ah yes - no scaling... I was not considering that option as a
reasonable one :-) at least not in my deployment context... (no
"full-screen, 1 stream only" type of thing but rather multiwindow,
drag-on-top-of-other-windows-with-video environment... but that was
probably a bit outside of the context of the original post - sorry :-)

I didn't say it wasn't fast enough - i said it was not as fast as Xv
(this may have changed though but I have my reservations)...

only if you need this sort of "fun" - in many cases it is not needed
so Xv would do the job more efficiently (in my humble opinion anyway
[420planar out of codec, into Xv which then coverts to
display-relevant format without any 3d geometry/blending/etc.] - but i
am not about to join a flame war).

It's just that instead of having these "edge" points in functionality spectrum:
[NO scaling, cropping out window manager's and desktop's decorations
on many monitors]
["super-duper" blingineering, eye-candy blending, 3d rotation and
overlay - stuff that is "nice" and may be "fun" but is rarely (albeit
sometimes) a real "productivity booster"];
- it is nice to see Xv as an efficient solution/alternative for
displaying video content in a generic (functionality-wise, not
"eye-candy"-wise) windowing environment (one can watch video, write
some notes, change the music-tune that is playing, etc - but once
again I am skewing away from the topic here so I shall stop :-)
