I recompiled a CVS-version that i retrieved from the cvs repository,
yesterday.

Compiled options (from the top of my head):

libdvdread + decss
Xvideo
SDL
DivX4linux
gtk (for --enable-new-gui)

I havent had the chance to listen to the sound, yet, but i can confirm
that the problem with -autoq and frames "flashing" that i had with the
stable 0.50 version has indeed been fixed (or rather, it works fine with
the new code ;)

So far, so good. It compiled perfectly fine with the debian/rules setup
(added --enable-new-gui) and is now installed as a .deb (wonderful way of
testing different versions... _thanks_ for supplying this! ;)

Furthermore, i'm currently loving the way mencoder works :))
I'm encoding a pr0n dvd at the moment, doing the 2nd pass right now. It
seems to work pretty perfectly :)
I'd indeed also be very interesed in a -split option, aswell as the
re-scaling filter that's already planned.

For mplayer itself, it might be nice to be able to switch between aid's on
the fly using some key-combo. Just a thought... aswell as the
fullscreen-switching in the -vo Xv output plugin ;)

I hope to check the sound, tonight.


Oh yes, what are the chances of beign able to effectively use SMP support
for mencoder ? ;)
Or, maybe a MPI-like setup which takes a few frames of vob-data and sends
it to several CPU's to encode, retrieve the output and paste it together
into one output file.
This'd enable you to do use multiple CPU's on the same system (local
threads) aswell as maybe encode a full DVD in a few minutes on your
office's LAN, at night ? ;)
(I'm already toying with a script setup that basically uses SSH and
mencoder to produce .avi's of a few frames of .vob... Now just hope that i
can stick them all together nicely afterwards.., probably not. I'm
guessing there's gonna be a lot of skipping and jumping and other weird
effects ? or will it work nicely because it splits it before/after
keyframes ? ;)
Ah well.. time for more play...
