I know this question is old, but now there is an excellent wrapper for ffmpeg in Python :
ffmpeg-python. You will find it at https://github.com/kkroening/ffmpeg-python
With it, the command could be achieved this way:
import ffmpeg
ffmpeg
.input('test*.png', pattern_type='glob')
.output('output.avi')
.run()
