Hi Terje,
Currently my HDV camcorder is on service, so I ask: Is it possible to
transfer/grab HDV files via Firewire to ffmpeg? (I have already
libiec61883, libraw1394, libavc1394 installed on my Leap). If so, a
command example or guide to start with would be welcome.
I still occasionally transfer videos from miniDV/Digital8/Video8 tapes
to PC. I use the "dvgrab" tool for that. It's a simple command-line tool
and will save the video without any re-encoding. In the second step you
can transcode the files with ffmpeg to any format you like (also you
might want to consider some advanced deinterlacing/denoising in between
depending on your source material and it's intended purpose).
I never tried HDV, but it does support HDV as well. It's in the standard
Ubuntu repository, no need to compile it yourself, not sure about other
distributions.
The tricky part is the FireWire interface: Not all FireWire chipsets
support cameras flawlessly, my first tries with an onboard-FireWire
interface resulted in a lot of corrupted and dropped frames.
I got myself an ExpressCard with a VIA VT6315 chipset I'm using in my
old notebook, works perfect.
I tried a PCI-e card with the same chip in my PC, no luck, entire system
crashes every 10 minutes. I assume old PCI-e devices are not completely
compatible with new PCs.
Best regards
Stefan
I tested dvgrab once - it must have been about 15 years ago when my FX7
HDV camcorder was new.
Later on I thougt it was gone (like Kino).
Yes, dvgrab is still available and packaged for openSUSE Leap 15.4, and
I just installed it.
When Dave mentioned firewire and ffmpeg, and I googled this document
"FireWire DV/HDV input device using libiec61883"
http://underpop.online.fr/f/ffmpeg/help/iec61883.htm.gz
I got the impression that this had replaced the need for dvgrab(?)
Thanks,
Terje
