[vlc-devel] [PATCH] Reshuffle after playthrough

It looks like i found the correct points to insert my code, now it seems
quite obvious to me. The patch is attached to this mail (again) and I
already did some testing. You can find the results here:

https://gist.github.com/W4RH4WK/6827230

This patch shuffles the playlist ether when it automatically advances and
reaches the end, or when the end / beginning is reached by using next /
prev. The Gist shows the according log output for each of the 3 cases. You
can observe reshuffling after all songs have been played exactly once.

Might this patch work for you and resolve this issue? ;)
