Hi,

I have android running on beagle (2.6.27) took from git tree from android porting to beagle wikipage.

Now, i have usb camera connected to beagle board. its been detected by driver.

v4l-info confirms the lower interface.

i want to use webcam with android.

So, i went android-src/frameworks/base/camera/libcameraservice,

Here, we can replace normal check pattern by camera hal driver (libcamera.so).

Where to get this camera hal for omap.

so that libcamera service uses this camera library instead of fake camera.

Is it available. is android supports webcam and v4l2 driver interface.

Any links regarding this.

Regards,

This is quiet an old wiki page
http://processors.wiki.ti.com/index.php/TI-Android-DevKit-Camera_Porting_Guide
but it should be able to get you started.

If you are well aware with v4l api you can make an application of your own usind ndj.we did the similar task of interfacing uvc camera to camera less tablet and then with acer tablet.you need to first create a v4l based command line app to capture snapshot or streamed data which you can transfer to canvas api of android via jni interface.you don’t need to go through usual camera path to transfer your data from hardware to Android gui.
