nV News Forums - View Single Post - VdpauDecoderRender() takes unusually long to complete

I came across a post by Stephen where he explained that all vdpau calls are asynchronous. We have returned video surfaces for reuse right after a mixer cycle. Now I tried holding them for another cycle which has changed the behavior.
Is it possible the VdpDecoderRender blocks on a video surface still in use by mixer? If so how can an application know when a surface would be reusable?
