I also have a too slow computer, but I was thinking about approaching it
from a different angle.
Why not use a very simple (computationally speaking) video codec for
live TV viewing. Sure it would take a lot of disk space, but disk space
is cheap. And when the machine is doing nothing (which is most of the
time) transcode into a more space efficient compression format for
archiving purposes. I've heard reports of P400s being able to do
realtime DVD encoding, so a full up MPEG2 at NTSC resolutions should be
achievable. And since the transcoding does not have to be real-time, it
can also perform high quality deinterlacing, noise reduction, commercial
Since it will be transcoding, the original encoding wants to be as high
a quality as possible, ideally lossless. What are computationally simple
video codecs with high video quality, and what IO requirements do they
have? And what's involved in adding a new codec and transcoding
capabilities to myth?
