thanks for your answers but a real need to know the PT value a really need it
anyway can someone explain me how can i get the delay, jitter, packet loss with the RTCP capture

here is a part of my capture a found probleme to attach files

44    51.562500    161.106.176.16    10.24.1.179    RTP    PT=Unknown (96), SSRC=0x2C7008, Seq=0, Time=0, Mark     srvc_registry
45    51.562500    161.106.176.16    10.24.1.179    RTP    PT=Unknown (97), SSRC=0x12C7008, Seq=0, Time=0     srvc_registry
46    51.796875    161.106.176.16    10.24.1.179    RTP    PT=Unknown (96), SSRC=0x2C7008, Seq=1, Time=1024, Mark     srvc_registry
47    52.000000    161.106.176.16    10.24.1.179    RTP    PT=Unknown (97), SSRC=0x12C7008, Seq=1, Time=0 [Malformed Packet]    srvc_registry

Hi,
There is no trace file attatched???
Jitter analysis does not work well for video see bugs
 
And the setup info for the RTP stream must be in the trace as well to know what the PT is. Delay and packet loss should be possible to determine
without knowing the PT. If there is RTCP packets those helps as well.

Anders

Hi,
i mean in the column info I can see        44    51.562500    161.106.176.16    10.24.1.179    RTP    PT=Unknown (96), SSRC=0x2C7008, Seq=0, Time=0, Mark     srvc_registry
and when i read the mailing list it seem to be a problem my aim is to calculate the delay, jitter, packet lost ....  when the devise move away from the access point is there any matter with this PT= Unknown(96)
you can find the capture attached
best regards

Hi,
Decode in what sense? to see fields in the MPEG4 stream? which type of MPEG4 ( Mime type/RFC/proprietarry?) do you have a small sample trace including the setup information ( SDP)?

Anders

hi everybody, hi Fabiana moreno

I followed all your thread you posted in this mailing list and i am facing to the same problem i try to capture streaming file with wireshark (i have to study the QOS of HD profile over wireless  network ) and it can't  decode  the MPEG4 stream.
I don't found the solution in this mailing list  so can you tell me how do your resolve this  matter.

every help is welcome
