[MPlayer-users] Encoding with libx264

I tried a lot of options with mencoder and H.264 codec (libx264 from lavc and x264enc) and nothing works.
It seems that mencoder does not support H.264 codec any more as runtime messages display "broken ffmpeg default settings detected" and propose options not supported by mencoder. So the mencoder man pages are outdated !
So, could you confirm that mencoder does not support encoding with H.264 codec family ?
Thank you.
