VMR Dynamic reconnection

Question

Hi !

I have an application with many graphs that acquire & process video samples.

I am using a computer which has a bad video card, that's why I don't render any graph with a vmr.

Sometime I would like to display one graph without stop this graph. So I am looking for a way to dynamically reconnect the graph with a vmr.

I saw that I should have a filter that implements the IPinFlowControl interface on its output pin. So I think that I must end my graph chain with a custom filter that implements these interface on its output pin.

What is the best method to do this ? do I have to make a transinplace filter with the IPinFlowControl on its output pin ? in this case do I have to force this transinplace to use different allocators ?

Any suggestion will be great, thanks.
