  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • lavc/vvc : Validate IBC block vector

    lavc/vvc : Validate IBC block vector

    From H.266 (V3) (09/2023) p. 321 :
    

    It is a requirement of bitstream conformance that the luma block
    
vector bvL shall obey the following constraints :

    - CtbSizeY is greater than or equal to
    
((yCb + (bvL[ 1 ] >> 4)) & (CtbSizeY − 1)) + cbHeight
    

    This patch checks this is true, which fixes crashes on fuzzed
    
bitstreams.

  • ffmpeg video processing command does not end

    24 août 2023, par Harry

    I am using ffmpeg to create a video processing lambda, I attached the log for the processing input below and the process never completes sometimes and other times it takes no more than 2 minutes. This also does not throw and error but just does not complete for certain videos.

    The intention is to provide two videos with varying lengths and have them stack on top of each other vertically with subtitles and a length of the shortest video.&#xA;I am running the function in a lambda and even with a timeout of 10 minutes it does not complete for certain videos but for others it does complete, please help me to resolve this.
