But I would recommend using the ones from: https://github.com/ayufan-pine64/linux-build/releases/ (0.6.2 is currently considered stable)yes, i will stick with these for the time being.
I realize that smooth media playback really is the most important issue for me.
From above, I tried the stable release first (flashed to microsd with pine64-installer, and installed from there), but upgraded to the latest pre-release pretty much straight away.
i noticed some changes (slight improvement). chromium plays back video much better now, but the overall performance impact still seems to be much larger than necessary (choppiness even at 480p, and the user interface crawls to a near-standstill during video playback).
smplayer does not play youtube video at all, local video plays only sound.
i installed mpv (my media player of choice) and it complains & segfaults on local and youtube video:

i also installed armagetronad, a game that is good for testing opengl abilities. it starts up but uses software rendering i guess (performance is abysmal on normal settings), i see the same error as with mpv:
Code:MESA-LOADER: failed to retrieve device information
libGL error: unable to load driver: sunxi_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: sunxi
so is this a question of configuring things properly?
or do applications need to be compiled with support for this gpu?
PS:
I tried to reinstall the 0.7.8 pre-release from scratch (instead of updating from 0.6.2), but failed twice:
- dd'ing the .img to microsd, it did not boot at all. just blinking green led, until i remove the card
- pine64-installer doesn't run on pinebook
so how do we create the bootable images manually?
I would stick to 0.6.2 for now. You can get pretty smooth playback in SMplayer - see my SMplayer tweaks thread.
