我的视频没有音频流，但这没关系.
My video doesn't have an audio stream, but that shouldn't matter.
我的视频有什么问题，使其无法通过HTTP Live Streaming播放?
推荐答案
您的视频引人注目，级别4.2. iPhone 5 仅支持4.1以上的版本. iPhone 4 仅支持主配置文件级别3.1.另外23.1 MBps确实很高.最多3或4.
Your video is high profile, level 4.2. iPhone 5 only supports up level 4.1. iPhone 4 only supports up to main profile level 3.1. Also 23.1 Also MBps is really high. 3 or 4 is probably max.
