Hi Everyone,

Is it possible to get a live stream from YouTube into Isadora?

Many thanks

Yes. I have done this and then used Izzy map to shape it etc

Your friendly applications here are NDI or Syphon (spout for PC).

I used NDI Screen Capture to capture the youtube/chrome app and then used an NDI watcher actor in Isadora. It was all quite straightforward. There are probably better and more elegant ways to do it but NDI feed from chrome into isadora worked for me.

I did not have to worry about the audio as I just piped this straight into the PA.

It worked pretty well. Sometimes the video being projected stuttered but just keep an eye on it and have a 2nd computer backing up if need be..

My stutter (I reckon) was due to the youtube feed being a live stream from a couple of sources as well as being streamed to me.

You can use the Screen Capture actor: https://troikatronix.com/add-ons/screen-capture/

For the reverse direction (streaming to YouTube from Isadora) you can use the RTMP Streamer actor: https://troikatronix.com/add-ons/rtmp-streamer/

Best wishes,

@woland it looks like streaming from youtube to Isadora seems good, particularly if I take out a YouTube subscription. Is there any advantage Izzycast offers over this process? It seems more expensive but the same quality.

thanks, Nic

It's an apples and oranges comparison; they're totally different. IzzyCast is not meant to be a replacement for the RTMP Streamer actor (which lets you livestream from Isadora to Facebook Live, YouTube, Twitch, etc.), it's a remote performance tool.

Once the RTMP Streamer is streaming to an online platform, audience members can then watch the performance through the online platform.

Once the host (usually technician/director) and the participants (performers) are connected to an IzzyCast Session, they can use the IzzyCast actors to send and receive live video, audio, and data (like motion capture data or text) to each other so it can be integrated directly into the Isadora’s node-based programming environment. Example use-cases:

Actors and dancers from multiple remote locations can join live performers onstage
For live remote performance, since IzzyCast can transmit data, you can give remote performers standby warnings or other instructions on a second monitor or control a tally light to give them cues.
For data-driven performances, you can have a remote performer with a Kinect or motion capture suit send tracking data to you over IzzyCast, or have a polling mechanic for audiences in theatres in Oslo and Paris that affects what happens in the part of the performance happening in the theatre located in other city.
For broadcast and live events, IzzyCast's data transmission capabilities let producers, directors, and technicians make adjustments to their talent’s setup remotely by controlling hardware like PTZ cameras and DMX lighting instruments.

TLDR:

Streaming (RTMP Streamer Actor): A tool for presenting a performance to an online audience online. Video and audio can only travel in one direction (from you to the audience).

IzzyCast (IzzyCast Actors): A tool for creating remote or hybrid performances, the final result of which can then be streamed online, shown in one or more theatres to live audiences, piped into a zoom call etc,. Video, audio, and data can travel in any direction between all the performers and technicians, offering a lot more flexibility than just sending video and audio to the audience.

Re-reading this, I'm actually not entirely certain that I know what you're asking.

If you want a livestream from Youtube to come into Isadora, you'd use the Screen Capture actor. If that's what you want to do, since there's not an IzzyCast actor that does screen capture, I don't quite understand what you were asking if IzzyCast could be used for in the example of pulling a Youtube livestream into Isadora.

If you wanted to pump a Youtube livestream into an IzzyCast Session, you'd just use a Screen Capture actor into an IzzyCast Broadcaster.

@woland Thanks everyone, yes apologies, I was just after a simple task of streaming HD video from a remote camera into Isadora. Of course, the ScreenCapture actor does just that. I eventually want to stream 4k, but this is more to do with the bandwidth of the various platforms rather than any Izzy issues.

You should chat with the folks at Office Hours Global. They're always pushing the limits of what's possible when it comes to broadcast and streaming. I've been hanging out there for years and they're all super knowledgable and friendly.
