Spout Updates Its Video Sharing Tool for Windows Apps: Expanded Transparency Testing, Image Capture, and Recording

On October 11, Spout, an open-source tool for sharing real-time video
between Windows applications, announced the release of version 2.007.018.
The included sender and receiver demo programs have been updated
with transparency testing, image capture from received video,
and expanded video recording.
Changes have also been made to the SDK for developers.

What Is Spout: A Tool That Connects Multiple Video Applications

Spout uses the graphics card to pass real-time video
between applications on Windows.
The official website states that it works with near-zero latency or overhead.
It is provided free and open source,
and the website explains that it can share video between applications
such as Resolume, Processing, MadMapper, and TouchDesigner.

As an example, the website describes creating graphics in Processing,
mixing them in Resolume, and projection mapping them with MadMapper.
It is a mechanism for connecting video created in one application
to processing in another.

What Changed: Transparency Testing and Capturing Received Images

With this update, both the sender and receiver demo programs
now allow transparency testing.
The receiver demo also adds the ability to copy images to the clipboard.

Received images can be saved as timestamped image files
or saved with a file name and type of the user’s choice.
In addition to viewing results on screen,
users can now capture them as still images.
These are described as updates to the included demo programs.

Recording Is Also Available as a Standalone Application

The receiver demo also adds an option to open a video recorder program.
It can record the currently received sender or any other sender that is running.
The recorder is a standalone application
that can be used independently or launched from within a program.

The developer says many changes have also been made to the SDK source code.
The changes are documented within each file,
and an update summary can be found via the GitHub release page.
The same page also provides the version 2.007.018 release files.

LC Signal’s Perspective: More Ways to Check and Record Shared Video

This update adds transparency testing, still image capture,
and a way to launch a recorder to the included demos.
Beyond connecting video between applications,
it makes it easier to capture and check received results.
It seems likely to help with checking work
when combining multiple video tools.

The fact that the recorder can also be used on its own is straightforward.
After confirming a connection with the sender and receiver demos,
users can move on to recording the video they need.
