We are moving tickets from the Plumi tracker (trac.plumi.org) here, for historical reasons.
Plumi is a Free Software video-sharing web application based on Plone and produced by https://www.engagemedia.org in collaboration with https://unweb.me.
Plumi enables you to create your own sophisticated video-sharing site. It includes a beautiful adaptive skin using Diazo, server-side transcoding of most video formats, upload progress bar, thumbnail extraction, HTML5 video playback and embedding, subtitles using Amara, large file uploading via FTP, social media integration, threaded commenting and user feedback forms, customised user profiles and a range of other useful features.

As of December 2016 Plumi has been tested on the following Operating Systems: Debian Jessie, Ubuntu 16, CentOS 7. It can be installed on other systems as well as long as they contain python2.7 and the system dependencies are installed.
For a small/medium portal hosting videos you'd need at least 1 core, 1G RAM, and disk size depending to the size of original videos being uploaded, plus the ones being transcoded (so if you estimate that you'll have 50 videos uploaded, each one of 100MB, you would need at least 70G of disk space)
For bigger installations you would need more RAM and cores. The specs for criticalcommons.org and engagemedia.org, the two biggest plumi installations are:
- criticalcommons.org: containing thousands of videos. 8 cores, 16G RAM and 2T of disk space.
- engagemedia.org: almost 10k videos. 2T disk for videos, 8 cores, 13G RAM. The disk OS and plumi is on a SSD disk, while a normal scsi disk is mounted for the transcoded/original videos.
If plumi is installed in /home/plumi.app, then
- /home/plumi.app/transcoded is used for transcoded videos
- /home/plumi.app/var/blobstorage for storing the original video files
So after installation you can delete /home/plumi.app/transcoded and /home/plumi.app/var/blobstorage and make them links to a separate disk (so you can maintain it easier). Of course if you can spare the whole system to be on SSD disks, you don't have to keep the above dirs on a separate disk

We will get plumi from it's github repository and install through a virtualenv environment. We'll install plumi in /home/plumi.app
root@user:~# cd /home/ root@user:/home# git clone https://github.com/plumi/plumi.app/ root@user:/home# cd plumi.app root@user:/home/plumi.app# virtualenv --no-setuptools .
Add users zope and www-data to the system (if server has nginx or apache www-data will be there already):
root@user:/home# adduser zope root@user:/home# adduser www-data
Edit file site.cfg and change users, if necessary (ftp user, cache user, etc). We'll leave the default site.cfg settings, that allow us to start supervisord (a supervisor process that is responsible to start/stop/monitor all processes plumi needs in order to run) as root, and then chmod to simple system users. Plumi processes can run as different users, for security reasons, while the default settings require that a user zope exists in order to run uwsgi web server.
However, we need to change these two lines:
www-server-name = new.plumi.org www-videoserver-name = newvideos.plumi.org
into:
www-server-name = mgogoulos.plumi.org www-videoserver-name = videos-mgogoulos.plumi.org
to reflect our existing dns. We need 2 dns names for plumi and the transcode daemon although they exist on the same system.
If this is a testing installation and we don't have dns yet, we can let the default settings (new.plumi.org and newvideos.plumi.org) and set these dns on our local /etc/hosts:
www.xx.yyy.zzz new.plumi.org newvideos.plumi.org
where www.xx.yyy.zzz is your ip address. After the buildout finishes we'll open our browser on http://new.plumi.org and will see the plumi installation
Make sure you set the same dns entries on /etc/hosts on both plumi server and your local system, if you're going to use dns names that are not resolvable, otherwise plumi won't behave correctly
root@user:/home/plumi.app# ./bin/python bootstrap.py && ./bin/buildout -v
This takes some time, it downloads and installs (on our virtualenv) all necessary packages for plumi to run, then installs the software and creates a plumi portal (on top of Plone).
There are 3 ways we can use ffmpeg to transcode videos:
- Install ffmpeg via source. Make sure it gets installed with libvpx/libvorbis
- Install ffmpeg via system package. We will cover this case for the 3 operating systems mentioned
- Install ffmpeg through the plumi buildout. This is tuned to compile ffmpeg with required settings and install ffmpeg on plumi installation dir. However the buildout hasn't been tested on all the 3 operating systems. On Debian Jessie buildout completes well and ffmpeg can trancode webm profiles, but segfaults when compiling mp4 files (so this cannot be used on Debian Jessie)
We will cover the system package installation here:
ffmpeg can be found on Debian Backports. To enable edit /etc/apt/sources.list and append line:
deb http://ftp.debian.org/debian jessie-backports main
Now install ffmpeg:
apt-get update; apt-get install ffmpeg -y
ffmpeg is part of the packages of a default Ubuntu 16.04 distribution so use apt-get install to install
root@ubuntu:~# apt-get update; apt-get install ffmpeg -y
ffmpeg can be found on atrpms repo. Enable epel-release before we can install ffmpeg:
root@centos:~# yum -y install epel-release root@centos:~# rpm -Uvh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-8.noarch.rpm root@centos:~# rpm -ivh https://www.mirrorservice.org/sites/dl.atrpms.net/el7-x86_64/atrpms/stable/atrpms-repo-7-7.el7.x86_64.rpm
Now edit /etc/yum.repos.d/atrpms.repo and under [atrpms] change the baseurl and enabled from. Set:
baseurl=http://dl.atrpms.net/el$releasever-$basearch/atrpms/stable enabled=1
to:
baseurl=https://www.mirrorservice.org/sites/dl.atrpms.net/el$releasever-$basearch/atrpms/stable enabled=0
now you can install ffmpeg:
root@centos:~# yum -y install ffmpeg
With plumi buildout having finished and ffmpeg installed on our system, it's time to run supervisord:
root@user:/home/plumi.app# ./bin/supervisord
after a few seconds, check that everything is up and running:
root@user:/home/plumi.app# ./bin/supervisorctl status cache RUNNING pid 22650, uptime 0:21:29 nginx RUNNING pid 22651, uptime 0:21:29 ploneftp RUNNING pid 22649, uptime 0:21:29 transcodedaemon RUNNING pid 22612 uptime 0:21:29 uwsgi RUNNING pid 22646, uptime 0:21:29 worker RUNNING pid 22647, uptime 0:21:29 zeo RUNNING pid 22645, uptime 0:21:29
(in case something is not running, check logs on var/log and partrs/transcodedaemon)
We have noticed that the worker process does not start properly some times. If that's the case, edit file parts/worker/etc/zope.conf and on the zodb_db main section make sure the blob-dir is set as the full path on the filesystem (eg /home/plumi.app/var/blobstorage).
We are good! Let's open a browser to http://new.plumi.org and see Plumi
