# gst-plugin-s3
This is a [GStreamer](https://gstreamer.freedesktop.org/) plugin to interact
with [Amazon Web Services](https://aws.amazon.com/). We currently have elements
to interact with [S3](https://aws.amazon.com/s3) and
[Transcribe](https://aws.amazon.com/transcribe/).
## AWS Credentials
AWS credentials are picked up using the mechanism described by
[AWS SDK](https://docs.aws.amazon.com/sdk-for-rust/latest/dg/credentials.html).
At the moment, that is:
1. Environment variables: `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY`
2. AWS credentials file. Usually located at ~/.aws/credentials.
3. IAM instance profile. Will only work if running on an EC2 instance with an
instance profile/role.
An example credentials file might look like:
```ini
[default]
aws_access_key_id = ...
aws_secret_access_key = ...
```
## s3src
Reads from a given S3 (region, bucket, object, version?) tuple. The version may
be omitted, in which case the default behaviour of fetching the latest version
applies.
```
$ gst-launch-1.0 \
s3src uri=s3://ap-south-1/my-bucket/my-object-key/which-can-have-slashes?version=my-optional-version !
filesink name=my-object.out
```
## s3sink
Writes data to a specified S3 (region, bucket, object, version?) tuple. The
version may be omitted.
```
$ gst-launch-1.0 \
videotestsrc ! \
theoraenc ! \
oggmux ! \
s3sink uri=s3://us-west-1/example-bucket/my/file.ogv?version=my-optional-version
```
## s3hlssink
Writes a single variant HLS stream directly to a specified S3 (region, bucket,
path prefix) tuple. Takes the encoded audio and video stream as input, and uses
`hlssink3` if available, else `hlssink2`. HLS stream parameters such as
playlist length, segment duration, etc. can be tweaked by accesing the
underlying sink using the `hlssink` property.
## awstranscriber
Transcribes audio to text.
