Mali400MP2 and 4K video

8 5476
I was just wondering if the GPU was capable of decompressing 4K video.

Maybe its ability is not enough to do this.

is there a repository or a howto  to get the most out of this GPU

opengl etc. ?

i want to use this with opencpn to plot the chart faster

4k? I can't even play HTML5 video's (youtube and other HTML5 videos) @ 360p in Lubuntu v2 or v3 with a decent framerate So I'm not going to try 720p or 1080p until I got that working
Am I missing something?

I will record your question to ask allwinner for help

As far as I know there is a first buggy try to port libvdpau (VPU - video processing unit) to Allwinner A10, A20 and A31?! But better support from Allwinner would be essential.
GPU-drivers vor 2D/3D acceleration should work but there is need for special xorg-drivers as far as I know.

How much information and support can we expect from Allwinner? There are many developer boards out there using Allwinner SoCs but there needs to be much more development for the opensource-drivers.

As I know, sunxi and allwinner are two different organization. We will try.

I hope so!!! The SoCs have enough potential for most of the common tasks computers are used for. One big thing would be better video/audio decoding t!!! As the community gets bigger the interest for better opensource driver-support will get bigger, too ...

Ps. in germany the Banana Pi is sold by Allnet and they are for sure interessted in selling more units! Maybe they can apply some presure to allwinner ;)
