   Good advice.

   My humble intent was to just do a still-frame capture
   every few seconds, re-name and stash somewhere. Easy
   with lots of webcam apps, but not with ......

   I think I *can* do that basic trick now. But do I
   want to ??? Better off with little web-cams. Look
   for "Spinel" ... they USED to have a micro-boxed
   board, but of late only bare boards. Easy to use
   and cope with and highly sensitive. DID fit one of
   those microboxes AND a Pi3 into a little weatherproof
   box ... it's now on a screen porch. IR sensitive
   24/7 ... I *like* the weird colors ! Also made a
   sunrise/sunset daemon that adjusts the video params
   at the right time every day. Similar on several units.

   For three out of four - it DIDN'T see the cams reliably.
   ONE registered as "there", but you couldn't get any video
   from it no matter what. Kinda wasted a lot of money ...

   Yea, tried that today - UDP and TCP. However VLC could not
   cope with that. It WAS getting data, but NO visual regardless.

   External boxes, maybe tomorrow's project. Gotta
   keep the brain busy. Hey, it's 2:30 AM now, been
   busy for a LONG time :-)

   FFMPEG is the best documented and most capable. However,
   as noted in this group, I've also had lots of weird
   problems with it. Basically I have to take those UDP/TCP
   h264 streams and create jpg and/or mjpeg. Have another
   app that captures RTSP and, correctly, creates a 1-FPS
   movie. The "rpi-vid" whatever can't actually cope with
   creating a proper 1-FPS video.

   "Correctly" means it doesn't have 29 identical frames
   every second - ergo I can create very compact vids
   WITH SOUND from one of my front-door prox IP cams.
   Ffmpeg CAN do wonders IF you can find the exact
   combo of params. Took awhile.

   ALL I've seen is 'rpi-still'/'rpi-jpeg'/'rpi-vid'. Some
   sites talk about 'libcamera' stuff - but there's nada.
   What is Where ... seems to move back and forth between
   distro versions, often.

   Anyway, will probably abandon the ribbon-cable cameras
   because they're SUCH a pain. Now gotta find USB connectors
   that aren't two+ inches long, will fit in a tiny box.
   What's the point in a little board if it has BIG connectors
   sticking out in every direction ???

   One of the most useful video pgms is 'motion'. Alas they
   changed the config files considerably of late, so beware
   of older doc. Easily creates mjpeg streams and CAN do
   movie segments, though not with as much control as a
   custom app. Create most ALL my security cam stuff
   using 'motion' as the base.

   Hey, keeps the old brain busy !!! Now almost 3am ...
   STILL messing with this stuff. (also it's still
   over 80F ... my A/C is old and clunky, BIG $$$ to
   replace all that ! Electricians, permits maybe,
   yikes !!!)

   Note my house is early 1950s ... a pill-box that's
   wiring UN-friendly. Will need an extension box for
   100 amps, new conduit/wires, what a PAIN ! And in
   the meanwhile ... COOK. I have some fans, but there
   are limits. As you get older there's LESS tolerance
   for cold and heat alas. Hawaii would be nice, but
   insanely expensive (and Obama is there !).

   But all that's a different "survival" theme ...

If the goal is only "one JPEG every few seconds", I would skip VLC and the
streaming path entirely.  Let the camera program write stills directly.

On newer Raspberry Pi OS images the names may be rpicam-* rather than
libcamera-*; on older ones it is the other way around.  So check both:

    command -v rpicam-still libcamera-still

The usual package is the Raspberry Pi camera apps package, called rpicam-apps on
newer installs and libcamera-apps on some older ones.

For a simple timed capture, the shape is roughly:

    rpicam-still -n -t 0 --timelapse 5000 -o frame%06d.jpg

or, on older installs:

    libcamera-still -n -t 0 --timelapse 5000 -o frame%06d.jpg

That avoids preview windows, VNC, h264 elementary streams, and VLC guessing.
Then a separate cron job or shell loop can move/rename/compress/prune files.

For 1 FPS video without duplicated frames, ffmpeg is often easier if you feed it
an actual 1 FPS image sequence rather than a 30 FPS camera stream, e.g. capture
JPEGs first, then encode the sequence later.  That is less elegant, but a lot
more predictable on small Pis.

   A very simple Python daemon can do that nicely.

   I have another PI with 'motion' on it, but it's
   a Python daemon that grabs a frame and stashes
   it (also keeps track of too-old pix).

   Yep, the first one works on my Pi4, most recent distro.
   Haven't used the "timelapse" yet however. Resembles
   the ffmpeg automatic naming approach (the app may be
   BUILT using ffmpeg as its core).

