When watching video and sending the audio using Airfoil to an Airport Express there is a 2-3 seconds delay in the sound.

In VLC it's possible to change the video/audio sync. Is there a more generic way of doing this on a Mac? So that you can watch any kind of video (Flash, Quicktime etc) in a browser and send the audio to your Airport Express?

Is this not what the Airfoil Video Player seeks to address: delaying the video displayed locally to compensate for the audio delay?

(If there's a video format it doesn't support that you really want, let Rogue Amoeba know!)

Is possible to replace the embedded qt-player with qt sync? And how about other embedded plugins such as flash, java etc? – D. Wroblewski Jul 30 '09 at 10:45

the link explains how to install the standard quicktime player or the quicktime alternative as a plugin not qt sync. – D. Wroblewski Jul 30 '09 at 13:29
