Seltsame Fehler in ffmpeg bei der Suche nach "Co-lokalisierten POCs nicht verfügbar", "mmco: unref kurzer Fehler"

Question

Ich habe gesehen, dass andere Leute das Problem haben, aber ich habe keine Lösung gesehen. Wenn ich versuche, mit ffmpeg zu suchen, werden einige Fehler angezeigt, und das resultierende Video friert zu Beginn eines Frames ein, bevor es verschoben wird. Selbst wenn ich das Video in VLC öffne, kann ich nicht genau nach dem Punkt suchen, an dem das Problem auftritt. Es scheint, dass das Video irgendwie beschädigt ist, aber es läuft gut, kann es behoben werden?

Wenn ich das Containerformat der Eingabe von ts auf mp4 ändere, tritt der Fehler nicht auf, aber anstelle des eingefrorenen Frames habe ich einen schwarzen Bildschirm.

Voller Befehl und Ausgabe:

$ ffmpeg -ss 5.5 -i video.ts -to 10 -avoid_negative_ts make_zero -vcodec libx264 -crf 23 -acodec copy output.ts

Answer 1

Gelöst ... zuerst:

ffmpeg -i video.ts -c copy video.mp4

und dann statt:

ffmpeg -ss 5.5 -i video.mp4 -to 10 -avoid_negative_ts make_zero -vcodec libx264 -crf 23 -acodec copy output.ts

Sie machen:

ffmpeg -ss 5.5 -i video.mp4 -ss 0 -to 10 -avoid_negative_ts make_zero -vcodec libx264 -crf 23 -acodec copy output.ts
