[FFmpeg-user] Huffyuv huge files?

[Roger Pack]

Hello.  I noticed when attempting to use Huffyuv for screen capture,
that, even for a nonmoving image [screen in this case] it generates
*huge* files, even if the GOP is set high.  I would have expected it
to be a bit smarter in compression.
I see on this; http://lags.leetcode.net/codec.html the lagarith guys
mentioning that huffyuv has a "Predict Median" option.  I wonder if
that is an option that would really help out [somebody on a windows
computer test this out for me?]
I'm just really confused why Huffyuv is *so* huge when it's
recompressing the same frame over and over again.
Any other advice quite welcome.
Cheers!

UPDATE just saw this:
http://wiki.multimedia.cx/index.php?title=HuffYUV which implies that
every frame in HuffyUV is an I-frame.  This explains it, sorry for the
noise here, still posting it for followers, feedback also welcome.
