Compile FFmpeg on Ubuntu

This basic guide supports Ubuntu Xenial Xerus 16.04 and will enable several external encoding and decoding libraries: libfaac (AAC encoder), libfdk-aac (AAC encoder), libmp3lame (MP3 encoder), libopencore-amr (AMR encoder/decoder), librtmp (for additional RTMP protocols), libtheora (Theora encoder), libvorbis (Vorbis encoder), libvpx (VP8 encoder/decoder), and libx264 (H.264 encoder). These are optional and may be omitted if desired. This guide will also install many filters (see the filter list in the [Filtering Guide][1].

Note: Copy and paste the whole code box for each step.

Preparation

What?

A one-liner that pulls an AAC stream, pipes it into ffmpeg which transcodes it to mp3, then pipes it into ezstream with your settings (in the xml file) which streams it your radio.

Dependencies

sudo apt-get install ficy ffmpeg ezstream

FFmpeg Tricks

Repeat/loop Input Video

The -loop option is specific to the image file demuxer and gif muxer, so it can't be used for typical video files, but you can use the concat demuxer.

Concat demuxer

Make a text file. Contents of an example text file to repeat 4 times.

$ cat list.txt
file 'input.mp4'
