Ich habe zwei MP4-Dateien erstellt - eine fünf Sekunden lange Intro-Datei, die durch das folgende Skript erstellt wird, und das Hauptvideo (etwa eine Minute lang) wird von screen-cast-omatic im MP4-Format erstellt. Wenn ich versuche, sie mithilfe der ffmpeg -f concat -i mylist.txt -c copy outputMethode zu verketten, wird eine Ausgabedatei erstellt, in der die Intro-Datei einwandfrei abgespielt wird. Dann wird das Hauptvideo abgespielt. Das Audio ist in Ordnung, aber das Video ist durcheinander und wird dort verstümmelt.
Bei dieser ffmpeg -i "concat:input1.mpg|input2.mpg|input3.mpg" -c copy output.mpgMethode wird ein Video ausgegeben, das nicht vollständig ist. Ich habe keine Skriptausgabe dazu hinzugefügt.
Können einige dies prüfen und eine Empfehlung abgeben?
Das Folgende ist das Skript und die Ausgabe für die erste Methode von concat:
