Usage

:warning: This library does not contain an API to crop or trim your video asset. You can find a possible implementation for this in the example pod, but the library only provides the UI.

Trimming

Create a TrimmerView instance (in interface builder or through code), and add it to your view hierarchy.

trimmerView.asset = asset
trimmerView.delegate = self

Access the startTime and endTime property to know where to trim your asset. You can use the TrimmerViewDelegate to link the trimmer with an AVPlayer and provide the end user with a preview. See the VideoTrimmerViewController inside the project to see an example.

You can also customize the trimmer view by changing its colors:

trimmerView.handleColor = UIColor.white
trimmerView.mainColor = UIColor.orange
trimmerView.positionBarColor = UIColor.white

Cropping

Create an instance of the VideoCropView and add it to your view hierarchy, then load your video into the crop view: videoCropView.asset = asset.

You can set the aspect ratio you want using the setAspectRatio method. Once you are satisfied with the portion of the asset you want to crop, call getImageCropFrame to retrieve the select frame. See the VideoCropperViewController in the example app for an actual example of how to crop the video for export.
