Hi everyone Being on Linux Mint 17, I've noticed that Chromium stopped playing certain animated gifs a few weeks (probably after an upgrade of the browser). Switching to Firefox, I had the same problem, but I got at least a message: libavcodec may be vulnerable or is not supported, and should be updated to play video Following the instructions here solved my problem: http://superuser.com/a/1137409 However, Chromium still doesn't work. Maybe it's not linking to the libavcodec libraries, but including them in their build, using the outdated Mint 17 libraries.
