[Message part 1 (text/plain, inline)]

To play a video with totem, I have this problem:
 
An error occurred
The playback of this movie requires a MPEG-4 AAC decoder plugin which is not installed.

What package should be installed?

I'm not 100% sure, but I think you'd need the "bad" set of GStreamer
plugins — the package is called gst-plugins-bad. Totem is based on
GStreamer and gst-plugins-bad includes the faad2 AAC decoder.

Maybe we should add these plugins to our Totem package?

gst-libav should also be sufficient.  Also, it *might* be necessary to
install 'gstreamer' to the same profile that 'gst-*' is installed in, to
ensure that the environment variables are automatically set as needed.

I think it's important that plugins with patent-encumbered codecs, or
codecs with code quality issues, should remain *optional*, and not be
installed automatically.  It should be possible to install a modern
desktop environment in Guix that does not include these codecs.

What do you think?

      Thanks,
        Mark

What should I do now? Install this plugin from the source?

If you're OK with using patent-encumbered codex like MP4 simply:

 $ guix install gst-libav

if that doesn't fix your troubles:

 $ guix install gst-plugins-bad

(You won't need both.)

Kind regards,
