Hello,

I'm using i.MX53 SMD, and Android r10.4. I'm trying to get UVC camera to work.

I refer ro user guide to enable uvc funcion

First,I enable the uvc driver.

*   Enable the UVC camera

 

Device Drivers  --->

              <*> Multimedia support  --->
                      [*]   Video capture adapters  --->
                              [*]   V4L USB devices  --->
                                      <*>   USB Video Class (UVC)

 

Second, I add the following prop. to ini.fresscale.rc

#Define the config for dual camera

    setprop back_camera_name ov

    setprop back_camera_orient 0

    setprop front_camera_name uvc

    setprop front_camera_orient 180

.

But UVC camera is not working fine.

After opening the camera app,I got the following error message.

 

I/FslCameraHAL( 2185): The capture device already open

E/FslCameraHAL( 2185): Info!get pmem total size 67108864

E/FslCameraHAL( 2185): PrepareCaptureDevices error

E/MemoryHeapBase( 2185): mmap(fd=32, size=0) failed (Invalid argument)

 

Does anyone help me to solve this problem?

 

Best regrads,
