Re: Capture Graph with VMR9 in Windowless mode

it's on my list to look at when I have some spare time. However, in this
case I think you would be ok using the bridge. The graph containing the
renderer is stopped -- but you would have the mux and file writer in a
separate graph which is therefore not stopped. You can handle the
renderdevice-set event by stopping and restarting the source graph or
whatever, and the mux/writer graph will continue ok.

Thanks for the assistance Geraint. I have to keep the support
in-house so I can't use the GMF Bridge. If it's of any interest to
anyone facing a similar problem, I've put the following work-around in
place:

Use CancelDefaultHandling onEC_DISPLAY_CHANGED, added an handler in
my app, detach the currently open file, then unbuild and re-build the
graph and re-start capturing.

Thanks for posting your workaround. I've also seen this problem in my
application and after implementing your suggestion the
EC_DISPLAY_CHANGED message is posted again right after I re-start.
It's like the event wasn't cleared or something even though the entire
graph was unloaded and reloaded.

Has anyone else seen this behavior?
