Now that we have semi-functional end-to-end tests running upon commit to Gerrit (T103039), it would be helpful to have video recordings of MW-Selenium sessions, in case debugging/troubleshooting of failures is needed.
The headless gem provides this functionality but we haven't experimented with it recently.
Instructions from headless gem: https://github.com/leonid-shevtsov/headless#capturing-video
ffmpeg has been forked to a new project named libav. On the CI slaves, we include the puppet class mediawiki::packages::multimedia which uses ffmpeg on Precise but libav on Trusty:
class mediawiki::packages::multimedia { if os_version('ubuntu >= trusty') { $libav_package = 'libav-tools' } else { $libav_package = 'ffmpeg' } package { [ $libav_package, ]: ensure => present }
While setting up a Jessie slave I encountered the issue of not having ffmpeg. It is no more included in Debian (details at T103335). So definitely want to switch to libav and the avconv program.
