Is there any way to figure out what the actual error is? Even with
loglevel debug, all I get is this:
Successfully opened the file.
[Parsed_channelsplit_0 @ 0x55f0a8d38780] Setting 'channel_layout' to value '7.1'
[Parsed_channelsplit_0 @ 0x55f0a8d38780] Setting 'channels' to value 'LF|RF'

'channelsplit' with args 'channel_layout=7.1:channels=LF|RF'
