Matrix34F projMatrix = mRenderingPrimitives.getProjectionMatrix()

Hello guys,

I am using the Vuforia sample for play video. But I take  "Unable to update video background texture" error because of;

[quote]Matrix34F projMatrix = mRenderingPrimitives.getProjectionMatrix(viewID, state.getCameraCalibration());[/quote] method needs 3 parameters but sample use 2 parameters. I added a random int value but it does not work. I am newbiee on Vuforia for Android Studio there for could you guys help me to solve this problem?

Thank you