   Still a bit vague on where/how the ribbon-cable cams
   deliver stuff. "Network" port - "localhost:1234" ???
   Something weirder ??? Gotta check some more.

   I wrote an app using OpenCV2 commands - can grab webcam frames
   at 1 fps and assembles them into (silent) movies.

   Ffmpeg ... had some good experiences and a few bad. The doc
   seems all over the place. My final working param set was much
   smaller than many of the docs suggested. Do have it making
   RTSP movies at 1-fps, resized, but with continuous sound.
   Works well EXCEPT kinda in the middle of the day - very odd.
   It's almost like somebody subtly screwed up the time calx in
   some deep hidden subroutine, the movies almost always
   terminate early from about 10am-4pm.

   The trick with movies is keeping the SIZE down. Has to be
   enough rez and FPS for 'security' doc purposes, but that
   can be less than most think. 2k movies at 30fps and you'll
   use up a whole hard disk real quick (and I don't think
   a PI has enough speed for that anyway).

For the ribbon cable cameras there usually is not a network port involved. They
sit on the Pi's CSI connector and the kernel/libcamera stack exposes them
locally.  So the first sanity check I would do is just:

    rpicam-hello --list-cameras

or, on older installs:

    libcamera-hello --list-cameras

If that sees the module, rpicam-still/rpicam-vid talk to it directly.  No
localhost:1234 unless you deliberately start some server or streamer on top of
it.  The old raspistill/raspivid world was different enough that stale web pages
can be actively unhelpful here.

For USB webcams the path is more like /dev/video*, and then v4l2-ctl is useful:

    v4l2-ctl --list-devices
    v4l2-ctl -d /dev/video0 --list-formats-ext

For CSI/libcamera cameras, the rpicam/libcamera tools are the better first
probe.

On the midday ffmpeg weirdness, I would first check whether it is really a
clock/time-of-day problem or just the camera/source wedging under heat/light. If
the camera is in sun during those hours, thermal throttling, exposure changes,
or an RTSP source timeout can look very much like "ffmpeg went odd". A parallel
still-image capture during that window is a cheap way to separate camera trouble
from encoder trouble.

Check that bet one winter when the ice storms pull down the mains 
cables powering your local copper exchange, and the snow is deep enough 
that the fuel trucks can't get to the exchange before its backup 
generators consume the diesel in their tanks.

The copper *will* also stop working then as well.

It only appears to keep working because there were several layers of 
redundancy backed in by the regulations.

But those regulations are being sidelined now.  Without those 
regulations keeping the companies honest, the old POTS that "just kept 
working" almost all the time will become just as flakey and offline at 
the slightest provocation as the other options.

A *lot* of expense was spent to make the old copper POTS just "keep 
working", not a bit of it "just working" was because it was "copper".  
It was all because the companies operating it were kept whipped into 
shape by the regulators and forced to pay for the upkeep needed.

If you applied the identical regulations to fiber, it too would (and 
could) be just as much a "it KEEPS WORKING" system as the old copper 
POTS system was.  All the fiber would need to be all but identical is 
for a pair of power conductors (yes copper wires, since glass happens 
to be an electrical insulator) to be run along with each bundle, and 
for the demarc terminals in each home (plus one of the phone handsets) 
to be powered from the fiber bundle power conductors.

The magic that made copper POTS just "keep working" was the strict 
regulations surrounding it, not the fact that it was copper.

That would not happen.

What could happen is mandating the router or ONT have a battery backup 
included, or at least optional. As simple as installing a bunch of AA 
batteries.

Agreed.  I highly doubt such would ever occur to the regulators as 
well.  My point is, it would be /possible/ for the fiber bundle to 
carry a single copper pair used only to provide the small power 
necessary to power the end point just like old style analog POTS phones 
were powered by the line from the switch.

Yep, that's already what Verizon does with their FIOS service.  One 
gets either a lead acid battery (UPS style battery) that will power the 
ONT for "some time" on a power fail, or one gets a rather large box 
that holds something like 12 D sized alkaline cell batteries as the 
"backup power" should mains be out.  I'm not sure if the different 
types arrive based on price level purchased, or just on "previously, 
they privided this, now they provide that".

Thing is, they would have to power the ONT or the router, and do so for 
all customers the full time, even if they are not using their phones 
actively at the moment. That is no small power, it can be 2..3 amps at 
12 volts per client (based on the ratings of the power wall wart of my 
router.

That is not a small power. Orders of magnitude over what POTS needs: all 
houses not actively using the phone draw no power at all.

