<TD vAlign=top colSpan=2> one of the main
advantages of open standards, like mpeg-4 avc, is that
it leads to competition between various codec producers
as the consumer will always tend to use the product with
the best price/performance relationship.<BR><BR>
while prices are pretty well known for the consumer
there is one thing often lying in the dark: the actual
performance<BR><BR> while for the encoding side
quality comparisons exist, like the one from doom9,
decoders are often overlooked. of course, as every
decoder should output exactly the same picture and speed
also didnt really play a role as existing formats are
pretty easy to decode. <BR> but with a format,
like avc, which needs a lot of resources while decoding,
this might be different for a lot of people who dont own
top of the notch pcs.<BR><BR> so as avc is very
speed consuming and actually only one free avc decoder
is existing (libavcodec) it indeed makes sense to
compare the performance of existing decoders, before the
user decides what to spend his money on<BR><BR> in
this comparison i will compare the following
decoders:<BR>- ateme<BR>- elecard<BR>- libavcodec<BR>-
mainconcept<BR>- moonlight<BR>- nero<BR>-
videosoft<BR><BR> imho the quality of a decoder is
defined by four things:<BR>A) price<BR>B) supported
features of the format<BR>C) decoding speed<BR>D)
