Nicolas George 4a640a6ac8 lswr: fix assert failure on unknown layouts. 2013-11-03 10:30:37 +01:00
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 ...)
