  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.

    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 ?
