Here is a wav file, it is 12 channels: http://itstar.co.uk/test.wav
I need to be able to get just 1 specific channel out of it with FFMPEG.
All the documented methods including -af pan and -map_channel are not
working and producing an empty output file.
Examples of commands I tried include:
{{{
ffmpeg -i test.wav -af "pan=0x4|c0=c4" -y c4.wav
ffmpeg -i test.wav -map_channel 0.0.5 -y c5.wav
for i in 0 1 2 3 4 5 6 7 8 9 10 11; do ffmpeg -i test.wav -af
"pan=1|c0=c${i}" -y ch${i}.wav; done
}}}
All of the above produce empty/silence output wav files.
Any ideas?
