Ffmpeg ne concatège pas correctement les fichiers multimédias en utilisant divers tests. L'une des vidéos est une vidéo .mp4 (codec h264) générée précédemment à l'aide d'un fichier .mp3 et d'un arrière-plan jpeg. J'ai essayé de tester avec différents drapeaux, le plus proche que j'ai eu est ci-dessous pour la sortie finale.ffmpeg concat avec vidéo utilisant l'arrière-plan de l'image
Mon problème principal est la vidéo finale avec le test en cours, l'audio est retardé d'environ 3 secondes une fois que les deux vidéos sont assemblées.
Voici tous les fichiers que je utilise:

'mpdecimate' va supprimer les trames dupliquées. Pour une vidéo créée à partir d'une seule image, c'est ** toutes les images ** après la première! Pourquoi ce filtre est-il là? – Mulvya
Je ne faisais que le tester, quand j'utilise mpdecimate, la seconde vidéo a la bonne longueur, mais quand je n'utilise pas ce filtre, la première vidéo est beaucoup plus longue et finit par être environ 10 fois plus longue que la vidéo créée avec le fond de jpeg. –
