win-dshow.dll crash

[Goafterthat]

Hello, any chance some of you use a HDPVR with OBS ?

It is recognized by OBS, it works for a second up to a few seconds, then it "whoops" and fatal error.

From what I get OBS try to divide by zero when it receives the signal. I try to restart everything, I try replacing win-dshow.dll thinking it might got corrupted somehow. Nothing worked.

If it was a compatibility problem I would just have a black screen or no screen at all. Here it works for a bit before crashing so I'm puzzled.

Hey it's me again. Spent a good part of my sunday trying to figure out this stuff...
Good news is I don't think the win-dshow.dll is the issue after all. I've found a way to tweak around the fatal error, so you have to go to the properties of the Video Capture Device you're using (here HDPVR), change the Audio Output Mode to "Output desktop audio (DirectSound). Don't let it on Capture audio only.
THEN, check the "Use custom audio device" box, sadly my only choice is "Microphone".

This will allows the video flux to pop-up (may take a few seconds, I don't know but you should see the HDPVR working.) But with this, I don't have any sound other than my microphone... Still trying to figure out how to get the device's sound. If I don't come back and no one else figure it, good luck.
