I am working on a task in which I have to trim the recorded video from particular start point to particular end point as entered or selected by user. How am I supposed to do that. As I used UIVideoEditorController before but I don't want to use the default view and I want to trim the video directly.
let FinalUrlTosave = NSURL(string: "\(newURL)")
exportSession!.outputURL=FinalUrlTosave
exportSession!.shouldOptimizeForNetworkUse = true
// exportSession.outputFileType = AVFileTypeQuickTimeMovie
exportSession!.outputFileType = AVFileTypeQuickTimeMovie;
let start:CMTime
let duration:CMTime
var st = starttime.doubleValue
var ed = endTime.doubleValue
start = CMTimeMakeWithSeconds(st, 600)
duration = CMTimeMakeWithSeconds(ed, 600)
// let timeRangeForCurrentSlice = CMTimeRangeMake(start, duration)
let range = CMTimeRangeMake(start, duration);
exportSession!.timeRange = range
exportSession!.exportAsynchronouslyWithCompletionHandler({
switch exportSession!.status{
case AVAssetExportSessionStatus.Failed:
print("failed \(exportSession!.error)")
case AVAssetExportSessionStatus.Cancelled:
print("cancelled \(exportSession!.error)")
default:
print("complete....complete")
// self.SaveVideoToPhotoLibrary(destinationURL1!)
}
})
I am trying to achieve my goal using this but not succeeding.

I found my solution using this method and it works like a charm....
func cropVideo(sourceURL1: NSURL, statTime:Float, endTime:Float)
{
let manager = NSFileManager.defaultManager()
guard let documentDirectory = try? manager.URLForDirectory(.DocumentDirectory, inDomain: .UserDomainMask, appropriateForURL: nil, create: true) else {return}
guard let mediaType = "mp4" as? String else {return}
guard let url = sourceURL1 as? NSURL else {return}
if mediaType == kUTTypeMovie as String || mediaType == "mp4" as String {
let asset = AVAsset(URL: url)
let length = Float(asset.duration.value) / Float(asset.duration.timescale)
print("video length: \(length) seconds")
let start = statTime
let end = endTime
var outputURL = documentDirectory.URLByAppendingPathComponent("output")
do {
try manager.createDirectoryAtURL(outputURL, withIntermediateDirectories: true, attributes: nil)
let name = Moment.newName()
outputURL = outputURL.URLByAppendingPathComponent("\(name).mp4")
}catch let error {
print(error)
}
//Remove existing file

guard let exportSession = AVAssetExportSession(asset: asset, presetName: AVAssetExportPresetHighestQuality) else {return}

exportSession.outputFileType = AVFileTypeMPEG4
let startTime = CMTime(seconds: Double(start ?? 0), preferredTimescale: 1000)
let endTime = CMTime(seconds: Double(end ?? length), preferredTimescale: 1000)
let timeRange = CMTimeRange(start: startTime, end: endTime)
exportSession.timeRange = timeRange
exportSession.exportAsynchronouslyWithCompletionHandler{

self.saveVideoTimeline(outputURL)
