Firefox video issues

[nolddor]

Hi there,
Since a few weeks ago I've detected that Firefox ESR 52.9.0 (64-bit) cannot play some videos (using Debian testing).
For example, Facebook or Twitter videos doesn't play and also Spotify Webplayer doesn't work.

However, Flash videos & Youtube videos works like a charm.

When visiting https://www.youtube.com/html5, this is the output:


For example, If I tried to open this tweet:
https://twitter.com/officialjaden/statu ... 5944007680
A message 'We cannot play the video in this browser. Please try a different web browser.' appears


It seems that the problem is related with H.264 support...
Can someone help me a bit to figure out what is the problem, please?
Thanks in advance.

Your video link works for my Debian stable system and the HTML5 page shows six ticks.

Do you have libx264-148 installed?

I'm using Debian testing
I have got libx264-152 package installed, but not libx264-148 which it seems not available to be installed

Looks like it's not working then, have you searched for any existing bug reports? The reportbug package will list the current bugs.

EDIT: you could try pulling v60 of FF-ESR from sid, see if the new libraries work with that version.

EDIT2: https://release.debian.org/transitions/ ... -x264.html?

firefox-esr recommends libavcodec5*

Code: Select all

apt-cache depends libavcodec58 | grep libx26*
    Dépend: libx264-152
    Dépend: libx265-160

Firefox 52.X uses the gstreamer 1.0 framework, and you'll need gstreamer1.0-libav for h.264 playback.

Firefox 60+ uses libavcodecXX directly for this, and the Sid package pulls in one of them if your apt system installs Recommends as default, as Debian does.

I've seen several threads on Reddit of people complaining about the same thing. It's in the nature of Debian Testing, some functionality will be missing during package transitions.
Don't use Testing as a daily driver.

My Firefox version is 52.9.0 (64-bit) and If I type:

Code: Select all

dpkg -l | grep gstreamer1.0-libav

This is the output:
ii gstreamer1.0-libav:amd64 1.15.0.1+git20180723+db823502-1 amd64 libav plugin for GStreamer

So the package is already installed, and videos still doesn't work

ff esr 52 on my sid install plays the video

the problem is probably related to the 2 reds on the html5 check

my ff is all blue

the first link here may be useful

[nolddor]

And if you type the following:

Code: Select all

sudo locate libavcodec.so

What is your output?

Mine too.

I'm beginning to suspect a mixed system. nolddor, post your sources.list please.

Of course, it could be a problem with running Testing which does break; that's why they call it Testing. Or there could be a problem with a proprietary video software. Nvidia?

I have several browsers and was able to reproduce the problem with Qupzilla, version 2.2.5. Firefox 61.0.2, Slimjet 18.0.4.0 and Waterfox 56.2.2 handle your links easily.

Care to try an experiment? Download the Firefox Quantum app version tarball. Open it and run it in your user space. I bet that works.
