[MPlayer-cvslog] r29666 - trunk/libmpcodecs/vf_expand.c

[reimar]

Author: reimar
Date: Thu Sep 10 18:49:20 2009
New Revision: 29666

Log:
Always keep a backup of the expand values from the command-line, so values
will be recalculated correctly e.g. after aspect change and -vf expand=aspect=4/3
command line.
