Usage

⚠️ This library doesn’t provide any Trimming Implementations. It has just provided the UI with video frames. You’ll get trimming area (means trimming start time and trimming finish time) and then you can do anything with these informations.

Trimming

Create an instance (in interface builder or through code) of the and add it to your view hierarchy.ShortClipVideoTrimmerContentView

    shortClipTrimmerContentView.delegate = self // shortClipTrimmerContentView is an instance of ShortClipVideoTrimmerContentView
    shortClipTrimmerContentView.startOperation(asset: asset, maxTrimmingDuration: maxTrimmingDuration, numberOfFramesPerCycle: numberOfFramesPerCycle)

Here is type of AVAsset. You have to specify how much maximum trimming duration (which is ) you need and how many frames should be shown per cycle (which is ). Then create a AVPlayer or something releated to AVPlayer. provide a timer which transferes current time of running Video. For exampleassetmaxTrimmingDurationnumberOfFramesPerCycle

// videoPlayer is an instance of AVPlayer
videoPlayer.addPeriodicTimeObserver(forInterval: CMTime(seconds: 0.01, preferredTimescale: 600), queue: .main) {  _ in
    
    shortClipTrimmerContentView.updatePositionBarConstraint(cmTime: videoPlayer.currentTime())
}

you can also customize the by changing it’s color and width’s of subcomponents.ShortClipVideoTrimmerContentView

shortClipTrimmerContentView.updateHandlerWidth(width : 10.0)
shortClipTrimmerContentView.updateKnobWidth(width : 3.0)
shortClipTrimmerContentView.updatePositionBarWidth(width : 4.0)
shortClipTrimmerContentView.updateTrimmingAreaBorderWidth(width : 2.0)
shortClipTrimmerContentView.handlerColor(color : UIColor.blue)
shortClipTrimmerContentView.updateTrimmingAreaBorderColor(color : UIColor.blue)
shortClipTrimmerContentView.updateKnobColor(color : UIColor.white)
shortClipTrimmerContentView.updatePositionBarColor(color : UIColor.white)
shortClipTrimmerContentView.updateTrimmingOutsideBackgroundColor(color : UIColor.white)
shortClipTrimmerContentView.updateTrimmingOutsideMaskAlpha(alpha : 0.5)   
    

By conforming you’ll get the information about when trimming start and end position is changed. For better understanding please see the example project.ShortClipVideoTrimmerContentViewDelegate
