Hi everyone, I don't know how to use two filtergraphs simultaneously in my application. When I build two identical filtergraphs to capture two video sources simultaneously, it works fine when the two filtergraphs run at the same time. But at the time when I stop them, the application cracks. Each of the filtergraphs can run and stop properly if the other is stopped. Does anyone have the same experience as mine? Please help me solve this puzzle:) thanks. :confused:
