Re: [gst-devel] Re: Helix Player virtual team meeting

Well I'm glad to hear that Real has improved the quality of its video
offerings recently.  It would perhaps have been more correct to say that
RealVideo has been historically substandard, as least as far as the
quality of video actually appearing in the RealVideo format, but it is
entirely possible that this will change in the future.

The other end of it, of course, is the pain associated with installing
the RealVideo codec in the first place.  On the Windows platform, of
course, Real is at an inherent disadvantage because of Windows Media
Player not shipping with a RealVideo codec.  Real should take steps to
make viewing their video less difficult for users.  For the vast
majority of users, installing RealOne is the only way they know how to
get access to viewing the video (if there's a DirectShow plugin, you
certainly can't get to it from the web site), and RealOne player by
default is extremely annoying.  Most users will never launch RealOne
player at all, instead relying on it to automatically launch,  But for
some reason, Real deemed it necessary to install incons for in it: quick
launch toolbar, start menu, programs menu, desktop, _and_ the system
tray.  In addition, it helpfully displays popup advertisements in the
corner of the screen at random intervals.  Why would any user subject
themselves to that?  And in turn, why would any web site offer video
content in the Real format if they must ask that users subject
themselves to RealOne in order to view it?  Even if its theoretically
possible to configure RealOne so that it's not so annoying, most users
will be unable to do so.

I realize of course that you're a codec engineer and so it's not your
fault, and of course rants about RealOne are hardly relevent on
desktop-devel, but it's something that frustrated me greatly when I
first installed RealOne some time ago.  It was like driving to the ice
cream shop only to discover that they were closed.
