Can't play mp4/h264 video on Fedora 26 (firefox)

Hello,

I spent hours trying to play mp4/h264 video on Fedora 26 but i keep having codec errors on Firefox and GNOME videos.

I followed instructions here https://fedoraproject.org/wiki/OpenH264 . And i've installed libmp4v2 from RPM fusion. But it didn't work.

Then i've desperately installed all gstreamer-plugins... but it still doesn't work.

However, i can play mp4 videos with vlc and chrome but my main goal is to use firefox without problem with video streaming...

If anybody had an idea, it'll be great ! :)

You need to add the RPMFusion to your repositories and install the ffmpeg package. I think the article you point out is kind of deprecated, the idea is that Firefox changed some things in regard to how it handles codecs and ffmpeg is compatible with it.

This test page will tell you which video format is supported.

It worked. Thank you very much Daniel01. I still trying to understand. I was testing on Lynda.com and http://www.html5videoplayer.net/html5... . I decided to reinstall my Fedora and install only ffmpeg. It work perfectly on my testing sites. But on the Youtube test page linked by villykruse, i've got H.264 and MSE & H.264 failed. Then i've reinstall packages describe here https://fedoraproject.org/wiki/OpenH264 and H.264 and MSE & H.264 is now supported on the Youtube test page... I feel like i'm missing something ^^'

Have you turned on "Play DRM content" option in Firefox settings?

If not, go to Preferences > Content > Tick on "Play DRM Content"

I remember having issue with that one time..
