Intro

This is a http streaming server within a single jar file. This is forked and optimized from Netty Example Code.

Key Feature

• The server supports and runs with non blocking i/o and zero copy.
• The server is written in Java and wrapped into a single jar, as a result it is very simple and compatible with any environment.
• It's lightweight. The jar file size is only 1.8MB!
• This server supports partial request.

Where to use

• This is optimized for media file streaming such as mp3 or mp4.

Requirement

• JDK 1.7+

Usage

First and foremost, please checkout the source code.

$ git clone https://github.com/lks21c/netty-http-streaming-server
$ cd netty-http-streaming-server/dist
# copy media files into dist
$ java -jar netty-server.jar

After launching the jar file, streaming server is run on 8283 port.

Then you can test media streaming is working via VLC player with url http://localhost:8283/sample.mp3.

You'll see log message below after playing the mp3 file via VLC.

Why I changed code from netty example.

The purpose of code change is that I removed "request chunked encoding" feature since it's unnecessary for media streaming server.(the server focuses on download, not upload)

And I also added code for Partial Request.
