CSTube (DEPRECATED)

CSTube is a lightweight, boilerplate-code-free port of the python library pytube for downloading YouTube Videos

Description

See pytube repo for API and usage. CSTube offers the same functionality as pytube but in the C# API using the .NET Framework. It comes with a sample WPF application able to download audio from multiple videos at once. (You need to enter each single URL though because I removed the Google API part for playlist fetching).

Features

• Support for Both Progressive & DASH Streams
• Complete async interface
• As for complete download interfaces inlcuding progress/complete callbacks, see CSTube_Win/YouTubeUtil.cs
• Caption Track Support
• Outputs Caption Tracks to .srt format (SubRip Subtitle)
• Ability to Capture Thumbnail URL.
• Extensively Documented Source Code

Compared to pytube:

• Adds dependency to NewtonSoft JSON (can be worked around but it is needed either way for Google API)
• No command line interface
• Complete WPF sample application

Installation

Clone repository. Now you can embed CSTube as a shared application in any other VS project or just copy out the source files and embed them directly. No fancy setup procedure, sorry:)

Getting started

See pytube readme - it is a similar interface. Also refer to the sample application!

Basically, create a new CSTube.Video by passing the URL into the constructor, this only initializes the object and video ID. To parse it and fetch all information:

CSTube.Video = new CSTube.Video(URL);
// Async:
await Video.FetchInformation();
// Sync:
Video.FetchInformation.Wait();

Then you can access all video information. Similar to pytube, to get the best-quality qudio stream:

CSTube.Stream bestAudio = video.streams.FilterStreams(onlyAudio: true).All()
	.OrderByDescending(s => Convert.ToInt32(s.getAttribute("bitrate"))).FirstOrDefault();
