DS Video DeSync issues

[Cyberia]

First, a BIG thanks to Shodan for the recent additions to DirectShowSource!

In playing around along these lines I have discovered a nasty issue.

I attempted to seek backwards in a (DirectShowSource loaded) mpeg file. When I did, the video continued from where it was currently playing, and the audio dropped out entirely. However, I when I stopped the mediaplayer, then played again from the beginning I get a "Video DeSync" message.
Worst of all, mediaplayer is now hosed and you must actually reboot to recover it.

So I am guessing that "Video DeSync" somehow seriously gums up DirectShow itself.

Actually, you just have kill the wmplayer.exe process, but its still bad.

Backwards seeking is not possible with DirectshowSource.

You could try specifying DirectshowSource("fdkjhf.avi", seek=true). In all cases I have tried it fails (hangs).

Use DSS only if you cannot open the file in any other way.

Shodan, I have the utmost respect for you and the work you have done, but how can this be? Every player I use allows seeking forwards and backwards. I'm pretty sure mediaplayer (at least) uses DirectShow. Granted not all formats allow seeking (asf) but some do, are you saying that every player implements specific decoders for various formats? I though that was the point of DirectShow...ask the OS to decode the clip.

I am extremely grateful for the recent work you have done to DSS! I'm not trying to say this in a bad way, so please don't think this is an attack, but could it be this is an indication that DirectShowSource needs further work?
