Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.
Version mono serveur
La version mono serveur consiste à n’utiliser qu’une (...) -

The duration of the combined video with FFmpeg becomes 0
24 août 2019, par sidoI am developing an app for Android by Unity.
When I merge video and audio with FFmpeg, the duration of the output video file is 0 though it can be played back normally.I tried to set duration when merging, but it didn’t work.
The commands being executed are as follows :
-y -i /storage/emulated/0/Android/data/jp.ne.company.app/files/Record/20190824122116_video.mp4 -i /storage/emulated/0/Android/data/jp.ne.company.app/files/Record/20190824122116_audio.mp3 -t 3 -c copy -map 0:v -map 1:a -shortest /storage/emulated/0/Android/data/jp.ne.company.app/files/Record/20190824122116_merged.mp4
I expected that the duration of the merged file was the value set in MovieTime, but the duration of the actually merged file was 0.
The log is as follows :
