From deec840c0d9bb017ffb167f3ebd3348bf095fe75 Mon Sep 17 00:00:00 2001 From: Clinton Ebadi Date: Sun, 23 Nov 2014 22:15:25 -0500 Subject: [PATCH 1/1] xbmc file upload / playlist insert example XBMC party mode is good for background music at parties, but sometimes guests want to listen to their music and not mine. After trying to get UPnP/DLNA and bluetooth streaming to work I gave up and threw together a trivial file upload + python script. Primitive, so far. It lets users upload a single file to a specified directory, replaygains it (if it is mp3/flac/vorbis at least), and then inserts it at a random position on the playlist. --- xbmc/upload.html | 18 +++++++++ xbmc/upload.py.cgi | 98 ++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 116 insertions(+) create mode 100644 xbmc/upload.html create mode 100755 xbmc/upload.py.cgi diff --git a/xbmc/upload.html b/xbmc/upload.html new file mode 100644 index 0000000..3f7eae0 --- /dev/null +++ b/xbmc/upload.html @@ -0,0 +1,18 @@ + + + + + + + + diff --git a/xbmc/upload.py.cgi b/xbmc/upload.py.cgi new file mode 100755 index 0000000..a5d8682 --- /dev/null +++ b/xbmc/upload.py.cgi @@ -0,0 +1,98 @@ +#!/usr/bin/python + +# Trivial xbmc file upload script for parties +# Copyright (c) 2014 Clinton Ebadi +# This program is free software: you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation, either version 3 of the License, or +# (at your option) any later version. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
