logitech quickcam pro 4000

[wpte]

hello guys,

after a long time searching and bidding on ebay i finally found one of these working webcams.
basicly it works fine with oleg firmare, but it does take nearly 100% of the cpu even when you're not watching or setting it to a lower resolution
now i had this idea to disable to cam and hope the drivers would load up, but the heavy proces would stay away so "motion" could do the job.
unfortunately, the cam didnt appeared on /dev/video0 anymore.
i couldnt find any working drivers on ipkgfind, so is there an insimod for this or something?
it is the pwc driver
at least... that is what the router said.
thanks

[dyonisos]

how about
insmod videodev
insmod pwc
insmod pwcx

[wpte]

ah thanks
how do you know these insmods anyway?
or do you just guess

I still have problems loading the webcam tough...
I get a response on /dev/video0
while it's really in /dev/v41/video0
but then it says it doesnt exist
but on the /dev/video0 I can't view any video while it's properly loaded up in the log
any idea?

[wpte]

Oh, I have the right video device now...
but, next problem:

so, I've tried out some palletes... didn't quite work
anyone?

[dyonisos]

I have never used motion -maybe parameter issue in motion.conf file?- have you tried mvc application alternatively? Cheers

I know, I've been trough the whole config file, there is an option how to set the pallete... it's just on default now.

where can I get this mvc application?
google says nothing and ipkgfind doesnt know

[wpte]

motion seems to have problems with logitech drivers after some searching

this is the output when I try to do your thing:

I don't think this is right

[dyonisos]

it says successfully terminated... try /bin/mvc or wherever mvc has been loaded

mvc -h gives the command options

mvc version 0.8.9 - motion detection video capture program

Usage: mvc <options>

-B picture brightness value.
-C picture contrast value.
-D run in daemon mode.
-O Base directory for output images. default is current dir.
-o Don't create sub-directories for output.
-t Print timestamp on image.
-d <device> video device (default:/dev/video0).
-e <program> excute a external program while motion detected.
-f {jpeg|png} set output file format. default is jpeg.
-q <quality> jpeg quality setting.
-h print this help.
-i <channel> which input channel to use, default is 1, or 0 if only 1 input.
-m use mono color (grayscale) for capture.
-n {pal|ntsc|secam|auto} video norm to use, default: PAL
-s XxY size of the output image, example: -s 640x480
-a HxV block division number in Horizantal and Vertical. Ex: -a 16x8
-b <diff_block_limit> threshold of hot block number.
-c <diff_color_limit> threshold of block color difference.
-w delay time for each capture(seconds), example: -w 0.5
-l logfile used in daemon mode. default is null.
-v increase verbose level for more details, can multiple applied.

it works for both Logitech and Philips webcams

it says "Read-only file system" in the installation, so it can't write.

I can't find the program as it isn't installing to /opt
I tried:

/sbin/mvc
/bin/mvc
mvc

nothing

[dyonisos]

I have mvc installed on /tmp/harddisk/mvc with 2 subdirectories bin and lib.
bin consists of setpwc, mvc and camsrv. lib holds under ./modules/2.4.20 pwc.o and pwcx.o object driver files. That's it.
There is something wrong with your installation.

maybe you try to re-install.... and prior to that do a find / -name mvc as it was loaded somewhere.

[wpte]

I think this is not an optware package
what kinda parameters does ipkg need to install it to a specific directory?
as far as the ipkg parameter list on my router goes, it doesn't know any.

it's trying to install to root, not to opt
as long as it can't write, I can't load the program

[wpte]

I have still no good working program for my webcam...
I would like to view it life, and maybe some motion detection that writes to disk

anyone have a good program in mind?
I've searched already and try to compile some stuff... no good luck

For live viewing have you tried palantir? It supports also audio and much more.

Cheers dyonisos

[wpte]

that worked better

/opt/mvc/bin/camsrv -r QSIF -d 1 -v --device /dev/v4l/video0 -q 100
Video device: /dev/v4l/video0
Streaming capture delay: 1s
No Philips webcam detected.
Requested dimensions: 160 120
Actual dimensions: 160 120
Initialising server

Got connection from 192.168.2.100

the only problem is, small image output (can't get it higher than 160x120, just doesnt allow me) and 60% cpu even when I choose for a lower framerate


the palantir also works a bit, I got it compiled...
but it kinda fails at starting:

can't get it started so far, it looks more promising to me tough


edit:
the log replied with this:

Jun 30 13:01:48 kernel: pwc Video mode SIF@15 fps is only supported with the decompressor module (pwcx).
Jun 30 13:02:36 kernel: pwc Video mode SIF@10 fps is only supported with the decompressor module (pwcx).
Jun 30 13:02:42 kernel: pwc Closing video device: 48 frames received, dumped 0 frames, 0 frames with errors.

that means the mvc uses a decompressor module?
