Did you get any good result?
Could you share your code? Thanks in advance.
I am looking at it too. It seems there are a bunch of spaces to modify in
order to let video output to an OpenGL texture.
Just a little wondering why Google doesn't publish an example, since it
seems many people ask
Yes, you're right.
I had to change the bind calls to this:
GLES20.glBindTexture(GL_TEXTURE_EXTERNAL_OES, mTextureID);
Thanks.

How did you bind
I fiddled with a bunch of approaches for binding. The current code looks
like this:
int[] textures = new int[1];
GLES20.glGenTextures(1, textures, 0);
mTextureID = textures[0];
GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, mTextureID);
GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D,
I don't think your bind texture call is correct see *bold* below:
*The texture object uses the GL_TEXTURE_EXTERNAL_OES texture target, which
is defined by the
GL_OES_EGL_image_externalhttp://www.khronos.org/registry/gles/extensions/OES/OES_EGL_image_external.txtOpenGL

Does anyone know how to play a video on an OpenGL texture?
I tried something like this, but no dice:
int[] textures = new int[1];
GLES20.glGenTextures(1, textures, 0);
SurfaceTexture st = new SurfaceTexture(textures[0]);
Statics.mp.setSurface(new Surface(st));
You must call updateTexImage() on SurfaceTexture when a new frame is
available (use an OnFrameAvailableListener to be notified.)

I'm calling updateTexImage now, and I'm getting some weird error:
