This tutorial tells you how to run a GStreamer* video pipeline using GStreamer* plugins and display a video file in a window in the container.

Go to the AMR_containers folder:

cd <edge_insights_for_amr_path>/Edge_Insights_for_Autonomous_Mobile_Robots_*/AMR_containers

Prepare environment setup:

source 01_docker_sdk_env/docker_compose/05_tutorials/config/docker_compose.source
export CONTAINER_BASE_PATH=`pwd`
export ROS_DOMAIN_ID=31

Run an automated yml file that opens a GStreamer* sample application inside the EI for AMR Docker* container.
```
CHOOSE_USER=eiforamr docker-compose -f 01_docker_sdk_env/docker_compose/05_tutorials/gstreamer_video.demo.yml up
```
Expected output: The video file is displayed in a window in the container.
To close this, do one of the following:
- Type Ctrl-c in the terminal where you did the up command.
- Run this command in another terminal:
```
CHOOSE_USER=eiforamr docker-compose -f 01_docker_sdk_env/docker_compose/05_tutorials/gstreamer_video.demo.yml down
```
For an explanation of what happened, open the yml file:
- The first 23 lines are from the EI for AMR infrastructure.
- Line 26 clones some sample videos.
- Line 27 play the video using GStreamer*.

To use your own video, use the same yml file but update line 27 to target your own file.

For example, copy the file:

cp test.mp4 ${CONTAINER_BASE_PATH}/01_docker_sdk_env/docker_compose/05_tutorials/test.mp4

And update line 27 to:

gst-launch-1.0 playbin uri=file://${CONTAINER_BASE_PATH}/01_docker_sdk_env/docker_compose/05_tutorials/test.mp4
