DirectShow - VMR9 Renderer/Graph call for video data 120 times per sec

I have my [pull] source supplying video data for DierctShow VMR9 Renderer, but the problem is - the source is being called for data 120 times per second (!). I guess there is a开发者_JS百科 setting somewhere in DirectShow/Graph/VMR9 that i can adjust to get it closer to normal 30 frames-per-second. Could anyone give me some help on this?

thanks much!

O.

Are you setting timestamps on the data? The VMR will complete the sample and wait for the next one when the timestamp is reached.
