Beta-testers for GStreamer plugin (OS X)

  • Dear all. I am finishing the development of a GStreamer plugin for Isadora.

    So far I have tested
         rtsp stream ([rtsp://](rtsp:// in the picture below).
         http stream from youtube
        Raspberry Pi camera kit 1080p realtime stream.
        file url (file:///Users/eight/Desktop/real0flow0tut/ -- for movies
        file url (file:///Users/eight/Desktop/Solnce.wav) -- for audio wav files
    If you would like to help testing this plugin in your setup, suggest features etc, please PM me and I will be happy to send you a beta-build.

  • Tech Staff

    I would be happy to give it a run..  (I have Mac and PC)
    This seems like a great addition to Izzy.

    any chance of a PC version down the road?

  • Beta Platinum

    Sounds great!

    Also interested (Mac and PC)

  • Hi Guys,

    I sent you a PM with the instructions.
    PC version should be doable. I am planning to give it a go, once the OS X version is released and I find a Windows machine.

    Thank you!

    Installed the framework, placed the plugin, but no success  d803e6-screenshot-2015-01-29-09.26.15.png

    Oh, double clicked the projector and then it worked

  • Izzy Guru

    Cool. Really clever.

  • @eight
    would love to try this out also :)
    great work!

  • @feinsinn: I don't see how double clicking on the projector could affect GStreamer -- I think that you perhaps had a buffering moment.

    @primaldivine: sent you instructions.

  • @eight, cool stuff, like this and try. thx rainbow

    Just tried with a youtube stream and worked perfect

  • For those with Raspberry PI:

    To use Raspberry Pi as a HTTP video source:
        On RPI execute: 
             raspivid -o - -t 0 -hf -w 640 -h 360 -fps 25|cvlc -vvv stream:///dev/stdin --sout '#standard{access=http,mux=ts,dst=:8090}' :demux=h264
        In Isadora GStreamer: set URL to
    To use Raspberry PI as RTSP video source:
        On RPI execute:
             raspivid -o - -t 9999999 |cvlc -vvv stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/}' :demux=h264
        In Isadora GStreamer: set URL to
    To use Raspberry PI as RTSP video source with pi_streamer (

    Build pi_streamer according to
    Execute pi_streamer > > /dev/null

    I managed to take a picture as I followed the steps in this post

    So the camera is recognized by the Raspberry PI.
    Tried the commands, but it says command not found see photos attached

  • It says cvlc kommando nicht gefunden. You have to install vlc player that is encoding video into rtsp.

    sudo apt-get install vlc
  • Beta Platinum

    Ok installed the vlc player.

    Now I get a full screen video feed out of the rasperry. I have connected it to my Blackmagic Intensity shuttle and routed the hdmi to my stage.
    But not via Gstreamer. I dont know how to get back to the rasperry command line...

  • To get back to your RPi command line press Ctrl + C (or CMND+C).

    I am not sure what Blackmagic shuttle is here for.

    Can you ping your RPi from the computer that runs Isadora?

  • I´d love to give it a try, sounds promising..


  • I'd love to test it also, especially http stream from youtube

  • @ eight

    Tested the plugin.

    Setup Mac mini latest OS X, iPad mini and iVigilo,

    G-Streamer plugin 320x240 20 FPS

    IP camera QC patch 640x480 60 FPS



  • Beta Platinum

    I use the blackmagic for the display on my second monitor.
    I followed that tutorial:
    the next I´m trying:
    Here I am stuck: when I execute ping gateway on rasperry pi it works and mac terminal also see screenshots. So the next step ping raspberry.local is not working
