Jan Ekström	1c7e55dd50	swresample/rematrix: handle 22.2 as a 9 channel layout This is as far as 22.2 follows the same channel order as WaveFormatExtensible's channel mask (and the AV_CH_* defines). After LFE2 the side channels would follow, but that offset of one stops us from utilizing them without further tweaks. This change was verified by using swresample to downmix to 5.1, and then feeding that to WASAPI.	4 years ago
Jan Ekström	f5390a9f86	swresample/rematrix: treat 22.2 as 5.1 (back) when mixing Only this sub-set of channels actually follows the bit mask order in the official 22.2 channel mapping. Additionally, the 5.1 channels are there for backwards compatibility with the previous system. This enables the utilization of 22.2 content until a proper down/up matrix is added into swresample.	4 years ago
Jan Ekström	2fd8add1ba	swresample/matrix: switch internal clean_layout function to not drop high bits These bits are utilized by channel layouts such as 22.2. If those are dropped, the returned channel layout is no longer a match against the AV_CH_LAYOUT define when returned from this function.	4 years ago
Marcin Gorzel	8b710ea5e7	swresample: Use channel count in rematrix initialization Rematrixing supports up to 64 channels. However, there is only a limited number of channel layouts defined. Since the in/out channel count is currently obtained from the channel layout, for undefined layouts (e.g. for 9, 10, 11 channels etc.) the rematrixing fails. This patch changes rematrix init methods to use in (used) and out channel count directly instead of computing it from channel layout.

Tobias Rapp	6325bd3717	swresample/rematrix: fix update of channel matrix if input or output layout is undefined Prefer direct in/out channel count values over channel layout, when available. Fixes a pan filter bug (ticket #6790). Signed-off-by: Tobias Rapp <t.rapp@noa-archive.com>	7 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.

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.

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
