iOS 11以下系统，是否支持hevc软解

[EalenLuo]

你好，我想问下，该项目iOS 11以下系统，是否支持对hevc进行软解呢？

[mayudong1]

支持的，在不支持硬解的系统上会自动使用软解来进行hevc的解码

使用cocopods集成到项目中，并按照wiki指导进行初始化：https://github.com/ksvc/KSYMediaPlayer_iOS/wiki/rapidIntegration

视频播放不出来，无画面，也没声音

可以问下这是为什么吗？

[mayudong1]

你可以直接clone下本仓库的代码，然后使用提供的demo来试试播放时什么效果
如果依然不能播放的话，应该就是不支持测试用的视频
另：测试用的视频是如何得到的，什么编码格式什么封装格式的呢

[EalenLuo]

是本地视频：h265编码，MP4封装，测试机为：iPhone6s iOS10.3.3 以下是测试视频的网盘地址： https://pan.baidu.com/s/1bXaUhK

[mayudong1]

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    NSString* path = [[NSBundle mainBundle]pathForResource:@"720P_30FPS" ofType:@"mp4"];
    NSURL* url = [NSURL URLWithString:path];
    player = [[KSYMoviePlayerController alloc]initWithContentURL:url];
    player.view.frame = self.view.bounds;
    [self.view addSubview:player.view];
    [player prepareToPlay];
}

以上代码测试是可以播放的（本地文件或者http方式都可以），你查一下是不是跟其他什么东西有冲突导致的吧

[EalenLuo]

好的，感谢，测试了是我代码问题。4K的播放会卡顿，是软解性能导致的吗？该项目软解h265，最大支持的分辨率是多大呢？
