First draft implementing audio output in GStreamer:
- Only left channel works
- Has a big audible sound lag (timing issue)
- Retarting or changing movie/audio file stops sound
Removed useless things from VideoInput
Bug fix (issue #24): QT threads related error when running in release
Duration and timestamp seem to be useless so I'm removing them for now
Verify buffer discontinuity
Remove useless crap from _audioPull()
