Anyone tried to use uvccapture on embedded???

I've port uvccapture on ARM arch, it can capture jpg where the jpg can not be read, so what is yours camera model??

I saw your earlier post and noticed you were also interested in video capture. In short, no I have not used uvccapture on ARM. I have, however, captured video from a Logitech webcam with an ARM board.

I'm not sure if this will be helpful to you, but if you're interested, I can through the details.

Did you build the drivers for your webcam separately or were they included in the kernel?

Thank you for answering my post.
There are 3 webcams on my hand: ZC0305 webcam, SN9C120 and a logitech quick cam messenger. I'm interested in video capture very much, however i couldn't find any software or utilities, tried "servfox or the webcam_sever" but not work at all... I've compiled linux kernel 2.6.28.2 and 2.6.29.1, webcam drivers are included in the kernel.

I'm very interested in your way of video capture, and the model of your logitech webcam.

I used a Logitech QuickCam Communicate MP, found here:

http://www.logitech.com/index.cfm/38/4224&cl=us,en

The webcam I used didn't have support in the kernel so I build the "uvcvideo" drivers separately from source:

http://linux-uvc.berlios.de/

Once the drivers for the webcam were installed, it was listed as "/dev/video0" in my filesystem. Then I was able to use gstreamer to capture video input from the webcam and output it to a file. You can also stream it over a network or to an output screen.

Are you familiar with gstreamer at all? You would have to cross-compile the gstreamer-core, gst-plugins-base, gst-plugins-good packages for your system.

I think the Logitech QuickCam Messenger that you have should work as a "video4linux" source for gstreamer. An extremely simple gstreamer command to write capture to a file would be:

gst-launch -v v4lsrc ! filesink location=/video.out

I think that should get you going in the right direction. Let me know if you have any questions.

BTW, I was using the 2.6.24 kernel so they may have added support for that webcam in the kernel versions that you are using.

Thanks, it seems gstreamer is quite complicated, and i found this site http://f170.blogspot.com/2008/12/gstreamer_20.html a chinese website of compiling gstreamer on ARM, i try to follow his steps and everytime i configuring involves more than one path in CFLAGS or LDFLAGS, it always reported an error of unrecognized option of the second path???

On the other hand, i've fixed the uvccapture by using a UVC camera "logitech camera e3500", which is on the list http://www.quickcamteam.net/devices

If you copy-paste your configure command, I can try to help you out. If you want to pass multiple paths to CFLAGS and LDFLAGS, use quotes. For example:

CFLAGS="-I/usr/include -I/usr/local/include"
LDFLAGS="-L/usr/lib -L/usr/local/lib"

It's not so bad to build but you have to first have the necessary dependencies. Gstreamer requires glib2, libxml2 and libz so you have also have to cross-compile and install those.

I haven't used any other program to capture video so I can't give any other suggestions but Gstreamer worked great for me.

Thanks, I've tried "uvc streamer" today, and it works fine and simple, quite small in size, what is the size of gstreamer after complied?

hi i am working in OMAP ARM9 board,trying to port the USB webcam(logitech quickcam Messenger) in the board. plz do say me procedure to port in the board.so that i can capture the picture.

Actually, i haven't work in porting for months and finally as you read my post in this thread before, i have abandon to use the logitech quickcam messenger, instand i bought another UVC camera which work fines in kernel 2.6.29.1 with UVC camera drivers inside.

I don't know if the latest kernels are well support with the quickcam messenger, or somebody wrote a driver for it because it seems not working when i'm using 2.6.29.1 at that time...maybe my own problm only

I am using cm -t3530 (compulab) omap3530 based arm kit. it works on kernel 2.6.32.

I want to capture video from my logitech quickcam messenger webcamera. my camera is detected by my board when I type lsusb.

mplayer only plays audio on my board.

warm regards.
