Hi everyone,
I have Logitech Quickcam Orbit/Sphere 1.3MP and installed ZoneMinder 1.24 build 2679 (ZoneMinder-1.24.0-rc1-2679.tar.gz) on CentOS 5.2.
After overcoming all compile problems (ZoneMinder did not want to compile because of missing ffmpeg packages since default ffmpeg installation did not add them - solved by looking at those forums) - I experience the same problem as described in the above post (the image from V4L2 camera is wrong palette). In addition, the CPU load while I monitor this webcam jumps considerably - a process called "nph-zms" consumes up to 50-70% of the CPU.
Has anyone been able to solve this wrong palette problem? The high CPU load is also an issue for me since I try to build a surveillance system based on a small PC with performance close to thin client. I need to use it with 3 cameras and if this is what happens with one camera, the load for 3 cameras will be probably at 100%. I doubt that I am doing everything correctly, since I heard of people who were able to run ZoneMinder on OpenWRT-based routers, which can offer about 1/2 or 1/3 of the performance of my small PC.
So after this long explanation, here are my specifications:
Hardware
Computer - Fit-PC Slim
http://www.fit-pc.com. CPU: AMD Geode LX 800 - 500 MHz. RAM - 512MB. Hard disk - 2.5" SSD IDE Transcend MLC (TS32GSSD25-M)
Camera - Logitech Quickcam Orbit/Sphere 1.3MP (2006 version)
Software
OS - CentOS 5.2 text-only support (no GUI). It was a bit tricky to install CentOS 5.2 on this PC since it does not install there on itself. Anaconda (CentOS installer) thinks that this CPU is not able to execute i686 instructions, so it crashes during installation. On the other hand, there is a workaround by plugging the hard disk of this PC into a PIII laptop, installing CentOS 5.2 there, and then moving the hard disk back to Fit-PC. This also worked for me. The reason I chose CentOS is because I am most familiar with RedHat Enterprise Linux, and CentOS is the free version of RedHat. In addition, ZoneMinder itself was written under CentOS as I understood, so I tried to make the system as similar as possible to the original, to make my life easier with problems solution.
CentOS 4.7 installation is working perfect without any workaround to move the hard disk, but unfortunately Linux-UVC drivers do not compile and do not work under it (at least for me).
Drivers - the linux-uvc driver from CentOS "Atrpms" repository. I tried to compile the linux-uvc driver from their Subversion repository, but did not succeed, so I had to use this RPM.
ZoneMinder - as written above, ZoneMinder-1.24.0-rc1-2679.tar.gz
I also installed a few other UVC streaming helpers like luvcview, mjpeg_streamer etc., to test the camera there, since at the beginning I did not manage to get any output from ZoneMinder at all (not even wrong palette one).
So the outputs from various commands:
