Bug Report OBS Crashing on Preview

[alterity93]

Hello,

I have recently been trying to use OBS to stream wii games, however every time I enable my video capture device under sources and then press preview stream, OBS crashes.

I searched on the forums and on google and I could not find the same issue as my own, only similar ones. I tried some of the solutions that I could find but none helped.

Here is the crash log:

OBS has encountered an unhandled exception and has terminated. If you are able to
reproduce this crash, please submit this crash report on the forums at
http://www.obsproject.com/ - include the contents of this crash log and the
minidump .dmp file (if available) as well as your regular OBS log files and
a description of what you were doing at the time of the crash.

This crash appears to have occured in the 'c:\program files (x86)\obs\plugins\dshowplugin.dll' module.

Hey there iw as having this issues just now and seem to have fixed it. i had two scenes running one for my game the other for my webcam i disabled my webcam and hit preview and it worked just fine, there may be an issue with it trying to run two scenes simultaneous.

Thanks for your input, but unfortunately when I hit preview, I only have 1 scene running (not 2 or more) which is the game.

This might be useless...
but have you tried running the program as administrator? I know some programs if you don't run as admin, it won't work properly (TCP Optimizer as an example).

Just tried it, no luck :(.

This is caused by your webcam or some device. Probably something related to the drivers (though don't quite know for sure). Try selecting different values in "Set Output Format" in the properties of your device capture source.

I'm not sure where the "set output format" option is, I am not able to find it. I checked the properties of my device in control panel and I also checked "configure" on OBS.

However, I did make a small discovery which was if I switch the "video standard" of my device to NTSC 433, apply it, preview stream, then switch it back to NTSC_M, the stream works. However if I make any further changes to the capture device settings, (except if I do edit scene, that is fine) OBS crashes.

"Use Output Format" can be found in the properties of the Video Capture Device:

It's the only thing I've got at the moment.. I know the function in there doesn't have a bug, so I'm just really confused at why that would be happening

Thank you Dodgepong for the visual, I checked off that option and my stream seems to be working great! Thank you for the help as well Jim.
