Re: [Helix-server-dev] Is that possible to stream 2 video tracks + 1 audio track concurrently?

For VoD, this should work correctly from the server, so long as the
content has separate video tracks which are not marked as part of the
same Alternate Group.

For RTP live, if there are multiple video streams, the server will
interpret them to be alternates, as there is no indicator to
differentiate alternate streams from concurrent streams for RTP live
ingress. There is currently no runtime configuration to disable
handling as alternates, but it should be very easy to simply disable
this (or make it configurable) in source and re-compile the RTP live
receiver plugin. Naturally, multi-rate RTP live feeds will not function
correctly with alternate streams disabled.

FYI on the player side, I believe this already works as expected with
the Helix client (and RealPlayer desktop player) so if you choose to go
that route you might not have much dev work to do!

Thanks,
Jamie
