some clearification bout 'at some point':
I'm playing the same file (big bug bunny 1080p) over and over again and after
the 3-5th loop the screen gets dark and the application becomes a zombie.
Just tested with the new kernel, I only got memory-error twice and could just
continue playing with 'trying again'
One addition from wandsolo:
I just finished my wandsolo build and this error happens as soon as I try to
play anything with 1080p. It's working with 720p.
Any advice?
Maybe it's related .. maybe it's just '512mb isn't enough for 1080p' .. but
that would be surprising, wouldn't it?
The gstreamer error:
[ERR] mem allocation failed!
and as kernel error:
