[英]IOS trim video with range slider
I am using range slider to trim running video.But I can't stop the video to the specific time.我正在使用范围滑块修剪正在运行的视频。但我无法将视频停止到特定时间。 Here is the following code, that i am using:这是我正在使用的以下代码:
- (void)videoRange:(SAVideoRangeSlider *)videoRange didChangeLeftPosition: (CGFloat)leftPosition rightPosition:(CGFloat)rightPosition
{
self.startTime = leftPosition;
self.stopTime = rightPosition;
[self.movieController stop];
MPMoviePlayerController *player = self.movieController;
[player stop];
[player setCurrentPlaybackTime:self.startTime];
[player setEndPlaybackTime:self.stopTime];
[player play];
}
setCurrentPlaybackTime is working, But "setEndPlaybackTime" is not working. setCurrentPlaybackTime 有效,但“setEndPlaybackTime”无效。 Please help me to progress my project work.请帮助我推进我的项目工作。 Thanks, Rohan谢谢,罗汉
I have faced this problem before and done a swift package for this我之前遇到过这个问题,并为此做了一个 swift 包
just in your xcode click只需在您的 xcode 中单击
file -> swift packages -> add package url文件 -> swift 包 -> 添加包 url
copy paste this url https://github.com/madadoux/DUTrimVideoView复制粘贴这个网址https://github.com/madadoux/DUTrimVideoView
it has a view model and you can make your own , pass it to the the initialiser它有一个视图模型,您可以创建自己的视图模型,并将其传递给初始化程序
example例子
class ViewController: UIViewController,VideoTrimViewDelegate {
func rangeSliderValueChanged(trimView: DUTrimVideoView, rangeSlider: DURangeSlider) {
}
func add() {
let url = URL(fileURLWithPath: Bundle.main.path(forResource: "video", ofType: "mp4")!)
let trimView = DUTrimVideoView(asset: AVAsset(url: url), frame: CGRect(x: 20, y: 200, width: self.view.frame.width-40, height: 100))
trimView.delegate = self
let rangeSlider = trimView.rangeSlider!
rangeSlider.leftThumbImage = UIImage(named: "trim-right")
rangeSlider.rightThumbImage = UIImage(named: "trim-left")
rangeSlider.thumbWidth = 30
rangeSlider.thumbHeight = 30
self.view.addSubview(trimView)
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
let btn = UIButton(type: .infoLight, primaryAction: UIAction(handler: { (a) in
self.view.subviews.filter({$0 is DUTrimVideoView }).first?.removeFromSuperview()
self.add()
}))
btn.frame = CGRect(origin: .zero, size: CGSize(width: 50, height: 50))
btn.center = self.view.center
self.view.addSubview(btn)
}
} }
hope that answered your question希望回答了你的问题
I can't remember where I got my range slider, but this one might be better https://github.com/muZZkat/NMRangeSlider我不记得我的范围滑块在哪里了,但这个可能更好https://github.com/muZZkat/NMRangeSlider
The one I had could give you a range of values easily.我拥有的那个可以轻松地为您提供一系列值。 Here is some code.这是一些代码。 min is for the first slider value and max is for the second slider value. min 用于第一个滑块值,max 用于第二个滑块值。
.h 。H
AVAssetExportSession *exportSession;
float max;
float min;
.m .m
- (void)trimVideo:(NSString *)outputURL assetObject:(AVAsset *)asset
{
@try
{
exportSession = [[AVAssetExportSession alloc]initWithAsset:asset presetName:AVAssetExportPresetHighestQuality];
exportSession.outputURL = [NSURL fileURLWithPath:outputURL];
exportSession.outputFileType = AVFileTypeQuickTimeMovie;
CMTime start = CMTimeMakeWithSeconds(min, 1);
CMTime duration = CMTimeMakeWithSeconds((max - min), 1);
CMTimeRange range = CMTimeRangeMake(start, duration);
exportSession.timeRange = range;
exportSession.outputFileType = AVFileTypeQuickTimeMovie;
[self checkExportSessionStatus:exportSession];
exportSession = nil;
}
@catch (NSException * e)
{
NSLog(@"Exception Name:%@ Reason:%@",[e name],[e reason]);
}
}
- (void)checkExportSessionStatus:(AVAssetExportSession *)exportSession
{
[exportSession exportAsynchronouslyWithCompletionHandler:^(void)
{
switch ([exportSession status])
{
case AVAssetExportSessionStatusCompleted:
{
[[[UIAlertView alloc] initWithTitle:@"Video Trimmed"
message:@"Your trimmed video has been sent to your finished videos."
delegate:nil
cancelButtonTitle:@"Ok"
otherButtonTitles:nil] show];
// dismiss progress bar or i use the SVProgress framework [SVProgressHUD dismiss];
// you can save it here
break;
}
case AVAssetExportSessionStatusFailed:
{
NSLog(@"Error in exporting");
[[[UIAlertView alloc] initWithTitle:@"Export fail"
message:nil
delegate:nil
cancelButtonTitle:@"Ok"
otherButtonTitles:nil] show];
}
break;
default:
{
break;
}
}
}];
}
I hope this helps a little.希望这会有帮助。 All you need to do is put the pieces together.您需要做的就是将各个部分放在一起。 You can get the SVProgress from here: https://github.com/TransitApp/SVProgressHUD您可以从这里获取 SVProgress: https : //github.com/TransitApp/SVProgressHUD
