Install ffms 2.19.02 and avxsynth onto Ubuntu 12.04

avxsynth is a linux friendly port of avisynth (the sadly dead video editor that you could script). While I know there are other options available, we have a goodly amount of avisynth scripts already that we would like to work with while we transition to a more permanent, better solution. In order to run avxsynth, it says we need FFMS2.

I used the following pages to put this together:

Compilation and Installation

Preperation

First, follow the instructions at http://interknighterrant.blogspot.com/2014/03/replace-libav-with-ffmpeg-in-lm16.html to compile ffmpeg.

mkdir ~/Downloads/avxsynth

cd ~/Downloads/avxsynth

Installation: FFMS2

git clone git://github.com/FFMS/ffms2.git

cd ./ffms2

./configure --enable-shared --with-pic

make

sudo checkinstall --pkgname=ffms2 --pkgversion="2.19.02-git" --backup=no --deldoc=yes --fstrans=no --default

cd ../

Installation: avxsynth

git clone git://github.com/avxsynth/avxsynth.git

cd avxsynth

autoreconf -fiv

./configure --enable-silent-rules --with-pic

make

sudo checkinstall --pkgname=avxsynth --pkgversion="4.0.01" --backup=no --deldoc=yes --fstrans=no --default

cd ../

Final Adjustments

Update libraries listings, just in case.

sudo ldconfig

Testing

cd ~/Videos

sudo cp "/usr/share/example-content/Ubuntu_Free_Culture_Showcase/How fast.ogg" ~/Videos/test.ogg

sudo chown YOURUSERNAME:YOURUSERNAME test.ogg

ffmsindex -t -1 test.ogg
Writing index... done... 100%

FFMS2 success! Now to try avxsynth

rm test.ogg.ffindex

printf "a=FFAudioSource(\"test.ogg\")\nv=FFVideoSource(\"test.ogg\")\nAudioDub(v,a)\nConvertToYV12()" >> test.avs

After a pretty short period of time (it will re-index), it plays fine! avxsynth success! Oddly enough, it won't stop playing after the movie has reached the end... but minor flaw in an otherwise successful process.

Un-install

To remove ffms and avxsynth:

sudo apt-get --purge remove ffms2 avxsynth

End Thoughts

The documentation for avxsynth is lacking in general. The most information that can be found is in that thread I linked to at Doom9's Forum. It has basic functionality of avisynth, a few plugins that have been ported, and a couple of additions. Stability wise, it seems like it has worked pretty stable (once you get it set up correctly). I like that I don't need to pipe the avs script in to ffmpeg or x264 anymore, it just works within the programs.
