This package allows to extract the direct video url or audio url for any YouTube video. This therefore allows to play YouTube videos in native UI components.
Disclaimer: YouTubeKit is currently still a work in progress, so it might not work in all regions.
The structurce of the code is strongly aligned with the pytube project (written in Python). This should make future breaking changes (by the YouTube API) easier to fix.
It requires iOS 13, watchOS 6, tvOS 13 or macOS 10.15, since it's relying on the Swift 5.5 Concurrency module. visionOS is also supported.
- Create a
YouTubeobject with thevideoURLorvideoIDof your video:
let video = YouTube(url: videoURL)or
let video = YouTube(videoID: videoID)- Extract all streams:
let streams = try await video.streamsThis will return an array of Stream objects.
- Filter for the stream you want by using a normal filter or with provided helper functions like:
let streamsAt1080 = streams.streams(withExactResolution: 1080)
let streamsBelow1080 = streams.filter(byResolution: $0 < 1080) // all streams with resolution lower than 1080p
let lowestResolution = streams.lowestResolutionStream()
let highestResolution = streams.highestResolutionStream()
let lowestAudioBitrate = streams.lowestAudioBitrateStream()
let highestAudioBitrate = streams.highestAudioBitrateStream()
let audioOnlyStreams = streams.filterAudioOnly() // all streams without video track
let videoOnlyStreams = streams.filterVideoOnly() // all streams without audio track
let combinedStreams = streams.filterVideoAndAudio() // all streams with both video and audio track- Retrieve metadata:
let metadata = try await video.metadataThis will return a YouTubeMetadata object.
To play a YouTube video in AVPlayer:
let stream = try await YouTube(videoID: "QdBZY2fkU-0").streams
.filterVideoAndAudio()
.filter { $0.isNativelyPlayable }
.highestResolutionStream()
let player = AVPlayer(url: stream!.url)
// -> Now present the player however you likeThe isNativelyPlayable parameter is used to filter only streams that are natively decodable on the current operating system and device.
To get the best m4a audio-only url for a given YouTube ID:
let stream = try await YouTube(videoID: "9bZkp7q19f0").streams
.filterAudioOnly()
.filter { $0.fileExtension == .m4a }
.highestAudioBitrateStream()
let streamURL = stream.urlTo get the video url of type mp4 with the highest available resolution for a given YouTube url:
let stream = try await YouTube(url: youtubeURL).streams
.filter { $0.includesVideoAndAudioTrack && $0.fileExtension == .mp4 }
.highestResolutionStream()
let streamURL = stream.url The isProgressive parameter is used to filter only streams that contain both video and audio.
To get the HLS url for a given YouTube ID of a livestream:
let hlsManifestUrl = try await YouTube(videoID: "21X5lGlDOfg").livestreams
.filter { $0.streamType == .hls }
.firstWith local YouTube extractors, there is the problem that YouTube might suddenly change their unofficial API, which can break your existing shipped app. It can take days or weeks for a user to update your app, rendering some features unusable for them in the meantime. To prevent this, YouTubeKit includes a feature that allows you to enable a remote fallback. As soon as local extraction fails, it switches to using a remote server running youtube-dl, that is updated frequently.
Simply specify the methods YouTubeKit should use in priority order. The rest of the API remains exactly the same — everything is handled by the library.
let streams = try await YouTube(videoID: "2lAe1cqCOXo", methods: [.local, .remote]).streamsYou can also set methods: [.remote] if you only want remote extraction.
Since streams are often bound to the device's location or IP address, we can't simply use youtube-dl on a remote server and send back the stream urls. Instead, the server makes all HTTP requests through the requesting device. When starting remote extraction, the device opens a WebSocket connection to the remote server. The server then sends multiple HTTP request packets to the device. The device executes these on behalf of the server and returns the full response. The server then processes and extracts the stream urls and sends them back to the device. This ensures the retrieved stream urls are playable on your device.
Currently, the default remote server is hosted by me. A way for you to host it yourself is coming soon.
