camera on, but it doesn't show anything

[dtorologic]

Hello, I have two web cams, one of them works fine, and the other tells me that it is open, but it doesn't show anything.

I leave you the debug, in case it helps:

I/UVCCamera( 6796): open camera status: -5476376628106891136, size: {"formats":[{"index":1,"type":6,"default":1,"size":["1280x720"]}]} I/CameraUVC( 6796): aspect ratio = null, getAllPreviewSizes = [PreviewSize(width=1280, height=720)], I/CameraUVC( 6796): getSuitableSize: PreviewSize(width=1280, height=720) I/CameraUVC( 6796): aspect ratio = null, getAllPreviewSizes = [PreviewSize(width=1280, height=720)], I/MultiCameraClient( 6796): Audio record by using system mic 2 I/CameraUVC( 6796): aspect ratio = null, getAllPreviewSizes = [PreviewSize(width=1280, height=720)], E/CameraUVC( 6796): setPreviewSize failed, try to use yuv format...
