A script to turn Kodi with TVHeadend into a fully automated DVR
Turn your system into a fully automated TV recorder. It’s supposed to just work without further interaction with the end users (wife and kids). In fact they should not even notice anything is happening in the background. The system should just silently do it’s task, record all the favorite series and movies, remove all the advertising junk, convert everything to a decently compressed format and cleanly add every recording to the movie or series library.
For each of these tasks there’s good open source software available. But it is not just a simple download and run. Most needs to be compiled from source and the documentation is incomplete and scattered around the web. Nothing for a beginner at least. Also you have to manually run it on each recorded video. That’s very inconvenient and absolutely not acceptable for a family box.
Follow the steps below to set up the necessary software and install a little script to do all the processing. When it’s done, you just choose what to record and let the system do all the work for you.
Requirements:
This tutorial is supposed to be for everybody who is interested in an automated DVR. Even if you are an absolute beginner you should be able to succeed. No linux or programming skills whatsoever required!
All you need is:
- A Raspberry Pi (2 or 3 recommended, but even the first models should work). Everything except for the hardware encoding should also work on any other device including the Vero, but I can’t test this.
- Sufficient storage attached, either via USB or network.
- OSMC installed and set up.
- TVHeadend server installed from the OSMC App Store. You need to have everything set up to stream and record TV. There are plenty of good articles on that if you haven’t see here.
- Crontab from the OSMC App Store – if you want to run the CPU heavy commercial detection and transcoding on an overnight schedule (OPTIONAL).
- Ca. 2h of leisure time. Don’t be scared, most of the time is compiling so you can do other things in between.
Let’s start:
If you are not interested in one certain feature of my script you can just skip the corresponding steps. All optional components are marked so. Otherwise follow the instructions closely. For the impatient you can simply copy everything from the blue boxes to the command line.

tar xjvf ffmpeg-snapshot.tar.bz2
cd ffmpeg
export LDFLAGS="-L/opt/vc/lib -L/opt/vc/lib/pkgconfig -L/opt/vc/lib/plugins"
export CPPFLAGS='-I/opt/vc/include'

make -j4
make install
make distclean
cd $HOME
rm -R --interactive=never $HOME/sources/ffmpeg $HOME/ffmpeg_build
hash -r
Install Comskip (OPTIONAL)
(scans a video and marks commercial breaks)
# 7) Install dependencies:
cd $HOME/sources
sudo apt-get install autoconf automake git libargtable2-dev libtool
git clone git://github.com/erikkaashoek/Comskip
cd Comskip
./autogen.sh
./configure
make -j4
sudo make install
cd $HOME
rm -R --interactive=never $HOME/sources/Comskip
Install Filebot (OPTIONAL)
(renames video files to meet the Kodi standards and move files to your library folder)
8) Go to http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html and download the Java SDK „Linux ARM 32 Hard Float ABI“ (YES, ARM 32 even if you are on an RPi 3!) Take note of the Version no. which you’ll need later. In this example it is 8u131 Copy it somewhere to your Pi’s home folder (using Samba, FTP, it doesn’t matter). In the following I assume you placed it under ~/sources/jdk
cd $HOME/sources/jdk
tar -zxf jdk-8u131-linux-arm32-vfp-hflt.tar.gz
sudo mkdir /opt/jre
# 9) We are only interested in the runtime environment JRE, so we're only installing this and dump the rest. Note that the directory contains the version no. You have to adjust this with the one you wrote down.
sudo mv $HOME/sources/jdk/jdk1.8.0_131/jre /opt
sudo update-alternatives --install /usr/bin/java java /opt/jre/bin/java 100
rm -R --interactive=never $HOME/sources/jdk
# 10) Download Filebot
mkdir $HOME/sources/filebot
cd $HOME/sources/filebot
wget https://downloads.sourceforge.net/project/filebot/filebot/FileBot_4.7.9/filebot_4.7.9_armhf.deb
sudo dpkg -i $HOME/sources/filebot/filebot_4.7.9_armhf.deb
cd $HOME
rm -R --interactive=never $HOME/sources/filebot
Install Autoedit
cd /opt
git clone git://github.com/IfThenERROR/autoedit
chmod +x /opt/autoedit/autoedit
sudo update-alternatives --install /usr/bin/autoedit autoedit /opt/autoedit/autoedit 100
cp /opt/autoedit/comskip.ini $HOME/
nano /opt/autoedit/settings.txt
Change the settings to your liking. Especially the outfolder and language need to be set.
