Webcam - motion not working - but video ok on mplayer

[piglet]

I read about "motion" being used by someone else on the forum and thought I'd have a try connecting my Logitech Clicksmart 510 webcam.

sudo apt-get update
sudo apt-get install mplayer
mplayer tv:// driver=412:width=640:height=480:device=/dev/video0 -fps 10

Success - video across the screen.

However when I did:

sudo apt-get motion

(edited motion.conf for same resolution as worked above, and format JPEG)

sudo motion -n

couldn't drive the camera (full details of output below).

[1] v4l2_next: VIDIOC_QBUF: Invalid argument
[1] Video device fatal error - Closing video device
[1] Closing video device /dev/video0

Do you have any idea how to get it working? I don't see any error that I understand.

Thanks in advance

I guess nobody knows

[Bencom]

I do not know but...

I have a similar issue. Give me some time and I will post more.
My camera was working for a week or so and then a bug was introduced.
This bug is in the kernel or a module.
My camera works for a period until the first error happens.
Eventually it causes motion to time out.

We can not resolve this. We need to get the issue in front of those with an understanding of the kernel drivers.

My camera Genius FaceCam 1020 which uses the uvcvideo driver. Running fully up to date Raspberrian Wheezy.

[Bencom]

I think under load something is falling over.
As well as streaming video I want to stream audio.
I can do this with avconv via rtp and play vid and aud in a vlc session.
When I run avconv the errors consistently appear although the error still occurs sooner or later if I do not run avconv as well. Eventually motion crashes then more errors are noted.

My log.

Just chiming in with a "me, too" on this problem.

Just got my RPi up and running. Using Arch. Installed motion. Webcam loads and runs fine for a minute or 2. Then it appears it freezes. Which is to say, it shows an image but it doesn't show any change in the video frame. Then it conks out with these messages in /var/log/errors/log:

Are you able to establish what driver your camera uses? UVC?

I am reading kernal code tonight

[whatshisname]

Yes. uvcvideo is the driver I'm using.

Thanks.

[bblood]

I can verify the instability of uvcvideo...my rpi is headless I am running motion and get the watchdog timeout....graceful restart every couple minutes. This is something that seems to have cropped up recently...

Camera is logitech quick cam pro 9000. Distro is wheezy...very frustrating...I can't provide logs...i am on an iPad and can't figure out how to cut and paste from vSSH app....also very frustrating....

Hello, just a suggestion. For webcams using uvcvideo module, there's an intersting program to test your webcam. The name is luvcview. It's on Raspian repo: sudo apt-get install luvcview. Run luvcview -h to know its options. It helped me to setup motion with my super cheap chinese webcam. Today tested 5 hours motion run, with no issues. luvcview helps to determine the best ratio between /fps/size/ and motion usability. For example my cheap webcam should support 640x480 x 30 fps. On raspy I have to limit the size to 352x288 and the fps is limited automatically to 5 fps. Warning: if you launch luvcview and for some reason you get a black screen, then the program window *can't* be closed by window manager. CTRL+c in terminal you used or xkill. But before anything else : luvcview -h.

[bblood]

Thanks for the suggestion....my rpi is headless....but, my webcam is on the confirmed list, and, it was working perfectly up until recently....not sure which firmware update killed it. I have had to shut down motion until the fix comes out. I have another webcam I will try when I get home...it is also uvcvideo, but much, much older.

[relnext]

Having the same problems here also. Motion seems to time out after 3 or 4 minutes. Have a Logitech C270 plugged into a powered hub. Camera works continuously with other software. Be nice to hear of a resolve to this issue.

[ahagadgets]

For us it worked (for the time being) at a low frame rate and resolution.

Effectively: luvcview -s 320x240 -i 1

(oh btw, our webcam is a super cheap chinese "snake" brand cam, which uses uvcvideo driver. We've been swapping kernel/fs images like crazy all through last week till we realized its a driver problem )

[relnext]

i've currently switched to mjpg-streamer and it keeps the connection for longer periods. still not 24/7 by any means. i'm interested to see what will happen when the camera module is released. the kids want to stream our rat-cam for the world to see.

