RTSP streams play in VLC, but only output audio in Quicktime
Posted by on 16 March 2012 10:35 AM

If your RTSP stream from a Haivision Makito/Barracuda encoder plays in VLC, but is audio only in Quicktime, it could be that you have Direct3D video acceleration enabled in QuickTime and your graphics card does not support this feature.

To disable Direct3D acceleration please follow the steps below.

  • Open Quick Time
  • Click on 'Edit'
  • Select 'Quick Time preferences' under 'Preferences'
  • Under 'Advanced' tab uncheck the box next to 'Enable Direct3D video acceleration'
  • Click on 'Ok'
You should now be able to decode both audio and video within QuickTime, if not please contact our support team via the helpdesk for further assistance.
