  • 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.

  • FFMPEG : cut clips from a long video with "fast seek" while maintaining accuracy

    15 août 2020, par japseow

    I have this 3 hour long video which consists of <1-5 seconds of black frames> — < clip > — <1-5 seconds of black frames> — < clip > — ...

    &#xA;

    I could successfully get the clip without the black frames with the slow seek, but it takes over 4 minutes just for seeking.

    &#xA;

    ffmpeg -y -i "C:\Users\user\Videos\obs\part1.mp4" -ss 4370.48 -to 4384.95 -c:a copy -c:v hevc_nvenc -rc vbr_hq -cq 19 -b:v 10000k -maxrate:v 12500k "C:\Users\user\Videos\obs\____delete1.mp4"

    &#xA;

    I tried using the fast seek which takes only 4 sec, but it includes a 4 sec blackframe chunk at the end of the video. The output that should've been 14 sec long became 18 sec.

    &#xA;

    ffmpeg -y -ss 4370.48 -i "C:\Users\user\Videos\obs\part1.mp4" -to 14.47 -c:a copy -c:v hevc_nvenc -rc vbr_hq -cq 19 -b:v 10000k -maxrate:v 12500k "C:\Users\user\Videos\obs\____delete2.mp4"

    &#xA;

    My video has around 640 clips so it's impractical to wait that long just for seeking, and it'll only get worse when I'll be seeking at around the 2+ hour mark.
