XBMC remote control script for streams

synopsis

Xopr needed a quick way of 'zapping' through the streams of the 30C3 congress (also see no nerd left behind), so he wrote a remote control for his OpenELEC (XBMC, but it might work on RaspBMC as well) to open a predefined stream with one keypress from within a console:

CCC OPENELEC remote

1. Room one
2. Room two
4. Room G
6. Room six
x. exit
l. Language
q. Quality
Input(n:hq): _

code

It's a bash script and uses approximately 20x10 characters so you can place it next to your stream schedule

#!/bin/bash
# IP address of Raspbian/OPENELEC/XBMC box
IP=192.168.2.11
# Base stream url where [KEY] and [LANG] are replaced
STREAM=rtmp://rtmp.streaming.media.ccc.de:1935/stream/saal[KEY]_[LANG]_[QUALITY]
LANG=native
MENU_LANG=n
QUALITY=hq
MENU_QUALITY=hq
# ld hq hd
