Librairies et logiciels spécifiques aux médias
10 décembre 2010, parPour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.
Il est important, après avoir installé apache2, mysql et php5, d’installer d’autres logiciels nécessaires dont les installations sont décrites dans les liens afférants. Un ensemble de librairies multimedias (x264, libtheora, libvpx) utilisées pour l’encodage et le décodage des vidéos et sons afin de supporter le plus grand nombre de fichiers possibles.

Keeping control of your media in your hands
13 avril 2011, parThe vocabulary used on this site and around MediaSPIP in general, aims to avoid reference to Web 2.0 and the companies that profit from media-sharing.

Evolution #3589 (Fermé) : Modification au pointage des résultats de recherche...
9 mars 2021, par cedric -J’ai intégré en adaptant parce que :
- le patch proposé est buggué en se basant uniquement sur$regs[0][0]
qui est le premier résultat trouvé : il faudrait donc itérer sur chaque résultat
- pour le résultat multi-mots, l’algo ne marche pas si bien car si par exemple je cherche "tempete de sable" le "de" est supprimé des regexp car trop court, et donc je n’ai que des match sur tempete et sable
- la distinction mot entier/partie de mot est quand même lourde car il faut donc refaire une preg dans un foreach (sans oublier d’échapper le résultat pour reconstruire une preg) et discutable car si je trouve "baton" dans le mot "batons" au pluriel en quoi ce serait moins bien que dans "baton" au singulier ? Il faudrait donc pousser plus loin l’analyse ce qui va in fine être très couteuxTout bien pesé et regardé, j’ai donc tiré la substantifique moelle du patch qui est de dire "plus le résultat trouvé est long mieux c’est" et ça donne https://git.spip.net/spip/spip/commit/c1ab59cb72c77102ea9b75309c2062ab8d8aa51a : je pondère le poids par la longueur totale des matchs trouvés et non par le nombre de match.
Effet de bord, tous les #POINTS vont fortement augmenter, si quelqu’un utilisait un seuil pour filtrer ses résultats ça va tomber à l’eau (mais c’est pas très grave...)

How to batch add chapters to video
2 juin 2021, par throwaway513I have 20 videos and chapter files in .mp4 and .txt formats. Their filenames are 1.mp4 / 1.txt all the way to 20.mp4 / 20 txt. I want to match the same filename video to same filename chapters.


How to batch add the metadata chapters to these videos in ffmpeg ? I am using windows


for %%a in ("*.mp4") do ffmpeg -i "%%a" -i "%%a.txt" -map_metadata 1 -map 0 "Chapvids\%%~na"



1.mp4.txt : No such file or directory
