                How to broadcast to Icecast2 by using ffmpeg (FLAC,Opus,Vorbis,AAC,MP3/Windows, Mac)
              
          
    FFMpeg to Icecast2 Streaming Samples

Examples usage of various codecs with FFMpeg.
Samples


flac.sh : An Icecast Source Client

for Windows (Cygwin is required)
and macOS (brew install ffmpeg)


another_examples.sh : Samples
FFMpeg can push to Icecast2 in various formats: Opus/Vorbis/AAC/MP3
