Can't play Twitter's videos and GIFs with Firefox 46 for Fedora

Hello,

I' m running Firefox 46.0.1 in Fedora, however the bug I'm reporting has been there in 45 (and probably 44...). When I try to play a GIF in Twitter, I only have a black square instead (example : https://twitter.com/Anythingbatch/status/738079492418211840 ). If I pause the playback, I can see a still picture, but when I try to play it again, I get the black square again. More curiously, I have the same with Twitter's videos but I can hear the audio ! And if I click on the full screen button, I can watch the video in full screen mode without any problem.

I don't have this bug using GNOME Web or Google Chrome and it only happens with Twitter (no problem with FB or youtube).

Any idea ?

Not a Gif but a HTML5 video.

Check https://www.youtube.com/html5 to see what it says.

Ignore the outdated table on top of http://www.quirksmode.org/html5/tests/video.html and scroll down to H.264/MP4 video example.

If HTML5 videos are not working or properly then chances are you do not have the needed ffmpeg and Gstreamer packages installed for your Linux distro. Though Gstreamer may not be need in future versions of Firefox and just ffmpeg.

Can you otherwise play MP4 videos? https://pbs.twimg.com/tweet_video/Cj4r4LMXAAAy4kK.mp4

The list on the quirksmode website at the start of the page is a fixed image and doesn't represent your browser, but merely shows the state when this page originally got created years ago (you will notice Firefox 4.0b11). You need to scroll down the page to see if Firefox plays all offered media types.

Yes I can, and I can play both H264/Theora and WebM...

Ok. I tried to download the Firefox Beta (47.0) tarball directly from Mozilla website and it worked : I can play Twitter videos on it. However, I still can't with Firefox 46.0.1 (installed from the official Fedora repository). Could it be a bug in the package provided by Fedora ?
