Airplay songinfo [with short sample]

tatoosh

Do you plan to add the shairport -M Option to include airplay infos and cover?
Some infos:

To enable the output of metadata, the -M <directory name> flag must be set to instruct shairport where to save the output. This directory must exist. A fifo named now_playing will be created, and records will be written to it when tracks are changed. The end of a set of metadata is delimited by a zero-length line. Cover filenames are relative to the cover directory. Files are not deleted.

An example::

artist=Arcade Fire
title=City With No Children
album=The Suburbs
artwork=cover-e6450a45ab900815e831434f5ee0499c.jpg
genre=Rock
comment=

If not how can i help to implement this?

This solution worked:
[root@z1 shairport]# ls
cover-3372791b956da6821366a956d392b0ac.jpg cover-485dca5c932d9471d1f9941d7dc6e595.jpg cover-e0a25e508cd6bf1f0eca1eacb1b27242.jpg now_playing

but now_playing is empty ... i don't know why.

Got working by adding the -M <Folder> to the end of the configuration, first i added the arg at start.

Info (from my iPad Spotify premium) now looks:

[root@z1 shairport]# tail now_playing
artist=London Grammar
title=Strong
album=If You Wait
artwork=cover-6bb7f637c001a61f73e9c7beec787ce9.jpg
genre=

I ordered a 3.2" TFT for 10EUR in china, think it will arrive in Februar

Then i want to push the cover and infos to the TFT.

How to transfer this infos to the web interface?

I changed the metadata folder in the shairport.service like this:

--meta-dir=/var/www/shairport

And with this script i will get the cover in the webfolder shairport/cover.jpg. The sing infos are parsed to json to the same folder as now_playing.json.

Now i only have to trigger the filechange of now_playing to run my shell script and build a little PHP site to show the cover on the web ui.
Maybe someone can help me so i can use the normal web ui and don't have to build my own one

Here the getInfo.sh script:

#!/bin/bash

FOLDER=/var/www/shairport
pipe=$FOLDER/now_playing
datafile=$pipe.json

stringify() {
  a=${1%%=*}
  b=${1##*=}
  echo "\"$a\": \"$b\""
}

exec 4< $pipe
while read -ru 4 line ; do
  if [[ $line == artist* ]]; then
    echo '{' > $datafile
  elif [ -z "$line" ]; then
    echo '}' >> $datafile
    continue
  fi

  # jsonify the string
  data=$(stringify "$line")

  # for logging
#  echo $line

  # pretty print the JSON
  # comment is the last line of the output
  if [[ $line == comment* ]]; then
    echo "  $data" >> $datafile
  else
    echo "  $data," >> $datafile
  fi
done

exec 4<&-


rm $FOLDER/cover.jpg
FILE=$(ls -t $FOLDER/*.jpg | head -1)
cp -f $FILE $FOLDER/cover.jpg

echo Exiting

Here a fast php snippet to show the song info and cover after running the bash script:

http://runeaudio/shairport/index.php

<?php

$string = file_get_contents("now_playing.json");
$json_a=json_decode($string,true);

echo '<html><head><link rel="stylesheet" href="../css/runeui.1421133757.css"></head>

<body style="background: black"><div style="text-align: center;background-color: black;color: #34495E">';


foreach ($json_a as $key => $value){
  
  if ($key == "artwork") $cover = $value;
  else echo $key . ':' . $value;
  echo '<br>';
}

echo '<img src="' . $cover . '"/>';
echo '</div></body></html>';

?>

That shows you the info like this:
