Not directly answering your question Jeff, but anyway, I recommend looking into using bc-cat on the SGX if possible.
http://processors.wiki.ti.com/index.php/OpenGLES_Texture_Streaming_-_bc-cat_User_Guide You will have to write your own video render item for Qt Quick, because you need a special texture lookup in the fragment shader (it's not a regular texture). Also you need a custom video surface class (inheriting QAbstractVideoSurface), that will upload the texture for you using bc-cat. Apart from the faster texture uploads, bc-cat also automatically converts YUV to RGB for you so there is no need for YUV-RGB conversions in the shader (also faster).
