Question

I'm working with Vuforia SDK (Android), with Videoplayback sample, and I sometimes get a bug: inverted, mirrored video on the target. Here's screen (number 2):

Answer 1

I have solved the problem by changing the

float videoQuadTextureCoordsTransformed[] = { 0.0f, 1.0f, 1.0f, 1.0f, 1.0f, 0.0f, 0.0f, 0.0f, };

to

float videoQuadTextureCoords[] = { 0.0f, 1.0f, 1.0f, 1.0f, 1.0f, 0.0f, 0.0f, 0.0f, };
