Multychanel audio maping

[kselltrum]

Good day.

I send to restremer strem (by rtmp) with 6 ch AAC audio. It includes 3 languages (3 stereo pair). Can i transcode this stream to 3 independent streams (and send to YouTUBE) with stereo and chanel maping (1,2 -> stream1 , 3,4 -> stream2, 5,6 -> stream3)

Thank you for the answer

I can to do this with ffmpeg
ffmpeg -i rtmp://srv/stream -map 0:v -c:v copy -filter_complex "pan=stereo|c0=c0|c1=c1" -c:a aac -ac 2 /Users/user1/Desktop/lang1.mp4
ffmpeg -i rtmp://srv/stream -map 0:v -c:v copy -filter_complex "pan=stereo|c0=c2|c1=c3" -c:a aac -ac 2 /Users/user1/Desktop/lang2.mp4

But I don't know how to add custom ffmpeg options to restreamer?

Currently it's not possible to add custom ffmpeg options to Restreamer.

[kselltrum]

Is it planned to add this option in the future?
