But file mymov.mp4 could not be played in my cellphone! Please give me some advice, thank you very much. When encoding with mencoder, use the option -ffourcc DX50 . This is sometimes necessary for your video to be recognized by a player (see the man page for details).

Try these options, they have a greater chance of working (see the documentation for their meaning): First pass: mencoder -ffourcc DX50 -o mov.avi -ovc lavc -vf scale=400:240,harddup -lavcopts vstrict=0:keyint=32:mbd=2:trell:v4mv:last_pred=3:predia=3:dia=3:cbp:preme=2:vbitrate=512:vpass=1:turbo -oac faac -faacopts br=128 mov.rmvb Second pass: mencoder -ffourcc DX50 -o mov.avi -ovc lavc -vf scale=400:240,harddup -lavcopts vstrict=0:keyint=32:mbd=2:trell:v4mv:last_pred=3:predia=3:dia=3:cbp:preme=2:vbitrate=512:vpass=2 -oac faac -faacopts br=128 mov.rmvb _______________________________________________ MEncoder-users mailing list MEncoder-users@mplayerhq.hu https://lists.mplayerhq.hu/mailman/listinfo/mencoder-users --------------------------------- 雅虎邮箱，您的终生邮箱！ --------------------------------- 雅虎邮箱，您的终生邮箱！
