Public bug reported: 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.
