H264 is a codec used by your browser's html5 player (in this case). Correct me if im wrong!

Can you watch youtube's videos, using the HTML5 player, at 720p?
If you can: That's just a bug, H264 is enabled and you don't have to worry. :)

This H.264 codec is free software: https://github.com/cisco/openh264

Firefox downloads a binary of it that is free software too: http://www.openh264.org/BINARY_LICENSE.txt

That said, automatically downloading a blob from Cisco can be seen as a problem (is the binary really corresponding to the source code?). On my Abrowser, the codec is not used, i.e., media.gmp-gmpopenh264.provider.enabled is at false in about:config? I do not remember having toggled this option off, i.e., I believe quidam (Trisquel's main developer) must have set it this way.

No one needs OpenH264 built from source: they can use ffmpeg/libav/x264
instead. I think we shouldn't consider the Cisco binary free, when it's
mostly used for the binary-only patent license.

I haven't tested in Abrowser, but it looks like it came back in version 37 because the pref used to disable it changed (Iceweasel also disables it):
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=769716#83

EDIT: I checked the Debian package, and they have the following prefs
pref("media.gmp-manager.url.override", "data:text/plain,");
pref("media.gmp-gmpopenh264.enabled", false);

There is no "media.gmp-gmpopenh264.provider.enabled" entry in Iceweasel!

Iceweasel in each release's repositories is the ESR version (31, which doesn't have OpenH264). However, Debian also has an iceweasel package in experimental, which is the latest version.

I see. Yes I use the ESR one.

Hi,

I had never heard of this addon.
If I might ask, from what I know Firefox (Iceweasel, Icecat, Tor Browser, etc) comes with built-in support for WebM and OGG, correct? Without any additional codecs installed in your system, if you just install firefox, you can play those formats online, correct?
So, is it possible to have the same kind of support for H264 using this addon? Or does it depend on having some other software installed in your system?
Thanks

That's the point of the plugin. It's an attempt to work around patent restrictions.

It's really not useful for Trisquel, though, because the external software that plays h.264 is available on it.
