    9 novembre 2010, par

    MediaSPIP Core fournit par défaut trois pages différentes de configuration (ces pages utilisent le plugin de configuration CFG pour fonctionner) : une page spécifique à la configuration générale du squelettes ; une page spécifique à la configuration de la page d’accueil du site ; une page spécifique à la configuration des secteurs ;
    Il fournit également une page supplémentaire qui n’apparait que lorsque certains plugins sont activés permettant de contrôler l’affichage et les fonctionnalités spécifiques (...)

  • avformat/mov : avoid seeking back to 0 on HEVC open GOP files

    avformat/mov : avoid seeking back to 0 on HEVC open GOP files

    ab77b878f1 attempted to fix the issue of broken packets being sent to
    
the decoder by implementing logic that kept attempting to PTS-step
    
backwards until it reached a valid point, however applying this
    
heuristic meant that in files that had no valid points (such as HEVC
    
videos shot on iPhones), we'd seek back to sample 0 on every seek
    
attempt. This meant that files that were previously seekable, albeit
    
with some skipped frames, were not seekable at all now.
    

    Relax this heuristic a bit by giving up on seeking to a valid point if
    
we've tried a different sample and we still don't have a valid point to
    
seek to. This may some frames to be skipped on seeking but it's better
    
than not being able to seek at all in such files.

  • Force x264 to only use long term reference frames

    12 décembre 2019, par cloudraven

    I want to generate a h.264 stream in which P-frames are using references exclusively using long-term references identifiers rather than defaulting to a short-term reference given by the previous frame.

    At this point this is an academic experiment to understand the encoding behavior of long-term references and the consequences of forcing frames to refer to a specific frame rather than several.

    It would be great if I could do this from the command line, but if not possible I am open to modifying x264 for this purpose.

    Could anyone point me to where in the source code it is determined :

    • the reference frame / macroblock / partition for the current macroblock
    • changes made to the short term, long term reference frame list
    • whether to use a short term reference frame or a long term reference frame.

    Using another encoder like nvenc is also acceptable.
