Wireshark · Wireshark-dev: [Wireshark-dev] Extcap limitations?

[ws <ws@xxxxxxx>]

Hi all,

I have had a look at extcap in wireshark, it looks like dumpcap is being 
called to read from the FIFO which the excap binary writes to.

However, dumpcap is only able to read libpcap formats (not even pcapng) 
when reading from a pipe.

Shouldn't extcap support any arbitrary file format and/or determine the 
format on the fly by either specifying one in the extcap binary or via 
calling something like cf_open()?

Thanks and regards,
ws
