count to 0 Prevent the loop shorten_decode_close from writing and freeing out of the array boundary. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Luca Barbato	02055b6d40	vorbisdec: check memory allocations	12 years ago
Luca Barbato	4987faee78	h264: check for luma and chroma bit dept being equal The decoder assumes a single bit depth for all the planes while the specification allows different bit depths for luma and chroma. Avoid the possible problems described in CVE-2013-2277 CC: libav-stable@libav.org	12 years ago
Diego Biurrun	c57a593670	hwaccel: consistent name prefixes for start_frame/end_frame/decode_slice Some hwaccels use name prefixes, some do not, others only use them for some codecs. Add prefixes everywhere for consistency.	12 years ago
Anton Khirnov	437211ae73	h264: set ref_count to 0 for intra slices. CC:libav-stable@libav.org	12 years ago
Anton Khirnov	668e16a0dd	h264: on reference overflow, reset the reference count to 0, not 1. Since decode_slice_header() returns before the reference lists are constructed, there are zero valid references. CC:libav-stable@libav.org	12 years ago
Anton Khirnov	e671d3ad6c	h264: do not copy ref count/ref2frm when updating per-frame context They are filled in decode_slice_header() anyway.	12 years ago
Diego Biurrun	e8c52271c4	Revert "Move H264/QPEL specific asm from dsputil.asm to h264_qpel_*.asm." This reverts commit `f90ff772e7`. The code should be put back in h264_qpel_8bit.asm, but unfortunately it is unconditionally used from dsputil_mmx.c since `71155d7`.	12 years ago
Luca Barbato	9d4da474f5	lls: move to the private namespace The functions are private.	12 years ago
Martin Storsjö	86611ff123	pnm: Use av_pix_fmt_desc_get instead of accessing the array directly This fixes boken fate tests with MSVC with DLLs, broken since `b5f536d24`. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Diego Biurrun	ebc701993f	x86: dsputil: Drop some unused function #defines	12 years ago
Diego Biurrun	845cfc92f9	x86: dsputil: Drop aliasing of ff_put_pixels8_mmx to ff_put_pixels8_mmxext The external assembly function uses mmxext instructions and should not be masqueraded as an mmx-only function. Instead, use the mmx-only inline assembly function.	12 years ago
Diego Biurrun	096cc11ec1	x86: vc1dsp: Move ff_avg_vc1_mspel_mc00_mmxext out of dsputil_mmx.c	12 years ago
Martin Storsjö	31a23a0dc6	x86: dsputil_mmx: Remove leftover inline assembly fragments These became unused in `71155d7b`. Signed-off-by: Martin Storsjö <martin@martin.st>	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	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	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
