Plumi

Set up debord.mayfirst.org server. Then tried to set up plumi. What I currently have done is install apache2 php5 mysql-server and walked through  this instruction set.

 http://en.flossmanuals.net/Plumi/Installation

I tried creating a zope user but it did not work.

  • created video.debord.mayfirst.org
  • Setup Steps
  • Created Virtual Environment 
    virtualenv -p /user/bin/python2.4 --no-site-packages src/pyvirt

This is a python virtual environment to use python2.4 rather than 2.5, it lives at src/pyvirt

  • Did plumi buildout 
    svn co https://svn.plone.org/svn/collective/plumi.buildout/trunk plumi3
cd plumi3
python2.4 bootstrap.py 
./bin/buildout

The plumi build is at web/src/pyvirt/plumi3

  • Started services 
    ./bin/instance fg
    • zope server

The zope server can be configured inside the development environment @ plumi3/parts/instance/zope.conf

  • apache httpd.conf

Made configuration changes here to rewrite the url from video.debord.mayfirst.org:8080/ussfvideo to video.debord.mayfirst.org. /etc/apache2/httpd.conf

Transcoding Problems

Looking into the twisted.log I find the following transcoding process results.

It looks as if the trancoding daemon is getting called, but cannot complete.

The first thing that needed to be changed to deal with transcoding was this page.  http://video.debord.mayfirst.org/portal_properties/plumi_properties

I set the following server properties:

trancodedaemon_address  http://localhost:8888
videoserver_address  http://video.debord.mayfirst.org
plonesite_address  http://video.debord.mayfirst.org

This resulted in a successful transcoding of the thumbnail, tested with the following command from the ../pyvirt/plumi3 directory.

./scripts/getThumb ~/test.mp4 ~/test.jpg

While this resulted in a successful thumbnail conversion, the subsequent attempt to transcode video failed.

Failure to transcode video

The ffmpeg package from the main debian repository failed to recognize the option -vpre which resulted in an aborted trancoding. In order to get ffmpeg working in lenny, I took the following steps from this how to  http://techsiteblog.com/ffmpeg-and-x264/

Steps for ffmpeg install

  1. Installed needed libraries 
    aptitude install build-essential subversion git-core checkinstall yasm
texi2html libfaac-dev libfaad-dev libmp3lame-dev libopencore-amrnb-dev
libopencore-amrwb-dev libsdl1.2-dev libx11-dev libxfixes-dev
libxvidcore4-dev zlib1g-dev libogg-dev
  2. Added x264 
    git clone git://git.videolan.org/x264.git
cd x264
./configure
make
checkinstall --pkgname=x264 --pkgversion "1:0.svn`date +%Y%m%d`" --backup=no --default
  3. Installed libtheora 
    wget http://downloads.xiph.org/releases/theora/libtheora-1.1.1.tar.gz
tar xzvf libtheora-1.1.1.tar.gz
cd libtheora-1.1.1
./configure
make
checkinstall --pkgname=libtheora --pkgversion "1.1.1" --backup=no --default
  4. Installed ffmpeg 
    svn checkout svn://svn.ffmpeg.org/ffmpeg/trunk ffmpeg
cd ffmpeg
./configure --enable-gpl --enable-version3 --enable-nonfree
--enable-pthreads --enable-libfaac --enable-libfaad
--enable-libmp3lame --enable-libtheora --enable-libx264
--enable-x11grab 
make 
checkinstall --pkgname=ffmpeg --pkgversion "4:0.5+svn`date +%Y%m%d`" --backup=no --default
    1. The initial make did not work, and I had to run: 
      aptitude purge libx264-dev
    2. And repeat the ffmpeg configuration.
  5. Installed qt-faststart

From the ffmpeg source directory 

make tools/qt-faststart

At this point, ffmpeg can transcode mp4 formats using the following command: 

./scripts/transcodeMp4 ~/test.mp4 ~/test2.mp4

However, still cannot transcode into ogg format due to the ffmpeg2theora package.

ffmpeg2theora on debian lenny

Looking [ here] to determine how to get ffmpeg2theora latest release working on lenny:

Used these steps to install ffmpeg2theora

  1. Installed scons 
    aptitude install scons
  2. downloaded ffmpeg2theora from [ here]
  3. extracted the file 
    tar xvf ffmpeg2theora-0.26.tar.bz2
  4. Following steps to install 
    cd ffmpeg2theora-0.26
./get_ffmpeg_svn.sh
scons install

Success!
