Trying to remap channels in a 7.1 Wave file, but that gives me a strange error.
(I’ve reduced my lines to the most simple to reproduce.)
When I use the same input file, but do a 5.1 remap it works as expected:
/Applications/ffmpeg -i /Volumes/Data/LC_testfiles/8chan.wav -filter_complex "[0:0][0:0][0:0][0:0][0:0][0:0]amerge=inputs=6,pan=5.1|c0=c0|c1=c1|c2=c2|c3=c3|c4=c4|c5=c5|[mix]" -map "[mix]" -f null -
BUT, with 7.1 it fails
/Applications/ffmpeg -i /Volumes/Data/LC_testfiles/8chan.wav -filter_complex "[0:0][0:0][0:0][0:0][0:0][0:0][0:0][0:0]amerge=inputs=8,pan=7.1|c0=c0|c1=c1|c2=c2|c3=c3|c4=c4|c5=c5|c6=c6|c7=c7|[mix]" -map "[mix]" -f null -
Is it me, or is this a bug?
