I've been baffling my brain with this some more.
I suspect the solution to the problem lies in this text.
/**
* Update the texture image to the most recent frame from the image
stream. This may only be
* called while the OpenGL ES context that owns the texture is current
on the calling thread.
* It will implicitly bind its texture to the GL_TEXTURE_EXTERNAL_OES
texture target.
*/
public void updateTexImage() {
nativeUpdateTexImage();
}
I suspect the key is figuring out what "while the OpenGL ES context that
owns the texture is current on the calling thread" means.
Anyone have some Advil and a Babel fish?
