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?
http://www.ffmpeg.org/ffmpeg-devices.html#iec61883
http://underpop.online.fr/f/ffmpeg/help/iec61883.htm.gz
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?
in preferences -> recording tab there must be source named IEC 61883.
To cross-check I translate back from my local Norwegian version to
English:
Settings | Settings | Preferences window:
Video In / Record driver
In the dropdown menu there are available both
* DV 1394
* IEC 61883
As reference also the following from Cin-CV's wiki and from Raffael's
Howto (Cinelerra for Grandma):

Firewire
Firewire is the fastest way to download material into your system.
Unless you will be importing your media from a CD, any other
pre-captured format or use an analog video grabber, you will need
firewire on your system.
DV cameras
There is an large variety of DV cameras that can be used with
Cinelerra. Almost any camera that can connect using firewire will work.
Be sure to set the appropriate parameters on the video grabbing system
to match your particular camera.

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:
