New Construction

1. New Construction
2. Drag the downloaded kxmovie and  FFmpeg-iOS into the project

3. Add the following dependent libraries:

- libz.tbd
- libbz2.tbd
- libiconv.tbd
- VideoToolBox.framework

4. Add running code

#import "ViewController.h"
#import "KxMovieViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
}
-(void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:animated];
    
    NSString *urlStr = @"https://vd3.bdstatic.com/mda-ja0k1pw5mvhn0rzh/mda-ja0k1pw5mvhn0rzh.mp4";
    NSMutableDictionary *param = [NSMutableDictionary dictionary];
    if ([urlStr.pathExtension isEqualToString:@""]) {
        param[KxMovieParameterMinBufferedDuration] = @(5.0);
    }
    
    
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
        param[KxMovieParameterDisableDeinterlacing] = @(YES);
    }
    KxMovieViewController *vc = [KxMovieViewController movieViewControllerWithContentPath:urlStr parameters:param];
    vc.modalPresentationStyle = UIModalPresentationFullScreen;
    [self presentViewController:vc animated:YES completion:nil];
}


@end

Compilation error solution

1. KxMovieDecoder cannot find UIImage

need ourselves#import <UIKit/UIKit.h>

2. A large number of error messages appear because the VideoToolBox has not been introduced

3. The solution to the error that libavformat/avformat.h cannot be found

Target -> Project -> Build Settings -> Library Search Path Copy the following content

1. libChange the suffix toinclude$(PROJECT_DIR)/HBFFmpeg/FFmpeg-iOS/include
2. Then add to Header Search Path
