Problème de code temporel FFMPEG pour IMX 50 Mxf


0

Nous devons transcoder la source au format IMX 50 Mxf et réinitialiser le temps à 00: 00: 00: 00.

Mon fichier source est également IMX 50 avec SOM 09: 59: 55: 00.

J'ai utilisé ci-dessous la commande ffmpeg.

Pas possible avec -c:v copy. Vous pouvez probablement ouvrir un ticket de souhait pour que cela soit ajouté au filtre bitstream des métadonnées mpeg2 à l'adresse trac.ffmpeg.org.
