How to sync audio and video with WDM driver
« on: August 10, 2018, 12:06:15 pm »

I am using convolution and noticed that while watching movies from MC's library everything works fine, as soon as I use the WDM driver, the sound is way off from the video. Is there a best practice approach to sync the two streams?

You cannot really perform operations that have a large latency like convolution when using a live source like the WDM driver when you rely on A/V sync. The video is being handled by another application, so there is no chance for MC to influence the sync. The only option would be if that other application lets you configure sync.

Thanks Hendrik for the quick reply. I did not work with Zones yet, but could I create one zone for WDM with convolution off and one zone for playing from MC's library with convolution on?

Yes, that would work.

Thanks again Hendrik. I set it up and will test how it goes.

Am I right to assume that I need to add two rules to Zoneswitch? I have one rule that says if the filename does not contain "ipc" -> stop playback in WDM Zone and start in Player Zone and another rule that says if the filename does contain "ipc" -> stop playback in Player Zone and start playback in WDM Zone. Is there some more elegant "if" statement possible to add as a rule?!

The suggested setup and zone switch rules are on the Wiki page:
https://wiki.jriver.com/index.php/WDM_Driver

Basically, its recommended to use Name for matching instead of file name.
