# Serverless Subtitles

Serverless Subtitles is a demonstration project which allows you to prove the

usage of several AWS Products.

Original idea by Maxime THOMAS - [email protected]

Open Source Code under [Apache License](LICENSE)

## Pitch

You have a video but it's in english and you have difficulties to understand it.

Serverless Subtitles can handle a video input, extract the sound, transcript it

and generate different subtitle files for your video.

![Upload of the MP4 file](./doc/upload.gif)

When the file is processed, you can access to a preview of the video with

different generated languages.

![Play of the preview](./doc/play.gif)

Examples of the different VTT format files generated :

[EN](./doc/en.vtt) |

[FR](./doc/fr.vtt)

## TL;DR

This is working *only* in us-east-1 region so far.

    $ cd cloudformation;

    $ export USERNAME=

    $ ./create-all.sh

## AWS Services demonstrated

**Elastic Transcoder** :

Transcode is a service allowing you to transform videos.

We use it to extract the sound of a MP4 file to a MP3 file.

https://aws.amazon.com/en/elastictranscoder/

**Transcribe**

Transcribe is a service allowing you to transform speech to text.

We use it to get the transcript of the MP3 file.

https://aws.amazon.com/en/transcribe/

**Translate**

Translate is a service allowing you to translate text file in different

languages. We use it to translate subtitle files.

https://aws.amazon.com/en/translate/

## Solution Architecture

![Architecture of the solution](./doc/drawio.jpg)

## Set up

You must define a unique user id with only chars to setup this project.

We do so to avoid Bucket Name collision.

    $ cd cloudformation;

    $ export USERNAME=

    $ ./create-all.sh

The script will do the following :

* apply all cloudformation templates from the _cloudformation/templates_

directory

* set up the project :

    * uploading the lambdas functions;

    * creating mandatory keys in the S3 buckets;

    * generating a config file for the static website so JS client can directly

    access the resources with good arns.

* when everything is ready (about 2 min), you will get an url that should be

  like : http://subtitle.static.<username>.aws.com.s3-website-us-east-1.amazonaws.com/

## Set down

    $ cd cloudformation

    $ ./delete-all.sh
