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.

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from './bin/data/test1.mov':

Test 2

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

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from './bin/data/test2.mov':

Unsupported codec with id 0 for input stream 2

Test 3

Works well.

Input #0, avi, from './bin/data/test3.AVI':

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