GL_INVALID_ENUM and GL_INVALID_OPERATION

Hi every body,

I'm newer in Vuforia. I'm trying to develop a demo that is integrate between Cloud Regconize and Video Playback. I use the sample of Vuforia for this demo. 

The demo's procedure is: when the app detected the image target by using the Cloud Regconize, it will render the splash image of video with the icon, and then when I click on the play button, it will play the video.

But when I render the splash image of video I receive the error GL_INVALID_ENUM althought the splash image render to the screen normally. When I click on the play button, the video cannot play and crash, I receive the error GL_INVALID_OPERATION.

This is the error message that I received in the Log:

- This is the error I received when I render the splash image

 

E/Adreno200-ES20(17551): <process_gl_state_enables:456>: GL_INVALID_ENUM

 - This is the error I received when  I click on the play button

 E/Adreno200-ES20(17551): <qgl2DrvAPI_glBindTexture:656>: GL_INVALID_OPERATION
 E/SurfaceTexture(17551): [unnamed-17551-2] error binding external texture image 0x19d79a8 (slot 0): 0x502

 - And this is the crash message

E/AndroidRuntime(17551): FATAL EXCEPTION: GLThread 2159
E/AndroidRuntime(17551): java.lang.RuntimeException: Error during updateTexImage (see logs)

E/AndroidRuntime(17551):  at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1218)

I tried to research on Google and try some solution that involve to this error, but it not work! I tried below solutions: - GL_INVALID_ENUM is generated if target is not one of the allowable val-ues.- GL_INVALID_OPERATION is generated if texture has a dimensionality thatdoesn't match that of target.- GL_INVALID_OPERATION is generated if glBindTexture is executed betweenthe execution of glBegin and the corresponding execution of glEnd.  Any one can help me! Thank you so much!
