[streamvian]

Now I meet this question.
I want to connect the output pin of file source filter(a MPEG file)and the video capture input pin. When i change the property of video capture input pin same as the property of putput pin file source filter, i still can't connect these two pins.
How can i do this???
help me! Pls.

Well, u sure can.
U just need to get the both pins to agree on the data type while they negotiate it.

There is a callback function for type negotiation (in IPin ) that gets called each time u connect a pin, there u have to return true when the data type match.

If u cant find a compatible data type then u should convert it or give it up
