Vignesh Venkatasubramanian	48de04f4ec	avcodec/avpacket: Refactoring copy_side_data into a separate function Refactoring copy_side_data into a separate function so that it can be called in cases where side data needs to be duplicated. Signed-off-by: Vignesh Venkatasubramanian <vigneshv@google.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	5d22ac488b	libx264: zero x264_picture before use. This prevents use of uninitialized memory by ffmpeg later (i_qpplus1) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Hendrik Leppkes	fe06795d78	vc1: implement frame interlaced b-frame header parsing Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	46430fd47c	vc1dec: Don't attempt error concealment on field pictures This is not implemented and doesn't work. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Sebastian Sandberg	1bd57a850a	vc1dec: fieldtx is only valid for interlaced frame pictures The fieldtx_plane is not cleared for interlaced fields. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Claudio Freire	8bbdd20a29	aacenc: Fix erasure of surround channels This was due to a miscomputation of s->cur_channel, which led to psy-based encoders using the psy coefficients for the wrong channel. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Claudio Freire	f4d0a63b5b	aacenc: Fix target bitrate for twoloop quantiser search This fixes a case where multichannel bitrate isn't accurately targetted by psy model alone, never achieving the target bitrate. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Michael Niedermayer	1e00bbb10c	avcodec/lcldec: Check that dimensions are a multiple of the subsample factors Other dimensions would not work correctly currently, also ask for a sample for files that fail this check. This fixes an integer overflow leading to out of array accesses. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Paul B Mahol	8671e995c8	imgconvert: silence "incompatible pointer type" warning Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago

Paul B Mahol	ae9ef151ad	dpxenc: simplifiy code using AVPixFmtDescriptor Update rgb24 fate test as it no longer writes image in big endian format. Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
Paul B Mahol	22a038606c	dpxenc: do not set coded_frame Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
Diego Biurrun	1399931d07	x86: dsputil: Rename dsputil_mmx.h --> dsputil_x86.h The header is not (anymore) MMX-specific.	12 years ago
Diego Biurrun	245b76a108	x86: dsputil: Split inline assembly from init code Also remove some pointless comments.	12 years ago
Diego Biurrun	46bb456853	x86: dsputil: Refactor pixels16 wrapper functions with a macro	12 years ago
Diego Biurrun	f54b55058a	configure: Rename cmov processor capability to i686 The goal is to make the capapility slightly more general and have it cover the availability of the nopl instruction in addition to cmov.	12 years ago
Claudio Freire	e41cd3cdeb	aacenc: Fix ticket #1784 : erasure of surround channels This was due to a miscomputation of s->cur_channel, which led to psy-based encoders using the psy coefficients for the wrong channel. Test sample attached on the bug tracker had the peculiar case of all other channels being silent, so the error was far more noticeable.

Michael Niedermayer	a0c0900e47	ffv1dec: Support frame threading with gop > 1 This is about 20-30% faster than slice threading Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

James Almer	22c7784f60	adpcm_thp: Allow the use of extradata for the adpcm table There are several containers that support adpcm_thp (Also known as Gamecube DSP) streams, but only thp files contain the coeff table and previous sample inside each frame. Some don't even contain previous sample information at all. This change will make it easier to implement demuxers for said containers without having to create a new decoder.

Janne Grunau	94235f2ba2	indeo3: avoid writes without necessary alignment in copy_cell() Cells starting at a position aligned to 8 pixels but wider than 4 blocks are copied with 3 blocks per loop. This creates problems on the next loop iterations since the routine copying 2 blocks requires the same alignment on some architectures like ARM NEON.	12 years ago
