A Gstreamer plugin to control the PDA of the Optimum 2M module and produce a csv file with all sharpness asociated to PDAs

The following libraries are required for this plugin.

• v4l-utils
• libv4l-dev
• libgstreamer1.0-dev
• libgstreamer-plugins-base1.0-dev
• meson

sudo apt install v4l-utils libv4l-dev libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev meson

First you must make sure that your device's clock is correctly setup. Otherwise the compilation will fail.

In the gst-sharpness folder do:

meson build

ninja -C build

sudo ninja -C build install

First you must make sure that your device's clock is correctly setup. Otherwise the compilation will fail.

In the gst-sharpness folder do:

To test if the plugin has been correctly install, do:

export GST_PLUGIN_PATH=/usr/local/lib/gstreamer-1.0/
gst-inspect-1.0 sharpness

If the plugin failed to install the following message will be displayed: "No such element or plugin 'sharpness'"

''' sudo rm /usr/local/lib/gstreamer-1.0/libgstsharpness.* '''

By default the plugin is installed in /usr/local/lib/gstreamer-1.0. It is then required to tell gstreamer where to find it with the command:

export GST_PLUGIN_PATH=/usr/local/lib/gstreamer-1.0/

The plugin can be used in any gstreamer pipeline by adding '''sharpness''', the name of the plugin.

With fake image pipeline:

gst-launch-1.0 videotestsrc ! sharpness ! videoconvert ! ximagesink

With simple video stream:

gst-launch-1.0 v4l2src ! sharpness ! queue ! videoconvert ! queue ! xvimagesink sync=false
