Bug Report Video Capture devices not appearing in 64-bit

carbonFibreOptik · Jul 28, 2013

I've been using OBS for a few versions and with the latest one I recently got an AVerMedia Live Gamer Portable. I've used a webcam previously and had no issues, but as I've only used my LGP with the latest stable build (v0.542b) I'd like to note that this could be for all versions or simply the latest.

Anyway, when adding a Video Capture device and then trying to select the device from the drop-down context menu 'LGP Stream Engine' (as well as an 'FFsource') only appears on the 32-bit edition of the application. In 64-bit I only get a partial list ('Video Camera', 'Dxtory Video 1', etc) and the other two sources are absent. This is a real bummer as I drop from ~50% CPU usage for 32-bit OBS to ~20% when streaming in the 64-bit version. I'd love to replace the Game Capture with my LGP to save processing power for the games I play, but it's almost pointless in the 32-bit version.

My suspicion is that the OBS application only supports certain device drivers. My LGP for instance might only use 32-bit drivers and the 64-bit application therefore doesn't register the device. However, the 32-bit driver should still be accessible in a 64-bit environment, so I'm not sure if maybe the issue is a simple check for all devices or a software switch that's just not enabled. For instance the 64-bit versions of Adobe apps like Premiere detect and use the LGP just fine, so the compatibility is there even if it needs to be activated.

Thanks for reading my issue guys, and super-duper-double-whammy thanks if anyone has a workable solution. I appreciate the help.

For reference, here's the last 64- and 32-bit run-time logs:

I just tried out a few previous versions of OBS and the same thing happens. 32-bit detects all devices, 64-bit is missing a couple.

dodgepong · Jul 29, 2013

Not all devices have 64bit drivers, so they won't all appear in the 64bit version.

Lain · Jul 29, 2013

Yes, this is generally the fault of device manufacturers who do not make 64bit directshow filters, not OBS.

carbonFibreOptik · Aug 1, 2013

Cool, I got in touch with some techies at AVerMedia and they said they didn't think a 64-bit driver would be an issue so they never made one. Once they found out that there is indeed a 64-bit edition of OBS (which is basically what the Stream Engine software was created for in the first place) they said they could easily churn out a 64-bit driver in the next driver update. Gotta love a company that listens to its customers, eh?

Oh, and I found out that Adobe apps convert data streams via a 32-bit bridge app that links all their apps together, hence why the 32-bit device worked in that particular set of 64-bit apps. The more you know! (Garnish with rainbows to your liking and serve.)

Thanks for being as helpful as ever guys, and keep up the solid work Jim. Nothin' but respect. :3
