Image generation elements

• edtpdvsink: Video sink for EDT PDV Camera Link simulator
• gigesimsink: Video sink for A&B Soft GigESim GigE Vision simulator
• pleorasink: Video sink for Pleora eBUS SDK GigE Vision transmitter

Other elements

• extractcolor: Extract a single color channel
• klvinjector: Inject test synchronous KLV metadata
• klvinspector: Inspect synchronous KLV metadata
• sfx3dnoise: Applies 3D noise to video
• videolevels: Scales monochrome 8- or 16-bit video to 8-bit, via manual setpoints or AGC

Dependencies

• GStreamer 1.2.x
• Specific frame grabber SDKs and/or licenses

Installation

• Install GStreamer 1.2.x or newer (latest should work)
• Build project or download a release from Github (ZIP files under Assets)
• Extract files somewhere
• Create an environment variable GST_PLUGIN_PATH that points to where you extracted the files

Examples

Capture from a CoaXPress camera via a Kaya Komodo frame grabber, apply AGC to convert it to 8-bit monochrome, then output the video via A&B Software GigESim which generates GigE Vision video:

gst-launch-1.0 kayasrc ! videolevels auto=continuous ! gigesimsink

Then in another command capture the GigE Vision video via Pleora eBUS and display the video to the screen:

gst-launch-1.0 pleorasrc ! autovideoconvert ! autovideosink

Compiling

• Install Git or download a ZIP archive
• Install CMake
• Install GStreamer distribution or build from source. The installer should set the installation path via GSTREAMER_1_0_ROOT_X86_64 environment variable. If not set, set GSTREAMER_ROOT to your installation, the directory containing bin, lib, etc.
• Install any camera or framegrabber software/SDK for those plugins you wish to build. Check cmake/modules for any paths you may need to set.
• Run the following commands from a terminal or command prompt, assuming CMake and Git are in your PATH.

git clone https://github.com/joshdoe/gst-plugins-vision.git
cd gst-plugins-vision
mkdir build
cd build
cmake -G "Visual Studio 15 2017 Win64" ..

• To create a package of all compiled plugins run:

cmake --build . --target PACKAGE
