Hello all

   I know this has been discussed in past, but doe's anyone have a working file or some suggestions of how to write a cue that will display a webpage?

You can do this with Camtwist  Camtwist allows you to define an area of your screen or an application window which will appear to Qlab as a camera input. So as long as you have the screen space for Qlab and whatever you want to put on your Qlab projector on your opertors screen you can use any program as a video output to Qlab,

I could only get it to work with camtwist 3 beta available here  http://camtwiststudio.com/beta/

Because the beta may well be flakey I would test it very thoroughly before using it for anything important

Having said that I have it running as a 1280x720 video source rotated and with an added title in Qlab3 with a video playing on the web browser at full frame rate and it looks really good.

Alright...  after a lot of screwing around i finally got it going.    

We are still using version 2.3.9 of QLab.  So When I originally went to use CamTwist as a camera input it would not work. Discovered it's because it wouldn't show up to the QTCapture framework for that version of QLab. It Probably works in V3.    SO....  using the beta of version3 of CamTwist which was capturing an open webpage while running in the background.  I edited a fairly simple Quartz Composer file i found to capture the video input.   Then, in QLab I inserted a video file (of the same image size as the capture, in this case 1280x720).  I then selected that quartz file as a custom render over that video file.   It's running stable and the image looks great.  

I have attached the quartz file for anyone that might find it useful.

I’ve been working on a simple little app that simply captures a screen and outputs it via Syphon – so you can get your screen into any software that supports Syphon. It’s not quite done yet, but could probably finish it up and put something together if that would solve it for you.

You’ll just need QLab 3 Pro Video license.

I’ve also used Cam Twist in the past to do this. It works, but I can’t say it was a good experience. It didn’t crash on me too often… needs plenty of testing before you rely on it.

Nice! I never thought that in QLab 2 you could use a simple QC filter patch, instead of a modified standard renderer. The usual advice always told to one that want to have a particular renderer was, till now, "modify standard video.qtz". Creating a QC filter appears as another option. And, compatible with QLab3. Correct?

did this APP every get made?

There’s an app called syphoner that does this.

Hi,

I once tested Syphoner but when running in the background the Syphon input had a lack (even paused) after a while so I had to bring it in front from time to time which is not very handy of course. I prefer CamTwist (v3 beta) and we were running already 20 shows using CamTwist to capture Skype! ;-) There are also Syphon Virtual Screen and Screen Capture Syphon (US$10). And maybe this could help as well: CefWithSyphon (https://github.com/vibber/CefWithSyphon)

Finally I would suggest CamTwist. It's powerful, it's running in the background very nicely, you can control it via MIDI, and it's for free!

Yes I've found that Syphoner often doesn't update when it, and the target window are in the background. Also if you want to see the cursor on the Syphon feed then Syphoner only gives you a massive cross hair. CamTwist gives a normal size pointer. CamTwist is curently at 3.4 (although there is a beta 3.4.1)

Cefwithsyphon works pretty good. I’ll try camtwist too. Thank you so much for the guidance.
