[MPlayer-users] Creating DIVX for Xoro HSD 400 with mencoder.

[Carsten Koch]

Hi,

I have been trying to create a DIVX CD with mencoder for my
DIVX-capable DVD player (Xoro HSD 400).

The DIVX file created can be played fine with mplayer, but
the DVD player does not recognize it.
All it does is show me a playing time of 0:00:00 and a
black picture with no sound.

I tried

mencoder source.mov -ovc frameno -oac mp3lame -lameopts vbr=3 -o frameno.avi
mencoder source.mov -oac copy -ovc lavc -lavcopts vcodec=mpeg4:vpass=1:vbitrate=991
mencoder source.mov -oac copy -ovc lavc -lavcopts vcodec=mpeg4:vpass=2:vbitrate=991

and

mencoder source.mov -ovc frameno -oac mp3lame -lameopts vbr=3 -o frameno.avi
mencoder source.mov -oac copy -ovc lavc -lavcopts vcodec=msmpeg4:vpass=1:vbitrate=991
mencoder source.mov -oac copy -ovc lavc -lavcopts vcodec=msmpeg4:vpass=2:vbitrate=991

to create the DIVX file.

mplayer plays itc back correctly and says

AVI file format detected.

For testing purposes, I also wrote a DIVX file that was *not* created with mencoder
to a CD. That one works fine, so the problem has nothing to do with cdrecord or
my CD-R media. It also proves that the Xoro HSD 400 DVD player can indeed play
back DIVX files from an ISO 9660 data CD-R.

For the *working* DIVX file, mplayer says:

AVI file format detected.

My questions are:

*  What is the difference between
	VIDEO:  [DIV3]
    (which works on the DVD player)
    and
	VIDEO:  [div3]
    (which does not work on the DVD player)
    In other words: What difference does mplayer indicate with the upper case
    versus lower case div3?

*  Could the  44100 Hz vs. 48000 Hz be the reason for the problem?
    If yes, what are the best mencoder parameters for audio resampling to 48kHz?

*  Any other suggestions what I could try?

Thanks and cheers,

Carsten.
