Build Status

Amazon S3 Gst Plugin

A collection of GStreamer elements to interact with the Amazon Simple Storage Service (S3).

Getting started

Setting up dependencies

Following dependencies are required to build the project:

Building the project

$ meson build
$ cd build
$ ninja
$ sudo ninja install

After executing commands above, the plugin (libgsts3elements.so) should be installed in the default GStreamer's plugin path. It can also be found in the build directory, and used by specifying the plugin path:

$ GST_PLUGIN_PATH=src gst-inspect-1.0 s3sink

Elements

  • s3sink - streams the multimedia to a specified bucket.

AWS Credentials

By default all the elements use the default credentials provider chain, which means, that credentials are read from the following sources:

  1. Environment variables: AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
  2. AWS credentials file. Usually located at ~/.aws/credentials.
  3. For EC2 instance, IAM instance profile.

Some of the elements have credentials property of GstAWSCredentials type, which is a wrapper for an Aws::Auth::AWSCredentialsProvider class.

Defining GstAWSCredentials as a string

The GstAWSCredentials object can be deserialized from a string, which makes using the property in gst-launch command possible. The string must be specified in the following format

property1=value1[|property2=value2[|property3=value3[|...]]]

Currently the deserializer accepts following properties:

  • access-key-id, e.g. AKIAIOSFODNN7EXAMPLE
  • secret-access-key, e.g. wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
  • session-token
  • iam-role, e.g. arn:aws:iam::123456789012:role/s3access

All the properties are optional, however, be aware of the rules:

  • access-key-id cannot exist without secret-access-key (and vice versa)
  • if session-token specified, both access-key-id and secret-access-key must be present
  • if iam-role is specified, it will use default credentials provider to assume the role, unless access-key-id and secret-access-key are present - in that case, these credentials are used to assume the role.

Examples

  • Streaming camera capture to an S3 bucket:
$ gst-launch-1.0 -e v4l2src num-buffers=300 device=/dev/video0 ! x264enc ! matroskamux ! s3sink bucket=my-personal-videos key=recording.mkv
