Hiya list, I am running P:D 9.11, installed from the live image via Ubiquity on to a USB key. It really is a great OS :)
However, I'm stuck trying to get a PS3 Eye camera (aka ov534) to work in P:D. In the default install from the live image I was able to get the camera to work in Cheese and Guvcview, but I had no control over framerate etc and when I tried to use the camera in Processing using the OpenCV library I got really distorted images. The camera is supposed to manage up to 125 FPS (which I can get on my Mac!), and there are lots of patches floating around the net to get the ov534 working better in Linux, so I followed the instructions here: http://bear24rw.blogspot.com/2009/11/ps3-eye-driver-patch.html and all seemed to complete successfully and I see the correct info from modinfo. But whenever I try to modprobe the patched gspca_ov534 I get this error: FATAL: Error inserting gspca_ov534 (/lib/modules/2.6.31-9-rt/kernel/drivers/media/video/gspca/gspca_ov534.ko): Unknown symbol in module, or unknown parameter (see dmesg) and dmesg shows this: [ 772.452901] gspca_main: Unknown symbol mutex_lock [ 772.453395] gspca_main: Unknown symbol mutex_lock_interruptible [ 772.453704] gspca_main: Unknown symbol mutex_unlock Now I can't use the PS3 camera in any software at all, and unfortunately it seems to have broken using any other camera in P:D (I get the same gspca_main error in dmesg!). I have tried to do a fair bit of research and I think this mutex lock is related to the rt kernel that P:D uses (but I'm no expert, hence asking here...). My questions are: Has anyone managed to get the PS3 Eye camera working with a patched driver to get high FPS in this release of P:D? If so could you provide some info how you managed it? Does anyone know how I could at least revert safely to the gspca-ov534 that ships with P:D? Would it be worth me trying a generic (i.e. non-RT) kernel? If so, then which one should I apt-get?
