SeiExtract Element	Y	Y
SeiMetatester Element	Y	Y
Unlimited Processing Time	Y	N (1)
Source Code	Y	N

(1) The evaluation version will limit the processing time to a maximum of 5 minutes.

Evaluating the plugin

Dependencies

First, make sure the dependencies are fulfilled:

sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev gstreamer1.0-plugins-base libgstreamer-plugins-bad1.0-dev gstreamer1.0-plugins-bad

Eval Binary Installation

To use the binary provided by RidgeRun, export the location of the evaluation binary in your environment.

export GST_PLUGIN_PATH=${GST_PLUGIN_PATH}:/path/to/evaluation/binary/

where /path/to/evaluation/binary is the location in your file system where you have the binary provided by RidgeRun.

Additionally, you may just copy the binary into the standard GStreamer plugin search path.
