[MEncoder-users] mencoder skipping frames

[Manuel Kampert]

Hello!

 

I have captured some of my old video8 video material to my PC via

 

mencoder tv:// -tv
driver=v4l2:norm=pal:input=1:fps=25:alsa:amode=1:audiorate=48000:width=768:h
eight=576 

-oac lavc -ovc lavc -lavcopts
vcodec=huffyuv:format=422p:acodec=mp2:abitrate=224"

                

everything fine so far. (I got about 8-10 skipped frames for one hour of
video material).

 

Now it is where everything goes bad :-( I am trying to convert this material
to some format that needs less space.

 

mencoder -oac copy -ovc lavc -lavcopts vcodec=mpeg2video -o out.mpg in.avi

 

gives me a skipped frame every 10 frames. 

 

To do the work I have used MEncoder dev-SVN-rUNKNOWN-4.1.2 on Gentoo.

 

Is there anything obvious that I have done wrong? I have even tried this on
an AMD and an Pentium4 machine. I have also

tried using ac3 as an audio codec without any difference.

 

Regards, 

  Manuel
