I did some tests earlier this morning and apparently the input switching is done through some stk1160 GPIO port setting. However, I'll have to figure this out reading easycap staging driver and trying different values over and over. Plus, saa7115 driver supports "s_routing" function, but couldn't make it work: it looked like saa7115 input setting was fixed and stk1160 handles the input switching. Also, I'm not sure if saa7115 "s_stream" to enable/disable capture is also working. Sounds a bit weird to me. One last query: I found *no* way to distinguish between one device (one composite input) and the other (four composite input). What do you suggest? Just implement all of them always? Looks like I'm on the right path anyway :) Thanks, Ezequiel. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
