Hi, I have been using graphedit on Windows for testing some two streaming interface device for a while. Although I did not find any application that uses two UVC streams. The graphedit will just provide any number of pins for the number of streaming interface you have. You can test each of the pin individually or test them altogether. By the way for the UVC device developing side I found the Null renderer in DirectShow filter is very helpful for verifying the device. I am wondering if there is anything similar on Linux side?
