Title:
Firefox 50 blocks Ubuntu 14.04 LTS's version of libavcodec
Status in firefox package in Ubuntu:
Confirmed
Status in libav package in Ubuntu:
Confirmed
Bug description:
Whenever it tries to play a video, Firefox 50 displays this message at the
top of every page:
"libavcodec may be vulnerable or is not supported, and should be updated to
play video"
https://dxr.mozilla.org/mozilla-central/source/browser/locales/en-
US/chrome/browser/browser.properties?q=%22libavcodec+may+be+vulnerable%22&redirect_type=single#742
Firefox refuses any libavcodec version prior to 54.35.1 (unless
media.libavcodec.allow-obsolete==true).
https://dxr.mozilla.org/mozilla-
central/source/dom/media/platforms/ffmpeg/FFmpegLibWrapper.cpp#60
Users should not be subjected to this warning, as it is vague (does not
instruct them how to fix it).
Ubuntu 14.04 LTS should ship with an updated version of libavcodec.
