Hi,>Could I continue decoding H264 with wireshark the rest of the data ([Not decoded yet])?Shure but it might not be easy as some decoding depends on parameters previously received if I remember correctly.>I have also observed the data is given in hexadecimal. I read the H264 bitstream is coded with exponential golomb but I dont really know if its true.
> Does wireshark the conversion?
YesRegardsAnders

Subject: Re: [Wireshark-users] h.264 with WiresharkThanks anders!!
It works, but i can only get the first data:
H.264
FU identifier
0... .... = F bit: No bit errors or other syntax violations
.10. .... = Nal_ref_idc (NRI): 2
...1 1100 = Type: FU-A (28)
FU Header
1... .... = Start bit: the first packet of FU-A picture
.0.. .... = End bit: Not the last packet of FU-A picture
..0. .... = Forbidden bit: 0
...0 0001 = Nal_unit_type: Coded slice of a non-IDR picture (1)
H264 bitstream
1... .... = first_mb_in_slice: 0
.001 10.. = slice_type: P (P slice) (5)
.... ..1. = pic_parameter_set_id: 0
[Not decoded yet]
Could I continue decoding H264 with wireshark the rest of the data ([Not decoded yet])?
I have also observed the data is given in hexadecimal. I read the H264 bitstream is coded with exponential golomb but I dont really know if its true. Does wireshark the conversion?
Thanks for your help!!!

Subject: [Wireshark-users] h.264 with WiresharkHello,
I wanna decode H.264, i read the thread http://www.mail-archive.com/wireshark-users@xxxxxxxxxxxxx/msg03835.html but i wasnt able to decode h264 (wireshark à preferences à H.264 à dynamic payload 125), I use Development Release 1.3.2
I get a RTP+H264 stream:
10.. .... = Version: RFC 1889 Version (2)
0... .... = Marker: False
..0. .... = Padding: False
...0 .... = Extension: False
.... 0000 = Contributing source identifiers count: 0
Payload type: DynamicRTP-Type-96 (96)
Sequence number: 23252
Timestamp: 868956473
Synchronization Source identifier: 0xcbd5dcba (3419790522)
Payload: 7C05FFE5F98EB9B5AED78E67EB3C2A941606A7CCD179710B...
Is it possible to decode H.264 by decoding the RTP payload? How?
Thanks for your help!!
