dear members of v4l list I am planning to make a multiple input program with v4l interface. now I can make it work with a one-input pctv card Then I will continue to make a multiple input one. but here it seems I can have two choice. One is a multiple-input card. The other is several one-input card. Then which one is better ? If I choose the first , does it mean I have to use channel change to get different input ? will the channel switch cost much time to lead frames dropped ? I wanna get 25fps in every input . If the choice is the second, maybe it will be easier. I just have a loop . In the loop , I do same thing to every input. But until now I have no experiments. so I dont know whether it can guarantee the framerate too. If someone has experience on this field ,please give you hand . thanks in advance. __________________________________________________ Do You Yahoo!? Yahoo!
