und output.mp4. Wenn ich diese Datei ausführe, wird sie sofort beendet, ohne dass Bilder angezeigt werden. Ich sehe keine Fehler oder Probleme im Code, daher bin ich mir nicht sicher, was ich falsch mache. Muss ich die Videoframerate oder etwas anderes erhöhen?

Answer 1

Einige Player haben Probleme mit niedrigen Frameraten. Außerdem wird das Pixelformat möglicherweise nicht vom Player unterstützt.

Verwenden

ffmpeg -framerate 1/5 -i image-%03d.JPG -r 5 -pix_fmt yuv420p output.mp4
