VLC lag

Postby davbren » 19 Aug 2006 18:33

I've been experienced some jumpiness whilst watching DVDs, it doesn't happen that often, maybe a couple of times a movie but its enough to be annoying.

Try shutting off the skip frames option in preferences video. Open your task manager and check CPU usage both before playing the DVD and during play. VLC should show no CPU usage. Open Messages. Assuming an undamaged DVD the messages file should be quiet.

All digital video is follow audio for sync, so if this is not happening properly it is generally an audio driver or card problem.

VLC is drifting between 2 and 18% CPU usage, I am running ripped DVDs from my hard drive. I've turned the frameskip option off and still i get the ocational skipping in video. Theres nothing in the messages folder.

Unlike many other players the DirectX hand off for MPEG 2 to your video card is complete. There should be no increase in CPU usage except when making changes. Try updating your video card drivers and perhaps a newer version of DirectX runtime (6/06).

Audio card jitter and or clock drift is seen in messages as buffer timing problems where the sync is being corrected or the sound is being resampled. But if your sound drivers are old it wouldn't hurt to update these too.

I would expect you should see the same thing running a commercial DVD from your optical drive. If not, the issue could be fragmentation problems.
