Question

在我的项目中使用 MobileVLCKit 3.0.0 播放媒体。

所有类型的视频在iOS9和10上成功播放，但 iOS 11视频音频能够收听，但图片无法显示并显示黑屏。

提供以下日志：

提前感谢。

Answer 1

最后，得到了解决方案......

现在'MobileVLCKit-Unstable'版本已于9月20日更新为master，UIKit来自后台线程（iOS 11视频播放）问题。

解决方法1：

将pod 'MobileVLCKit-unstable', '3.0.0a38'添加到podfile并运行pod install

解决方案2：

从以下网址克隆了回购：http://code.videolan.org/videolan/VLCKit.git
打开终端，导航到根目录并执行./buildMobileVLCKit.sh -f（注意：可能需要1-2小时才能完成）
成功完成后，将在VLCKit / build /文件夹位置生成MobileVLCKit.framework。
只需将其拖到您的项目中即可。

Answer 2

您需要在版本“3.0.0a38”或更高版本中将MobileVLCKit更新为pod'MobileVLCKit-unstable'。这个问题已经解决了。没有办法让库的旧版本以任何方式工作，因为它从后台线程调用UIKit。
