废话不多说，今天开发中遇到MPMoviePlayerViewController播放网络视频，没播放就自动dismiss的问题，Android端可以正常播放，但是IOS拍的视频上传到服务器端后可以正常播放，IOS模拟器测试又是好的，蛋疼，最后怀疑是视频编码的问题。看到MPMoviePlayerViewController文档中有这么一段描述：
Supported Formats
This class plays any movie or audio file supported in iOS. This includes both streamed content and fixed-length files. For movie files, this typically means files with the extensions .mov, .mp4, .mpv, and .3gp and using one of the following compression standards:
- H.264 Baseline Profile Level 3.0 video, up to 640 x 480 at 30 fps. (The Baseline profile does not support B frames.)
- MPEG-4 Part 2 video (Simple Profile)
If you use this class to play audio files, it displays a white screen with a QuickTime logo while the audio plays. For audio files, this class supports AAC-LC audio at up to 48 kHz, and MP3 (MPEG-1 Audio Layer 3) up to 48 kHz, stereo audio.
对比了下两个视频编码，左边的是IOS的右边的是Android的，H.264是视频编码，AAC和AMR是音频编码，想想估计是IOS这边不支持这种音频编码的格式，然后Android那边改成AAC的就好了。当然这里是我遇到这种问题的解决办法，可能还会有其他原因导致这种问题。
