I have video stream with AAC sound with 3 lang audio tracks (UK, EN, DE). I want to transcode it to three dedecsted streams with stereo AAC audio (stream1 - video + audio track 1,2, stream2 - video + audio track 3,4 etc.)

Hi @kselltrum , you may need a custom plug-in/module to make this happen.

Depending on the ingest protocol and container type, it may be possible to let a module recognize the separate audio tracks and launch 2 new streams with the desired output.
