Hmm errm, I said VLC would need to be able to match a V4L2 device to an ALSA input (where applicable). Currently, V4L2 devices are enumerated with (lib)udev though. I am not very clear how v4l2-utils fits there (and oh, ALSA is a bitch for udev-hotplugging but I'm getting side tracked). I guess I misunderstood that /dev/media would logically group related devices. Now I guess it is _solely_ intended to plug DSPs together à la OpenMAX IL.

Should it be exposed as a udev device attribute instead then? -- Rémi Denis-Courmont http://www.remlab.net/ http://fi.linkedin.com/in/remidenis -- 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
