Isn’t it possible to create an ABR output from an SRT/TS stream that embeds multiple audio tracks?

Hello !
So I have been doing some tests with WMSpannel, nimble and the SRT protocol, and I have a question regarding multiple audio tracks.
I did some research on the forum and found this:
https://blog.wmspanel.com/2016/12/multiple-audio-tracks-abr-hls-live.html

With this tutorial, one can produce an ABR stream with multiple video (different display resolutions) and multiple audio (different languages).

But it seems that it can be done only when there are already multiple streams coming out of nimble.

For my tests, I am using Gstreamer to send an SRT stream, with two different audio tracks, to nimble streamer, and then I create the ABR stream. But when I check the vidéo with the players proposed by wmspanel, there is no sign of the second audio track, not even in the HLS playlist.
That is why I assume that the ABR stream is created with multiple stream coming out of nimble and that lead to my question,

Isn’t it possible to create an ABR output from an SRT/TS stream that embeds multiple audio tracks?

Thanks for your time !

Hello.
Sure, that's easy to do with Nimble.

Your SRT/TS input has 2 Audio streams, but you defined video with the first audio stream only.
Please add one more MPEGTS OUT with the second audio track (Add outgoing stream button), name as a new stream, and specify the second audio stream in the Audio source. Add this stream to ABR.

Thank you.
