使视频能够流式播放

1. 视频应为.mp4格式。


2. 所有视频都应使用Miro Video Converter进行转换。 Mac（或类似的转换器），使其兼容iPhone，iPad和Android设备。
   转换后的视频将在移动设备中播放。但是，只有在从服务器下载完整视频后才能播放视频。


3. 要制作视频流，必须将视频的元数据移动到视频的开头。为实现这一目标，我们必须使用名为Medadata移动设备的工具对视频进行编码。


4. 然后最终视频兼容流媒体并能够在所有移动设备中播放。
   然后视频必须通过FTP连接到所需的虚拟主机。例如demo.com/videos/test.mp4。


5. 然后可以在iPhone或Android应用程序中配置视频，并且可以进行流式传输。

1. Video should be of .mp4 format.
2. All videos should be converted using the Miro Video Converter in Mac (Or similar converters) and make it compatible to play in iPhone, iPad and Android devices. Converted videos will play in mobile devices. However, the video will play only after the full video is downloaded from the server.
3. To make the video streaming, the video's metadata has to be moved to the beginning of the video. To achieve this, we have to use a tool called Medadata mover to encode the video.
4. Then the final video is compatible of streaming and able to play in all mobile devices. Then the video have to be FTP'ed to the desired web hosting. for example demo.com/videos/test.mp4.
5. Then the video can be configured in iPhone or android app and can be streamed.
