This section provides a guide to obtaining, installing, and testing the GstQtOverlay evaluation version.

Step 1: Request the Evaluation Binaries

RidgeRun provides a fully-featured evaluation version of the plugin with a limited processing time, as shown in table 1:

Feature Professional Evaluation
GstQtOverlay Element Y Y
Unlimited Processing Time Y N (*)
Source Code Y N
Table 1. Features provided in the evaluation version

(*) The evaluation version will limit the processing to a maximum of 10 000 buffers (5 mins at 30fps).

In order to request an evaluation binary for a specific architecture, please Contact Us by providing the following information:

  1. Platform (i.e.: i.MX6, Xavier NX, etc...)
  2. Target Qt version
  3. GStreamer version and kernel version, you can provide the output of the following commands:
gst-launch-1.0 --gst-version
uname -a

Step 2: Install the dependencies

Make sure the dependencies are fulfilled, for this check our Dependencies section before moving to the next step.

Step 3: Install the Binaries

RidgeRun should've provided you with a .tar package: gst-qt-overlay-1.Y.Z-gst-1.X-P-eval.tar. Copy the files into your system:

tar -xvf gst-qt-overlay-1.Y.Z-gst-1.X-P-eval.tar
sudo cp -r gst-qt-overlay-1.Y.Z-gst-1.X-P-eval/usr/lib/* /usr/lib/


You can now test the plugin installation as described in our Checking GstQtOverlay Install section.
