Samsung Galaxy Tab 4 green screen

July 18, 2014 - 12:05am #1

Vuforia SDK Version: 3.0 -

Description with steps to reproduce:

I have Samsung Galaxy Tab 4 10''(SM-T530) Android 4.4.2.
 

Step to reploduce:

  • check if the device support npotexture (no power of 2 texture)
  • create frame buffer with this size (width=1066 and height=800) [note: I try with powe of 2 or quad texture but is the same]
  • bind frame buffer
  • call cpp method to render frame
	glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

	// Get the state from QCAR and mark the beginning of a rendering section
	QCAR::State state = QCAR::Renderer::getInstance().begin();

	// Explicitly render the Video Background
	QCAR::Renderer::getInstance().drawVideoBackground();

 

 

drawVideoBackGround generare the follow error and the output is a texture with only green component. 

LogCat:

W/Adreno-ES20(2471): <core_glTexSubImage2D:575>: GL_INVALID_VALUE

glError: 1281

Can you help me?

Note: the software work fine in Samsung Galaxy S, Samsung Galaxy S3, Nexus 5, Kindle Fire 7HDX, LG G2

This is a known issue we have seen on a few devices with SDK 3.0.5 (or 3.0.6 if using Unity) and there is a fix expected with the next upcoming release of Vuforia, which should be made public soon.
