Is this also required for ozone? The comment below seems to be very
Windows-specific.

[llandwerlin-old, 2014/10/08 09:31:18]

Yes, Ozone needs have a UI type thread too. I will modify the comment.

   // For windows the decoding thread initializes the media foundation decoder
   // which uses COM. We need the thread to be a UI thread.
