How does it know which frames are missing?
Automatically. By compare every two consequent frames.
Can it use the audio track as the "measuring stick"?
Not for now. Why you ask it? You told audio is perfect. Without any missed chunks.
Or I don't understand you. Please upload sample with drops and I will take a look to "out of sync" you are talking about.

It is not hard to start. Give me samples with drops I will help you.
