# Subtitle Generator and API
Automatically generate subtitles from an input audio or video file using Open AI Whisper.
[](https://app.osaas.io/browse/eyevinn-auto-subtitles)
## Setup
### Requirements
The following environment variables can be set:
```text
OPENAI_API_KEY=
AWS_REGION= (optional can also be provided in payload)
AWS_ACCESS_KEY_ID= (optional, only needed when uploading to S3)
AWS_SECRET_ACCESS_KEY= (optional, only needed when uploading to S3)
```
Using an `.env` file is supported. Just rename `.env.example` to `.env` and insert your values.
### FFmpeg
FFmpeg is required to convert the input file/url to a format that Open AI Whisper can process. You can download it from [here](https://www.ffmpeg.org/download.html).
## Installation / Usage
Starting the service is as simple as running:
```bash
npm install
npm start
```
A docker image and docker-compose are also available:
```bash
docker-compose up --build -d
```
The transcribe service is now up and running and available on port `8000`.
### Endpoints
Available endpoints are:
| Endpoint | Method | Description |
| ---------------- | ------ | --------------------------------------------------- |
| `/` | `GET` | Heartbeat endpoint of service |
| `/transcribe` | `POST` | Create a new transcribe job. Provide url in body |
| `/transcribe/s3` | `POST` | Create a new transcribe job and upload result to s3 |
## Example requests
To start a new transcribe job send a `POST` request to the `/transcribe` endpoint with :
```jsonc
{
"url": "https://example.net/vod-audio_en=128000.aac"
"language": "en" // ISO 639-1 language code (https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) (optional)
"format": "vtt" // Supported formats: json, text, srt, verbose_json, or vtt (optional)
}
```
The response will look like this where result is the `WEBVTT` file as a string:
```json
{
"workerId": "BFabbcCi3IYuWOj6LfsgK",
"result": "WEBVTT\n\n00:00:00.000 --> 00:00:04.180\nor into transcoding I mean, I could probably add just the keyframe in the start and just\n\n00:00:04.180 --> 00:00:06.920\nskip I-frames and the rest of that.\n\n"
}
```
Formatted output:
```text
WEBVTT
00:00:00.000 --> 00:00:01.940
So into transcoding, I mean, I could
00:00:01.940 --> 00:00:03.700
probably add just a keyframe in the start
00:00:03.700 --> 00:00:06.700
and then just skip iFrames in the rest of the scenes.
```
