OES_EGL_image_external Render Texture without glTexture2D

Hello,

Is there any possibility to use OES_EGL_image_external with Mali 400 on Linux.

I know this feature is used in Android ICS. But I can't find any example, reference code or document of that.

Thanks & Regards

Hi Piyush,

Thanks for the question, yes this extension is available for Linux as well as Android. The mechanism of getting data into an EGLImage will differ on Linux, but on the GLES side it's exactly the same for sampling etc. I'm afraid I don't think we currently have any sample code for this, but the extension documentation should be all you need:

Hope this helps,
Chris
