Comment (by native-api):

 This is currently resolved with a workaround, `-vsync cfr`. Is there some
 deep reason why it should stay so?

 Looks like the GIF decoder should instead produce some "end of stream"
 marker with a timestamp at the end. Such a thing may be absent from the
 current object model but it's an intrinsic part of slide show formats by
 their nature.

 (A fake frame at the end instead would also be a workaround 'cuz it would
 distort the real file structure just like the current workaround does.)
