[gst-devel] How to temporarily disable drawing in the directdrawsink?

I'm not sure about directdraw, but in direct3d if you've lost the d3d device object (due to another app going to fullscreen, a UAC prompt, etc.), then incoming frames won't be drawn until you reset the device and redraw. Directdraw may have something similar.

I think he his asking "how", and not "why" :P

The approach might vary depending on the pipeline you are using, but
usually setting the element to the paused state, locking its state and
unplugging it will do the job.
