Bug#365516: gstreamer0.10-pitfdll: Doesn't handle "video/mpeg" that MPlayer can play

Nope.  If it's important, shouldn't something depend on it?

Anyway, I installed it and tried the same command line again:
"
johan at foo:/tmp$ LANG=C gst-launch-0.10 playbin uri=file:///tmp/johan.mpg
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /playbin0: Both autoaudiosink and alsasink
elements are missing.
Additional debug info:
gstplaybin.c(757): gen_audio_element (): /playbin0
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
FREEING pipeline ...
"

Now that I've installed gstreamer0.10-plugins-base:

It does now.

Good!  If *you* can view it without MPlayer, I'm confident I'll be
able to as well :-).
