1 week ago Thanks for describing the issue. If I understand correctly, you can achieve what you need with the --extra-output-options option and pass the -ac option there. Please refer to the README for some examples.
The reason why there's not a dedicated option for this (yet) is that I didn't want to map every single ffmpeg option. That said, the audio channel option is used often, so it could make sense to add it explicitly.

Describe the solution you'd like A clear and concise description of what you want to happen. When I'm using QLab on an input device, for example, it often happens that the source I get is mono. I always send these source files through ffmpeg-normalize so that I can play sound files with roughly the same loudness and codec by default, but when I convert mono sounds, I sometimes have complications with channel routing, especially when a Dante/AVB system is involved. This could easily be solved with an extra switch, which if specified, forces ffmpeg to use the "-ac 2" switch. It's a universal solution, because actually if the ffmpeg detects the input as stereo by default, the switch does nothing, and if it detects mono, it puts the same track in for both channels.