[whatshisname]

relnext,

Here's what one guy did to get your webcam working with motion:

Code: Select all

I have it running on an Arch install (soft float) with a Logitech C270 webcam. However, it did take a bit of fiddling with quite a bit of trawling the web (mostly archlinux wiki). The steps below worked for me but I haven't fully got to all of the reasons why quite yet:
1) installed via standard $ pacman -S motion
2) changed a few settings in the ~/.motion/motion.conf file
   - v412-palette 6
   - ffmpeg_video_codec swf   (mpeg4 didn't work)
   - framerate 10      (probably could be better, haven't got around to tweaking more)
   - other local changes like target directory
3) had to make /dev/video0 visible via a udev rule /etc/udev/rules.d/10.local.rules containing
   KERNEL=="video[0-9]*", MODE=="0666"
4) prior to running motion each time had to reload the uvcvideo module with
   - $ sudo rmmod uvcvideo
   - $ sudo modprobe uvcvideo
5) then run motion with $ LD_PRELOAD=/usr/lib/libv4l//v4l2convert.so motion -s
6) these 3 commands were then added to a bash script for simplicity
cheers
Rob

I tried what Rob did with my Logitech C260 but I still couldn't get motion to stay up longer than 5 minutes before it crashed and burned.

I decided to throw in the towel on the C260 and bought a HP HD-2200 which is supposed to be compatible with the ARM chip.

So far success. Motion has been up for an hour with no problems. I'll report back later on how long this lasts.

[shuckle]

I am interested if you get good quality picture from your cam?

[cupcake]

I was sent to this thread from my issue described here (link).

Is the general consensus that webcams are problematic with latest Wheezy?

[rivalcomp]

Just for feedback my Logitech QuickCam for Notebook Deluxe doesn't work with motion.

And after this a lot of "Corrupt JPEG data: premature end of data segment" messages. After a variable interval motion restarts /dev/video0. Some frames comes through (1-2 frames/sec) but they are corrupted: the whole frame is visible but it is black and white with a lot of smudged colors in it. Tried with different resolutions, framerates, no luck. Someone on the internet suggested recompilig motion source with the error message commented out. I don't think this should be the ultimate solution, because camera can't provide useable video.

Is there any way to force an other driver (if there is)?

[rivalcomp]

Forgot to mention I'd like to use this camera on a self powered USB HUB (5V 1A). RasPi has it's own 5V 1A power supply.

[ahynes1]

I'm running a headless RPi with a Logitech 9000. I had similar problems.

Looking through my messages, I found:

[1] Config palette index 8 (YU12) doesn't work.
[1] Supported palettes:
[1] 0: MJPG (MJPEG)
[1] 1: YUYV (YUV 4:2:2 (YUYV))
[1] Selected palette YUYV

So, I tried changing the palet to be MJPEG
>>> v4l2_palette 2

All of a sudden it started working. I could even run higher resolution. I pushed it up to 1024x768. I still got a few errors, but mostly it worked even at this level.

[johnsonfamily38]

Im running wheezy with motion 3.2.12 and a logitech Webcam C100 and had similar setup problems.
I had to change to "v412_pallette_6" to match the camera output, but it still occassionally losses the thread to the /dev/video device. The http server then stops.

One workaround was to re-start the motion process by adding the following line to the susers cron table:

30 * * * * sudo pkill -9 motion; sleep 5; sudo motion;

This works fine, restarting every 30 mins.

[wheezer]

SOLVED:

I am running a Logitech C525.

I was running motion as a daemon with: sudo service motion start

I could load a webpage and the image was fine but after a few minutes OR if I "moved" in front of the camera the camera would turn off immediately and I would get in "/var/log/messages": Closing video device /dev/video0

Here is the reason why. I had modified a thread1.conf file to write all captured .jpg/.swf files to a directory of my choosing, not the default /tmp. When the camera attempted to write the "motion capture" files the directory which I had created had the wrong ownership. The capture directory needs to be owned by "motion: motion". So if your "target_dir" attribute is "/motion_capture_directory" then "chown motion:motion motion_capture_directory" - no quotes. Now
motion is working fine for me and I am looking at it in 640x480.

Maybe this is the cause of your problems. If your have your config files under different users then the base install then you need to be careful with permissions and ownership. The best thing is to run it in its default configuration. That way if you start changing target directories, etc. and it fails you will know why.
