That is crazy! Who created such retard API?? In both cases you are going to show video from /dev/video6 device. But in real I have two independent camera devices: front and back. Why on the earth I cannot have /dev/video0 for back camera and /dev/video1 for front camera? And need to call such huge commands which re-route pictures from correct camera to /dev/video6 device? I'm really not interested in some hw details how are cameras connected, I just want to show pictures in userspace... And what are those others /dev/video[0-5] devices? -- Pali Rohár pali.rohar@xxxxxxxxx -- 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
