Bug Report Webcam buffer not working (Bootcamp Windows)

[Hexx]

Hey so I've noticed with version 0.581b and newer, setting the buffer time doesn't effect my webcam.
I'm running 32 bit OBS on 64 bit Windows through Bootcamp on a 2011 iMac. (32 bit OBS due to Elgato's lack of 64 bit drivers)
I rolled back to version 0.571b and the buffer time works great so the issue is sorted for me for now, but felt I should post to see if it could be fixed in a future version.

log file below.

Interestingly enough, in the log file it reads

23:07:49: use buffering: true - 14000000, fourCC: 'MJPG'

but as above, that doesn't seem to be working correctly.

Thanks very much :)

Hm, I just checked it on the most recent versions and didn't see any difference. It's not actually set to 14000000 milliseconds is it? It will probably most likely not work in that instance

 

[Hexx]

I had to double check to make sure I wasn't a dumb dumb, but no, it's correctly set to 1400ms.

Interestingly enough, on version 0.571b I was streaming last night and the webcam slowly but surely pulled back into real time from it's buffer...? Inherent issue with the iMac iSight camera perhaps?
Failing any surefire fix I may just have to suck it up and buy an external webcam.

Thanks for your help, Jim :)

Hm, I can't seem to replicate the issue. Could you see what happens when you set it to other values? Or see if it happens if you remove/re-add the source? I'm very curious as to what's going on there. I doubt it's some inherent issue with your computer, it really shouldn't be.
