IEE 1394 / FireWire (Apple) / i.LINK (Sony) has been a standard connection to transfer native DV and HDV video files to Lin/Win/Apple computers.

FireWire DV/HDV recording should still work via dvgrab, vlc, guvcview, OBS and ffmpeg etc., or directly via some NLE systems.
The basic dvgrab tool is still valid on Linux and was mentioned in the Cin-CV wiki sect. 19.2

ffmpeg enabled FireWire DV/HDV input device using libiec61883 (Streamcopy) seems also interesting.

On my Leap 15.4 or Tumbleweed, ffmpeg-5 is seemingly not compiled with --enable-libiec61883.

Is possibly ffmpeg available with enabled libiec61883 via Cin-GG?

I had a look into the Cin-GG manual chpt 13 "Capturing and Recording Media", but could not see Firewire media transfer was mentioned. However, in the Appendice section B.2 Configuration Features, Optional Packages is found:

--with-firewire use firewire (auto)
--with-dv use dv (auto)

Does this mean that Firewire/dv capture already is supported or optional can be configured?
