Serving in-file covers to MPD
It’s been quite a while that I’m using a MPD server on my raspberry + hifiberry  to play my digital music on my amps. It works very well, the sound is very good and I can control it with my phone, laptop, tablet etc… That is great.
What is less great is that MPD does not transmit covers to its clients (there is already an issue on MPD’s github  to let MPD natively find them).
What most clients do is asking you to setup a HTTP server above your music folder so that they can request the cover file with a query like:
GET /music/path/The%20Black%20Keys/Turn%20Blue/cover.jpg HTTP/1.1
This has 2 drawbacks:
- You need to leave an access to your music folder to the HTTP server. I’m not found of this. Some people worked around this  but meh…
- I don’t use cover files next to the songs. Whenever I rip a CD, I like to add the cover within the song files, so that it is nicely shown on my smartphone.
So I made a very simple python app to deal with this : mpdcoverserver. It has two options: a port and a music folder.
When the HTTP server receives :
GET /The%20Black%20Keys/Turn%20Blue/cover.jpg HTTP/1.1
it goes to
<music folder>/The Black Keys/Turn Blue/, takes the first song, extracts the cover from it and serves it.
