Android r10.2 UVC Camera problem

[ToxicAvenger]

Hello,

I'm using custom board based on i.MX53 QSB, and Android r10.2. I'm trying to get UVC camera to work.

My camera is recognised as WebCam-HM2055

Camera is visible, when it is connected:

uvcvideo: Found UVC 1.00 device WebCam-HM2055 (058f:5608)

input: WebCam-HM2055 as /devices/platform/fsl-ehci.0/usb1/1-1/1-1:1.0/input/input3

Also /dev/video0 is created.

Also Android application: openxc/android-webcam · GitHub

gets preview from camera, but when I try to open system application "Camera", i have exception:

I/ActivityManager( 2367): Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10200000 cmp=com.android.camera/.Camera } from pid 2422

I would like to get this camera working in Android system, not only in openxc android webcam application

The R10.2 BSP is too older, you'd better update to R10.4. UVC camera had been verified on that release.

Hello,

How to get 10.4? Adeneo have only 10.3.

Is there any option to apply camera patches from 10.4 to 10.2? I have many modification in 10.2 to work with custom board.

Regards,

Toxic

The freescale R10.4 BSP can be downloaded from http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX535&nodeId=018rH3ZrDR988D&fpsp=1&...

Run-time software -> Operating System Software-Board Support Packages -> IMX5X_R10_4_ANDROID_SOURCECODE

I searched the R10.4 release, and attached all "UVC" named patches here. You can check if they had been applied in your BSP.
