My 'ov519' driven v4l2 devices not working

chrisp · Post by **chrisp** » Sun Nov 22, 2009 10:39 pm

Hi All,

I have ZM v1.24.1 installed on my Ubuntu 9.10 Desktop PC (my only hardware).

# uname -a                                 
Linux aphrodite 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64 GNU/Linux

The ZM GUI works fine on http://127.0.0.1/zm (I also added a "cctv" alias) and my intention is to have multiple USB webcams (it looks possible on ZM).

My (2 so far) cameras work individually when I test like this: -

Code: Select all

ffmpeg -an -f video4linux2 -s 640x480 -r 30000/1001 -i /dev/video0 -vcodec mjpeg -y video0.avi
and
ffmpeg -an -f video4linux2 -s 640x480 -r 30000/1001 -i /dev/video1 -vcodec mjpeg -y video1.avi

but they don't both work at the same time. I can also get perfect images streamed from both cameras using VLC (again, not concurrently): -

Code: Select all

vlc v4l2:///dev/video0 --no-video-title-show --no-audio
and
vlc v4l2:///dev/video1 --no-video-title-show --no-audio

Before I found ZM I was trying out webcam-server like this (I created a shell script as I'd never remember the bugfix): -

Code: Select all

% cat FrontCam   
#!/bin/sh

export LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so

webcam-server \
 -c " Front Camera @ %Y%m%d %H:%M:%S %%v viewers at %%f FPS " \
 -g 640x480  \
 -d /dev/video0 \
 -p 8888

I have been reading the 2 following articles (as I found them first, before I installed via synaptic package manager): -

http://www.linuxscrew.com/2007/11/05/ho ... nd-ubuntu/

http://www.howtoforge.com/video_surveil ... der_ubuntu

I have not yet been able to get successful video via ZM and following some unsuccessful googling and searching this forum, I've started to write this post...

Initially I was seeing this in the messages log: -

and this in /tmp/zm_debug.log (I've enabled debug level 9 and it's enormously verbose so I've removed the most boring and repetitive parts): -

This was helped by setting the "Capture Palette" rather than leave it "Undefined", but although I can now get the "Source" line to go orange for a while, it eventually goes red and where once I had black screens instead if actual video images, I now have something which looks like this: -

Additionally, I also get the following error (auth details altered to protect the innocentish): -

Code: Select all

# zmu -d /dev/video0 -q -v -Uuser -Ppass
Error, failed to get channel 0 attributes: Invalid argument

I was hoping that just by writing this post I'd spot something obvious, but my mind is so frazzled I can't think straight any more. Any help or advice would be much appreciated.

I guess the main questions are: -

1. What am I missing or doing wrong?
2. Will I have problems with multiple USB cameras or will Z "handle it"?

What kind of USB camera do you have? Is it a UVC camera (dmesg |grep uvc)?

If it is, you can use two different methods:
1. Use mjpeg-streamer (http://sourceforge.net/projects/mjpg-streamer/) which works similarly to the webcam-server software you are using, and configure ZoneMinder to use it as it would a network camera.
2. Configure Zoneminder 1.24.x to use the native V4L2 support and access the /dev/video0 device directly.

Can you screenshot or say what you have entered in your "Source" tab?

Multiple USB cameras should be no problem, I have several installations that are using 6+ USB cameras simultaneously

Thanks for your response Blazer! Although my dmesg doesn't mention UVC, as shown below, I can use v4l2 to access the camera: -

Code: Select all

% cvlc v4l2:///dev/video0 --no-video-title-show --no-audio

OK, so I uninstalled the ubuntu installed version and followed the instructions on this forum aticle: http://www.zoneminder.com/forums/viewto ... 73da1c885c and now I'm running ZoneMinder v1.24.2

I have 2 "Creative WebCam Vista" devices but only 1 plugged in currently.

The following is the result of me inserting it: -

Any ideas on my next move? I'm hoping it's something numpty at my end... It is worthy of note that I have no idea what values should be specified in the Source "Device Format" and "Capture Palette" and I've tried other settings with similar results.

Right, I'm at home with a broken arm so Amazon and eBay are not safe. I bought some additional WebCams (cheap as chips) and they came today!

I have them both working with ZM

I found a utility to look at the settings of devices supported by video4linux2. This has shown me that the driver being used for the new cameras is 'uvcvideo' and the older ones are being driven by 'ov519'.

