[MPlayer-dev-eng] difference in vobsub handling between mplayer and mencoder

[Pomarede Nicolas]

Hello,

I hope this is the right list for reporting this (since this looks like a 
bug, I guess it might be).

I noticed 2 differences between mplayer and mencoder when playing the same 
matroska file.

I use mencoder to reencode the mkv file in RV40 to divx4. So I have 2 
files : in.mkv, out.avi.

  - with mplayer, the vobsub subtitles in in.mkv are displayed nearly at 
the bottom of the screen (which is OK), but when mencoder creates the new 
file, the vobsub are near the center of the screen, which is too high. If 
I use -spualign 2, both videos displays the subtitle at the same place, so 
this fix the problem, but it seems mplayer and mencoder don't handle the 
default value in the same way.

  - a more annyoing problem is that the subtitle don't have the same color 
when reencoded. In in.mkv, they're white with a black outline, but in the 
out.avi file, they become black with a white outline, which is harder to 
read. Is there a way to keep the same color ?

I'm using the following command :

mencoder in.mkv -oac lavc -ovc lavc -aid 1 -sid 1 -spualign 2 -spuaa 2 -lavcopts vcodec=mpeg2video:vbitrate=5000

(using spuaa or not doesn't change the color problem)

This is using 1.0pre7, I don't know if this is fixed in CVS, so I prefer 
reporting it.

Bye
