Michael Niedermayer	2f76157eb0	swresample/rematrix: Use clipping s16 rematrixing if overflows are possible Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Michael Niedermayer	7fe81bc4f8	swresample/rematrix: Use error diffusion to avoid error in the DC component of the matrix This fixes the sum of the integer coefficients ending up summing to a value larger than the value representing unity. This issue occurs with qN0.dts when converting to stereo Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
wm4	cdf4a13f86	swresample: slightly nicer debug output for auto matrix This is the matrix that will be used for up/downmixing.	9 years ago
Michael Niedermayer	52acd22a7d	libswresample/rematrix: Check for malloc errors Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	80a28c7509	swresample: Allow reinitialization without ever setting channel layouts	10 years ago
Michael Niedermayer	b74ecb82fa	swresample/x86/rematrix_init: Check av_malloc* return codes, forward errors Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Reimar Döffinger	2c5c37ade1	libswresample: move condition to start of loop. This avoids several issue like calculating sum/maxcoef incorrectly due to adding up matrix entries that will be overwritten, as well as out-of-range writes to s->matrix if the maximum allowed number of channels is used. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	10 years ago
Reimar Döffinger	284123d7fd	Remove pointless if. A branch to avoid some calculation seems unlikely to have any benefits. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	10 years ago
Reimar Döffinger	2231d5b671	libswresample: Avoid needlessly large on-stack array. We only actually need to use a tiny part of it. Unfortunately we seem to have no real test coverage on the code, so this is a bit risky. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	10 years ago
Michael Niedermayer	291d464161	swresample: fix AV_CH_LAYOUT_STEREO_DOWNMIX input Fixes Ticket 3542 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	c56d4dab03	swr/rematrix: Fix handling of AV_CH_LAYOUT_STEREO_DOWNMIX output Fixes Ticket2859 Note, testcases related to the downmix channels are welcome. (id like to make sure this is working correctly now, as obviously it didnt work before ...) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Paul B Mahol	1acd2f6ba7	Replace rest of libavutil/audioconvert.h with libavutil/channel_layout.h Also remove it in once case when it is not needed. Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
