Hi,

I have this pcap where I capture HTTP2 messages for a connection that is already established when I start the tcpdump.

In the wireshark, the data and headers are not decoded. Is there any way to have wireshark decode it, even if the pcap is missing the connection setup?

Thanks Octavian.

Hi, Not without code changes. I have suggested these cahnges to the support library used to decode http2 https://github.com/nghttp2/nghttp2/pu...

Hi Anders, meanwhile is there a way for me to get the http2 path, from an existing packet, not decoded in a pcap file?

for example:

Hi, The development version of wireshsark has a solution implemented which fixes most problems.
