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
