Syphon Virtual Webcam - Questions & Assistance

GertjanB

Good news,

I just had a full day of very long only meetings, in google meet (chrome) and zoom. (one time even 2 meetings at the same time meet & zoom)

I did all the meetings trough Isadora and syphon virtual webcam (also because I have made a handy tool with the buffer and a random value player so it looks like I'm present)

And I didn't have any crashes or freezes. (after now 10h).

Thanks for testing, but don't worry about b38. I tested in 3.0.7 and the latest beta (b44) and Isadora accepts the virtual webcam fine.

For the benefit of those new to Isadora: because Isadora accepts Syphon natively, there is no reason to use Syphon Virtual Webcam as an input to Isadora. You should just use the Syphon Receiver actor to receive the signal directly.

Best Wishes,

hello everyone, I've been pushing Syphon Virtual Webcam pretty hard today and had a couple of freezes. i'm running video out of Isadora thru SVW into OBS.Ninja in Chrome. twice today the image froze up at my end and the people on the other end of Ninja said that there was a message from SVW on their screen. I closed SVW and the whole computer froze up and needed hard rebooting. same thing both times (i didn't have time to wait to see if it would come back to life on its own)
its the latest version of SVW from the plugins page on my MacBook Pro running 10.13.6.

OK. I've never worked with Ninja, so we can give this a try.

Importance Questions: Please Answer in your reply!

Do you have OBS v26.1 or later installed on your computer?

What was the resolution of the source image?

And what message did SVW display exactly? It doesn't display a message... the only thing it will do is to show the "test pattern" screen if the connection drops. Is that what they mean?

hi Mark,

i have OBS v23.1 installed, but probably installed v26 last Summer, and then uninstalled it and reverted to v23 when i discovered i couldn't use a Ninja link as a browser source. i usually use AppZapper to remove stuff, but it may have left something behind.

source image is 1280x800 to match the projectors we're using.

the Hungarian company said that they got a message onscreen saying something like Syphon Virtual Webcam has stopped working. it was a bit difficult to tell what was going on at the time because of the video freezing and me trying to work out what was going on. the message may have been generated by Ninja.

cheers,

john

It may not know about the location of the driver. It lives at

/Library/CoreMediaIO/Plug-Ins/DAL/

in any case, the v0.9.6 version of Syphon Virtual Webcam works with both the old driver and the new one from OBS 26.1. But if you really want to downgrade, then

quit everything
go to /Library/CoreMediaIO/Plug-Ins/DAL/
delete obs-mac-virtualcam.plugin
and restart Syphon Virtual Webcam

In any case, thanks for the info. I'm a bit slammed at the moment, but I will see what I can find out as soon as I can.

Best Wishes,
Mark

i fixed another issue, which means i can use my iMac instead of my Macbook for this project - today, with the same setup on the iMac, SVW has been stable. thanks for the advice. i'll try it on my laptop at some point and report back.

It's been a while since I've used Syphon, but I've used it successfully in the past. I just tried to get it up and going, but Zoom didn't recognize it. I followed the steps above to uninstall everything and started from scratch.

Now, when I try to open Syphon (to then re-install the OBS Virtual Cam), the icon appears on the dock, but the actual window doesn't appear. If I go to help>install OBS Virtual Camera Plugin it waits and then closes the Syphon app. I can't get any further. Any ideas?

Best,

It might not be compatible with macOS Sonoma

@woland I feared this might be the case

Microsoft: If someone makes a program for our OS, it should be able to run forever.

Apple: Let's break everything every single year. Lol

RWillats

@woland Hahahaha

and getting NDI into zoom is still really pricey--I think I might just be stuck with this one

@rwillats

You could check and see if OBS's actual virtual webcam plugin for OBS has been updated to support Sonoma. You should be able to get Isadora or NDI output into OBS. That might be a path forward.
