Cannot use ffmpeg backend

[androidacy-user]

using ffmpeg results in the following:

  File "/usr/local/lib/x86_64-linux-gnu/howdy/compare.py", line 178, in <module>
    video_capture = VideoCapture(config)
  File "/usr/local/lib/x86_64-linux-gnu/howdy/recorders/video_capture.py", line 52, in __init__
    self.internal.grab()
