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.

@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.

I believe the workaround is to change the Display Refresh setting in Isadora Preferences/Settings: 

I cant remember if "Off", "Scaled", or "Full" solves it, but I believe one of these settings solves the issue.

We're in communication with Apple about the problem, but progress has been slow.

I remember this issue coming up previously. It is something Mac is doing for power saving, and you're right there isn't any system setting to fix this. I don't know if we have worked around this in Isadora 4, but I believe the initial workaround was to programmatically 'wiggle' the mouse every couple minutes.
Not very elegant, but it works.

A quick search turns up a number of utilities for this purpose:

• Mouse Jiggler
• MacMouseJiggler
• Jiggler
• Computer Mouse Jiggler

I haven't tested any of these.. some are free some cost a couple dollars.  

I am having a very strange problem in Isadora 3.2.6. I have a simple patch to play 2 HD videos (I've tried ProRes, H265 and H264 and am playing from a Samsung T7 SSD) to 2 stages on 2 projectors. After exactly 5 minutes the frame rate drops from 25 to 23  or 24 fps causing the video to drop frames. I am using a MacbookPro M3 Pro with 18 GB RAM and Sonoma 14.6.1. The computer should have no problem playing 2 HD videos to 2 stages (and they play perfectly until 5 minutes in). If I hit a key on the keyboard or touch the touch pad the frame rate goes back up for another 5 minutes. I've turned off every setting in Mac Preferences that kicked in after 5 minutes as well as my autosave in Isadora but no luck.

Does anyone have a suggestion as to what might be the culprit?

Thanks,

Ur

*not actually GoPro, but I used a FLIR C5 thermal camera recently, connected via USB extension, and it showed up as a Video source in the Live Capture Settings menu. Which was nice.

@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.

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.

By default Projector actors are not connected to each other at all. If you want to have the same mapping in all of them but be able to adjust different inputs on them, you should wrap a Projector actor in a User Actor and add User Inputs connected to the inputs on the Projector actor that you want to be individual to specific Scenes.

See this video tutorial about Isadora User Actors for more details.

I am having good success with wired connections from the GoPro Hero Black 6 and now the GoPro 12 (with media mod and the GoPro Labs firmware). My methods remain the same as my post from September 2020, above.

I see it's been a while since you've posted, but I just want to ask if anyone has tried using a GoPro with Isadora more recently, especially with newer models like the Hero 10 or 11. Are you still using wireless methods or has anyone figured out a way to get a stable wired feed into Isadora on Mac or Windows without a lot of fuss? Curious how things have evolved.
