  • How can I broadcast a Twilio (group room) video conference ?

    2 novembre 2022, par Danish

    I have been trying different solutions/approaches for last few days and posting here to get some more options.

    



    I am planning to use Twilio's Programmable Video solution with Group room (upto 50 participants) to allow hosts/presenters to join video conference meeting. Right now I am able to setup and get started with quickstart example here

    



    Also, in parallel, I need to be able to broadcast that live meeting room through RTMP/HLS (audio+video) streaming that can be viewed (through another portal) by large user set (ideally around 10k+)

    



    Twilio support team suggested - integrating Twilio Video with Wowza using screenscrapping and ffmpeg (i.e. render the video into a (maybe virtual) screen, capture it and send to Wowza using ffmpeg.)

    



    I am new to both ffmpeg and wowza. However, I am looking to see high level solution which can be used to achieve this (with minimum hanging parts).

    



    Ideal flow i can think of is

    



      

    • Start a Twilio video conference room with actual presenters

      • 


    • all participants share there video and audio tracks with each other in the room - standard behavior

      • 


    • a new ghost-participant joins-in from stand-alone server (from wowza or SIP) and subscribes to audio-video tracks in conference.

      • 


    • arrange & combine those tracks into one channel and stream it as HLS

      • 


    • this ghost-participant will also be able to identify dominant speaker and re-arrange video tracks to show current speaker occupying bigger space (just like zoom)

      • 


    • and of course, this streamed video (with audio) will be one-way and viewers cannot interact. Just see be able to see the room broadcasting.

      • 


    



    Also/FYI
I have tried exploring few more options below (with no success)

    



      


    1. a blog here explain how can we broadcast a twilio audio
conference. At the bottom it also mention about video streaming. but, I am not getting how can we use SIP to get video stream that can be broadcasted. Also, how can I manipulate video tracks to show dominant speakers in full screen view Vs other participant in thumbnail view i.e. custom layouts.

      2. 


    2. I also explored option of Wowza WebRTC streaming to achieve this, but it has got other technical challenges with setting up video room with multiple participants. I am going to reach out to them to see if this use-case is possible with their offering.

      3. 


    3. I am looking for something as simple as here - dial as guest participant into video room from standalone streaming server/wowza server. And get output as single stream to broadcast.

      4. 


    



    Any other pointers or links to solutions would be helpful.
