i.MX6SL Android 4.4.2 EVK USB Camera preview callback not enabled issue

[malleswari]

Hi,

Our requirement is to read different barcodes (1D, 2D like QRcode, PDF417 ...etc) using 5mp USB camera.

Processor : 1.MX6SL

Target Board : EVK

OS : Android 4.4.2 BSP

Camera: USB 5mp truly make

Connected : USB OTG port of EVK board

Camera config:

     setprop back_camera_name uvc

     setprop back_camera_orient 0

We tested with ZBarScanner-master application and zxing-android-embedded-master applications.

Both are failing in Camera HAL layer (disableMsgType 0x10, Preview callback not enabled 10, enableMsgType 0x10, Disabling Preview Callback).

Please find attached log with zbar cam for your reference.

Kindly suggest us to resolve the issue.

Regards,

Malleswari

Hello Suguna,

Do you check what kind of Camera it is using the ZBarScanner-master application and zxing-android-embedded-master applications,  I think if you are getting the error in the Camera HAL it is because the CAMERA need to be configure in a way to get the application the info,  is the camera crashing also with the photo android based application?  Did you register the USB Camera in the configuration file? what was the process you follow to add the camera can you share?
