[XviD-devel] [Feature Request] Global first and second passes

Hi @ all !
Sometimes I have to encode a ~26 files pack (episodes) and define a
total size (4.7GB). Actually I define a "static" file size (eg. 4700 /
26 = 180MB per file).
But this is not really optimized for obtaining a constant quality
because some episodes needs more bitrate than other ones.
This is why I think there is a needed feature on XviD we could call
"segmented passes" or "global pass".
We need the ability to concatenate a "first pass file" with another
"first pass file" and then we will be able to define a global size for
all the segments (4700 MB).
Then @ second pass, XviD encoder will have to read our "big first pass
file" and output these segments.
example :
- 01.avi (190MB)
- 02.avi (150MB)
- ....
- 26.avi (200MB)
TOTAL : 4700 MB
