Two Instances from one Webcam

问题

I am new at DirectShow and found one example to capture when i ran two instances of this app it throws exceptions like camera is already in use.I having a requirement that the same camera will be shared by two Applications.

Is it possible to acheive this using any filters

Thanks in advance

DirectShow web cameras are typically exclusive use resources, applications cannot share them. One solution is to use a virtual camera software that creates a virtual device available to many apps, backed by real devices. Or, you can also implement the sharing yourself.
