DirectShow: This driver is optional, only needed for these software which control the camera through DirectShow. Change Log: Released 9/18/2020. TWAIN: Implemented with our camera, regulates communication between software and digital imaging devices.
- May 23, 2020 Our website provides a free download of DIRECTV 2.0.1 for Mac. This free Mac application is a product of Directv, Inc. Our antivirus scan shows that this Mac download is clean. The program is included in Audio & Video Tools.
- As of this announcement, the Hap video codec family can now be natively used on Windows in TouchDesigner, OpenFrameworks (via ofxHapPlayer), Jitter (via jit.gl.hap), DirectShow and Unity (via RenderHeads AVProQuicktime), with support coming very soon to D3 Media Servers and the Isadora programming environment.

We on the OBS team thank CatxFish for their hard work on this plugin.
This plugin provides a directshow Output as a virtual webcam .
How to use:
Output:
1. Selecting Tools -> VirtualCam
2. Press start button and close diailog
3. Open your 3rd party program and choose 'OBS-Camera' as a Video input
Filter:
1.Add a filter to the source you want to output to the camera
2.Choose a sink camera target then press start button
3.If this camera is not occupied , the start button will change to stop button .
4.Open your 3rd party program and choose 'OBS-Camera' as a Video input.
How to Install without installer:
1.Go Github Release to find zip file
2.Unzip OBS-VirtualCam2.0.1.zip and put it to your obs-studio install folder
3.Run CMD as Administrator and register 32bit directshow source
ex: regsvr32 'C:Program Files (x86)obs-studiobin32bitobs-virtualsource.dll'
4.Do it again to register 64bit directshow source
ex: regsvr32 'C:Program Files (x86)obs-studiobin64bitobs-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 useregister 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)

The latest development versions of Speex and SpeexDSP are always available through Git. Note that packaging information for Debian can be found on the packages page. In addition, RareWares maintains useful Windows utilities such as SpeexDrop.
Current Stable Release (recommended)
Speex 1.2.0
This is the latest stable release of the Speex codec library.
Downloads:Current Unstable Release (recommended)
SpeexDSP 1.2rc3
This brown-paper-bag release adds two headers that should have been included with SpeexDSP 1.2rc2. These are needed to build the resampler with NEON optimizations and to build SpeexDSP without the Speex codec library.
Downloads:Speex 1.2rc2 and SpeexDSP 1.2rc2
This release splits the speex codec library and the speex DSP library into separate source trees. Both projects received build-system improvements, bugfixes, and cleanup. The speex codec's VBR tuning was improved, while the speexdsp resampler got some NEON optimizations.
Downloads:1.2rc1
This release adds support for acoustic echo cancellation with multiple microphones and multiple loudspeakers. It also adds an API to decorrelate loudspeaker signals to improve multi-channel performance. In the bugfix department, there are fixes for a few bugs in the echo canceller, jitter buffer and preprocessor. At this point, the API for 1.2 should be stable and only a few very minor additions are planned.
Downloads:1.2beta3
The most obvious change in this release is that all the non-codec components (preprocessor, echo cancellation, jitter buffer) have been moved to a new libspeexdsp library. Other changes include a new jitter buffer algorithm and resampler improvements/fixes. This is also the first release where libspeex can be built without any floating point support. To do this, the float compatibility API must be disabled (--disable-float-api or DISABLE_FLOAT_API) and the VBR feature must be disabled (--disable-vbr or DISABLE_VBR).
Downloads:1.2beta2
Again, this new releases brings many improvements. The RAM requirement for wideband has gone down drastically (i.e. more than 2x). A new resampler module has been added, providing arbitrary sampling rate conversion -- fast. The echo canceller has also been improved. A bug in 1.2beta1 that made the echo canceller unstable has been fixed. The echo canceller should now converge faster, be robust and tolerant of incorrect capture-playback synchronisation. The preprocessor has also been greatly improved. Not only should the quality be better, but it is now fully converted to fixed-point. At last, early TriMedia support (incomplete) has been merged.
Downloads:- No Windows binaries -- looking for a maintainer
Previous Stable Release (old, not recommended)
1.0.5
The main change with this release is that it includes API additions from the 1.1.x branch (while being backward compatible), so that transition from 1.0.x to 1.1.x can be made easier.
