rmp-segment

rmp-segment is an open-source node.js HLS segmenter. It is built as a portable command line tool with ease of use in mind.

It follows the HTTP Live Streaming IETF sepcification. It uses FFmpeg for MPEG-2 TS segmenting.

rmp-segment is an open-source project released under GPL version 3. For business users we can provide a support and LGPL v3 licensing plan.

Supported features

• on-demand video segmenting (output to MPEG-2 TS container)
• adaptive bitrate streaming
• AES-128 encryption
• multiple audio
• audio-only (output to AAC container)

Currently unsupported features

Contributions are welcome!

Requirements

rmp-segment is developed with ES6 and makes uses of new ES6 features like Promise.

• Node.js version 4.4+
• OS Linux 64-bits
• Debian 8+
• Ubuntu 14+
• Fedora 24+
• OS Windows 64-bits:
• Windows 8.1+ (PowerShell)

These are the OS we tested rmp-segment on. 32-bits OS are not supported.

Install

npm install -g rmp-segment

Usage

rmp-segment -i input/bbb -o output/bbb

The segmenter will locate all valid input files (.mp4|.m4a|.m4v) in input/bbb and write the .ts chunks and .m3u8 playlists at output/bbb

For developers

git clone https://github.com/radiantmediaplayer/rmp-segment.git
cd rmp-segment
npm install

Install grunt-cli, jshint and jasmine globally (if you do not already have them):

npm install -g grunt-cli
npm install -g jshint
npm install -g jasmine

In working directory (where main.js is) run:

grunt

If it greenlights (jshint + jasmine tests are ok) you are good to go.
