Hello,
does anyone know if it's possible to get a directshow object to send a WM_PAINT message every time a new frame needs to be rendered? either that, or receive events from an object before or after a frame has been rendered!?
Thanks!!
p.s. i'm trying to draw on top of a video during playback, but i've run the dshow samples e.g. watermark9 etc. but videos don't play back clearly on my laptop @ home so want to use gdi. i think maybe the graphics card isn't good enough!? the strange thing is that it'll play nearly all the d3d samples (presumably using sw device)!?