These are the v4l2ucp stats for my devices: -

v4l2ucp - /dev/video0
driver: ov519
card: Creative WebCam Vista
bus_info: usb-0000:00:1a.0-2
version: 2.6.0
capabilities: 0x05000001
resolution: 640x480
fps: not yet working on ZM

v4l2ucp - /dev/video1
driver: uvcvideo
card: USB2.0 Camera (TeckNet C016) http://www.amazon.co.uk/TeckNet-Webcam- ... pd_cp_ce_1
bus_info: usb-0000:00:1a.1-1
version: 0.1.0
capabilities: 0x04000001
resolution: 320x240 (good picture but so very disappointed at the size...)
fps: 2.01
ZM Source Type: Local
ZM Device Format: PAL
ZM Capture Palette: YUYV

v4l2ucp - /dev/video2
driver: uvcvideo
card: USB2.0 PC Camera (Digiflex) http://www.amazon.co.uk/Webcam-Micropho ... p_ce_2_img
bus_info: usb-0000:00:1a.7-6
version: 0.1.0
capabilities: 0x04000001
resolution: 640x480
fps: 5.70
ZM Source Type: Local
ZM Device Format: PAL
ZM Capture Palette: YUYV

v4l2ucp - /dev/video3
driver: ov519
card: Creative WebCam Vista
bus_info: usb-0000:00:1a.0-1
version: 2.6.0
capabilities: 0x05000001
resolution: 640x480
fps: not yet working on ZM

The captured frame rate from the uvcvideo devices is very unimpressive! Something you've mentioned I note Blazer: http://www.zoneminder.com/forums/viewto ... 2b2781c071

I really would like the ov519 devices to work on ZM but I have no idea how or what to do next...

I was taking heed of your suggestions Blazer and trying to use mjpeg-streamer. The following is getting me an available image in Firefox http://127.0.0.1:8888/?action=stream: -

Code: Select all

chrisp:~/Downloads/mjpg-streamer-r63 % ./mjpg_streamer -o "output_http.so -p 8888" -i "input_uvc.so -d /dev/video0" 
MJPG Streamer Version.: 2.0
 i: Using V4L2 device.: /dev/video0
 i: Desired Resolution: 640 x 480
 i: Frames Per Second.: 5
 i: Format............: MJPEG
 o: www-folder-path...: disabled
 o: HTTP TCP port.....: 8888
 o: username:password.: disabled
 o: commands..........: enabled

I've configured ZM thusly: -

Source Type: Remote
Remote Protocol: HTTP
Remote Method: Simple
Remote Host Name: 127.0.0.1
Remote Host Port: 8888
Remote Host Path: ?action=stream
Remote Image Colours: 24 bit
Capture Width (pixels): 640
Capture Height (pixels): 480

I've also configured /dev/video3 similarly but I get this error when I try to run mjpeg-streamer on the 2nd device: -

Code: Select all

chrisp:~/Downloads/mjpg-streamer-r63 % ./mjpg_streamer -o "output_http.so -p 9999" -i "input_uvc.so -d /dev/video3"
MJPG Streamer Version.: 2.0
ERROR: could not find input plugin
       Perhaps you want to adjust the search path with:
       # export LD_LIBRARY_PATH=/path/to/plugin/folder
       dlopen: input_uvc.so: cannot open shared object file: No such file or directory

Is the other running instance locking the file?

Look, I'm almost there!

Uniquely unsuccessful camera purchase as indicated here http://ubuntuforums.org/showthread.php?p=8393899

No advance on the multi-mjpeg-streamer issue either...

Blazer · Post by **Blazer** » Sun Nov 29, 2009 9:26 pm

When using an mjpeg-streamer source, your "Remote Host Path" should be "/?action=snapshot", rather than the stream method you are using.

I also recommend using the "start.sh" that comes with mjpeg-streamer, and uncomment the line you want to use, as that script sets the LD_LIBRARY_PATH variable for you (which is what is keeping your input plugin from working).

You could also just do it on the command line like so:

# LD_LIBRARY_PATH=. ./mjpg_streamer -i "input_uvc.so -d /dev/video0 -f 15 -r 640x480 -o "output_http.so -w ./www -p 8080"

I have a script that I use to invoke multiple instances for multiple camera devices that I can post if you are interested.

Very interested. I've got both of my streamers going thanks!

I altered my start.sh to read like this: -

Code: Select all

#!/bin/sh
export LD_LIBRARY_PATH="/home/chrisp/Downloads/mjpg-streamer-r63"
/home/chrisp/Downloads/mjpg-streamer-r63/mjpg_streamer -i "input_uvc.so -d /dev/video0 -f 15 -r 640x480" -o "output_http.so -w ./www -p 8000" &
/home/chrisp/Downloads/mjpg-streamer-r63/mjpg_streamer -i "input_uvc.so -d /dev/video1 -f 15 -r 640x480" -o "output_http.so -w ./www -p 8001" &

I used '&' as I was getting no joy from '-b'...
