[FFmpeg-user] Audio Track Assignment Problem

Hiya, I was wonder if anyone could help with a track assignment question.

I need to change the assignment for 8 audio tracks from all mono to FL+FR+mono+LFE+BL+BR+DL+DR.

I can do this manually with a Mac utility called Multitrackmaker (Mixage), but I need to be able to automate the process.

I've tried to do this using things I've learned from the FFMPEG AudioChannelManipulation<https://trac.ffmpeg.org/wiki/AudioChannelManipulation> page, using a combination of -filter_complex & channel_layout.

However, all I get is errors such as "Error initializing complex filters" etc.

Any help would be appreciated.

Cheers! - Nate
