My Logitech QuickCam is now working under both 64 Studio and JAD, but it
was not an especially pleasant experience to get it going. Since both
distros had exactly the same issues I thought I'd ask what problems the
maintainers face when considering support for these cameras.
The first and biggest problem is that there's no /dev/video nodes and
they were not automatically created by udev or anything else. I was a
bit surprised at how much digging I did before I realized that I simply
had to create that node. Once that was done (with mknod) then I could
try my camera with the videodev and uvcvideo drivers. At that point I
could plug in the camera (it's a USB device) and get some results.
It works, but not with everything. Xawtv4 and luvcview both work (with
YUV format, but not MJPG), xawtv does not, nor did any other grabber I
tried. Either the camera never initializes or I just get a blank display
window. I'm still working on why that happens. I'm also confused about
how to improve the frame-rate. Apparently the grabber software ignores
my indication for a faster rate, even though the camera explicitly
supports up to 30 fps. Alas, I don't know if that's an input or output rate.
I also tried some apps that utilized the gspca driver, which is also
supposed to work with my camera, but I got no joy from any of them. If
they start they segfault almost immediately, with little or no helpful
I'm still trying to get Veejay, FreeJ, and Gephex to recognize the
camera. FLxER knows it's there but I haven't figured out how to make it
work in the program. I also want to see if I can send a live feed into
The domain is potentially confusing for novices. V4L, V4L2, and the
apparently overlapping drivers made for a bit of bewilderment on my
part, and I'm still trying to make sense of the situation. I'd love to
hear from anyone else using a webcam with 64 Studio or any other system,
and I'd especially like to know if anyone has got a camera working as an
input device for the programs mentioned above.
Anyway, that's my little report.
