GL_NV_vdpau_interop output_surface alpha component
 
HI,

I'm using vdpau_interop to get output_surfaces in gl textures.
When GL_BLEND is enabled, nothing shows on screen, when it's disabled the video texture is visible. So i've made a simple shader to read video texture alpha component, and indeed it's set to 0.0
Is this expected ?
