François Laignel 743e97738f net/aws/transcriber: add translation request src pads
This commit adds an optional transcript translation feature implemented as
request src Pads.

When requesting a src Pad, the user can specify the translation language code
using Pad properties 'language-code'.

The following properties are defined on the Element:

- 'transcribe-latency': formerly 'latency', defines the expected latency for
  the Transcribe webservice.
- 'translate-latency': defines the expected latency for the Translate
  webservice.
- 'transcript-lookahead': maximum transcript duration to send to translation
  when a transcript is hitting its deadline and no punctuation was found.

When the input and output languages are the same, only the 'transcribe-latency'
is used for the Pad. Otherwise, the resulting latency is the addition of
'transcribe-latency' and 'translate-latency'.

gst-plugin-aws

This is a GStreamer plugin to interact with Amazon Web Services. We currently have elements to interact with S3 and Transcribe.

AWS Credentials

AWS credentials are picked up using the mechanism described by AWS SDK. 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:

[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.
