LightwaveRF Integration with XBMC

First, register your node to the LightwaveRF Wifi-Link

# echo -ne "666,\!F*p" | nc -u -w1 192.168.1.x 9760

(if may be useful to list on post 9761 to watch responses
# nc -ul 9761)

Then watch your WiFi-Link to confirm the new node.

Then you should be ready to start sending coommands
echo -ne "001,\!R1D2F1" | nc -u -w1 192.168.1.x 9760

I used XBMC Service Callbacks to hook into Play/Stop/Pause/Resume and to call these scripts to interact with the lightong (Lights off on Play/Resume, Lights On on Stop, and 40% dim on Pause).

(Cinema Experience will be a better way to do this in future, so you're not always turning on/off lights when watching regular/daytime TV and just for Movie Nights)

TBS Driver Interrupts

The TBS drivers needs to be enabled to use the PCI-MSI interrupts, as opposed to standard IRQ interrupts which it does by default.

After a few channel lockups, I noticed this in syslog:
Jan 17 04:08:08 wilfrodo kernel: [24621.425926] irq 18: nobody cared (try booting with the "irqpoll" option)
and lots of these:
Jan 17 18:14:47 wilfrodo tvheadend[881]: TS: TurboSight TBS 6985 DVBS/S2 frontend/ASTRA: 10,714,000 kHz Horizontal (No satconf)/More4 +1: MPEG2VIDEO @ #2367: Continuity counter error, 395 duplicate log lines suppressed
Jan 17 18:14:47 wilfrodo tvheadend[881]: TS: TurboSight TBS 6985 DVBS/S2 frontend/ASTRA: 10,714,000 kHz Horizontal (No satconf)/More4 +1: DVBSUB @ #2371: Continuity counter error, 6 duplicate log lines suppressed

So, the resolution is:
# cat /etc/modprobe.d/tbs.conf
options saa716x_tbs-dvb int_type=1

reboot, and hopefully you will see the card using the PCI-MSI interrupts now, and the issue should be fixed.

Installing comskip

Ok, so looking to install Comskip to remove the ads from programs I've recorded from TVHeadend.

Following instructions from here - http://forum.xbmc.org/showthread.php?tid=150084

Havent done any builds on this box so:
apt-get install build-essential

Looks like using latest ffmpeg is a good idea, details here:
https://launchpad.net/~jon-severinsson/+archive/ffmpeg

sudo add-apt-repository ppa:jon-severinsson/ffmpeg
apt-get update
apt-get install ffmpeg

Then grab
wget http://www.xilka.com/xilka/source/comskip-0.93f.tar.xz 
tar xvf comskip-0.93f.tar.xz
cd comskip-0.93f/
./configure --prefix=/usr

A few problems
checking for AVCODEC... no
configure: error: Package requirements (libavcodec >= 53.42) were not met:

No package 'libavcodec' found

so
apt-get install libavformat-dev

and try again
checking for ARGTABLE2... no
configure: error: Package requirements (argtable2 >= 9) were not met:

No package 'argtable2' found

once more
apt-get install libargtable2-dev

and try again:

checking that generated files are newer than configure... done
configure: creating ./config.status
config.status: creating Makefile
config.status: creating config.h
config.status: executing depfiles commands

Ready to build
make -j8
make install

If all went well we should be able to run comskip
Comskip 0.93f.000, made using avcodec

Now, we'll try to figure out how it works.
