[Etoys] GStreamer testing

So I sent an inquiry to the OLPC developer's list, asking which media
formats were supported out-of-the box on the XO. No answer.
But I found this table on the interwebs:
Media format Required package(s)
WAV, AU gstreamer-plugins-good
WMA gstreamer-ffmpeg, gstreamer-plugins-ugly
H.263 gstreamer-ffmpeg, gstreamer-plugins-good
MPEG1/2 gstreamer-ffmpeg, gstreamer-plugins-ugly
MPEG4 gstreamer-ffmpeg, gstreamer-plugins-ugly
WMV gstreamer-ffmpeg, gstreamer-plugins-ugly
3GP/MP4 gstreamer-ffmpeg, gstreamer-plugins-good
AVI gstreamer-ffmpeg, gstreamer-plugins-good
ASF gstreamer-ffmpeg, gstreamer-plugins-ugly
MPEG2 gstreamer-ffmpeg, gstreamer-plugins-ugly
OLPC ships only the "base" and "good" plugins. That means only Ogg is
fully supported, with ogg-vorbis for audio (music), ogg-speex (for
speech) and ogg-theora for video. Also, WAV and AU should work.
If someone installs "ffmpeg" and the "ugly" plugins (ugly license-
wise), a lot more formats become available, including MP3, AC3, WMA
for audio, MPEG and WMV for video, and depending on the codecs used
also some kinds of MP4, AVI, or ASF.
To install these on an XO, first do
sudo rpm -ivh http://rpm.livna.org/livna-release-7.rpm
sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-livna
which will install an unofficial Fedora 7 yum repository, and then
sudo yum install gstreamer-plugins-ugly gstreamer-ffmpeg
(this page was helpful to find this out: http://www.mjmwired.net/resources/mjm-fedora-f7.html)
We should definitely test with the various ogg formats, but with some
of the additional ones, too, as this was one of the points to go with
GStreamer. We should try to drag-and-drop from the web activity
directly into Etoys (via the frame clipboard) or download media to the
Journal and drag to the clipboard from there, and also the "start
with" menu in the journal.
