Comskip commercial skipping on plex

Plex doesn’t seem to install comskip on linux by default. Although it says it uses it, it’s not in the tarball so nothing actually happens. I guess it assumes you’ve figured it out on your own(?).

Install comskip:

Dependencies:

apt-get install -y autoconf libtool git build-essential libargtable2-dev libavformat-dev libsdl1.2-dev

sudo su –

git clone git://github.com/erikkaashoek/Comskip

cd Comskip

./autogen.sh

./configure

make

make install

Auto-skip *should* work now if you set it up in the DVR settings, existing recordings won’t have commercials skipped.

Manual commercial scans (i.e. go fix my existing recordings!):

cd to your recording

comskip –ini=/usr/lib/plexmediaserver/Resources/comskip.ini MyRecording.ts

and wait.

it makes the edl and txt files for Plex to skip commercials, but does not modify the original file in any way

Or, go hit your entire DVR directory recursively:

Save this as /usr/bin/findcommercials

#!/bin/bash

# Save default separator definitions

oIFS=$IFS

# define new line as a separator, filenames can have spaces

IFS=$’\n’;

# For each file (f) listed as duplicated by fdupes, recursively

for f in `find . |grep .ts`

do

# Log the files we are touching

echo “Scanning for commercials in $f” >> ~/log.txt

echo “Scanning for commercials in $f”

# Run comskip

comskip –ini=/usr/lib/plexmediaserver/Resources/comskip.ini “$f”

done

# restore default separator definitions

IFS=$oIFS

To cut it up and make a new commercial free file:

cd ~

git clone https://github.com/BrettSheleski/comchap.git

cd comchap

cp comchap /usr/local/bin/comchap

cp comcut /usr/local/bin/comcut

comcut [OPTIONS] inputfile [OUTPUTFILE]

comcut –comskip-ini=/usr/lib/plexmediaserver/Resources/comskip.ini MyRecording.ts

To compress those pigs of ts files:

HandBrakeCLI -i The\ Wolverine\ \(2013\).ts -o The\ Wolverine\ \(2013\).mp4

There’s also:

ffmpeg -i input.ts -vcodec libx264 -vpre medium -crf 25 -ab 160k output.mp4 

playing with the crf affects final file size

So, loop it through every ts file to catch up on commercial skipping, and compress the ts to mp4 (and heat up the room):

Save this as /usr/bin/findcommercialsandcompress

#!/bin/bash

# Save default separator definitions

oIFS=$IFS

# define new line as a separator, filenames can have spaces

IFS=$’\n’;

# For each file (f) listed as duplicated by fdupes, recursively

  for f in `find . |grep .ts`

    do

      # Log the files we are touching

      echo “This whole process will take a LONG time”

      echo “Scanning for commercials in $f” >> ~/log.txt

      echo “Scanning for commercials in $f”

      # Run comskip

      comskip –ini=/usr/lib/plexmediaserver/Resources/comskip.ini “$f”

      # Run comcut

      echo “Cutting out commercials in $f”

     comcut –comskip-ini=/usr/lib/plexmediaserver/Resources/comskip.ini “$f”

     # Compress them all, use the original filenames and make them .mp4

      HandBrakeCLI -i ${f} -o ${f%.ts}.mp4

# Remove the original ts, if youre feeling brave

rm -f ${f}

done

# restore default separator definitions

IFS=$oIFS

Then:

chmod +x /usr/bin/findcommercialsandcompress

You should be able to cd into the root of wherever you want to and run: findcommercialsandcompress

Commercial scanning is pretty quick, 800+fps on my 

0:48:17 – 86853 frames in 105.40 sec(824.03 fps), 1.00 sec(828.00 fps), 50%

Don’t know how to make Plex do this automatically on Linux yet, but it has to be close… Maybe a symlink?
