Bug Report Problem with OBS - 32bit, and unable to use elgato and webcam at same time?

[Kelvin]

I am running a 64 Bits windows, but i am forced to use 32 bit because 64 bits obs cant detect elgato.

So at 1st it was working then after i manage to tweak it to work (didnt mod and file), so i went to close and shut down my computer. Next day when i open the 32 bit version i get this problem?. My 64 bit on the other hand is fine

Seems to be working but currently having WOOOPS crashing when i try to add my webcam Global Source.??

So summarize is only can stream gameplay but my webcam cant be detected on 32bit version

gameplay cant be detected but webcam can on 64bit

 

[R1CH]

Can you post your regular OBS log too?

 

[Kelvin]

Ok i troubleshoot and have that my webcam is causing the problem?

Edit: my webcam only works when on 64 bit version?

 

[Kelvin]

Is the dump file the log? If so here it is - https://www.dropbox.com/s/zr27iijsct7drgn/OBSCrashDump2014-06-13_38.dmp

it stops at powrprof.dll?

 

[R1CH]

The log files can be found in Help / Log Files

 

[Kelvin]

ok here you go https://gist.github.com/b14a6d48cb0184862a64

 

[R1CH]

Thanks, the log confirmed my suspicions. This crash will be fixed in the next version of OBS. In the meantime, it seems your problem occurs because your USB bandwidth may be exceeded. Try lowering the resolution of the webcam or moving it to different USB ports.

 

[Kelvin]

Ok thanks you, great program by the way, extremely user friendly (at least to me) :)

 

[Kelvin]

Tried different USB port 2.0 and 3.0 (i know no diff) , front and back ports at my lowest camera setting 160x280?

Guess i have to wait for next version then :(

 

[R1CH]

The next version won't fix the issue, it will only prevent the crashing when the device fails to initialize.
