Objet : [MEncoder-users] I am not able to simply convert video avi files
into mpeg2 video files

Hello,

I am using the tutorial written in chapter 11.8

http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-vcd-dvd.html


to convert AVI files into SVCD movie files.

 

I am precisely using the command line defined in chapter 11.8.5.5

That is :

mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=xsvcd -vf \
    scale=480:576,harddup -srate 44100 -af lavcresample=44100 -lavcopts \
    vcodec=mpeg2video:mbd=2:keyint=15:vrc_buf_size=917:vrc_minrate=600:\
    vbitrate=2500:vrc_maxrate=2500:acodec=mp2:abitrate=224:aspect=16/9 -ofps
25 -o movie.mpg movie.avi

 

The audio part is not well converted, I have a big noise instead.

I have tried many things but without success.

I have tried to use also as an input a mpeg file which contains already the
right MPEG2_VIDEO and MPEG2_AUDIO format and I get the same noise in the
converted file.

 

I would appreciate any support on this.

 

Best Regards.

Massimo LIGNANI

 

Remark: If I use for the audio part "acodec=AC3" instead of "acodec=mp2",
the sound is good. But this is not what I want to do. I really need mp2 for
the audio codec.
