[MPlayer-users] mpeg files by mencoder don't work under Windows

[Joonas Koivunen]

hey there,

I was just trying to encode some clips to my friend, who wishes to put
those clips to a dvd he's been gathering up. I have the latest
released mplayer/mencoder, which is MPlayer 1.0pre7.

The problem seems to be that when I transfer the "-of mpeg" files to
windows (my friend tries to build the dvd with Adobe Encore), none of
the windows players are able to show the video in the files (which
have mp2 audio (lavc) and mpeg2 video (lavc)), only the audio.

If I do "mencoder -o test.mpg -of mpeg -nosound -ovc copy
transcoded.mpeg", windows players will be able to show the video, but
it's framerate varies a lot. At some points it seems to decode as many
as possible frames, otherwise it decodes them at normal speed.

I have a Athlon XP 1800+ based system so I doubt that any cpu shortage
can cause the strange playing under windows..

The line used to create the mpeg's was something along the lines of
(all sources were already 25fps):
"mencoder source.avi -oac lavc -ovc lavc -vf
crop=....,pp=md,scale=720:576 -lavcopts
acodec=mp2:vcodec=mpeg2video:vbitrate=3500:abitrate=128:vhq:trell:autoaspect
-of mpeg -o output.mpg"

(I didn't really pay attention to the aspect because it can be fixed
in the mastering phase.)

Is there something catastrofally wrong with those parameters? Oh yeah,
I almost forgot. mplayer is able to play all the files created by
mencoder just fine. If only all other players were as flexible...
