iMX6 hardware decode issue on Android

[Carlos Rafael Giani]

You are referring to the Vivante video texture extension. While it does 
allow for zerocopy by using DMA to the video framebuffer, it also 
requires custom, Vivante-specific code, which glimagesink doesn't have. 
This is why I wrote eglvivsink in gstreamer-imx. Ideally, it would be 
possible to hook up the Vivante stuff through GLUploadMeta, but the 
discussion about this has been going on for a while:
