# What Is This?

This is a collection of utilities for working with Google Video APIs, with a primary focus on UMP.

* [Video Streaming Protos](./protos/video_streaming/)

* [UMP (Parser)](./src/core/UMP.ts)

* [ServerAbrStream (SABR Client)](./src/core/ServerAbrStream.ts)

* [ChunkedDataBuffer (Buffer Manager)](./src/core/ChunkedDataBuffer.ts)

You can find usage examples [here](./examples/).

## Installation

```bash

npm install github:LuanRT/googlevideo

```

## Basic Usage

```typescript

import GoogleVideo, { PART, Protos } from 'googlevideo';

const streamingUrl = 'https://abcd--a.googlevideo.com/videoplayback?...';

const response = await fetch(streamingUrl, { method: 'POST' });

const arrayBuffer = await response.arrayBuffer();

const dataBuffer = new GoogleVideo.ChunkedDataBuffer();

dataBuffer.append(new Uint8Array(arrayBuffer));

const googUmp = new GoogleVideo.UMP(dataBuffer);

googUmp.parse((part) => {

  switch (part.type) {

    case PART.MEDIA_HEADER: {

      console.log('[MediaHeader]:', Protos.MediaHeader.decode(part.data.chunks[0]));

      break;

    }

    case PART.MEDIA: {

      const headerId = part.data.getUint8(0);

      const streamData = part.data.split(1).remainingBuffer;

      console.log('[Media]:', `Header ID: ${headerId}`, `length: ${streamData.getLength()}`);

      break;

    }

    case PART.MEDIA_END: {

      const headerId = part.data.getUint8(0);

      console.log('[MediaEnd]:', `Header ID: ${headerId}`);

      break;

    }

    default:

      console.log('Unhandled part:', part.type);

      break;

  }

});

```
