Ich versuche, den Container eines von einem NVR empfangenen Videos mit zu ändern ffmpeg, aber das Ausgabevideo kann nicht mit VLC oder QuickTime abgespielt werden. Das Ausgabevideo bleibt stehen. Genauer gesagt, mit dem folgenden Befehl:
ffmpeg -i input.avi -c:v copy output.mp4
Ich erhalte folgende Fehler- und Warnmeldungen:

Irgendwelche Vorschläge, wie man den Container ohne erneute Kodierung ändern kann?
Antwort1
Sie verwenden die Option -c:v. Sie wird normalerweise zum erneuten Kodieren von Videos verwendet.
Verwenden Sie sie einfach so:
ffmpeg -i input.avi output.mp4
