Mathieu Duponchelle 640ce43fee awstranscriber: make use of new result stability AWS API option 
<https://aws.amazon.com/blogs/machine-learning/amazon-transcribe-now-supports-partial-results-stabilization-for-streaming-audio/>

Amazon seem to have realized the previous iteration of their API
made it difficult to identify items from one result to the next,
which made the element much more complicated than it should have
been. With that new "stability" option, we can enqueue items as
soon as they stabilize, and simply rely on the current index in
the transcript to output them exactly once.

This also means the "use_partial_results" is now useless, as there
will be no difference in accuracy between a non-partial result and
and of its stable items that might have been pushed from previous
partial versions of the result.

The property is removed, instead a new option is exposed to let
users control how fast results should stabilize.

This greatly simplifies the code, and also improves the output as
punctuation doesn't need to be randomly discarded anymore.

gst-plugin-s3

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 that rusoto's ChainProvider uses. 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

awstranscriber

Transcribes audio to text.
