Summary	Incorrect RTP statistics (Lost Packets indication not ok)
Classification	Unclassified
Product	Wireshark
Version	1.8.5
Hardware	x86
OS	Windows XP
Status	UNCONFIRMED
Severity	Major
Priority	Low
Component	Dissection engine (libwireshark)

Build Information:

--
When sending an MpegTS over RTP to wireshark, packets are default decodes as
UDP.
When doing a "Decode As RTP", actwards (via Telephony - RTP -) RTP statistics
are persented, with 6,2% packets loss.

When DISabling protocol "Mpeg PES" ,  0% Packet loss is presented.

The "lost packets" are related to "Malformed Packets" when "Mpeg PES" encoding
is enabled. 

Althouh i doubt if the mpeg pes is really "malformed" (will investigate this
later), my opinonin is that RTP statistics, must NOT be depended on lower level
decoding !

All Packets on RTP level are available, whith correct seq.numbers, so
packetloss of 6% when enabling lower level protocol, seems very silly, and
incorrect.
