UVC camera enabling on DM814x Android ICS

Naveen Yanamaddi

Hi,

I am working on DM814x evm, In that I have ported Android ICS 4.0.3. I am trying to capture Image using USB camera but I couldn't able through. When I connected USB camera device nodes getting created like video0, video1, video2, video3. But When I click on Camera Application in Application launcher it is saying that "Unfortunately, Camera has stopped". Please suggest some ways to solve this problem so that I am able to see camera preview on my board DM814x Android ICS

Here I am giving logcat messages

Hi Naveen,

Some tips:

Check in kernel that you have selected the UVC driver in multimedia devices.

Check /dev/videoX permission.

Maybe, these links can help you to solve this problem:

Hi Naveen,

Yes, I solved the problem. In my case, my system (BeagleBone with ICS) doesn't support a large size as VGA, and it works fine with QVGA resolution (320x240), but I don't know the reason. I wrote about it this post:

http://e2e.ti.com/support/embedded/android/f/509/p/212484/770619.aspx#770619

You can check it changing the resolution (if you can) in the app camera parameters (resolution). Also, you can modify the resolutions in CameraHardware.cpp file and compile, again, the camera.omap3.so library.

At the moment, I can't use my system with a better resolution and I can't take pictures with a major resolution than QVGA. On the other hand, I can't use OpenCV because the example applications don't launch in my system. I wrote about it in this post (without reply):

http://e2e.ti.com/support/embedded/android/f/509/t/218930.aspx

I hope this post will be helpful to you.

Thanks marc. Now everything is working fine. I am able to see preview of the camera and I am able to capture Images. But When I tried to capture video it saying that "Unfortunately Camera has stopped working". Can you suggest for capturing video on my board.

Hi Naveen,

Neither can I capture the video. I have not tried to solve this problem so I don't know the reason.

I remember that I read, I don't know where, that the video capturing is not support at the moment.... but I'm not sure about it.

yeah marc.

I have also heard that video capturing is not support at present. I will start work on this video capturing, meanwhile if you find any info please let me know.
