MP4 Plugin¶
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.
