So far every platform supported EGLImage extension by using EGL_NATIVE_PIXMAP_KHR. I found some examples for the iMX53 to get it running with EGL_NEW_IMAGE_FSL but this seems to be not supported by the iMX6, is it? Also I would prefer to have the official khronos extension EGL_NATIVE_PIXMAP_KHR instead of a proprietary FSL one. </P><P></P><P>The things that bugs me most is the lack of official documentation. Are there also some hints what's the best practice regarding streaming texture uploads? I know there are glTexDirectVIV methods available (although there is also a lack of documentation especially regarding thread safeness) but since this is again a proprietary extension, I wonder if it isn't possible to use an EGLImage with the same performance.&nbsp; But I couldn't even found some information about possible image formats for an EGLImage, in case the iMX6 supports this extension at all. </P></BODY></HTML> Tue, 11 Feb 2014 11:02:18 GMT volki 2014-02-11T11:02:18Z eglImage vs glTexDirectVIV https://community.nxp.com/t5/i-MX-Processors/eglImage-vs-glTexDirectVIV/m-p/223195#M15269 <HTML><HEAD></HEAD><BODY><P>I'm currently try to port our cross platform framework to different architectures.
