Why OpenGL ES texture mapping is very slow?

opengl-es

I have an Android application that displays VGA (640x480) frames using OpenGL ES. The application reads each frame from a movie file and updates the texture accordingly.

My problem is that, it is taking almost 30 ms. to draw each frame using OpenGL. Similar test using the Canvas/drawBitmap was around 6 ms on the same device.

I'm following the same OpenGL calls that VLC Media Player is using, so I'm assuming that those are optimized for this purpose.

I just wanted to hear your thoughts and ideas about it?
