Estoy haciendo un timelapse con mi RPI en Python.
Para tomar imágenes y almacenarlas en carpetas: Cero problema. Pero para crear un vídeo con FFMPEG tengo un problema.
Después de X imágenes, el script inicia la creación de un vídeo. Da como resultado un video con solo el primer cuadro Y sobrescribe todas las imágenes en la carpeta con el primer cuadro (?!). Ningún mensaje de error.
Entonces ¿qué estoy haciendo mal?

He probado esto y todo está bien:https://lindevs.com/install-ffmpeg-on-raspberry-pi/

Solución rápida: coloque el nombre del archivo de entrada entre comillas simples ( ffmpeg … -i '…/*.jpg' …).
Explicación más larga: el problema es que *su shell expande el archivo a la lista de nombres de archivos antes de que ffmpeg los vea.
Entonces, tu comando original es incorrecto:
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
Se llamará a ffmpeg con una lista de imágenes, esencialmente:
-i image1.jpg image2.jpg …
Para ffmpeg, el segundo archivo de imagen se interpreta como un nombre de archivo de salida. Como pasó -y, ffmpeg felizmente sobrescribirá esta imagen. (Tenga en cuenta que, -ycomo opción global, debe ir primero en la lista de argumentos).
Lo que necesitas hacer escita el comodín. De esta manera, su shell no lo interpretará ni lo pasará a ffmpeg, lo que expandirá internamente el comodín a la lista de imágenes en la carpeta.
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
Ver también los ejemplos.aquí.
Para el código de su programa, recomendaría usar cadenas en formato Python y aprovechar el subprocessmódulo en lugar de llamar directamente 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
)
Aún mejor, coloque todo el contenido del comando en una lista y páselo:
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",
])
