Shared Mode not working

[LearnedVector]

I am not able to open up the Virtual cam on multiple camera apps (i.e. zoom and obs).

It seems like you have MF_DEVICESTREAM_FRAMESERVER_SHARED set to 1 but still not able to share! Anything we need to do to get this working for multiple apps?

VCamSample's code is inspired (but I believe more simple and easier to understand) from the official Microsoft sample here https://github.com/microsoft/Windows-Camera/tree/master/Samples/VirtualCamera, you could try if it does the same (I think it does).

Anyway sharing a camera is most of the time not related to the camera itself but more to how clients open it. I can't use my real camera with obs or https://googlechrome.github.io/samples/image-capture/grab-frame-take-photo.html either (don't have zoom), if I open it with Windows 11's Camera app for example, ie: it's more a camera client thing.

Hmmm, ok i also noticed this doesn't work on chrome browsers... is that expected or something on my end? to be specific, it seems to not be working on google meets

for more context, i went to this site https://webcamtests.com/ and tested your vcam implementation, and it says "busy or block". note that i do not have any other camera app opened. Just want to confirm you are also seeing similar things?

hi again! just wanted to include additional context. Whenever i disable Media foundation video capture on chrome, it works!

I don't have any problem with this site, running on chrome, Edge or FireFox, with Chrome's "MediaFoundation Video Capture" settings just configured by Default.
