I'm developing an application using a VMR9 Allocator.

The allocator allow me to draw the directshow filter graph output to a texture. I noticed that if I don't use the SwapEffect.Copy in exclusive mode my video rate is bellow 25 (the nominal rate).

I need to use SwapEffect.Discard in order to activate multisampling.

Is there any workaround to use vmr9 allocator with SwapEffect.Discard?

  • Do you have a small sample code? That would come in quite handy. – mrvux Nov 13 '12 at 06:18
  • The code is pretty huge because allocator needs a big amount of code. Anyway I was able to perform this by modifying the vmr9allocator sample in Microsoft SDKs\Windows\V7. Now I have to check against my code to see what is wrong. – Martin Delille Nov 14 '12 at 15:53
