[MEncoder-users] 2pass encoding

[double]

Hi,

I have a problem with On2 VP6 2-pass encoding. The first pass works
but the second pass stops without error message (meaning: it doesn't
do anything).
You find the complete output of the second pass below. Until it stops,
the output is identical with the output of the first pass.

Here are my command lines:

wget http://www.doppelbauer.name/source.asf
wget http://www.doppelbauer.name/p1.mcf
wget http://www.doppelbauer.name/p2.mcf

mencoder source.asf -o output.flv -vf yadif,scale=320:240,flip
      -of lavf -lavfopts 
i_certify_that_my_video_stream_does_not_use_b_frames
      -ovc vfw -xvfwopts codec=vp6vfw.dll:compdata=p1.mcf
      -oac mp3lame -lameopts cbr:br=64

mencoder source.asf -o output.flv -vf yadif,scale=320:240,flip
      -of lavf -lavfopts 
i_certify_that_my_video_stream_does_not_use_b_frames
      -ovc vfw -xvfwopts codec=vp6vfw.dll:compdata=p2.mcf
      -oac mp3lame -lameopts cbr:br=64

Thank you very much.
Markus
