Feature Request: Support of uvc devices using uvcvideo

Description

It would be very nice if motion could support uvc webcams. Trying a Logitech Pro 5000, supported by the new ( unfinished ) module uvcvideo, results in the following error from motion:

Apr 9 10:04:45 ds motion: [1] ioctl(VIDIOCGMBUF) - Error device does not suppor t memory map Apr 9 10:04:45 ds motion: [1] V4L capturing using read is deprecated! Apr 9 10:04:45 ds motion: [1] Motion only supports mmap Apr 9 10:04:45 ds motion: [1] Capture error calling vid_start

luvcview works fine with the camera on FC4 2.6.16-1 I am not sure whether this is a problem in uvcvideo or motion ( or both ).

Follow up

A closer look at the code reveals that uvcvideo only supports V4L2, so aparrently its just a matter of time before motion supports this driver...

Comments

I totaly agree, as more and more webcams come out, uvc will be the only way to, especially for Logitech products(the biggest seller of webcams worldwide)

Current V4L2 patch already support cameras with uvcvideo that uses YUYV palette.

Look that support question answer :

I'm using the latest SVN code refreshed today (13th Feb 2007). I have a Logitech Sphere using the latest uvcvideo code (from SVN) which works fine in both xawtv and kdetv.

I'm getting the following output:

Could you tell me what is the output of lsusb command for your camera ?

It should be some that are listed here http://linux-uvc.berlios.de/

# lsusb

Bus 001 Device 002: ID 046d:08ca Logitech, Inc.

-- AngelCarpintero - 13 Feb 2007

Bus 001 Device 003: ID 046d:08cc Logitech, Inc.

However, I felt like it defeated me so I deleted everything, motion/uvdvideo and downloaded the source again and built from scratch. It works!

I do have one small issue, which is that the live webcam server on port 8081 just shows up as a black screen, but the images captured during motion detection are clear as crystal. I'll keep looking into it for a while and raise a new issue if it's nothing obvious.

Unfortunately I'm experiencing exactly the same problem as PaulSmith, but this time with a Logitech Quickcam Pro 5000. Here is the output from lsusb:

Bus 005 Device 002: ID 046d:08c5 Logitech, Inc.

And the output from Motion (svn r172) with uvcvideo (svn r89):

FYI - the camera works fine with LUVCview so I'm guessing it's not a driver issue but a problem with Motion?

I've tried motion with that camera and motion worked without problem, not sure what could be the problem ... maybe some "race condition" , please post your motion.conf file, because i guess that some parameter makes motion to fail.

-- AngelCarpintero - 05 Mar 2007

Thanks for the quick response. I have attached my current configuration file. It should be fairly standard as I didn't want to touch too many options until I knew the standard configuration worked ok.

Logitech Quickcam Pro 5000 works fine with current svn version on my gentoo with kernel 2.6.19-r5
