Re: MPEG Support

["Jonathan C. Masters" <mastersj@periscope-systems.freeserve.co.uk>]

I have to disagree with you here. I believe that MPEG audio decoding/encoding
and MPEG video decoding/encoding optional devices such as /dev/mpad /dev/mpae
/dev/mpvd /dev/mpve would be emensely useful. It would save so much rewritten
code (libraries are never quite as good as they sound) and my programs would
instantaneously become much more enhanced. Besides, since MPEG decoding/encoding
cards are popular these days, you begin to see the speed required (so much so
that so many cards exist) so putting low level kernel routines into the kernel
would probably be the only way to achieve maximum software "emulation" of these
expensive cards.
