Vagrant+TMH: webm transcodes don't play in Firefox (upstream Ubuntu/avconv issue)
Closed, ResolvedPublic
Actions

Description

TimedMediaHandler uses avconv to transcode videos to various resolutions of .webm; however the version as shipped with Trusty (which the current MediaWiki-Vagrant uses) appears to be broken and produces files that don't play correctly in Firefox.

Upstream bug in Ubuntu tracker: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1323822

This is apparently fixed in avconv 9.14. If the fix isn't backported to Trusty, we may have to override the version of avconv we install.

What are the production transcode servers running?

Version: unspecified
Severity: normal
URL: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1323822

@brion or @Bawolff can you retest this? There is a comment on the upstream bug that seems to indicate this was fixed in July.
