centos 7, firefox 52.2.0, html5, h264 not working.

Post by iwishitwouldwork » 2017/11/28 04:00:33

tested:
Centos 7
firefox 52.2.0 and 57.0
52.2.0 is the one from the centos distribution, 57.0 is the one I got when I
downloaded from mozilla's website tonight.
Two different machines, one my production machine and one a fresh install.

visit the site http://www.youtube.com/html5 . I get checkmarks by
htmlvideoelement
media source extensions
webm vp8
mse & webm vp9
but I do not get checkmarks by:
h.264
mse & h.264

What I see online is that I'm supposed use firefox and visit about:config
and set various flags to certain values. I'm supposed to set
media.fragmented*
various suffixes, to various values, but none of these
appear on my machine (either version of firefox). I also read that these
flags are obsolete/deprecated from firefox 44.0 on, so i guess that's why.

media.mp4.enabled true
media.mediasource.enabled true
media.mediasource.mp4.enabled true
media.mediasource.webm.audio.enabled true
media.mediasource.webm.enabled true

So those are what I have, but those aren't the ones I'm supposed to have,
unless what I'm reading online is obsolete.
I checked plugins (open menu --> add-ons --> plugins) and it claims
openh264 is automatically installed. and active.

Chrome, by the way, works--that is, the youtube site gives me six
checkmarks.

So, does anyone know of a modern answer to whether firefox on linux
can do html5 video? Are there some rpms I might be missing? Seems
like that couldn't be the issue given that chrome works. (I've driven
myself a little bit nuts on this, I guess.) Yeah, yeah, i could use chrome
but I like firefox and it seems like firefox ought to work.

Activate a repository that has it (nux, rpmfusion, ...) and then type:

Code: Select all

# yum install ffmpeg-libs 
You surely have heard about patents and legal stuff before, haven't you?

Yup, that fixed it.

The remark about patents and such.... Is that the reason firefox
is "broken"? I hadn't heard.

But anyway, many thanks. I appreciate it.
It looks like I have needed rpmfusion for a long time. Now I have
that, too.
