我看了很多,但到目前为止我还没有找到我的问题的直接答案。
所需的最低FFMpeg命令行输出和分段设置是什么,它将生成Apple App Store批准应用程序中播放的视频文件所需的所有必需HLS .m3u8和.ts文件组合的最小集合?
请注意,此处有较旧的Q& As,这是在FFMpeg为HLS添加原生细分之前编写的。因此,我正在寻找100%FFMpeg解决方案来输出Apple正在寻找的东西。我不关心这个答案的输入格式,因为FFMpeg读取了我们想要使用的大多数文件。
请注意,正确答案应考虑Apple寻找的总流量等的最大带宽要求设置。
我打赌那里有人已经得到了这个答案,甚至可能在一些代码中运行,但我希望看到它发布以节省我们其余的时间。
谢谢!

最小值是一个视频流和一个64k纯音频流,带有h.264和aac。也就是说,这就是我使用的,180p + 360p + 480p + 720p + 1080p + 64aac,只需将您需要的部件组合在一起。
我收到各种尺寸的视频,因此我的代码将所有内容打包或剪辑到16:9,如果您不需要,请将其删除。
此外,您需要生成指向其他主m3u8的主m3u。
[无论如何] - > h.264 + AAC
