[Linux-uvc-devel] Debugging UVC + Sanyo Xacti cameras
Hi Laurent and UVC developers, I'm starting to give a close look at luvcview failures when using Xacti cameras with UVC. I'm new to UVC so any help would be greatly appreciated. The problem was initially described by Lars Täuber with the Sanyo HD 1000: http://lists.berlios.de/pipermail/linux-uvc-devel/2007-September/002145.html To summarize: luvcview works on the first execute-quit sequence but fails if you try to execute luvcview again. I tried plugging Lars Täuber's code snippet into uvc_driver.c but that had no visible effect. I'm experiencing the same problem with a Xacti C6. I also have access to Xacti C4, HD 1000, and HD 2 cameras to test on other models. Device numbers: Xacti HD 1000: 0474:0238 Xacti C6: 0474:0241 Below are logs obtained with SnoopyPro-022 while starting AMCap video capture on Windows XP ( http://noeld.com/programs.asp?cat=video ) These logs track the following sequence: - Start Amcap - Capture 2 to 3 seconds of 320x240 video - Quit Amcap - Wait a few seconds - Start Amcap - Capture 2 to 3 seconds of 320x240 video - Quit Amcap Log from video device: Snoopy binary log: http://www.ailab.ch/~tnetter/USBLog12.usblog Text version: http://www.ailab.ch/~tnetter/log12.txt.gz Simultaneous log from composite device: Snoopy binary log: http://www.ailab.ch/~tnetter/USBLog13.usblog Text version: http://www.ailab.ch/~tnetter/log13.txt.gz Here's what happens in Ubuntu 7.10, linux 2.6.22-14-generic, uvcvideo-r104, luvcview-20070512 (tried both from SVN and from deb package).

I just purchased the above-mentioned camera and went through a few different drivers trying to find one that would recognize this camera before finding uvcvideo. That seems to work but now when I run luvcview I get a black picture. Actually its just very dark as I discovered when I pointed it directly at a light. I tried cranking uo the brightness and the contrast but I cannot seem to get a picture out of it even in full light. Does anyone know what I'm doing wrong? When pushing brightness up, do you see any change in the image ? Do you get error messages in the kernel log ? You could also try your luck on the www.quickcamteam.net forums.

Re: [Linux-uvc-devel] is there any device side code?
Hi Brian, On Sunday 16 December 2007, Brian Pin wrote: Hi, I am wondering is there any linux/open source device(gadget) driver for UVC now. Is it highly device dependent? Thomann Andreas posted a mail to the list on September 15th 2006 and seemed to imply he would start a UVC gadget driver. You should try to contact him. Another question, an UVC driver should open its sof interrupt, is it true? Because if it doesn't, it won't be able to handle isoc packets on time and could possiblly lose packets. I am asking this because I am on a very low cpu clock environment, my system can't handle sof interrupt that fast. So I am must turn off sof interrupt. Anyway, no matter host/device mode UVC always need to handle its sof interrupt right? UVC devices must report the SOF counter value, but I don't think they need to process SOF interrupts if the device has a hardware SOF counter.

I added a few lines in the input_uvc module so as to turn off auto-exposure, gain and whitebalance, but no combination of this seems to work. The following code: printf(Auto whitebalance: %d\n, v4l2SetControl(vd, V4L2_CID_WHITE_BALANCE_TEMPERATURE_AUTO, 0)); printf(Auto exposure: %d\n, v4l2SetControl(vd, V4L2_CID_EXPOSURE_AUTO, 0)); printf(Auto gain: %d\n, v4l2SetControl(vd, V4L2_CID_AUTOGAIN, 0)); results in: contol White Balance Temperature, Auto unsupported Auto whitebalance: -1 I don't know why this fails. Could you try modifying auto white balance only and check the kernel log for error messages ? You can set the trace level to 4 for additional control-related information. Auto exposure: 0 No problem there. Auto gain: -1 Auto gain is not supported by your camera, so this is expected. dmesg output: uvcvideo: Failed to query (1) UVC control 2 (unit 2) : -32 (exp. 2). Have you tried modifying the brightness ? control 2/unit 2 is the brightness control. uvc module revision 156, device id 046d:08ce, Am I missing something?

The rest of the image will be shifted. i searched a lot and found a little help on the quickcam team page, but the hints are dated from 2006. is this still a bug? When bandwidth is not involved, this kind of problem can be caused by bad USB cables, or noisy electrical environments. Making sure your USB cable doesn't run too close to power cables might help.

The problem is not Ubuntu-specific. I *think* it is unfortunately device-specific. The device failed to answer two requests. The first one (135) is a very common device bug that the driver works around. The second one seems to be another device bug that the driver can't work around :-/ Basically, the driver queries the device, and the device stalls (refuses to answer the request). As this doesn't happen everytime, I suspect the problem to be caused by a firmware bug in the device. It might be possible to implement a software workaround in the UVC driver by adding a small delay in one place or another, but I don't know of any definitive solution. The device passed manufacturer's testing because Windows and Linux schedule USB transactions differently, which results in slower timings in Windows. The bug just slipped uncaught. It might also be possible to tweak the EHCI controller driver to alter timings and make them more Windows-like. That would be a complex project, involving deep knowledge of the EHCI host controller. The documentation is out there though. Best regards, Laurent Pinchart ___ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel

Re: [Linux-uvc-devel] New Camera Feiya Technology 090c:b370
It turns out that the GET_DEF wasn't causing the original error at all. The old Ubuntu version of uvcvideo must be doing something different. So I'm now running the unpatched code I grabbed from svn earlier today and I've got it kinda working. luvcview -f yuv works, and once I figured out that there was a channel 0, I got ekiga working too. The one program I wanted to use though, kopete, still sends errors to syslog and somehow crashes the camera too. I'll play more tomorrow.
