video freezes, audio continues

[Cell05]

Hey everyone, i have a problem with a video of mine. its a mpg and when you click on the bar to skip to a certain part of the video, the video itself freezes in the place it left off and the audio contines to the place you clicked on. Its hard to expain really, the video itself stops and the audio keeps playing as you skip to certain parts. Anyone know hwo I can correct that video malfunction?

What player are you using ? Windows Media Player is a poor quality player when it comes to seeking through video. I would suggest using something like MPC or VLC.

If the problem persists in other players, then the video itself has a problem. It could be corrupt, it could be the way it was encoded.

Hi, i think i have the same problem. The audio continues but the video freezes. This happens after a conversion to mpg with tmpgenc and im using divx, vlc. It used to work perfectly but i had to unistall the program and now it's not the same, What could be the problem?

I had the same problem. I think mine was caused by a conflict between the native windows MPEG decoders and the Abode MPEG encoders that got installed after I installed Adobe Premiere. I just used DirectShow Filter Manager to look up all the entries for MPEG and MPEG-1 codecs and I removed them. The native DirectShow codecs can be reinstalled by going to the "Troubleshooting" tab and clicking restore. It solved my problem and now all my MPEG files playback without any problems.

That sounds exactly right.

"Seeking" in DirectShow requires that all the filters (e.g., file reader, MPEG video decoder, audio decoder, video renderer) support the seeking properly. The default DirectShow MPEG 'parser' (the filter that splits the MPEG into video and audio) supports seeking. Other MPEG decoders don't. If one part of the DirectShow 'graph' supports seeking and another doesn't, then some of it will seek (e.g. the audio) but the other won't (e.g., the video).

If you want to read all about it (!), have a look here: http://www.gdcl.co.uk/articles/Parsers.pdf (the author was the original architect for DirectShow)

I've recently come across this seeking issue with an application under development.
