    Hi there,
    I am trying to convert a .wmv video to .flv using mencoder. But after many tryings, still cannot make the audio in sync with the video.

    The basic command I used is:

    mencoder myoriginalvideo.wmv -o output.flv -of lavf -ovc lavc -oac lavc -lavcopts vcodec=flv:vbitrate=500:autoaspect:mbd=2:mv0:trell :v4mv:cbp:last_pred=3redia=2:dia=2recmp=2:cmp=2ubcmp=2reme=2:turbo:acodec=mp3:abitrate=56 -vf scale=320:240 -srate 22050 -af lavcresample=22050 -lavfopts i_certify_that_my_video_stream_does_not_use_b_fram es

    I have tried "-mc 0", "-noskip", "-vf scale=320:240,harddup", "-vf scale=320:240,decimate=-0:99999" or "-vf scale=320:240,decimate=2:1000:1600:.001" etc and their combinations but never worked. To my notice, when "-noskip" was present, too many frames skipped which resulted in video too fast; otherwise many frames were duplicated which resulted in video too slow. I just don't know how to adjust the command to get the right dropping/duplicating point.

    One more thing, the original video codec is Windows Media Video V7.

    Thanks a lot for any help.!

    Helen

    Yeah, good luck on this. Sometimes an app just won't cut it, especially mencoder and audio sync. Try Xvid4PSP or AutoMKV or WinFF(maybe).

    Thanks for your reply! Is there any way can be done using mencoder? I have to use mencoder because it's the tool we chosen to convert many videos to .flv.

    Thanks a lot in advance!
