How to make the default camera android app work on QSB

PSC1z — Sun, 02 Oct 2011 15:31:58 GMT

Hi all,

If I plug-in a USB UVC camera, the kernel can recognize the camera but the

default camera android app crash while opening the app on Adeneo Embedded

Gingerbread Release 4.0. Do any one know how to make the default app works with

uvc compatible camera?

Make sure your kernel can handle UVC cameras:

Enable the UVC camera
Device Drivers --->
               <*> Multimedia support --->
         [*]   Video capture adapters --->
       [*]   V4L USB devices --->
         <*>   USB Video Class (UVC)

And try to include this prop

setprop front_camera_name uvc
setprop front_camera_orient 180

I'm not sure this will work for QSB, since I'm not sure what is supported on this release. Please, try it and let me know your logcat result

Hi Daiane,

Thanks for your help. I've sure that I've enabled UVC support in kernel.

Below is the console message and logcat when the camera is plugin and start the camera app.

Console:
