[chenguoyin]

You may counter issues when enable the uvc camera in Android R10.3.2 release package.

If so, you can apply the attach patch into myandroid/hardware/mx5x

Dear Chen,

Now I am able to connect and work one of my logitech quick cam in USB port and via android camera apk.

What did is

1. Applied the patches as you specified .

2. changed setprop backcamera as UVC and orientation to 0

Now what happening is when changing to video the apk gets force close. What should be the next step to solve this issue. Reply immediate.

01-02 00:02:29.040 I/FslCameraHAL( 2074): Face Front Camera is #, orient is 0

from the log, you still not set the backcamera to be UVC.

Be sure you set the property in init.freescale.rc

Hi Chen,

With the application of your patches and setting back-camera as UVC with 0 orientation things worked well. I found an interesting behavior when went through the testing.. They are,

1. camera app outputs "cannot connect to camera" when the output display is HDMI and has no problem when the display is VGA

2. Camera app force closes when going to video mode(When display is VGA also).

Hi Chen,

Now when I connect an usb webcam and try to open the default camera app it says "Camera error. Cannot connect to camera " .

The logcat -v time of those events are as follows

Hello Guoyin Chen,

Does 10.4 need to apply this patch, or this things are applied by default in this build?. 

I Have connected a web cam to our hardware( imx535,ref. ARD) and tried to open the camera app. which ends in a force close.

here is the Log,

usb 2-1.4: new high speed USB device using fsl-ehci and address 5 
uvcvideo: Found UVC 1.00 device USB2.0 Camera (1e4e:0100) 
uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported. Enabling workaround. 
input: USB2.0 Camera as /devices/platform/fsl-ehci.1/usb2/2-1/2-1.4/2-1.4:1.0/input/input2

Any clue, i am also working around the same now
