Hmm, I must be missing something here, because I get this error: $ ffmpeg -stats -y -i Original.mkv -filter_complex 'channelsplit=channel_layout=7.1:channels=LF|RF[lf][rf];[lf][rf]amerge=inputs=2[aout]' -map 0:v -map 0:s channel_split.mkv [AVFilterGraph @ 0x559f11cf7f80] Error initializing filter 'channelsplit' with args 'channel_layout=7.1:channels=LF|RF' Error initializing complex filters. Invalid argument But when I tried things along these lines, I got complaints that some of the outputs weren't connected to anything.
