ofVideoPlayer won't play full audio

Hi,

I’ve just tested videoPlayerExample with different videos (with audio channel). Sometimes the audio stops after a few seconds.

I’m on ubuntu:

Distributor ID:	Ubuntu
Description:	Ubuntu 14.04.5 LTS
Release:	14.04
Codename:	trusty

#Test 1
Audio stops after 2 seconds.

#Test 2
Audio stops almost immediately (but, as it is Prores, maybe this is the deal)

Is there a preferable codec for ofVideoPlayer (I assume mjpeg) and/or is this a bug ?

ofVideoPlayer in linux uses gstreamer which is the same library the default gnome video player, totem, uses so any video you can play by double clicking on it in ubuntu should play fine in OF, not sure what might be the problem with the sound but i doubt it has to do with the video codec and probably more with the container itself or the audio format
