[MPlayer-users] encoding thinks "nothing to do" ?

[Meino Christian Cramer]

Hi,

 From the manual (file:
 http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-enc-libavcodec.html,
 Chapter "13.3.4. Encoding setting examples" I copied the according
 parameter string into a script:

 The parameter string can be found under "Very high quality" in the
 first text box. It is:

  vcodec=mpeg4:mbd=2:mv0:trell:v4mv:cbp:last_pred=3:predia=2:dia=2:vmax_b_frames=2:vb_strategy=1:precmp=2:cmp=2:subcmp=2:preme=2:qns=2	

 The resulting script was:

    #!/bin/zsh
    mencoder $2 -ovc lavc -lavcopts vcodec=mpeg4:psnr:mbd=2:mv0:trell:v4mv:cbp:last_pred=3:predia=2:dia=2:vmax_b_frames=2:vb_strategy=1:precmp=2:cmp=2:subcmp=2:preme=2:qns=2 -oac copy -vf $1 -o $3
    
 With: $1: cropping values
       $2: input video
       $3: outpüut video

 I started that script to encode a video.

 The output was:

 The encoding process stops immediately after starting the script with
 a 28kb long result (input was about 2Gb)

 I cannot figure out, what was going wrong here, since the output does
 not differ significantly (at least for me ... ;) from those done when
 encoding with the same video input works quite well (but I wanted 
 picture quality to be better...)


 Thank you very much for any helpful reply in advance !
 Kind regards,
 mcc
