Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur
8 février 2011, parLa visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

I use ffmpeg to format videos according to tik-toke standards [closed]
8 mai 2024, par John RedI use ffmpeg to format videos according to tik-toke standards, but I don't know why videos are not cropped and lose quality.


const transcode = async () => {
 const ffmpeg = ffmpegRef.current;
 await ffmpeg.writeFile('input.mp4', await fetchFile(file));
 await ffmpeg.exec([
 '-i', 'input.mp4',
 '-vf', 'scale=1080:1920,crop=ih*(9/16):ih',
 'output.mp4'
 ]);
 const data = await ffmpeg.readFile('output.mp4');
 videoRef.current.src =
 URL.createObjectURL(new Blob([data.buffer], { type: 'video/mp4' }));
}



Changed the resolution and cropped it. It didn't help in any way, only lost quality. Not what I wanted at all.

Trying to combine videos losslessly with ffmpeg
16 novembre 2016, par Jarppii am trying to create bath that would automatically join multiple videos that are in folder (liimattavat) and that would make them to .ts files in (roska) and after that it would just combine them all without quality loss to (valmis.mp4)
but i dont seem to get it working as i get something like path doesn’t exist@echo off

for %%a in ("roska\*.ts") do "concat:"roska\*.ts" -c copy -bsf:a aac_adtstoasc valmis.mp4
