verify that they are having a problem with the C270 on Mac OS X?”

I can verify that there is inconsistent and unexpected behavior using my Logitech c930e webcam similar to what has been posted previously by @Woland and others “ n the Live Capture Settings, when we went to select the Logitech C920, we sometimes wouldn't get a feed and it would show up as "disabled". I can’t recreate this behavior each time, but the last occurrence happened during a setup for a gallery installation that also used usb for communicating with other devices such as an Arduino. And where a usb hub was also connected to the computer (but not the same port as the camera), this was using an older usb2 Mac book pro 2012.

I have not seen the issue on a later usb3 MacBook Pro, except for having to relaunch the application before it will find the camera connection.

I have troubles connecting the C270 and another webcam I have (I don't know the brand).

Dear Shawnu, (and team @Michel @Skulpture @DusX @mc_monte @crystalhorizon)

So I purchased a C270 today and tested it on a Mac Book Pro running Yosemite and High Sierra, and on a mini Mac running High Sierra. I tested with 2.5.2 and the current beta, and in all cases, the camera showed up and connected without any trouble at all.

But I think –- after the many posts and suggestions here -- we all forgot to ask a critical question: did you have both cameras connected at the same time? Trying to use two HD webcams on the same USB bus is probably impossible, because the bandwidth requirements are too high. (Specifically, these cameras are USB 2, so they don't have USB 3 bandwidth.)

Could that be the case, since you mention two web cams?

Can anyone else verify that they are having a problem with the C270 on Mac OS X?

Best Wishes,
Mark

Yes, I've run tests with my Logitech C920, which reliably works. It's full HD, has a nice soft autofocus, and easy to mount on a tripod or fixed position. I've been using them for years with Isadora for capture and streaming. They are less then $100 Canadian, but I picked up three for half price each that years ago.

 Logitech also has Logitech Camera Settings applications that are free but oddly hard to find, and also usually specific to a certain model. It allows you do zoom in, pan, has various image settings you can change, and allows you disable things like autofocus. I think this is the link I saved for the c920 version. https://itunes.apple.com/us/ap...

Welcome! It was an oddly-specific, but easy, work-around so I thought I’d share.

I can report that my Logitec C930e does not connect directly through the Isadora 'Live Capture Settings' and does not appear after 'Scan for Devices'. The camera only appears after launching in Facetime and after Isadora is restarted. Thanks @Woland.

If all else fails (on a Mac) you can open Photobooth, get a feed from the camera, then use the free software Syphoner for capture with the free software Syphon to “brute force” a video feed into Isadora with the Syphone Receiver act

I've just gotten one member of the team involved on this ongoing issue. We'll see if we can't get it nailed down for v2.6

Best Wishes,Mark

If you’re on Windows, you’ll use Spout instead of Syphon, Spout Receiver actor(?), and I’m going to tag in @Maximortal and @Skulpture because I don’t know what generic webcam application you’d use on Windows, nor what application to use to capture said feed into Spout.
