Well, why is it so terrible? I mean, you can save up to 30Kbit/sec (or
more!) by going from 128Kbit mp3 to 88Kbit vorbis, and allocate 29
(maybe more!!) to the video stream itself.
True, seeking is a bit weird, but who cares?
On the other hand, index in avis are right on the end, so in order to
start playing an avi from a CD, your cdrom has to seek to the end, read
the index and then "rewind". Ogg does not have this. This means to me
that an avi in a CD takes about 5-6 seconds to start playing (while the
cdrom strives to read the last bytes of the 800MB cds) whereas ogg
starts immediately. Sometimes, i'm so pissed off that I use
$ cat movie.avi | mplayer -
For my part, I never encode to avi....
There are 10 types of people in the world.
Those that understand binary and those that don't.
