I had the same problem. Installing x264 did not help. However, checking ffmpeg I found it to be a 2x version. I installed the latest ffmpeg package from alienbob and the problem is resolved.

Since it just worked in Chromium, I was just too lazy to try and figure it out. Saw this thread and decided to check - now GIFs also work in FF.

Thanks to all!

I'd be really surprised if gifs didn't work before (it's been a standard, well-supported format for decades), however, most gif sites actually provide you an mp4 file nowadays, basically a silent video. They do this since compression, quality, and file size are all drastically better (and the user almost never notices it... unless their system can't play the mp4).

The GIF would be there, not animated, until clicked. Then, after it was clicked, it disappeared and left a white screen where the GIF pic was. Not even a square, just plain white.

That worked for me too.

I had ffmpeg v3.0 but it was not AlienBob's.

I grabbed the 14.1 version from

http://www.slackware.com/~alien/slac.../ffmpeg/pkg64/

The video now plays and the following shows all 6 decoders available.

I'll try my 14.2 box tonight.

Thanks much everyone!

that worked because Alien Bob's ffmpeg has x264 (or whatever other codec the video uses) built-in statically.

if you want to use SBo's ffmpeg, like 55020 told you above, you have to build it against x264 (or whatever other codec the video uses), in its README it's explained how to do it.

Here is the contents of my sbopkg .sqf file that I used for installing ffmpeg. I left out bluray stuff and probably some other items someone will find essential, and ignore version info since this was redone from earlier efforts. Since I know very little about multimedia, this is mostly a guess.

AlienBob's 14.2 ffmpeg fixed the Firefox youtube playback on Slackware 14.2 also. Fantastic.

Same problem here with videos. After reading this thread, i installed x264 and then ffmpeg from slackbuilds (for 14.2).
And now, every video i try, plays flawlessly. Thank you all.
A note: i built ffmpeg with the default options in slackbuild, that means x264 set to no.

Makes sense.. as Bassmadrigal mentioned it's an encoder as is x265.

My problem wasn't with Firefox - I've never had issues on that front, but rather with playing x265 encoded video on any player (which worked a month ago but for some reason stopped during one of my updates - not sure when).

I downloaded ffmpeg from slackbuilds because it includes libavcodec which may have been what actually solved the Firefox issues too, but that's just a guess.

Oh, boy, kudos to all of you guys for solving this!!!

I've been having same issues with Firefox not playing youtube videos with Flash since early October last year. Took me this long to find this solution.

Thanks again!!!!
