create a movie with python

[Ofnuts]

To run command line programs from within my script I used subprocess.

First I added import subprocess and then:

subprocess.call("avconv -framerate 1 -i fig%06d.png -c:v libx264 -profile:v high -crf 20".split())

Now, although I can see the saved *.png in my Folder but still I CAN'T create a movie. I don't know what do I have to do to correct the code to create a movie. ANY SUGGESTION???

If you issue the bare avconv command in a terminal/command prompt does it work?

Otherwise the whole thing runs in python, exits normally, and you don't get any error messages and the return code from the avconv call is 0?
