eglImage vs glTexDirectVIV

Question asked by volki on Feb 11, 2014

I'm currently try to port our cross platform framework to different architectures. 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.


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.  But I couldn't even found some information about possible image formats for an EGLImage, in case the iMX6 supports this extension at all.
