[MEncoder-users] handling stupid mpeg-4 decoder (ffmpeg works but mencoder doesn't)

[Se Heon Ryu]

my mobile has fastidious mpeg-4 decoder.

mencoder -mc 0 -of lavf -oac lavc -ovc lavc -lavfopts format=mp4
-lavcopts threads=2:acodec=libfaac:abitrate=256:aglobal=1:vcodec=mpeg4
:vbitrate=768:vglobal=1:vqscale=2:mbd=2:trell:v4mv -af lavcresample=44100
-vf expand=aspect=5/3,scale=400:240,harddup blah -o blah

makes compatible file but decoder in phone lacks deblocker and makes
unbearable block artifacts
besides even default key_int makes crazy p frame artifacts.


so I switched to xvid but couldn't get working files on mencoder.
tried changing every xvidencopts and found that only

ffmpeg -vcodec libxvid -s 400x240 -b 768000 -acodec libfaac -ac 2 -ar
44100 -ab 256000 -f mp4 -i blah blah

works on mobile and it gives resonable quality.
below is some detail about working xvid file. (though I can't maintain
aspect ratio in ffmpeg yet)

knowing which profile to use and which library it should use I tried

mencoder -mc 0 -of lavf -oac lavc -ovc xvid -lavfopts format=mp4
-lavcopts acodec=libfaac:abitrate=256:aglobal=1 -xvidencopts bitrate=768
:max_bframes=0 -af lavcresample=44100 -vf
expand=aspect=5/3,scale=400:240,harddup blah -o blah

and it gives same detail about file. but not playable on mobile :-(

Spending 8 hours 0am~4am*2days I'm getting exhausted.
I just need precise mencoder command which does what

ffmpeg -vcodec libxvid -s 400x240 -b 768000 -acodec libfaac -ac 2 -ar
44100 -ab 256000 -f mp4 -i blah blah

does.

Sorry for exhaustive post...
Any help would be appreciated.
