I think there is an extensions to check if you can also use mipmapping and different wrapping modes. They term is limited NPOT for setting the glTexParameteri below. You can also use non-limited NPOT, with extensions. See: <a class="moz-txt-link-freetext" href="http://www.khronos.org/registry/gles/extensions/APPLE/APPLE_texture_2D_limited_npot.txt">http://www.khronos.org/registry/gles/extensions/APPLE/APPLE_texture_2D_limited_npot.txt</a> <a class="moz-txt-link-freetext" href="http://www.opengl.org/registry/specs/ARB/texture_non_power_of_two.txt">http://www.opengl.org/registry/specs/ARB/texture_non_power_of_two.txt</a> There are also some arbitrary restrictions on Android for different hardware, but in general we haven't run into any problems as the screen resolutions usually fit into these restrictions. For instance: <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> PowerVR SGX requires the width & height to be multiples of 2 and I've heard that some hardware requires multiples of 8. But if it's only uses for screen capture then you shouldn't run into any problems.

They just need the following set to have NPOT (Non-Power of Two) settings, glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); And mipmaps should be turned off as they make no sense. We use NPOT all over the place for video textures. </pre> </blockquote> <pre wrap=""> hmm.. So, essentially, we should also emit the above glTexParameteri calls when replacing the glEGLImageTargetTexture2DOE with glTexImage to ensure the NPOT get accepted...
