dvgrab

[francpal]

Hi! I work from the Linux bash command with dvgrab commands.. How can I capture videos in .m2t selecting start and end? For example if I have a video during 50 minutes and I want capture only from 00:15:00 to 00:43:00 how can I do it?

Another question: is possible use dvgrab and ffmpeg together? (dvgrab for capture and ffmpeg for encode)

thanks

I think the linux forum section is better for this. Moving you.

Nope, I have no idea how to use dvgrab.

A search gave me:

ever thought about compiling ffmpeg with firewire support and simply use just ffmpeg? (see: http://www.ffmpeg.org/ffmpeg-devices.html#iec61883)
Other than that using named pipes might work,... (never used dvgrab)

Hello. I'm interested in the dvgrab program for Windows - does anyone have one?

1. posting in a 12-year-old post: bad behavior (would have been better to open a new post and reference to this one)
2. afaik https://github.com/ddennedy/dvgrab is Linux only.
3. Why not use https://www.videohelp.com/software/WinDV on Windows?

Hello. I'm interested in the dvgrab program for Windows - does anyone have one?

Also you should try the (now free!) ScenalyzerLive

I need a program dvgrab to combine a powershell script and a MiniDV camcorder, to control the camera (playback, switch to forward, backward, etc.), I tried via the MINI USB cable in the program ScenalyzerLive(so far the only program that can copy data correctly) but it makes the camera a little buggy, and the camcorder freezes.

Maybe there is, for example, a Python script that can control a MiniDV camcorder, that is, with commands, and can store information from it?

Your problem is that FireWire-to-USB cables don't work.

[nadya86]

Maybe someone didn't read carefully or the translator didn't translate accurately. The camcorder has two connectors: FireWire (my computer doesn't have that connector) and USB mini. And I connect the camcorder via USB mini to the computer through the ScenalyzerLive program and the camera works, and I can control it. But the program has a bad effect on the camcorder, and sometimes the camcorder itself freezes on one frame. I hope you understand!

True, but some Panasonic camcorders have DV transfer via USB which works very well.

@Nadya86, what is the make and model number of your camcorder?

[nadya86]

Panasonic NV-GS500

[Alwyn]

You do have DV over USB. Given Scenalyzer is "sort of" making contact with your GS500, try checking and/or changing your Windows Firewire drivers. I have a spiel on it on my website here.

[nadya86]

I repeat once again that I'm trying to write a PowerShell script that will control a video camera via USB mini, I've already done what I can to copy data from the video camera to the computer, but I don't know how to control it: play, fast forward, rewind - yet, that's why I wrote here that maybe someone has their own written program or script.

My point was that if you have firewire set up correctly in Windows, Scenalyzer will give you full control over your camcorder.

If you want to programmatically run your capture flow:
- Switch to linux (dual boot) for capture to properly install DV grab
- use WSL + dvgrab + bash (or powershell on linux if you insist on psh)
- (recommended) Use DV rescue CLI, that is a modern tool, it has a native windows binary and as the name implies, is a CLI version so can be invoked from whatever scripting language you want to use: https://old.mediaarea.net/download/snapshots/binary/dvrescue/20260502/
- use some tool that can automate the clicks for you with whatever tool you're using (worst solution)

[nadya86]

My PowerShell script for Windows can capture a MiniDV stream and save it to a file. No problem there! I want to do video camera curation via a script - you know? If anyone has some kind of program like dvgrab but for Windows?

@nadya86, I just gave you one if you read my reply!
