I had thought about something to handle timestamps discontinuities / lost
frames, but not very deeply.

In my mind, commands are an extra feature to change the filtering process
while these messages are necessary for normal encoding (the current system
is broken wrt the duration of the last frame). Do you have an inkling about
a better name? Metaframe?

Also, I would like your advice on the avframe-on-stack micro-optimization.
