Ich mache einen Zeitraffer mit meinem RPI in Python.
Bilder aufnehmen und in Ordnern speichern: Kein Problem. Aber beim Erstellen eines Videos mit FFMPEG habe ich ein Problem.
Nach X Bildern startet das Skript die Erstellung eines Videos. Das Ergebnis ist ein Video mit nur dem ersten Frame UND es überschreibt alle Bilder im Ordner mit dem ersten Frame (?!). Keine Fehlermeldung.
Also, was mache ich falsch?

Ich habe Folgendes versucht und alles ist in Ordnung:https://lindevs.com/install-ffmpeg-on-raspberry-pi/
Antwort1
Schnelle Lösung: Setzen Sie den Eingabedateinamen in einfache Anführungszeichen ( ffmpeg … -i '…/*.jpg' …).
Längere Erklärung: Das Problem besteht darin, dass *Ihre Shell die Liste der Dateinamen erweitert, bevor ffmpeg sie überhaupt sieht.
Ihr ursprünglicher Befehl ist also falsch:
ffmpeg -f image2 -framerate 1 -pattern_type glob -start_number %d \
-i /media/julien/USBKEY/capture_%d/%d/*.jpg \
-r 5 -c:v libx264 -pix_fmt yuv420p \
/media/julien/USBKEY/capture_%s/%d/out%d.mp4 -y
ffmpeg wird mit einer Liste von Bildern aufgerufen, im Wesentlichen:
-i image1.jpg image2.jpg …
Für ffmpeg wird die zweite Bilddatei als Ausgabedateiname interpretiert. Da Sie übergeben haben -y, überschreibt ffmpeg dieses Bild problemlos. (Beachten Sie, dass dies -yals globale Option in der Argumentenliste an erster Stelle stehen sollte.)
Was Sie tun müssen, istzitieren Sie den Platzhalter. Auf diese Weise interpretiert Ihre Shell es nicht und gibt es nicht an ffmpeg weiter, das den Platzhalter intern zur Liste der Bilder im Ordner erweitert.
ffmpeg -f image2 -framerate 1 -pattern_type glob -start_number %d \
-i '/media/julien/USBKEY/capture_%d/%d/*.jpg' \
-r 5 -c:v libx264 -pix_fmt yuv420p \
/media/julien/USBKEY/capture_%s/%d/out%d.mp4 -y
Siehe auch die BeispieleHier.
Für Ihren Programmcode würde ich empfehlen, Python-Formatzeichenfolgen zu verwenden und das subprocessModul zu nutzen, anstatt direkt aufzurufen system:
import subprocess
subprocess.check_output(
f"ffmpeg -y -f image2 -framerate 1 -pattern_type glob -start_number {nom_premiere_image} -i '/media/julien/USBKEY/capture_{nom_dossier}/{nom_sous_dossier}/*.jpg' -r 5 -c:v libx264 -pix_fmt yuv420p /media/julien/USBKEY/capture_{nom_dossier}/{nom_sous_dossier}/out{nom_sous_dossier}.mp4", shell=True
)
Besser noch, setzen Sie alles im Befehl in eine Liste und übergeben Sie diese:
subprocess.check_output([
"ffmpeg", "-y", "-f", "image2", "-framerate", "1", "-pattern_type", "glob", "-start_number", nom_premiere_image,
"-i", f"'/media/julien/USBKEY/capture_{nom_dossier}/{nom_sous_dossier}/*.jpg'",
"-r", "5", "-c:v", "libx264", "-pix_fmt", "yuv420p",
f"/media/julien/USBKEY/capture_{nom_dossier}/{nom_sous_dossier}/out{nom_sous_dossier}.mp4",
])