The wall wart rating is a ceiling, not the normal draw, but the basic problem is
still real.

A plain POTS set is almost unfairly cheap to keep alive. On-hook, it is
basically a supervised loop drawing almost nothing at the subscriber end; off-
hook it is tens of milliamps from a central battery plant that was built,
maintained, and regulated around that job.

An ONT plus router is a different animal. Even if the ONT idles well below its
adapter rating, it is still active electronics at every customer site. If the
service needs voice, routing, WiFi, or an ATA alive during an outage, then the
backup problem has moved from one hardened central office to a pile of little
boxes in houses, closets, and garages.

That is why the old system felt magic. It was not the copper. It was the
engineering assumption that the network had to power the endpoint and keep doing
so when the customer's mains failed. Fiber can be made reliable too, but only if
the same requirement is written down and paid for instead of being waved away as
an optional battery accessory.

On hook, on an old phone I think it is a capacitor in series with a bell 
ringer coil; there should be a 48 DC nominal volts and no current. To 
ring, the exchange sends an AC voltage of around 60 volts. Being AC it 
passes the capacitor.

On a modern POTs terminal, there are active electronics, so there may be 
a small current draw while on hook

   Um, USA, I think the 'ring' is closer
   to 90 volts.

   But, overall, that's How It Works. Simple
   yet functional.

You /may/ be confusing peak with RMS AC voltage.  The RMS voltage 
applied for ring is about 60V RMS.  Which works out to an 84.9v peak AC 
sine wave, which is likely were your "closer to 90 volts" may have come 
from.

Yep, exactly.  The original engineering assumption was the central 
plant had to power the end points.  And that was made, at the time, not 
because anyone thought about "emergency services calls" (such a concept 
simply did not exist before there was a widespread telephone network 
installed).  The original design parameter of "central office powers 
the end points" was made because the phone network was being installed 
during the same time frame that mains electricity was first being 
installed as well.  There was no guarantee that homes being wired for 
phones would have mains power yet, therefore the need for the phones to 
be powered from the central plant.

Yep, it would add expense.  And the companies would cry-baby enough 
that they would end up wanting to charge $500/month or more for what 
they now charge $65/month if they were forced to make it equally as 
reliable.

Don't look at the label on the wart as the consumption of the device.  
The wart's labels are what it is rated to output without lighting your 
house on fire.  If you measure the actual draw of the connected 
devices, you'll often find it is much less than the wart's max 2..3 
amps.  Often substantially less.

In any case, that is also fixable.  Run the power conductors at a 
higher voltage (48v -- the POE voltage) or even whatever your mains 
voltage is (220 in Spain?).  Then the current in the big cable is much 
reduced, even with every end point 'running' and drawing power.  It can 
be done, but it is also very much a not likely to be done thing as 
well.

Of course this would likely mean fewer "end points" on each arm from 
the local switch, as no matter how high one runs the voltage on the 
power pair, there is a limit of how many demarc's it can power at once.

Alternately, each "fiber line" could include a pair of power conductors 
to power that one end-point (again likely running a higher voltage to 
cover for resistive losses in the long wires).

But also, just an 'imagined possibility'.  No regulator today would 
think of trying to impose any such requirement anyway.

For a home setup the useful first step is to measure the real load, not size
from the wall-wart label.  A cheap plug-in wattmeter on the AC side, or an
inline DC meter if the router/ONT uses a barrel connector, will usually show a
much smaller steady draw than the adapter's maximum rating.

If the goal is keeping voice or basic connectivity alive through short power
cuts, a small DC UPS or a modest AC UPS sized from that measured load is a lot
simpler than trying to make the access network provide line power.  Then check
whether the ONT, router and any ATA/DECT base all need backup; missing one box
in that chain is the usual surprise.

I have looked at small DC-UPS designed precisely to power the router, 
and they are designed for 3A. But one of them just has two AAA cells. 
That's damn not enough.

Two AAA cells will provide 3A, for a rather short length of time....

Yeah, there's not enough energy in two AAA cells to power a modern 
router for longer than very brief intervals, unless that same router is 
very minimal power draw itself..

There is something else. It would be a tree network of DC cables going 
out from a central node. Two thick cables going out, perhaps 48V DC, 
then branching at each home (and fuses). At least part of the network 
would be thick cables. Which means, some people would try to steal them.

Is it true some people even try to steal the kind of bare wiring that is
used carry 25 kV 50 Hz?

They steal the live catenary from the railway... Sometimes someone dies. 
The distribution wires, I have not heard of it. Too high?

We would need harsher laws to protect the railways.
