Bug#794193: epiphany-browser: missing recommends or depends on gstreamer1.0-libav

[Andres Salomon]

Package: epiphany-browser
Version: 3.14.1-1
Severity: normal

By default, epiphany-browser does not pull in gstreamer1.0-libav.  On a
normal gnome (or cinnamon) desktop, other packages such as totem,
cinnamon-desktop-environment, etc pull in gstreamer1.0-libav via
Recommends.  However, on an xfce4 desktop, there's nothing pulling in
gstreamer1.0-libav.

Epiphany uses gstreamer to play html5 media streams.  Going to
http://youtube.com/html5 shows me this with epiphany on a jessie system:
http://lunge.queued.net/~dilinger/html5.png .  However, 
the H.264 support that is claimed is actually a lie if
gstreamer1.0-libav isn't installed.  When playing H.264 videos (on
youtube and elsewhere), I get sound and previews, but no video.
Here's an example:  http://lunge.queued.net/~dilinger/cates.png
Installing gstreamer1.0-libav and restarting epiphany results in video
working properly.

So, epiphany-browser should probably have a Recommends or even a
hard Depends on gstreamer1.0-libav.  There are obviously some larger
issues at play here (like why there are no errors when webkit can't
play a video, and why it claims that the H264 codec is supported when it
actually isn't), but for Debian we can make it work easily enough by
including the proper package.
