    Hi, I downloaded a video and as my tv doesnot support auio m4a, i tried to change the audio to mp3 using the following command
    ffmpeg -i input.avi -acodec mp3 -vcodec copy out.avi substituting with my files.
    the proces went smooth and i got the mp4 output with a slight increase of file size.
    The video ran well for about 11/2 hour of 2 hour movie without any sync problem
    But after that, suddenly the audio overtakes the video and finishes first and the video closes later.
    So, the play turned to a joke, by vdeo showing a male and a female voice, because of sync.
    what is the reason for such thingss
    Is there any fix for it.
    Should i change something in the formula
    i must say that there is no quality loss of video or audio
    expecting solutions
