I am doing a timelapse with my RPI in python.

To take images and store them in folders: Zero problem. But to create a video with FFMPEG I have a problem.

After X images, the script launches the creation of a video. It results in a video with only the first frame AND it overwrites all images in the folder with the first frame (?!). No error message.

So what am I doing wrong?

system('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' %( nom_premiere_image, nom_dossier, nom_sous_dossier, nom_dossier, nom_sous_dossier, nom_sous_dossier))

  • Is this an actual programming issue, or just an issue with ffmpeg? This site is not for programming-related questions. It's hard to tell what your code does without running it. Could you please edit the question in such a way that you only show what ffmpeg command you are actually executing? Please also show the entire output of the ffmpeg command. – slhck Jun 24 '22 at 18:19
  • hello ok i did what you said :) – lensemble Jun 24 '22 at 21:14
  • Please show the actual ffmpeg command. Make it a string variable and just print it rather than calling `system`. – slhck Jun 26 '22 at 06:07
  • @slhck can you show me an exemple ? – lensemble Jun 26 '22 at 13:35
  • @rotem i have edited my question, and i hope i did what you asked – lensemble Jun 26 '22 at 13:36

Quick solution: put the input filename into single quotes (ffmpeg … -i '…/*.jpg' …).

Longer explanation: the problem is that the * gets expanded by your shell to the list of filenames before ffmpeg even sees them.

So, your original command is wrong:

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 will be called with a list of images, essentially:

-i image1.jpg image2.jpg …

For ffmpeg, the second image file is interpreted as an output filename. Since you have passed -y, ffmpeg will happily overwrite this image. (Note that -y as a global option should go first in the argument list.)

What you need to do is quote the wildcard. This way, your shell will not interpret it and pass it on to ffmpeg, which will internally expand the wildcard to the list of images in the folder.

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

See also the examples here.

For your program code I'd recommend to use Python format strings and leverage the subprocess module instead of directly calling 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
)

Even better, put everything in the command into a list and pass that:

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",
])
