Converting jpg's to mp4 using FFmPy

Question

I have a file full of jpg images that I would like to convert into an mp4 video. I have managed to do this on the command line using

cat path/to/pictures/%d.jpg | ffmpeg -f image2pipe -i - output.mp4

However when I try and go about doing it via FFmPy:

ff = ffmpy.FFmpeg(
inputs={'path/to/pictures/%d.jpg': None},
outputs={'output.mp4': None})

ff.cmd
ff.run()

I will run into the error:

    FFRuntimeError: `ffmpeg -i path/to/pictures/1.jpg -f output.mp4` exited with status 1

STDOUT:


STDERR:

I'm really not sure what the issue is here, any change I make results in the same error. Any help would be appreciated, thanks.

Since you know the ffmpeg command which works from the command line, it might be easier to simply call it using subprocess:

import subprocess

cmd = ['ffmpeg', '-i', '/path/to/pictures/%d.jpg', 'output.mp4']
retcode = subprocess.call(cmd)
if not retcode == 0:
   raise ValueError('Error {} executing command: {}'.format(retcode, ' '.join(cmd)))
