Multistream Help

[Jim O'Carroll]

I have what I'd describe as a fairly rudimentary understanding of Janus, Have an application where I've successfully displayed 3 concurrent video streams in separate iframes. Streams originate from 3 cameras on a locally connected raspberry pi using Gstreamer. Streaming config file has 3 separate mountpoints e.g.  

h264-ExploreHD: {
        type = "rtp"
        id = 6
        description = "H.264 live stream coming from ExploreHD Camera"
        audio = false
        video = true
        videoport = 8006
        videopt = 126
        videortpmap = "H264/90000"
        videofmtp = "profile-level-id=42e01f;packetization-mode=1"
}

I have tried unsuccessfully to create a Multistream configuration with no success - expect I'm missing something obvious - not to me :-) I simply added a multistream section to the config file per below and used the multistream demo html/JS code. I did not change any of the core files. First and obvious problem is that the returned stream list does not contain the multistream test entry below. 

1. {streaming: 'list', list: Array(6)}
   1. list: Array(6)
      1. 0: {id: 1, type: 'live', description: 'Opus/VP8 live stream coming from external source', metadata: 'You can use this metadata section to put any info you want!', enabled: true, …}
      2. 1: {id: 2, type: 'live', description: 'a-law file source (radio broadcast)', enabled: true}
      3. 2: {id: 3, type: 'on demand', description: 'mu-law file jim source (music)', enabled: true}
      4. 3: {id: 4, type: 'live', description: 'H.264 live stream coming from Blue Rov', enabled: true, video_age_ms: 15}
      5. 4: {id: 5, type: 'live', description: 'H.264 live stream coming from Pi Camera', enabled: true, video_age_ms: 20}
      6. 5: {id: 6, type: 'live', description: 'H.264 live stream coming from ExploreHD Camera', enabled: true, video_age_ms: 26}

Hoping for some guidance. Thanks.

        type = "rtp"

Multistream its for videoroom plugin, not for straming plugin.

What?! Absolutely NOT! The Streaming plugin DOES support multistream! There's even a demo on the website for that!

This is the syntax for the multistream branch of Janus, is that what you're testing or did you install Janus master?

Ciao Lorenzo

Thank you for the speedy response. I was trying it with Master and suspected that was the issue once I realized there was a separate multistream branch. Do you plan to merge these?
