Sounds more like a question for the people who make the capture card.

Hi James, I'm contacting you because i found one post on the msdn forum by you, the one about the driver files : CG300vc.sys, CG300AU.SYS, KUTILS.SYS, VGACard.sys

I'm trying to access video from them via directshow but they don't show up anywhere! Do you know if the Star Imavision (CG300) driver uses some other proprietary interface to communicate with the driver?

I look forward to seeing your reply

You will need to synchronize all 4 inputs to the same timing in order to reduce the sync delay but depening on the board design that may not change anything either. The video capture will take at least a frame to sync up to the different video signal when you switch.

Hi,Douglas Jordan . how to synchronize all 4 inputs to the same timing by directshow ?

i use IAMCrossbar::Route to change the video signal , i can get the video's data but this switch use about 1 second .

I shoudl have stated - synchronize the 4 inputs externally with other hardware. DirectShow does not have this feature.
