The exports/sabr-stream module provides the SabrStream class, which serves as a SABR client designed for downloading videos. This module is the primary entry point for interacting with SABR-based video streams within the googlevideo package.

import { SabrStream } from 'googlevideo/exports/sabr-stream';

To interact with UMP data, use the following classes:

• UmpReader: Used for parsing and reading UMP data.
• UmpWriter: Used for constructing and writing UMP data.
• CompositeBuffer: A utility for managing buffers, likely used in conjunction with the reader and writer to handle data streams.

To run the "Onesie" request example, build the library, navigate to the specific example directory, install dependencies, and run the main script.

# Build the library first
npm run build

# Run the onesie-request example
cd examples/onesie-request
npm install
npx tsx main.ts

You can install the googlevideo package using NPM, JSR/Deno, or directly from GitHub depending on your environment.

# NPM
npm install googlevideo

# JSR / Deno
npx jsr add @luanrt/googlevideo
deno add jsr:@luanrt/googlevideo

# GitHub
npm install LuanRT/googlevideo

To run the downloader example, you must first build the library. Then, navigate to the downloader directory, install dependencies, and execute the main script or the ffmpeg-enabled script.

# Build the library first
npm run build

# Run the standard downloader
cd examples/downloader
npm install
npx tsx main.ts

# Run the downloader with ffmpeg support
npx tsx ffmpeg-example.ts

This example demonstrates how to integrate Shaka Player with the SabrStreamingAdapter from the googlevideo library to play YouTube videos.

To run the local development environment, follow these steps:

1. Install dependencies using npm.
2. Start the development server using the dev script.
3. Access the application via the local URL provided by Vite (typically http://localhost:5173).

Note: This is a minimal implementation. For a production-ready version with a full UI, DRM support, recommendation systems, and playback persistence, refer to the Kira project.

npm install
npm run dev

To use the SabrStreamingAdapter, instantiate it with a SabrOptions object. A playerAdapter (implementing SabrPlayerAdapter) is a required property in the options object. You can also configure caching behavior via enableCaching, maxCacheSizeMB, and maxCacheAgeSeconds.

import { SabrStreamingAdapter } from './src/core/SabrStreamingAdapter.js';

const adapter = new SabrStreamingAdapter({
  playerAdapter: myPlayerAdapter, // Must implement SabrPlayerAdapter
  enableCaching: true,
  maxCacheSizeMB: 5,
  maxCacheAgeSeconds: 600
});
