Transcoder

Transcoder the command line audio / video transcoder tool

Introduction

Transcoder is a FFmpeg powered command line transcoding tool. It allows you to convert audio and video files between many formats.

Installing

npm install transcoder -g

USING

Transcoder is used as a stand-alone application. Now that you have Transcoder installed you can convert files using any of the following methods:

Convert an .avi to an .mp4

transcoder /path/to/video.avi /path/to/video.mp4

The above command will execute Transcoder and convert the video.avi file to a video.mp4 file using the appropriate encoder setup.

Convert a .mp3 to an .ogg

transcoder /path/to/audio.mp3 /path/to/audio.ogg

This will create an ogg encoded version of the audio.mp3 file specified.

Convert a .wav to an .aiff

transcoder /path/to/audio.wav /path/to/audio.aiff

This will convert audio.wav to audio.aiff.
