| |
| This module provides streaming media server support for MP4 files. |
| User can send a HTTP request to the server with ``start`` argument |
| which is measured in seconds, and the server will respond with the |
| stream such that its start position corresponds to the requested time, |
| for example:: |
| |
| http://v.foo.com/dota2.mp4?start=290.12 |
| |
| This allows performing a random seeking at any time. We can use flash |
| player, vlc, mplayer, firefox or chrome to play the streaming media. |
| |
| This plugin can be used as a remap plugin. We can write this in remap.config:: |
| |
| map http://v.foo.com/ http://v.internal.com/ @plugin=mp4.so |

| Note |
| =================== |
| |
| This plugin requires that the ``moov`` box in the mp4 file should be ahead |
| of ``mdat`` box. It is not a good idea to cache a large mp4 file, many video |
| sites will cut a large video file into many small mp4 files, and each |
| small mp4 file will be less than 80M(bytes), it will be a reasonable choice. |
