[英]How to add AVQueuePlayer in subview to show view
我制作了一个AVQueuePlayer并添加了一些视频项目。 当我运行app时,会播放视频的声音,但未显示视频。 我知道视频未显示的原因,这是因为我不知道如何在视图中添加AVQueuePlayer。 请帮我
NSString *firstVideoPath = [[NSBundle mainBundle]
pathForResource:@"3" ofType:@"m4v"];
NSString *secondVideoPath = [[NSBundle mainBundle]
pathForResource:@"2" ofType:@"m4v"];
NSString *thirdVideoPath = [[NSBundle mainBundle]
pathForResource:@"3" ofType:@"m4v"];
AVPlayerItem *firstVideoItem = [AVPlayerItem playerItemWithURL:
[NSURL fileURLWithPath:firstVideoPath]];
AVPlayerItem *secondVideoItem = [AVPlayerItem playerItemWithURL:
[NSURL fileURLWithPath:secondVideoPath]];
AVPlayerItem *thirdVideoItem = [AVPlayerItem playerItemWithURL:
[NSURL fileURLWithPath:thirdVideoPath]];
self.queuePlayer = [AVQueuePlayer queuePlayerWithItems:
[NSArray arrayWithObjects:firstVideoItem,
secondVideoItem,thirdVideoItem,nil]];
[self.playerView setPlayer:self.queuePlayer];
[self.queuePlayer play];
首先,掌握所有路径:
NSString *firstVideoPath = [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"m4v"];
NSString *secondVideoPath = [[NSBundle mainBundle] pathForResource:@"demo" ofType:@"mp4"];
NSString *thirdVideoPath = [[NSBundle mainBundle] pathForResource:@"3" ofType:@"m4v"];
AVPlayerItem *firstVideoItem = [AVPlayerItem playerItemWithURL:[NSURL fileURLWithPath:firstVideoPath]];
AVPlayerItem *secondVideoItem = [AVPlayerItem playerItemWithURL:[NSURL fileURLWithPath:secondVideoPath]];
AVPlayerItem *thirdVideoItem = [AVPlayerItem playerItemWithURL:[NSURL fileURLWithPath:thirdVideoPath]];
初始化AVQueuePlayer:
AVQueuePlayer *queuePlayer = [AVQueuePlayer queuePlayerWithItems:@[firstVideoItem, secondVideoItem,thirdVideoItem]];
最后使用图层将所有电影显示为播放列表。
AVPlayerLayer *layer = [AVPlayerLayer layer];
[layer setPlayer:queuePlayer];
[layer setFrame:CGRectMake(10, 10, 300, 200)];
[layer setBackgroundColor:[UIColor redColor].CGColor];
[layer setVideoGravity:AVLayerVideoGravityResizeAspectFill];
[self.view.layer addSublayer:layer];
[queuePlayer play];
不要忘记添加框架:
#import <QuartzCore/QuartzCore.h>
#import "AVFoundation/AVFoundation.h"
