[MPlayer-users] Mencoder Problem with mp3lame and dual core xeon

[Philip Schierholz]

Hi.

I've got a problem with Mencoder.

I tried to transcode VDR-Files with Mencoder. For the videostream I used lavc mpeg4, which worked well. For example:

mencoder 001.vdr -ovc lavc -lavcopts vcodec=mpeg4:mbd=2:trell:vbitrate=600:autoaspect -vf scale=384:288 -oac copy -o ARD_2007-06-28-1200_BitR_600_Scale_384_288.avi

Now I want to encode the audiostream to mp3. First I tried lame (version 3.97) but it didn't work!

commandline:
mencoder 001.vdr -ovc lavc -lavcopts vcodec=mpeg4:mbd=2:trell:vbitrate=600:autoaspect -vf scale=384:288 -ffourcc DX50 -oac mp3lame -o ARD_2007-06-28-1200_BitR_600_Scale_384_288_mp3lame.avi

Audio LAVC, couldn't find encoder for codec mp3.

=================================

What can I do to make it work? I tried to encode an mp2 audiostream with lame directly and it worked.

Second Question: I use a Xeon Dual-Core Machine for the transcoding jobs. The Mencoder uses only on CPU. How can I use the power of both CPUs for the job?

Tranks for help.
Philip

I prefer answers in German...
