0001-dshowvideosink-use-CoInitializeEx-for-multithread-su.patch

Current implementation uses CoInitialize and doesn't integrates well with
GStreamer's thread. 
An example is setting the element to NULL and back to PLAY. It will stop on
::start() trying to create a new instance of a direct show grap:
"Can't create an instance of the dshow graph manager (error=8000ffff)"
Using CoInitializeEx with COINIT_MULTITHREADED fixes this issue and allows to
implement preroll using #579926.
