Introduction

This article documents the usage of the Maivin GStreamer Docker container for various workflows, our example will demonstrate streaming H.265 video over TCP to a PC running VLC.

Requirements

• Torizon for Maivin BSP 5.7.1.1 or newer.
• VideoLAN Client "VLC" installed on PC

Usage

The maivin/gstreamer container provides the integrated Gstreamer environment along with NXP extensions to support the various hardware components found on the Maivin platform.  By default a stream.sh is bundled and launched as the default entry point.

docker run -it --rm --privileged -p 9000:9000 maivin/gstreamer

On the VLC side select Media->Open Network Stream then enter the IP or hostname of your Maivin using the following format (note the x are placeholders for your Maivin serial number).

tcp://verdin-imx8mp-xxxxxxxx:9000

Environment

The maivin/gstreamer container provides a few key environment variables which can be overridden to configure the stream.

• WIDTH
  • Controls the width of the camera capture, defaults to 1920.
• HEIGHT
  • Controls the height of the camera capture, defaults to 1080.
• PORT
  • Controls the listening port for the TCP server, defaults to 9000.
• MIRROR
  • Controls mirroring the camera capture, defaults to 1.
• FLIP
  • Controls flipping the camera capture, defaults to 1.

Note: MIRROR/FLIP default to 1 to provide expected orientation on the Maivin when setup with the heat sink facing upwards.
