You mean "packet", not "package".

Actually, it would be even better if the first RTCP "SR" packet were
sent *before* the first RTP packet, for the reason you state. I
think the RTP specification allows this (for unicast streams, at
least), and so this is something we may end up doing someday.
(In any case, though, a client must always allow for some RTP packets
to be received before the first RTCP "SR" packet is received - i.e.,
before properly time-synchronized presentation times can be inferred
from the RTP packets.)