Set Cron job (OPTIONAL)
- To run all the magic overnight we want to create a schedule. The following runs autoedit every night on 2am. Change the time as you like.
crontab -e
Paste in the last line
0 2 * * * bash -l -c autoedit
Hit Ctrl+o and Ctrl+x to save.
Check if everything works
- Now let’s test all the installed parts.
java -version
Should output Java(TM) SE Runtime Environment (build 1.8.0_xxx-xxx)
ffmpeg -encoders | grep omx
Should output V..... h264_omx OpenMAX IL H.264 video encoder (codec h264)
comskip
Should output ComSkip: missing option <file>
autoedit --help
Should output Usage: bash autoedit (options) …
Tadaaaaa! Everything is ready.
Configure TVHeadend:
Now let’s hook up autoedit in TVHeadend. Open a browser and go to the TVHeadend interface (http://your_RPi_IP:9981). Go to Configuration→Recording and in the (Default Profile). In the field for „Post-Processor Command“ enter:
/usr/bin/autoedit --input "%f" --title "%t" --comskip --transcode mpeg2_mmal h264_omx 2000k --rename --wait
–input : This is the file to process, %f makes TVHeadend deliver the full path.
–title : Use this for series title. If not set autoedit will try to read the title from the metadata if present.
–episode : Use this for episode name. If not set autoedit will try to read the episode from the description in the metadata.
–comskip : Marks commercials for automatic skipping using Comskip.
–transcode [decoder] [encoder] [bitrate]: Transcodes the video using ffmpeg. The sample above does de- and encoding in RPi’s hardware and hence is pretty fast but only medium quality. For SD videos it’s near 90 fps. Make sure you use the correct settings here.
–rename : Rename the file to a Kodi compatible format using filebot.
–wait : Do not start processing immediately, just queue the video.
Also create a seccond profile for movies as filebot can’t reliably distinguish between movies and series. All settings here are the same as above, but „Post-Processor Command“ is „Post-Processor Command“ enter:
/usr/bin/autoedit --input "%f" --title "%t" --comskip --transcode mpeg2_mmal h264_omx 2000k --rename --movie --wait
Known issues:
- Quite many TV networks suck big time in properly labeling their broadcasts. They add fancy additions to series’ titles, don’t use the correct fields in the metadata and generally mess things up a lot. I wrote the postscript as robust as possible, and tried to remove the most common junk. But still sometimes the tags are just too messed up. So it doesn’t hurt to check your recording folder and the postscript’s log some here and then. If you regularly have problems with a series you can edit the script. The corresponding code is somewhere around line 100.
- Your video directory in the settings.txt should not contain blank spaces as Comskip is officially not able to handle these. It seems to still work, but is not thoroughly tested.
- Also if Comskip is set to decode in hardware, the little Raspberry is to busy to play a video smoothly at the same time. So Either turn of hardware decoding in the comskip.ini, or set the script to run nightly with cron.
- The standard package in Debian Stretch does not contain the h.265 decoder. If you wish to process videos with this compression, you need to resort to building ffmpeg from source. In this case refer to the instructions for Debian Jessie.
- If your system crashed not all is lost. Again the script is designed to be robust. You can resume an interupted run by entering „autoedit --forcerun“. This will try to pick up where it left.
I adjusted the makefile in my fork of comskip. Please delete the complete folder and clone again. I hope the error is gone then.
