推荐答案
您需要对文件进行转码. iOS设备本身不支持WMV文件格式或其中的视频编解码器. (例如:WMV2，WVC1，等.)
You'll need to transcode the files. iOS devices do not natively suport WMV file format or the video codecs within. (E.g.: WMV2, WVC1, et al.)
iLounge:《 iPod，Apple TV和iPhone视频格式的完整指南》 是确定要使用的容器和编解码器的重要信息来源.请仔细阅读.虽然iOS设备支持MPEG-4/h264视频，但它们不支持任何和所有编解码器选项.这意味着您可以编码有效的h264视频，该视频将在您的PC上播放，但无法在iOS设备上播放.
iLounge: The Complete Guide to iPod, Apple TV and iPhone Video Formats is a great source of information for working out what containers and codecs you should target. Read it carefully. While iOS devices support MPEG-4/h264 videos, they do not support any and all codec options. That means you could encode a valid h264 video, which will play on your PC, but won't play on an iOS device.
如果可以的话，我建议您使用原始资料重新编码. FFmpeg + x264 是实现此目的的出色开源工具，尽管它们需要一定程度的技术支持. VLC 是另一个可靠的选择.
I'd recommend re-encoding from the source material if you can. FFmpeg + x264 are great open source tools for accomplishing this, although they will require a degree of technical sophistication. VLC is another solid option.
