How can I fix lagging sound in when playing videos?

Question

Sometimes, when I am playing a video, the sound lags the video by a bit (±2 seconds is not unheard of). Is there a player that can go two seconds ahead on the audio, or two second behind? It would need to be able to play .avi and .flv files.

Answer 1

VLC has the option to change the audio delay. While there isn't a menu shortcut for this (I didn't even find anything related to "synchronization"), you can do it with the keyboard:

• f decreases the audio delay
• g increases the audio delay

The shortcuts can be changed in the Hotkeys section of VLC's preferences (should be the same for Windows, can't test right now).

While this masks the effects of lagging audio, it of course depends on the cause of the lag if that's a solution you can live with. If the video stream itself is delayed, you could re-wrap it in another container and fix the delay.

Answer 2

VLC can do it, and is the best media player out there.
