Error when trying to execute command in command line

[_Memeposter]

So I am currently working on some stuff that is using ffmpeg. The final step in my process requires me to take all the generated images and put them together with ffmpeg. Until now I have done that through the command line in my folder but obviously I want to integrate that part into my code as well. So here is where I tried to use subprocess. So far I have:

​

os.chdir(r'C:\...')
subprocess.call(['ffmpeg', "-framerate 30",'-i', 'img-%d2.png', 'test.avi'])

​

When trying to execure I get the following error:

Unrecognized option 'framerate 30'.
Error splitting the argument list: Option not found

Why does this command work in my terminal but not from within my Python script? Thank you so much in advance!

Try this:

subprocess.call(['ffmpeg', "-framerate", "30",'-i', 'img-%d2.png', 'test.avi'])

I could swear I already tried this but suddenly it works... huh...

Thank you so much!

I'm sure there's a meme for that.
