[MEncoder-users] Closing all GOPs

[Julio César Carrascal]

Hi.

First time posting here. I've been searching the archives for this
subject but hasn't found anything related. Last couple of days I was
trying to obtain a dvd file that programs like Nero and Sony DVD
Architect accept as compliant to DVD standards but didn't have any
luck. They always complain and try to re-encode the movie with the
corresponding quality loss.

A friend recommended me to use Mediachance DVD-Lab wich could tell me
what was wrong with my file. I've fixed all errors and warnings that
DVD-Lab gave me except for one:

Close ALL GOPs

The corresponding lavc option says it isn't implemented. This is the
batch I'm using:

@echo off

set input="%1"
set output="%2"

set opts=-endpos 60 -ss 360 -ofps 24 -oac copy -ovc lavc -srate 2145
-vf expand=704:456,scale=740:480,harddup,softskip -noskip -mc 1 -of
mpeg -mpegopts format=dvd:telecine
set pass1opts=%opts% -lavcopts vcodec=mpeg2video -lavcopts
vcodec=mpeg2video:vbitrate=4500:aspect=4/3:turbo:vpass=1
set pass2opts=%opts% -lavcopts vcodec=mpeg2video -lavcopts
vcodec=mpeg2video:vbitrate=4500:aspect=4/3:vpass=2

mencoder -o %output% %input% %pass1opts%
mencoder -o %output% %input% %pass2opts%

Is there any way around? Any idea when will it be implemented?

Thanks.
