No, you don't need this information. Our RTP reception implementation
takes care of this automatically, so that your receiver is presented
with whole, properly-ordered frames.
If, however, you really want to look at the QOS (including packet loss)
statistics that the RTP/RTCP reception implementation collects, then you
can do this by looking at the "RTPReceptionStats". See, for example,
how the "openRTSP" demo application implements its "-Q" option.
But, in Microsoft Directshow, when you provide a sample to downstream
filter, you can indicate that if there is a discontinuity in the stream. I
think this info is useful to other receivers too.
Thanks,
Dong
