问题
I'm writing a simple android app for taking a photo from the camera. I'm following this tutorial photobasic. The program compile and run fine if i use the emulated camera on the android emulator. If i use the webcam0 device, my laptop webcam, i get this error:
ERROR: _camera_client_query_start: Cannot start camera 'AndroidEmulatorVC0' for NV21[640x480]: Result too large
I followed the solutions to this question webcam-in-android-emulator-cannot-start-camera-and-result-too-large without any luck.
Here is my emulator config.ini:
