IOS视频循环播放

一、AVPlayer监听播放结束，实现循环播放

1. 添加播放器播放结束监听

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(playerItemDidPlayToEndTime:)
                                             name:AVPlayerItemDidPlayToEndTimeNotification
                                           object:nil];

2. 在结束访法中seek视频到开始时间点

- (void)playerItemDidPlayToEndTime:(NSNotification *)notification {
    [self.player seekToTime:kCMTimeZero]
}

二、AVPlayerLooper循环播放

原生方法，可完全替代方法一

NSURL *url = nil;
AVPlayerItem *playerItem = [[AVPlayerItem alloc] initWithURL:url];
AVQueuePlayer *player = [AVQueuePlayer queuePlayerWithItems:@[playerItem]];
AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];
AVPlayerLooper *playerLooper = [AVPlayerLooper playerLooperWithPlayer:player templateItem:playerItem];
[player play];

三、MPMoviePlayerController实现循环播放

self.url = [NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:@"new" ofType:@"mp4"]];
self.player = [[MPMoviePlayerController alloc] initWithContentURL:self.url];
[self.view addSubview:self.player.view];
self.player.shouldAutoplay = YES;
self.player.repeatMode = MPMovieRepeatModeOne;
[self.player.view setFrame:self.view.bounds];
self.player.scalingMode = MPMovieScalingModeAspectFill;
[self.player play];

四、ijkplayer循环播放

使用ijkPlayerDemo中的IJKFFMoviePlayerController做测试，IJKFFMoviePlayerController本身没有循环播放代码，需要手动添加一下。

先在IJKFFMoviePlayerController中添加loop属性，为bool类型，然后在.m文件421行添加相关代码 ijkmp_set_loop

- (void)play
{
    if (!_mediaPlayer)
        return;

    [self setScreenOn:_keepScreenOnWhilePlaying];

    [self startHudTimer];
    if (self.loop) {
        ijkmp_set_loop(_mediaPlayer, INT_MAX);
    } else {
        ijkmp_set_loop(_mediaPlayer, 1);
    }
    
    ijkmp_start(_mediaPlayer);
}

使用方法

self.videoPlayer = [[IJKFFMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:path] withOptions:options];
self.videoPlayer.view.autoresizingMask = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
self.videoPlayer.view.frame = self.view.bounds;
self.videoPlayer.loop = YES;
self.videoPlayer.scalingMode = IJKMPMovieScalingModeAspectFill;
self.videoPlayer.shouldAutoplay = YES;
//        self.containView.autoresizesSubviews = YES;
[self.view addSubview:self.videoPlayer.view];
[self.videoPlayer prepareToPlay];
[self.videoPlayer play];
