Hi,

I created a background plugin with the Windows Media Player 10 SDK in order
to capture the mouse movements and keystrokes of the media player or to be
more precise of the mouse movement over the video window. But the events are
never sent through to the plugin. Am I right to assume that this is on
purpose?
Is there another way for me to capture these events via a plugin or do I
have to capture these manually from an outside application and hooking to the
message queue of the VideoWindow?

Thanks and regards

The only way I have been able to do this is to actually hook the windows
proc... The most challenging part is to actually find the desired
window. Spy can help characterize the window parent hierarchy for you.
Also be aware that changing views in WMP often destroys the window of
interest so you often have to monitor for the presence of the window and
unhook and re-hook it when it reappears.

Thanks for your help,

what you describe seems to be the only viable option for handling user input
over the video window. I think you can get a handle to the video window by
querying the IVideoWindow interface from the DirectShow graph and calling
get_Owner() on that interface.

But the problem is how can we get the IVideoWindow from Windows Media Player Plugin?
