Re: MSI StarCam working in vlc only (with poor colors)
Josef,
white balance temperature and hue controls are being blacklisted in
uvcvideo for all cameras due to a bug in the driver.
A patch fixing the issue was committed recently
(https://lists.berlios.de/pipermail/linux-uvc-devel/2009-December/005396.html)
but I'm not sure when it will be available.
These controls if supported by your camera could help improve the image color.
Best regards,
Paulo

Re: MSI StarCam working in vlc only (with poor colors)
thank you again, paulo, for your off-list help. cam is now working
nicely with xawtv, guvcview and skype. the colors slightly improved
during day-light, when artificial light is used they still look bad
though. i fiddled around with just about all v4l controls but couldn't
really fix it. i'll run a comparison with windows driver when i have a
chance.
for others interested: the fix was indeed the quirks mode. i had to
set it like this:
$ cat /etc/modprobe.d/uvcvideo.conf
options uvcvideo trace=15 quirks=2
regards all,
joe

Re: MSI StarCam working in vlc only (with poor colors)
You must reload the driver,
rmmod uvcvideo
modprobe uvcvideo
otherwise the quirks want have any effect.
uvcvideo is now mantained in the mercurial repo at linuxtv,
installing v4l-dvb will also install uvcvideo, but if you want, just
follow the instructions on the wiki to compile, but use:
hg clone http://linuxtv.org/hg/~pinchartl/uvcvideo/
so that you get the very latest (testing) uvc code.
In any case the quirks should be enough:

MSI StarCam working in vlc only (with poor colors)
Hello dear ML members, I wonder whether you can help me with the following issue. My webcam MSI StarCam (http://www.aaronpc.cz/produkty/msi-starcam-370i) identified as (lsusb) Bus 003 Device 002: ID 1b3b:2951 iPassion Technology Inc. PC Camera/Webcam controller (dmesg) input: Video Bus as /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A03:00/device:1d/LNXVIDEO:00/input/input8 ACPI: Video Device [VID] (multi-head: yes rom: no post: no) Linux video capture interface: v2.00 uvcvideo: Found UVC 1.00 device (1b3b:2951) uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported. Enabling workaround. input: UVC Camera (1b3b:2951) as /devices/pci:00/:00:1d.1/usb3/3-1/3-1:1.0/input/input9 usbcore: registered new interface driver uvcvideo USB Video Class driver (v0.1.0) It is apparently detected while appropriate modules are loaded (v4l1_compat, uvcvideo, videodev), but of 3 tested applications: vlc, xawtv and skype, only vlc shows some output. Moreover there's plenty of uvcvideo: Failed to query (130) UVC probe control : -32 (exp. 26). in dmesg.log. The console outputs of all three programs follow. xawtv: libv4l2: error setting pixformat: Input/output error ioctl: VIDIOC_S_FMT(type=VIDEO_CAPTURE;fmt.pix.width=320;fmt.pix.height=240;fmt.pix.pixelformat=0x47504a4d [MJPG];fmt.pix.field=NONE;fmt.pix.bytesperline=0;fmt.pix.sizeimage=77312;fmt.pix.colorspace=SRGB;fmt.pix.priv=0): Input/output error ioctl: VIDIOC_S_STD(std=0x0 []): Invalid argument skype: libv4l2: error setting pixformat: Input/output error vlc v4l2:// [0xa18a530] main input error: demux doesn't like DEMUX_GET_TIME (probably irrelevant) As I wrote above vlc is able to capture the image but the quality is really low - please see screenshot at http://yfrog.com/86vlcsnap2009120920h48m50p I'd be glad to see the colors improved but main concern is that the camera does not seem to be Skype-friendly. Is there anything that can be done to improve this situation?
