But I found some issues in it. Got this log :

    Why is this error at the end ?
    and also one folder got created in my /opt/lampp/htdocs/tests_updates/sintel_300kbit.
    which has two types of files :
    27 files of .m4s extension
    1 file -sintelinit.mp4
    1 file- sintel_trailer_2k_480p24_300kbit.mp4 , which when played in vlc player played the video bt no audio ! &

    1 file- sintel_trailer_2k_480p24_300kbit.h264 which cannot be opened.

    No .mpd file was created.

    Also I want to know aft creating that .mpd file how will i be able to test it on my android client say media player.

    I am damn confused with all this happening. Please help.

  • FFmpeg '-bframebias' option gone ? [closed]

    18 mars 2013, par RRN

    Recently I updated ffmpeg to version 1.1, when I run a command containing bframebias, it showed an error :

    Unrecognized option 'bframebias'.
    Error splitting the argument list: Option not found

    This command used to work fine. So the option bframebias is removed or it is replaced by another option ?
