[MPlayer-users] Reencoding/concatenating to minimize number of disks?

[Svante Signell]

Hello,

An advice on how to re-encode two XVID/DIVX to SVCD's as efficiently as
possible would be very much appreciated. Using the mencvcd script (in
the TOOLS directory of mplayer-cvs) every XVID image generates more than
one (or one if you are lucky) SVCD image due to the different
compression efficiencies. For example 2 DIVX files could instead of 4
SVCD's be reduced to 3 if done properly.

Different alternatives are possible:
(other unimportant stuff omitted here)

1. cat 1.avi 2.avi > total.avi
   mencvcd -vnorm p -a 2 -svcdout total.avi
2. mplayer -vo yuv4mpeg -ao pcm | yuvscaler -O SVCD
   cat 1.mpv 2.mpw > total.mpv
   cat 1.wav 2.wav > total.wav
   mp2enc -b 224 -r 44100 -o total.mpa < total.wav
   mplex -f 4 -o total.mpg total.mpa total.mpv
   vcdimager -t svcd -c total.cue -b total.bin  total.mpg
3. other alternatives?

Any issues with audio/video synch?
Which methods preserves the synch and which metods don't?
What if the video/audio rates/encoding/etc differs?

Thanks,
Svante
