This means that there were some parameter invalid or not supported.

From log, the paramaters were set up as:

parameters.setPreviewFpsRange(25000, 30000)

parameters.setPreviewSize(320, 240)

parameters.setPreviewFormat(ImageFormat.YV12)

parameters.setPictureSize(/*closest to 320*240*/)

Please try this snippet on your usb camera to see if the parameters are not supported.

LocalCameraStreamParameters can't set setPreviewFormat。

How to use this?

SDK3.0
VideoCaptureAndroid.class:
PreviewFormat change from 842094169  to 17
parameters.setPreviewFormat(17);

This error was solved，but video's color is black ，how to deal this color question?

Is the local video black? or remote one?
