Hi all, as of late, i have purchased the brand spanking new web cam, Quickcam pro, finding out in lost hope that it is unsupported by the traditional drives, my hopes are lifted with this project! :) anyway. I have compiled all that is needed for the webcam to work, and loaded all the modules and what not, and can even see myself with uvcview utility. However, currently, i cannot use it as i intended with aMSN, while at points, tries to work (indicated by the flickering of the camera, and apparently slow process) but fails to work. also, xawtv, mplayer, and others also fail to see the video. I suppose my question is this, is there any possible way to output the captured stream of uvcview to another v4l device, so as to provide a more reliable method of video output. Im sorry if my question is foolish, i am not well versed in v4l2 or this project. And my C[++] needs updating no doubt. Perhaps more clearly, my question is why is it uvcviewer can see it properly, where as applications using the standard v4l2 cannot, and how, if possible, can we make the output more standard, as to be seen by the standard programs, like xawtv, and such. Also, i would like to know, if needed, what could be done to further aid the development of this project, i am willing to attempt to learn v4l2, and relevant USB2 information to possibly help in advancing this project, although as of now, no promises can be made (working highly odd hours, unreliable hours really). Also, heh, sorry for this message, as i have spent the last 12 hours or so working at a computer, my brain is somewhat less than optimal. so please excuse the poor grammar, punctuation, run on sentences, etc. I dont know if dmesg outputs are relevant, but if they are, i shall post them (didnt want to fill this post with nonsense) Tanner |

Hi. I\'ve tried the patch which applied and compiled nicely. But i get. Could not set webcam to 128x96; got 160x120 instead. mythfrontend: symbol lookup error: /usr/local/lib/mythtv/plugins/libmythphone.so: undefined symbol: _ZN14MJPEGContainerC1Ev I made distclean, so i dunno. Seems like im missing something.. /Br Fredrik |

Anyway, i can help to test a driver... Still image capture ? What do you exactly mean ? The USB Video Class defines several methods of still image capture. The one supported by the Logitech webcams is simply to capture the next image in the stream when the button is pressed. The camera button is supported by the driver, but it currently does nothing. Is that what you need ? Laurent Pinchart |

Something else seems wrong here... The offset of the second buffer is equal to the length of the first buffer, so you probably ended up unmapping the second buffer four times. It's fixed anyway :-) Laurent Pinchart |

Ok, I created a small test program, and came to the conclusion that it was another bug in my code. Doh. I was passing in the wrong second argument to munmap(). Interestingly enough, given that I was passing bad information to munmap(), it was still succeeding 3 out of 4 times... Something else seems wrong here... -- Nick --- ynu...@ya... wrote: > Actually, part of the problem was a bug in my code. > OOPS. :) I'm still seeing other problems trying to > munmap() memory, but I haven't had time to create a > reproducable test case...

Hi I'm trying to use Logitech Fusion camera (which has outstanding video quality ) as Linux web-cam server... Driver is working Ok, but there is one thing that is requred for usage as surveillance solution - it's a still image capture support... Is there any plans for implementing it? Maybe some timeline? Anyway, i can help to test a driver... ------- Thanks, Max Shaposhnikov e-mail: sh...@ma... icq: 273777 home page: http://shapa.maxnet.ru cell phone: +447798720657 satellite phone: +8821653300761 If life is a stage, I want some better lighting. |

Actually, part of the problem was a bug in my code. OOPS. :) I'm still seeing other problems trying to munmap() memory, but I haven't had time to create a reproducable test case...

I submitted the patch to the mythtv developers. http://cvs.mythtv.org/trac/ticket/1051 It looks like they're targeting a 0.20 release, which, given mythtv's release schedule, will probably be in 2 years. :( -- Nick |

I have to work on frame rate issues, there are probably a few problems left. What frame size did you select for capture in Linux ? 1024x576 and 1280x960 use an uncompressed format which needs a much higher bandwidth than smaller sizes. > I tryed to use camorama but it fails to open the /dev/video1 device. > What's the issue ? > Should it just be compatible if there is a video device in /dev ? I haven't checked camorama, but the UVC driver only support V4L2 (V4L1 is deprecated), and doesn't support the read() method yet. That's probably why camorama failes. Laurent Pinchart |

Hi Nick, > Please find attached a patch to MythTV / MythPhone to > support MJPEG and UVC. This patch should apply > cleanly against Myth SVN version 8626. Thanks. > Some outstanding problems / concerns with this patch: > > 1) The webcam does not turn off when exiting out of > mythphone.

It should turn off when the device is closed. Could you please have a look at dmesg and see if either VIDIOC_STREAMOFF or uvc_v4l2_release are printed when exiting from mythphone ? > 2) There's a complete lack of testing for other camera > types besides the Logitech Quickcam Fusion. The other Logitech UVC webcams will work too (except maybe the Quickcam Pro 5000 which is a bit different, but it shouldn't matter too much) as they all have the same hardware/firmware. > UVC folks: I would appreciate it if you could add > this patch to your collection. Hopefully soon, I'll > be submitting it to the mythtv folks. I want to wait > until my problems shutting down the webcam are solved > first... Applied. Please try to submit it to mythphone, at least to have their opinion. Your patch adds V4L2 support but removes V4L support, I'm not sure the mythtv developpers will be very happy with that (but I might be wrong, and I certainly hope so, V4L is deprecated anyway).

The frame rate is better on windows too, but I guess it's because there is compression on the signal. I use a USB 2 powered 8 ports HUB. I tryed to use camorama but it fails to open the /dev/video1 device. What's the issue ? Should it just be compatible if there is a video device in /dev ? |

So the problem is that the module is installed in
/lib/modules/2.6.12/usb/media/
instead of
/lib/modules/2.6.12-10-k7/kernel/drivers/usb/media/
The Makefile is below just before there is a make plus a make install.
