ubuntu-14.04-core with gpu-accelerated VLC (sdcard/nand) ?
« on: April 25, 2014, 05:15:25 pm »
Hey!

I'm looking to build a working 14.04-ubuntu server starting from a core install, then adding VLC (gpu-accelerated via cedar or vdpau) and MALI drivers (for chromium gpu-accelerated).

So far, I've successfully built and booted on a 14.04 Ubuntu Core image using:

- u-boot-sunxi-with-spl-cb2-20130111.bin

and

- ubuntu-core-14.04-core-armhf.tar.gz

It worked out of the box thanks to this tutorial :


The OS looks stable and quite fast, should I worry about specific things with this setup ?

For now, I'm looking for help to correctly setup the cedar_dev module/device to make the board play HD videos with GPU acceleration with the smallest payload. I've already built VLC with cedarX support successfully in the past, would like to try the open-source version that uses vdpau (would not require a custom VLC build if I understand correctly).

So far I'm having no modules, I guess it's because I need a patched kernel (patwood's?) ? (quite a *nix noob, sorry). Or can it be done in userland with https://github.com/linux-sunxi/cedarx-libs ?

Tried to replace the uImage with the one from patwood's A20-kernel-3.4.79.tar.gz but I did not see a change. Would really like to have a link to a tutorial on this, so far I haven't found that.


Thanks!

You have to manually add a new user first, this link should help you: http://askubuntu.com/questions/216621/how-to-add-user-to-separate-filesystem-armel
