Hello,
I am trying to get MP4/H.264 playback in Firefox to work on my CentOS
laptop (for vimeo).
I installed the gstreamer plugins as described here:
https://wiki.centos.org/TipsAndTricks/MultimediaOnCentOS7
(No, I did not install Flash, VLC and all the other stuff. I only want
HTML5 MP4 playback..)
I enabled the nux repos. I did install all available gstreamer
plugins, i.e. -good -bad -ugly -ffmpeg etc. No success.
Has anybody got mp4 playback working?
Here's a test page:
https://www.quirksmode.org/html5/tests/video.html
All movies on that page play without having taken any particular
precautions in Seamonkey (I dislike Firefox).
However, I have ffmpeg and mplayer installed (compiled from source
because there aren´t packages for those). I don´t know if any of them
are being used by Seamonkey.
yum list installed | grep gstream
gstreamer.x86_64 0.10.36-7.el7 @base
gstreamer-plugins-base.x86_64 0.10.36-10.el7 @base
gstreamer-tools.x86_64 0.10.36-7.el7 @base
gstreamer1.x86_64 1.10.4-2.el7 @base
gstreamer1-plugins-base.x86_64 1.10.4-1.el7 @base
Those must have been installed for dependencies; I didn´t install them
explicitly.
Installing ffmpeg-libs solved it for me. I suspect that FF links against
ffmpeg-libs or via gstreamer-ffmpeg or some such.
Thanks, Roman
