Skip delay audio/video sync

visteon · 2008-06-01, 18:19

When using the time skip function (to skip adverts) in recorded TV, quite often there will be a delay before the audio / video are both in sync again.

It can be either that the audio or video is playing but the other is not. They will usually come good after some period of time 10sec+ to minutes.

Doing a skip of 30sec one way and then back will often bring them back immediately.
This has been a minor but annoying problem for months now.
Has it been noticed by others and/or reported.

I am using SVN 19158

We need to know the sytem specification you have, which MediaPortal you are using(TV Server/TVPlugin + MediaPortal or MediaPortal old TV Engine), also atach logs to your post.

I had the same problem using Ac3filter, ffdshow or Microsoft codes, check here Tv with ac3filter and seek problem

I found the fix using Nvidea codec for Audio on TvSecttion... With Nvidia codec for audio no problems.. but with the rest I got sync problems.. Also this is only happen with skip. If I use FF no problem with any of the codecs.. strange..

Thanks iosub for the pointer to AC3Filter.
This does indeed seem to cause the problem.
More specifically when the 'use SPDIF' option is checked.

This is a shame as I really like the options in AC3Filter for Dynamic Range Control and SPDIF encoding.
Does anyone knows why this happens?
