I read it should be possible to transfer pixel data directly inside the GPU memory using pixel buffer objects. What I’m not understanding is if PBO is supported in OpenGL ES 2.0. I found incoherent information. Is PBO supported under OpenGL ES 2.0?
If not, is there any other way with OpenGL ES 2.0 to place data (RGBA32) directly into a texture?
Possibly not, it depends on the video graphics hardware driver you are using. Texas Instruments has provide a bc-cat driver to do the job on OMAP35x and AM35x platforms. Other company like Freescale , do not provide the same function. For opengl es standard, this function is not defined.
