VLC Lua Plugin for Digital Imported Radio Stations

Question

Due to several reasons I currently need to play music using my client instead of mpd on my server. While I often listen to Digital Imported, I do not own an account there (and don't want one, escpecially not for each site), so I am stuck with their flashplayer, which let my old notebook make some noise by the fan.
First I created a parser in python, which sucks the needed information from their site(s), but then I stumbled across a(n) (old and partially broken) json-interface to their services. Since I already had VLC installed and was curious about doing something with Lua, I created a simple script for my purpose.
Disclaimer (mainly for the mods)
This is completly legal. All the script does is to grab the stream from the streamurl, using their on api/interface, which leads to bypass some dumb javascript checks, which try to force you to create an account for using an external player. You will also get their advertisements - same as using the flashplayer, so no illegal stuff in here.
Sites included
dI.fm
jazzradio.com
rockradio.com
sky.fm
Issues
Due to multihtreading in VLC, the lists must be sorted manually by clicking on the appropriate columnheader
Since the URLs point to .pls files, selecting an entry will open a new node instead to play the stream, so one needs to select twice
Because their interface is partially broken, some stations will only be reachable in .mp3 instead of .aac
The VLC service used to fetch json data (vlc.stream) will not follow HTTP headers, so the lists will be sometimes empty (sites return 206 instead of 200).
Installation
Create ~/.local/share/vlc/lua/sd and ~/.local/share/vlc/lua/sd/modules directories
Put the code below into the file ~/.local/share/vlc/lua/sd/di_vlc.lua
Link /usr/lib/vlc/lua/intf/modules/common.luac to ~/.local/share/vlc/lua/sd/modules/common.luac
Code
-- di_vlc.lua - VLC Service Discovery Plugin
-- Adds Digital Imported based Radiostations to the VLC Playlist Window
-- App (*nix): /usr/lib/vlc/
-- (win): C:\Program Files\VideoLAN\VLC\
-- Base (*nix): ~/.local/share/vlc/
-- (win): %appdata%\vlc\
-- Folder Structure:
-- $base/lua/sd/di_vlc.lua # This Script
-- $base/lua/sd/modules/common.luac # Found in $app/lua/intf/modules
lazy_loaded = false
json = nil
function lazy_load()
if lazy_loaded then return nil end
json = require "dkjson"
json["parse_url"] = function(url)
local string = ""
local line = ""
local stream = vlc.stream(url)
repeat
line = stream:readline()
string = string..line
until line ~= nil
return json.decode(string)
end
lazy_loaded = true
end
function descriptor()
return {title = "DI Radio Stations"}
end
function main()
lazy_load()
local stations = {["DI.FM"] = {"di.fm", "2"}, -- 2 = aac
["JazzRadio"] = {"jazzradio.com", "3"}, -- 3 = mp3 (aac pls = 404)
["RockRadio"] = {"rockradio.com", "2"}, -- 2 = aac
["Sky.FM"] = {"sky.fm", "3"}} -- 3 = mp3 (aac pls = 404)
for key, data in pairs(stations) do
local site = "http://www."..data[1]
local url = "http://listen."..data[1].."/public"..data[2]
local result = json.parse_url(url)
local node = vlc.sd.add_node({title = key})
if result then
for index, item in ipairs(result) do
node:add_subitem({title = item["name"],
path = item["playlist"],
description = item["description"],
genre = item["name"],
url = site,
publisher = "Digital Imported"})
end
end
end
end
Usage
Restart VLC and open the playlist. On the left side, below Internet, you should find a new entry called DI Radio Stations. Click it and have fun.
Comments are welcome.
