Avconv command to combine image and audio file (to create a video)

Question

Trying to perform a simple task: combine an image file with an audio file to create a video. I've already found a few examples using ffmpeg, but I'm using a cloud-based PythonAnywhere and they only use avconv.

Code would look something like this:

import os
image_file = "/dir/greenfrog.jpg"
audio_file = "/dir/AudioFile.wav"
output_file = "/dir/VideoFile.mp4"
cmd = xxxxx
os.system(cmd)

How should I write the cmd string to combine the two files? Thanks for your help here...
