Hello All

Please help. I want to play video in OpenGL.

I create SurfaceView, MediaPlayer. In MediaPlayer i call method
setSurface which give created by me in the thread of GL surface.

int[] textures = new int[1];
// generate one texture pointer and bind it as an
external texture.
GLES20.glGenTextures(1, textures, 0);

GLES20.glBindTexture(GLES11Ext.GL_TEXTURE_EXTERNAL_OES, textures[0]);

GLES20.glTexParameterf(GLES11Ext.GL_TEXTURE_EXTERNAL_OES,
GL10.GL_TEXTURE_MIN_FILTER,
GL10.GL_LINEAR);

GLES20.glTexParameterf(GLES11Ext.GL_TEXTURE_EXTERNAL_OES,
GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR);
// Clamp to edge is only option.

GLES20.glTexParameteri(GLES11Ext.GL_TEXTURE_EXTERNAL_OES,
GL10.GL_TEXTURE_WRAP_S,
GL10.GL_CLAMP_TO_EDGE);

GLES20.glTexParameteri(GLES11Ext.GL_TEXTURE_EXTERNAL_OES,
GL10.GL_TEXTURE_WRAP_T,
GL10.GL_CLAMP_TO_EDGE);
texture_id = textures[0];
SurfaceTexture mTexture = new SurfaceTexture(texture_id);
Surface mSurface = new Surface(mTexture);
MediaPlayer mp = new MediaPlayer();
mp.setSurface(mSurface); **Is it correct?**

SurfaceTexture has method updateTexImage()? How correct use this
method?

I have no experience in SurfaceTexture but I would expect workflow goes roughly as;

1. Implement SurfaceTexture.onFrameAvailable(..).
2. Once new frame is available trigger a runnable to be ran on render thread (GLSurfaceView.queueEvent(..)).
3. On render thread runnable call SurfaceTexture.updateTexImage().

This way you should be able to update texture in a way it shouldn't harm rendering - meaning texture is not altered during rendering. But as said, I haven't tried this myself yet, will try something like this as soon as I get my hands on a device running on API 14+ though.

Actually, after thinking about this for awhile, it may be best to call
updateTexImage in rendering method instead (Renderer.onDrawFrame). There
you know for sure underlying texture is created etc.
