Hanssen via Cin <[email protected]>: 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 librariesCould 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
----------- I looked up some of the older discussion about dvgrab on CinCVS/Skolelinux mailing list and the referenced manual wiki: https://www.mail-archive.com/[email protected]/msg13022.html https://www.mail-archive.com/[email protected]/msg06183.html http://cinelerra-cv.wikidot.com/cincv-manual-en:tips#26 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: https://github.com/cinelerra-cv-team/cinelerra-cv/commit/0ff51f4c53e17ff33701e8cc1096de33a87313b9Other NLE references, Premiere Pro and Vegas respectively https://helpx.adobe.com/no/premiere-pro/using/capturing-dv-or-hdv-video.html https://www.vegascreativesoftware.info/us/support/article/capturing-video-from-a-sony-camcorder--222/ Terje J.
