Well, I think that this should be application's decision, and not a policy
hardcoded in the library... If we deliver all the frames to the
application (marking the ones with unreliable PTSs), it is of course free
to discard the first frames, until the PTSs become reliable.

I am with you on this... Everything the application has to do is to discard
first frames having PTS = AV_NOPTS_VALUE.
