oxfOMXPlayer - load movie in thread?

Tried using a thread to load a movie into an ofxOMXplayer ,but as soon as i do this the app quits with a seg fault.( I can stop and start a movie ok, but no loading.)

Anyone actually achieved this?

Tried async load with the regular ofVideoPlayer which works sometimes but has random app. freezes
which seems to be an ongoing issue on PI.

RPI 3 of 0.9.8 Jessie.

TIA
