  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;

  • ffmpeg can't change number of B-frames

    10 juin 2021, par user1315621

    When streaming from a source I keep receiving frames following the same pattern :
I-frame P-frame I-frame P-frame I-frame P-frame ....
I tried many options and read as many questions here as I found, but I can't find a way to increse the number of P-frame or at least enable B-frames.

    


    Mainly it seems that I should use :

    


     ffprobe rtsp://localhost/video -g 30 -bf 3 -show_frames -of csv


    


    What am I doing wrong ?

    enter image description here

    Basically, I would like to pass to the shell, a command that allows me to output a particular frame number (say frame number 200) with the motion vectors drawn into it.

    Any clue ? Thanks in advance.

  • dxva2 : Increase maximum number of slices for mpeg2

    6 mars 2014, par Rainer Hochecker
    dxva2 : Increase maximum number of slices for mpeg2

    Some content requires an higher number of slices in order to
    
render properly.
    

    Rise the number to 1024 and warn if ever it exceeds.
