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
* http://cinelerra-cv.wikidot.com/cincv-manual-en:capturing-media#5
* 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?
it was not tested in ages .....
guess try to install all -dev version of libraries and look at
output of cingg's configure .... then connect device and try to
set capture device to iec* ....
I guess that's not just for me ;) but will try dvgrab again
(tested it once several years ago), when my camcorder is back from
service.
The reason is my 10 years old FireWire based DV/HDV recorder
seemingly is dead.
well, you can look if appimage version of cingg was compiled with
those libraries
Could you possibly outline how to do it?

I looked up some of the older discussion about dvgrab on
CinCVS/Skolelinux mailing list and the referenced manual wiki:

21.12.2 Grabbing HDV from camcorder
There is no perfect solution so far. One possibility is to run the
test-mpeg2 command available with the sources of *libiec61883*. Use
this syntax:
|test-mpeg2 > hdv_tape.mpeg|
and press *Play* on the camcorder. You should not run any heavy
resources consuming task on your computer since the lack of caching
in test-mpeg2 causes frame drops.
New version of dvgrab seems to support HDV. Minimal example:
Syntax:
|dvgrab -format mpeg2 myclip|
, but I am guessing (from bug
https://www.cinelerra-gg.org/bugtracker/view.php?id=590 ) you might
run into troubles trying to record exactly HDV stream - because it is
not DV video, but mpeg2. There is code in DVB input module for dealing
with this, but it probably must be wired to DV /firewire module, or
something like this should be used in ffmpeg.C for pre-decoding
compressed buffer:
