There are a number of systemd* binary packages
Is that the reason for the many systemd references in the file-system?

Thanks Camtaf.
I'm already familiar with TestDrive and find it completely reliable. I've used it in anger 3 times now (on a FAT32 hdd) and it is odd but works fine - I'm comfortable using a TUI since I started with MSDOS & progressed to BASH.
If TestDisk works with a mirror from his Windows utility then the HDD will likely be redundant, but I'm also trying to think ahead for his purposes as well as mine.

Look into Ventoj.
Thanks rolfie. I see these:
ventoy.net
(latest: 2023/10/06; I see NTFS supported there)github.com/ventoy/Ventoy
(I see Devuan supported there)
My final desire here is to know if legacy + UEFI are supported simultaneously. This one looks damn good.

Thanks for replying.
I cannot find Devuan on that page. However, it is an interesting option, even if it means that I have yet another new app to learn from scratch.

I'm anticipating a possible need for a USB-connected HDD to be able to boot on a large-range of unknown-OS systems (in BIOS switch to USB-boot & then boot from the portable HDD). However, it will NOT be me doing the boot, but rather another person. That person is well-experienced in computing, but not in Linux.
There are two possible operations that I would want to make easy for them:
Use DD to obtain a mirror of a local-or-remote HDD
Use TestDisk to recover deleted files from the mirror onto the portable HDD
The other person is experienced in using some Windows software in making a mirror (he told me what it was but it was unfamiliar to me & I cannot recall it's name), so #1 may not be necessary. Obviously, I can also do #2 once the mirror is obtained (although any thoughts on the best means to set that up with the HDD would also be appreciated).
I've recently obtained a WD 4TB portable HDD (it is called "My Passport") and am wondering which ISO would be best to install as the default bootup. If it could be setup to dual-boot with Windows that would be perfect for the other guy. The HDD is pre-formatted with modern NTFS, and hopefully I can partition that with GParted (possibly with FAT32 to allow wide-usage?). I'm 20 years out of date with Windows & would appreciate any skilled suggestions of how to set it up (Live Daedalus?).
To pre-answer enquiries, this would be in connection with a soon-to-start civil trial and a possible need to recover deleted files from a computer in connection with that. I have zero idea of what the computer system would be, not even it is local or remote. Obviously, a court order would be required to obtain the mirror. It would also be another useful tool for the other guy in his work (he makes his living from his computer expertise).
My thoughts are not fully-formed with this yet, so the above is a bit sketchy, but I'm behind in my timings, have zero experience with the Live ISOs & need to do this very soon.
Any help much appreciated. TIA.

It unnecessarily increases server space, load & network travel-times. Thread viewers other than you hate it & are forced to plough through acres of duplicate content.

Splendid. Thankyou.
As I said before, I've never used (nor want to use) Bluetooth. However, you now know that your hardware is accessible & ready.
I'm sure that there are guides on the 'net for howto use Bluetooth under Devuan/Debian (or write one yourself).

@hunter0one:
Have you tried Ralph's advice?
(in a terminal):
Switch to the root user (which means su -; enter the root password, not sudo)
lsusb will show all connected usb devices
enable write access for the other user on the EasyCap device: chmod o+w /dev/bus/usb/001/015
Without rebooting, try qv4l2 & see if now it will allow you to see your vhs screen in the window.
I very much want to work with you to get my script to work with other devices (such as yours) & get a good result to allow folks to stream it to disc.
#170 Re: Desktop and Multimedia » Input/output error with EasyCap capture card on VLC and OBS » 2023-09-14 18:06:08
For devices you get c==character (bytes) or b==block (hdd, etc).
That is a root.root user.group & you will need to use sudo if you wish it to be changed.
#171 Re: Desktop and Multimedia » Input/output error with EasyCap capture card on VLC and OBS » 2023-09-13 21:57:59
It seems that there's only a few bits of capture hardware that are capable of doing the job. Sorry that yours is not one of them.
#172 Re: Desktop and Multimedia » Input/output error with EasyCap capture card on VLC and OBS » 2023-09-13 09:02:34
For some reason the capture image format and image size can't be changed in QV4L2
That is academic. ffmpeg is near miraculous; it will change a video from any format to any other format. My script has the wrong fps AND pixel dimensions for your supply (the script is using "-s 720x576 -r 25" which was correct for my VHS signal, but not yours) but ffmpeg would happily make that change.
The issue for you is hardware & region (as best as I can tell).
v4l2-ctl --all is giving a full, error-free readout of the input video device.
arecord -l is accurately recording the audio hardware as 'hw:2,0' ("card: 2, subdevice: 0")
Only region remains (for me, the picture only appeared in the V4L2 screen when I changed the region from the default NTSC to PAL; ymmv).
If you cannot find a combo that works then the answer may be that zero signal is arriving at the input. Do you have a broken wire?
#173 Re: Desktop and Multimedia » Input/output error with EasyCap capture card on VLC and OBS » 2023-09-13 00:07:32
You seem to have the correct hardware devices. In your position I would change to the root user & try again. If you cannot get the picture to appear in the V4L2 screen then it is bad.
Try all the various options with the V4L2 utility. It took me a while to find the correct mix before I got the video to appear. However, if you cannot get it to appear then throw the hardware in the bin & try something else.
Good luck.
PS
From the v4l2-ctl --all output, the fps in the script should be switched from 25 to 30. However, do not touch anything until you get V4L2 to work. Only if it will work there will the script work (using the same setup options).
13 Sep update: made clear re: fps I was referring to the script, not V4L2.
#174 Re: Desktop and Multimedia » Input/output error with EasyCap capture card on VLC and OBS » 2023-09-12 23:23:24
I've made the ffmpeg-recommended fix (search for "vsync is deprecated") to the bash-file & uploaded it. No checks, but the change is most modest & should work.
#175 Re: Desktop and Multimedia » Input/output error with EasyCap capture card on VLC and OBS » 2023-09-12 22:47:55
It is telling you there are errors on both the VIDEO_DEVICE=/dev/video0 + AUDIO_DEVICE=hw:2,0. It seems that the hardware that you are specifying (which happen to also be the defaults embedded in the script) are wrong. No point in going any further until those are checked. Either the precise devices are wrong or your user is wrong.
What are the results of v4l2-ctl --all + arecord -l or arecord -L or cat /proc/asound/cards?
I see that you were using the qv4l2 tool (QT v4l2 test utility). Very sensible - I used that as well (mostly to check REGION). However, if you cannot get the screen to appear in that utility then the bash-file will never work. The idea is to try different setup options until a picture appears. You can then supply the different options appropriately. Whatever options allow the V4L screen to show your VHS/Camera/whatever are the precise options to use with the bash-script.
Pay attention to your user. Your ls -l results show that you will have permission errors unless you go root. Or try the advice in the Wiki link: sudo chmod a+r /dev/video0. I'm pretty sure that that is why you are getting the 'input/output error'.
