This is a follow-up to my previous post related the DebConf videoteam using a new software stack for the next conferences: http://acaia.ca/~tiago/posts/c3video-for-dc-take-1/.
Installing C3TT scripts
There's a video (in German) which gives an idea about how the C3TT works: https://www.youtube.com/watch?v=K-KHbAcTo9I
It basically gives the volunteers a web interface to cut and review the recordings, wich communicates with a set of scripts running in background which will automate some tasks.
"Installing" the set of scripts is just a matter of placing them in a common directory and installing some Perl dependencies, mostly which are already packaged for Debian.
First check it out from the svn repository (fun fact: the web interface is coded in php in a git repository, the scripts are mostly written in perl with a little of bash, in a subversion repository. Both the conference and media system is are in ruby :)
$ svn co https://subversion.fem.tu-ilmenau.de/repository/cccongress $ mkdir /opt/crs; mv cccongress/trunk/tools /opt/crs/
A few libraries required:
$ apt-get install libboolean-perl libmath-round-perl libdatetime-perl libwww-curl-perl libconfig-inifiles-perl libxml-simple-perl $ perl -MCPAN -e 'install XML::RPC::Fast'
In the web tracker create a project, go to all projects => workers and create a worker (I'll try to explain it later). Go edit the worker and we'll see the token and secret that should be used in the scripts to talk to the interface.
Create a file tracker-profile.sh with the follow lines (using our correct values):
export CRS_TRACKER=http://localhost/rpc export CRS_TOKEN=2q24M7LW4Rk31YNW4tWKv8koNvyM3V4s export CRS_SECRET=5j8SyCS35W2SBk2XIM4IWeDUqF9agG1x
We also need to build and install the fuse-vdv package from trunk/tools (if working with dv files, otherwise fuse-ts package).
Next step is run the scripts. Fortunatelly a nice UI has been done using screen with multiple tabs, which can be alternated using a <Ctrl+a> <number> combination.
cd /opt/crs/tools/tracker3.0 && /start-screenrc-dv.sh
We'll get the following:
In a next post I'll try to explain a bit of how the web system work together with the scripts and how to do a basic setup for a real conference. I hope to get there soon!
