Greetings; Needing a decently decent resolution but tiny camera, suitable for mounting on my cnc machines to give them some machine vision, I came across some cheap ones that claimed over 1000 tv lines, for less than 8 bucks USD. Since the last one of those was $22 and was about 10% the size of this one, worked well till an errant hold down bolt sticking up from the mills table ran thru its space and knocked my custom made mount into the next drainage, so at <8 bucks a copy, if it worked, I bought 4 as to have spares.
They arrived today, and since I had used cheese to see it they worked before, I did a "sudo apt-get install cheese" which pulled in just shy of 25 megabytes of libraries etc etc. Now I have 25 megs worth of stuff that does nothing but segfault on this wheezy install: [1154154.821607] cheese[4139]: segfault at 0 ip 00000000f6b8aba8 sp 00000000ffd1354c error 4 in libc-2.13.so[f6b13000+15e000] Positively luverly. Called up synaptic and had it install all the v4l(1/2) related stuffs. But all it can find is my pcHDTV-3000 cards cx88 video source, which I assume works because kaffein does too. So I unplugged it, and replugged it to get a fresh snapshot in dmesg, as follows: [1154216.679583] usb 1-4.2: USB disconnect, device number 12 [1154220.971847] usb 1-4.2: new high-speed USB device number 13 using ehci_hcd [1154221.140476] usb 1-4.2: New USB device found, idVendor=1908, idProduct=2310 [1154221.140481] usb 1-4.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [1154221.140484] usb 1-4.2: Product: USB2.0 PC CAMERA [1154221.140486] usb 1-4.2: Manufacturer: Generic [1154221.140488] usb 1-4.2: SerialNumber: 20100331010203 [1154221.140892] uvcvideo: Found UVC 1.00 device USB2.0 PC CAMERA (1908:2310) [1154221.141566] input: USB2.0 PC CAMERA as /devices/pci0000:00/0000:00:02.1/usb1/1-4/1-4.2/1-4.2:1.0/input/input14 There is no /dev/input/input14. There is a /dev/video1 created just now. Trying to open /dev/video1 with kaffeine gets me an advisory reporting the failure: 03:25:19 PM: xine: couldn't find demux for >file:///dev/video1< 03:25:19 PM: xine: found input plugin : file input plugin 03:25:19 PM: video_decoder: can't raise nice priority by 1: Operation not permitted 03:25:19 PM: video_out: can't raise nice priority by 2: Operation not permitted So, how do I go about seeing if this camera can be made to work with "camview" and friends on my lathe & milling machines? The dmesg output looks as if its a valid device. Many Thanks for any assistence in this. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
