Well, it is a bug. I missed it when it was first committed.

link->current_pts is updated when request_frame() returns EOF. But to
make it work, it would be necessary that the application injects the
timestamp when marking EOF, which is not yet done, but hopefully I will
have time to work on it in the next two weeks.
But it is the correct way of doing things. Using the duration has too
many drawbacks.
