Great work! Thank you!

I would like to modify the libraries because I am having this excepition:

I/AbsUVCCameraHandler: supportedSize:{"formats":[{"index":1,"type":4,"default":1,"size":["160x120"]},{"index":2,"type":4,"default":1,"size":["160x120","160x122"]},{"index":3,"type":4,"default":1,"size":["160x120"]},{"index":4,"type":4,"default":1,"size":["160x120"]},{"index":5,"type":4,"default":1,"size":["160x120"]}]} V/zhf_debug: handleSetPreviewCallback: frameCallback=com.example.o0orick.camera.MainActivity$5@d9370d9 I/libUVCCamera: [14743*UVCPreview.cpp:266:callbackPixelFormatChanged]:PIXEL_FORMAT_RGB565: V/CameraThread: handleStartPreview: W/System.err: java.lang.IllegalArgumentException: Failed to set preview size W/System.err: at com.serenegiant.usb.UVCCamera.setPreviewSize(UVCCamera.java:328)

With these values:

private static final int PREVIEW_WIDTH = 160; private static final int PREVIEW_HEIGHT = 120; private static final int PREVIEW_MODE = 0; // YUV

Any suggestion to solve it?

Thank you very much in advance

Hi @feng612266,

What camera (specs) are you using?

It depends on your resolution and your video format.
