    I installed and compiled mplayer with memcoder from here->

    I tried to encode vob to mp4 (for PSP)

    found this command line in some tutorial:

    ./mencoder test.vob -oac lavc -ovc lavc -of lavf -lavcopts aglobal=1:vglobal=1:vcodec=mpeg4:acodec=aac -af lavcresample=24000 -vf harddup -lavfopts format=psp -ofps 30000/1001 -vf scale=320:240 -o test.mp4
    but it gave me following error:

    REMEMBER: MEncoder's libavformat muxing is presently broken and can generate
    INCORRECT files in the presence of B-frames. Moreover, due to bugs MPlayer
    will play these INCORRECT files as if nothing were wrong!

    Try appending the scale filter to your filter list,
    e.g. -vf spp,scale instead of -vf spp.

    Audio LAVC, couldn't find encoder for codec aac.
    I know i need to install/recompile mplayer+memcoder with aac libs, but how? where do i find it and how to do it?

  2. Use libfaac instead aac.

    And why not try libx264 instead mpeg4?

    ok i got libfaac but don't know how to add it to mencoder.
    tried adding "libfaac" folder to mplayer directory tree but without any result.

    here's my mplayer dir

    and here are the contents of libfaac dir (dunno if i copied good files)

    i ain't got root access on this server so i had to compile it with --prefix=/tmp/mplayer command

    please tell me how to add libfaac to mencoder, i think adding any other codec will be similar.
