cheese doesnt work in beagleboneblack installed with angstrom, used along with chipsee LCD

Ankur Tank

I am using chipsee LCD + beaglebone black and Logitech Webcam C270. I am using angstrome OS distribution provided by Chipsee.
I wanted to use Cheese and see if webcam works fine or not.
When i open cheese it opens and shows waiting animation and then closes without any error messages or something.

Any suggestions/pointers for debugging this issue?

output of journalctl -a -f when i run cheese

Hi Ankur,

If you want to test the webcam, you can use "mplayer"

Try "dmesg" command to display error messages,

Try "strace" command while you running the command (cheese).

Hi Titus,

Thank you for reply,
Just to add i tried steps in following link to capture video,

http://derekmolloy.ie/beaglebone/beaglebone-video-capture-and-image-processing-on-embedded-linux-using-opencv/
But every time i run "./capture" i get "/dev/video0" device is busy.

The busybox version of angstrom distribution provided by Chipsee doesnt have "lsof", it has "fuser", i tried "fuser" but couldnt find who is using /dev/video0 device.

I had tried mplayer also but the same problem, dmesg didnt help me(or i coudln't figure out what is happening there), i will try strace with cheese.

Thank you,

Regards,
Ankur

Hi Ankur,

Have you ever tried "uvccapture" ?

Hi Titus,

I think i had tried to install it but i didn't find that in Angstrom packages.

I will recheck and update.

Ankur

Hi Ankur,

You can cross compile the "uvccapture" and it requires libjpeg to successful build.

Hi Ankur,

I'm not sure that the below changes give solution.

Try to disable the "USB suspend/resume" configurations in kernel through menuconfig.

Hi Titus,

Thank you for reply,
In my opinion this issue has something to do with driver or kernel configurations, so solution you provided might actually work,
I will try that and let you know.
