Question / Help OBS Studio crash after starting C920 video capture

[K3nnyk3]

Hi all!

Im using the latest OBS Studio and worked very well for 3 month. Now when I want to change the properties of my Logitech C920 the whole software crashes. I tried with the classic OBS, it works there without error. Also tried the 32,64 bit studio, in administrator mode and without and 5 different version all of them gave the same crash in the same time. Adding video capture, right click, properties and crash. Already tried the driver reinstall, but the webcam works like a charm with anything but OBS Studio.
Anyone have any suggestion?

Here is the crash log hope it's help:

I have a C920 and I'm not quite getting the same issue. The crash log is a bit baffling -- are you attaching some audio output via the "Use custom audio device" option in the properties of the source? Because the crash seems to be coming from some sort of audio from a device source.

The C920 doesn't have any default audio output, which is why I ask. It's only video unless you explicitly attach audio via that option.

Thanks for the quick anwser. I can't change the properties of the webcam cuz I'm getting crash immediately. Tries to turn off everything in the audio section bit still not working. As I see there is no audio option in the webcam driver so I pass that.
Getting this but I think it's the same content:

So you're able to start up the program, right? You just can't add the source. What other devices do you have on the system? I'm not sure if this is caused by the webcam.

Yes the program start up and every function working exept change the C920 properties. Tried to plug out every other device just the mouse and the webcam was plugged in but still tha same. Also tried another port. (all of them)
Tha strange part is the webcam working well in the classic

I send you a PM with a build to test. Let me know when you have time to test it out, tell me whether that works or not.

This was indeed a bug that I haven't seen until now -- it's fixed in the next version. Commit: https://github.com/jp9000/libdshowcapture/commit/1d36ea4

I made a quick build of it in case anyone needs and posted it on my fosshub page here: http://code.fosshub.com/OBS/downloads -- it's the OBS-Studio-0.14.2-24-g3deae76.zip file. You'll still get update notifications with this build if 0.15.0 comes out, in which case you'll want to of course upgrade to when that happens. The build is signed with my code certificate. If you are reading this at a later time and the file not there, then that means 0.15.0 or above has come out and replaced it already.
