If you're using Linux, you'll need a few changes:

FFMPEG_BIN = 'ffmpeg.exe'
to:
FFMPEG_BIN = 'ffmpeg'

and

command = [ FFMPEG_BIN,
        '-y', # (optional) overwrite output file if it exists
        '-i', audio_filename,
        '-i',video_filename,
        '-acodec', 'copy',
        '-vcodec', 'h264',
        filename ]

to:

command = [ FFMPEG_BIN,
        '-i', audio_filename,
        '-i',video_filename,
        '-acodec', 'copy',
        '-vcodec', 'h264',
        filename ]

Tested in Fedora 26.

What if there is no master.json?
