New fangled to someone still running over a 9'600 connection!!! I could
certainly teach some of you lot lessons about bandwidth ;)))) What encoders
are you using under linux? Video encoding is sort of a hobby of mine at the
moment, I keep meaning to do some more linux video work but I never get
around to it.

Yep, certainly is a sight to behold - it'll be great when we get some of
these next-generation networks people keep talking about - not just more
bandwidth, but hard QoS guarantees & low latency also - that'll be when it
really starts to rock. We're about done as far as audio encoding is
concerned (i.e, we've hit the bit-rate floor, and got the most efficiency
we're able to get out of the stream, and these files aren't going to get any
smaller), video encoding is almost there (wavelet & fractal technology is
extremely interesting though, although extremely low quality in certain
circumstances). Streaming is certainly getting more and more important -
indeed, a lot of MPEG stuff (MPEG-7, MPEG-4,  MPEG-21, etc.) is dedicated
(at least in part) to streaming. Looks like QuickTime technology is going to
become defacto (I believe MPEG-4 & 7 use QT transport streams), which is a
shame given there's no QuickTime implementation on Linux at the moment.
Hopefully that'll change with the advent of OSX, unless Apple did something
silly and cocoa'd it... which *wouldn't* suprise me (that's how they got it
on Windows by all accounts).

Cheers,

Alex.
