CocoaPods Compatible Platform

Kakapos is a video add filter tool that supports network and local urls, as well as album videos.

Support macOS, iOS, tvOS and watchOS.


  • Set the conversion video storage sandbox link.
// Creating temp path to save the converted video
let outputURL: URL = {
    let documents = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
    let outputURL = documents.appendingPathComponent("condy_exporter_video.mp4")
    // Check if the file already exists then remove the previous file
    if FileManager.default.fileExists(atPath: outputURL.path) {
        do {
            try FileManager.default.removeItem(at: outputURL)
        } catch {
            //completionHandler(nil, error)
    return outputURL
  • Create the video exporter provider.
let provider = Exporter.Provider.init(with: ``URL Link``)


let provider = Exporter.Provider.init(with: ``AVAsset``)
  • Convert video and then add filters, convert buffer.
let filters: [C7FilterProtocol] = [
    C7Flip(horizontal: true, vertical: false),
    C7ColorConvert(with: .gray),
    C7SoulOut(soul: 0.3),
    MPSGaussianBlur(radius: 5),

let exporter = Exporter.init(provider: provider)

/// Export the video after add the filter.
/// - Parameters:
///   - options: Setup other parameters about export video.
///   - filtering: Filters work to filter pixel buffer.
///   - complete: The conversion is complete, including success or failure.
exporter.export(options: ``Exporter Options``, filtering: { buffer in
    let dest = BoxxIO(element: buffer, filters: filters)
    return try? dest.output()
}, complete: { res _ in
    // do somthing..

Swift Package Manager

Swift Package Manager is a tool for managing the distribution of Swift code. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies.

Xcode 11+ is required to build Kakapos using Swift Package Manager.

To integrate Harbeth into your Xcode project using Swift Package Manager, add it to the dependencies value of your Package.swift:

dependencies: [
    .package(url: "https://github.com/yangKJ/Kakapos.git", branch: "master"),


The general process is almost like this, the Demo is also written in great detail, you can check it out for yourself.🎷


Tip: If you find it helpful, please help me with a star. If you have any questions or needs, you can also issue.
