  • .mov conversion to .mp4 using ffmpeg doesn't convert the entire video

    5 février 2013, par user504879

    I am trying to convert a mov file which I got from saving my powerpoint presentation to a movie file. However only a part of the presentation is converted not the entire one and also running qt-start doesn't make the exported mp4 to stream over rtmp. Is there something which I am missing ?

    I am attaching the output which i get when I am trying to convert the file using ffmpeg
