Name

ts-mp4 - MP4 streaming media, implement as plugin of Apache TrafficServer

Status

This module is under active development and is production ready.

Description

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 or chrome to play the streaming media.

We can write this in remap.config:

map http://v.foo.com/ http://i.foo.com/ @plugin=/xx/libtsmp4.so

System Requirements

• linux/freebsd 64bits
• trafficserver

Build

step1: get ts-mp4

git clone https://github.com/portl4t/ts-mp4.git
cd ts-mp4/src

step2: build, requires linux/freebsd (64bits is recommended)

make

step3: modify remap.config and restart the trafficserver

Note

It is not a good idea to cache a large mp4 file, as we have to generate new meta data if start exists, and it will take a long time to accomplish. As far as I know, 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.
