问题
Thi is my filtergraph. when I run the graph, I don't see any video window. But, If I replace the EVR with some other rederer (VMR7, VMR9, etc.) I get the video window. Kindly Help.
Are there some changes to filtergraph needs to be done? Moreover, I can't find any AVI Decoder, where can I find? Any recommended codec pack? for Windows 7...
