safari safari-17.0, obs studio 30.0.0-beta3, osx sonoma: virtual cam selectable but not working

[ikzelf]

Description:

When using safari on osx sonoma on Apple M2, with a running virtual camera presented by obs studio 30.0.0-beta3 I can see the virtual cam, even with content in the cam selector but when I select it, jitsi falls back to the built in Facetime HD camera. The virtual cam is working fine in other apps, even Skype and also in https://webcamtests.com/

Steps to reproduce:

1. download OBM studio from https://obsproject.com Choose Apple Silicon when needed.
2. start OBM studio after installing
3. go to the general settings and enable the Beta / Release candidate channels
4. check updates and download and install the latest beta
5. download a nice plugin from https://github.com/obs-ai/obs-backgroundremoval/releases/tag/1.1.6
6. install it
7. restart OBS studio
8. Follow the instructions in the video on the obs-ai GitHub repository (it's about a v29 but works for the 30.0 beta too)
9. open https://meet.jit.si
10. start meeting (any meeting)
11. change preferences for Video and select OBS Virtual Camera
12. OK -> back to the default camera

Expected behavior:

After selecting the OBS Virtual Camera I was hoping to see it in the meeting window.

Actual behavior:

The selected camera is ignored and the actual camera is again the built in camera

Server information:

• Jitsi Meet version: the hosted one, no idea how to list the version
• Operating System: macOS Sonoma - 14.0

Client information:

• Browser / app version: safari 17.0
• Operating System: macos Sonoma - 14.0

Additional information:

The same response as with ManyCam as virtual camera provider.

no logs / traces to show here. Since it works on https://webcamtests.com/ I hope there is an easy fix for jitsi too.

What resolutions does the virtual camera support?

[ikzelf]

taken from https://webcamtests.com/: Webcam Name: OBS Virtual Camera Quality Rating: 269 Built-in Microphone: None Built-in Speaker: None Frame rate: 0 FPS Stream Type: video Image Mode: rgb Webcam MegaPixels: 2.07 MP Webcam Resolution: 1920×1080 Video Standard: FHD Aspect Ratio: 1.78 PNG File Size: 1.02 MB JPEG File Size: 1.01 MB Bitrate: NaN undefined/s Number of Colors: 3370

I hope this helps.

Can you try checking the supported resolutions in chrome://media-internals ?

[ikzelf]

Not sure if I understand you correctly, I am using Safari and not chrome. Where should I look for those supported resolutions?

I just found a private jitsi instance where the OBS Virtual Camera is working. How/where can I find the version of jitsi? It still is not working on https://meet.jit.si/

Does Chrome work?

It be related to configuration. Check the video constraints in the instance's config.js vs https://meet.jit.si/config.js

What I see in the meet.jit.si/config.js:

constraints: {
        video: {
                    height: {
                ideal: 720,
                max: 720,
                min: 180
            },
            width: {
                ideal: 1280,
                max: 1280,
                min: 320
            },
            frameRate: {
                max: 30,
                min: 15
            }
        }
    }

in the private instance:

    // constraints: {
    //     video: {
    //         height: {
    //             ideal: 720,
    //             max: 720,
    //             min: 240,
    //         },
    //     },
    // }

I am not sure how to read this .... 1280*720 the max allowed resolution? Does this explain that the virtual cam is shown in the cam selector and refused to show after it has been selected?

Constraint processing can be tricky since it's quite browser dependent. Does your camera only support 1080p ?

[ikzelf]

working with OBS beta support channel to get that fixed. It should be possible to have different output resolutions.

[ikzelf]

For some reason the changes I do in obs have no success in jitsi. There is quite a list of predefined resolutions: with a resolution of 768 × 432 I still can not use the OBS Virtual Cam on jitsi. I checked this resolution by recording the webcam, save it as a movie and checked the properties using quicktime player.

I also tried with 720x320 720x1280 which should be ideal resolutions but not a working cam in the public jitsi instance. https://meet.jit.si/

Does 720p not work?
