GStreamer in Docker

Hello

1. 'gst-launch-1.0: command not found' error This usually caused by the GStreamer (with the Kinesis Video Streams Producer SDK element as a sink in a Docker container) not setup correctly.

After you have installed docker on your laptop( using MacOS) as example here:

1.1 Authenticate your Docker Client aws ecr get-login-password --region us-west-2 | docker login -u AWS --password-stdin https://546150905175.dkr.ecr.us-west-2.amazonaws.com

1.2 Download the Docker Image for macOS sudo docker pull 546150905175.dkr.ecr.us-west-2.amazonaws.com/kinesis-video-producer-sdk-cpp-amazon-linux:latest

1.3 Run the Docker Image on macOS sudo docker run -it --network="host" 546150905175.dkr.ecr.us-west-2.amazonaws.com/kinesis-video-producer-sdk-cpp-amazon-linux /bin/bash

Docker launches the container, and presents you with a command prompt for executing commands within the container. In the container, set the environment variables using the following command:

1.3.1 export LD_LIBRARY_PATH=/opt/awssdk/amazon-kinesis-video-streams-producer-sdk-cpp/kinesis-video-native-build/downloads/local/lib:$LD_LIBRARY_PATH 1.3.2 export PATH=/opt/awssdk/amazon-kinesis-video-streams-producer-sdk-cpp/kinesis-video-native-build/downloads/local/bin:$PATH 1.3.3 export GST_PLUGIN_PATH=/opt/awssdk/amazon-kinesis-video-streams-producer-sdk-cpp/kinesis-video-native-build/downloads/local/lib:$GST_PLUGIN_PATH

if above steps all successful, you should be prompted bash-4.2#(example only) able to run gst-launch-1.0 command

For example:

bash-4.2# gst-inspect-1.0 kvssink Factory Details: Rank primary + 10 (266) Long-name KVS Sink Klass Sink/Video/Network Description GStreamer AWS KVS plugin Author AWS KVS kinesis-video-support@amazon.com

Plugin Details: Name kvssink Description GStreamer AWS KVS plugin Filename /opt/amazon-kinesis-video-streams-producer-sdk-cpp/build/libgstkvssink.so Version 1.0 License Proprietary Source module kvssinkpackage Binary package GStreamer Origin URL http://gstreamer.net/

Regarding the second question: 2. To support video streaming from a PC webcam, do I need to install GStreamer plugins in Docker? If its yes can please share documentation for the GStreamer plugins setup in Docker

There are multiple options, you can either use the Producer libraries to build your own app. https://docs.aws.amazon.com/kinesisvideostreams/latest/dg/producer-sdk.html

Or you can use the GStreamer, The Kinesis Video Streams GStreamer plugin greatly simplifies the integration of your existing GStreamer media pipeline with Kinesis Video Streams. for this solution, yes, GStreamer plugins is necessary.
