ex: regsvr32 "C:\Program Files (x86)\obs-studio\bin\64bit\obs-virtualsource.dll"

Register failed during installation
It's usually due to dependency reason . There's a chance you need to install visual studio 2017 redistributable package (2013 if the plugin version is 1.x.x ), also the directshow interface needs swscale-4.dll and avutil-55.dll in you obs install directory.

FAQ:
Is it necessary to install 32bit version?
Yes, there are still many 3rd party programs use 32bit directshow interface for the reason of compatibility.

Why resolution and framerate are not same as OBS output Setting?
If you open OBS and Start Virtual Output before using your 3rd party software, the virtual webcam will set the obs setting as a default setting .Otherwise the default setting of virtual webcam will be 1920x1080 @ 30fps

Is it possible to output with portrait resolution (like 1080x1920) ?
It depends on your 3rd party software , it might reject recommended resolution.
If your software is compatible , you just need to set the obs output setting to the resolution you want.

How to prevent the drop frame issue?
Maybe your PC is too busy ,try to set more buffer.

Is there a virtual microphone ?
This plugin provide a directshow audio source which can't be recognized as microphone , only some programs like VLC can use it.

Does this plugin support other platforms?
There's a Video4Linux version . But it only contains the sink part , you have to use it with v4l2loopback.
And there's no plan on mac version.

Is the driver-layer virtual device ( for microphone) development still going?
No, there are two reasons why I decide to make it pending.
1. The development is mess and painful, an error could cause blue screen.
2. Even you finish the code , you still need a paid certificate called EV code signing to distribute your driver.


Known issues
- Skype UWP edition don't accept directshow interface , please use Skype desktop edition.
- Unity Application can't get image from virtualcam , please use register batch (reg_path.reg) in release page to manually add dummy device path .(note: The registry conflict with skype desktop , you can use unreg_path.reg to remove it)

a must if we want to use obs with 3rd party softwares
I now have the full capabilities of OBS available in Google hangouts - extremely useful.
Works with GoToWebinar. It did not work with just the 64bit version of OBS with the 4x OBS-Camera combination. Reinstalled OBS x86 and 1x OBS-Camera options; then it showed up as a camera option in GoToWebinar.
Very nice, can finally use this feature in OBS after several years of hoping it would show up. Very useful for google hangouts or any other service where webcam inputs are used. provides a low-lag solution for screensharing that just can't be matched by certain implementations
Once I get a clients show going I can switch this on and they can see what they are doing in real time. A fantastic solution for a problem that's been nagging me for over a year!
Now, Here's a challenge for the developer... Make an app that allows your phone, (iPhone or Droid) through a USB connection to pick up that camera. Then OBS users could stream to Instagram, and you would be crowned kink of Plugins.
This little plugin saved my butt recently when a client required me to stream multiple audio and video sources to Kickstarter Live. For them as ain't used it, KSL forces you to use a (badly built, bug-ridden) browser-based encoder that can only recognize one audio and one video source per broadcast.

OBS Virtual Cam provided an excellent workaround to that, although KSL makes you jump through a few extra hoops before you finally get everything working.
Super useful for so many things! Keep up the great work!
Thanks you for this master piece of software.
With this... Now OBS is better than XSplit.
This provides functionality I've seen requested often, and it's something I've used a fair few times over Discord and Skype. A really customizable way to send your OBS video across the internet to people without having to stream to a service like Twitch. Loving how often it gets updated, too!
Very usefull for set multiview scene. Thank you very much.
