Installation

• You will need to modify your Cinder build slightly to upgrade to GLee 5.5 which supports the WGL_NV_DX_interop.
  • Copy cinder-src\GLee.c to Cinder\src\cinder\gl\
  • Copy cinder-src\GLee.h to Cinder\include\cinder\gl\
• Make sure you have an up to date video driver. WGL_NV_DX_interop behaves poorly with older drivers.
• After copying/cloning this repo to your Cinder blocks folder, use Tinderbox to create a new project and select to use the Cinder-WMFVideo block as either reference or copy.

Use

The ciWMFVideoPlayer class can be used very similarly to qtime::MovieGl. To load a video, pass a path to the video you want to load to ciWMFVideoPlayer::load. Videos can be stopped, looped, paused and the current position of the playhead in the video can be retrieved or set. Currently drawing videos to screen is a bit different than qtime::MovieGl in that you will have to call the ciWMFVideoPlayer::draw method with a screen position and width/height.
