Logitech Quickcam cool using spca5xx-le driver

Question

My motion is running in a Asus router with OpenWrt whiterussian 0.9 firmware. I want to connect Logitech Quickcam cool using spca5xx-le driver. (The original spca5xx driver do not support this cam, I need to modify the spca5xx driver). The cam work with spcaserv & spcaview (the driver's companion tools) but fail with motion. It seems motion cannot find a usable palette. Is this problem of motion or the spca5xx driver ? Many thanks!

Answer

Please upgrade to at least to 3.2.9 , but probably the problem is related to your driver.

Thanks for your prompt reply. I had tried cross compile motion 3.2.9 under OpenWrt buildroot, but not yet success.

For the problem, I had tried another webcam, Creative NX pro. When use the same spca5xx-le driver, it has the same problem. When use the full version spca5xx driver, it work with motion. The spca5xx driver use another palette other than 21 that the spca5xx-le photography for sale use.

Aren't motion support palette 21 ? (I am sorry that, I don't quite understand the palette here !)

For the Logitech cam, I can make it work in another way. I use spcacat to save a jpg file every 0.5s, then motion use "netcam_url http://127.0.0.1/tmp/SpcaPict.jpg" as source. Is there any smarter way to make it work ?


According to http://mxhaard.free.fr/spca5xx.html :

Logitech  QuickCam Cool  0x046d 0x08ac Jpeg spca5xx/LE  gspca v4l1/v4l2

So you need mjpeg support , take a look to ./configure output :
 mjpeg Support:       Yes
