Hey everyone, I'm having a very hard time finding out whats causing this stutter with DTS passthrough. I've tried all the codec combinations I can think of. Currently I have SAF 6 with ffdshow DXVA, with ffdshow audio decoder running. I've tried Spdifer, Ac3filter, LAV, and obviously ffshow. If passthrough is enabled, I get a stutter. CPU utilization is under 25% the entire time, plenty of rm available, etc. If passthrough is disabled, then it works fine. I had passthrough working just great, but I had to reformat and ever since then I can't get it to work. Any ideas?

Please post screenshot from graphedit when playing stuff and from audiosettings.
Graphedit is a part of SAF, you'll find it in tools. Pull the movie over in graphedit.

Here's a screenshot of graphedit, which audio settings did you want a screenshot of?

Ac3filter as you're using it


Edit: however i would be better to uninstall everything and use SAF. the lavfsplitter, audio decoder etc. is the way to go from now.

Here's AC3filter, funny thing is that when I'm in Mediaportal, ffdshow is used; at least the icon is on the taskbar while the movie is playing.

here's ffdshow:

I don't think that MP is using ac3filter, because it is set to passthrough, which is not happening at all. If I set it to passthrough in ffdshow, it will passthrough, with the stuttering of course.

Ok, then instead play a movie in MP and then swap out of it, Alt+tab and open graphedit > file > connect to remote graph and show us which codecs are used when you play in mediaportal.


Well you don't have passthough enabled in ffdshow.

 

[booba5185]

In order for a movie to play (withoutstutter) I have to have passthrough disabled. I'll enable it for this screenshot though.

this was when passthrough was enabled through ffdshow.

Ok.. Shouldn't happen. I remember having same issue, but not how i fixed it.(perhaps you have a bad svn version?)

The easiest solution would now be to uninstall every codec you have and then install SAF6 https://forum.team-mediaportal.com/codecs-331/saf-v6-00-based-lavf-95635/
Please set settings acording to the screenshots and during install tick use passthrough. Should be more or less obvious how to do it.


Let me know what happens then.

 

[booba5185]

I have tried that numerous times, but I will try it one more time just to be sure.

Yeah, well something is wrong with your merits. And SAF does not use ffdshow nor AC3filter for passthrough any more.
