icecast

https://www.icecast.org/ Icecast is a streaming media server
There are two major parts to most streaming media servers: the component providing the content (what we call source clients) and the component which is responsible for serving that content to listeners (this is the function of icecast).

✹https://echo.lurk.org:999/radioimplicancies.ogg - our icecast link

✹added the link in the audio player in the html (si12 website)

(another git dimension) useful to make changes directly on the platform without cloning and working from local (minor changes)

xpub special issues https://git.xpub.nl/XPUB/issue.xpub.nl 
xpub special issue 12 https://git.xpub.nl/XPUB/SI12-prototyping.git

sandbox

✹connect to the sandbox

 ssh hub.sandbox

✹place your file in the playlist

  scp file.mp3 hub.sandbox:/var/www/html/radio
      (your file)                    (complete path to the position of the playlist)

tmux

=terminal maximizer
✹connect to the shared sandbox terminal

(after ssh-ing the sandbox)
tmux -S /tmp/radio attach -t radio -r 
(-r means read only)

✹to detach from shared view

ctrl+b, release, then press d

add metadata to the ogg file

vorbiscomment -t "title=track_episodenumber_1” -t "file=filename.ogg" -t "authors=authorname” -t "episode=12.episodenumber” -w 
filename.ogg

✹or add them by creating a meta file

nano filename.meta
         (creates an empty meta file)

✹when inside nano you can add the metadata

authors=authorname episode=12.episodenumber description=description artist=video/imgpath
                           (the artist path can be a relative url that connects with the file in the git es. 12.4/filename.mp4)

✹then you can transfer the data from the .meta to the .ogg

vorbiscomment -c filename.meta -w filename.ogg

✹you can check id the data has been transfered correctly

vorbiscomment -l filename.ogg
