  • Can ffmpeg place Mp4 metainfo at the beginning of the file ?

    Source : http://www.stoimen.com/blog/2010/11/12/how-to-make-mp4-progressive-with-qt-faststart/

    vaapi_decode : Ignore the profile when not useful

    Enables VP8 decoding - the decoder places the the bitstream version
    
in the profile field, which we want to ignore.
