Confusing problem. Netflix works. Kanopy and Hoopla through
my library don't. Tried Win7 and Win10, Firefox and Chromium.
So, four different configurations.
The sites are fine, but the video doesn't start. DRM enabled.
No clue of what could be wrong except this in Chromium:
"Unsupported keySystem or supportedConfigurations"
But I can't find anything informative about that error.

They mention a WideVine problem here, as a potential source.
I would expect at least a Netflix, would use something as
powerful as WideVine. One of the reasons nothing works on
my Seamonkey browser, is no WideVine module or plugin. It means
I can't view videos on my local TV station websites!

Firefox and Chrome might have WideVine. I don't know
if Chromium has WideVine. And WideVine is an example,
because you would expect it to use crypto for its
DRM management (handcuffs).
if the server handcuffs API version got bumped up, it
could be a crude way of saying to you "use the very latest
browser version to view this site" :-) I think you have
seen this behavior before. Like every morning when you get up.
This is why I keep a couple configurations. My "comfort"
configuration, with blockers and shit. And my
"fully compliant Hollywood ready" configuration,
approved by Mother Theresa herself. I test on the
blessed version, when the Comfort setup breaks, just
to see if anything can work. But it does not mean
I use the fully-compliant version all day long. Just
long enough for a plumbing test.

I'm fairly certain Netflix uses Widevine. I don't know of
any alternative. Both FF and Chromium have it included.
And I have the latest version of each on a fresh Win10
install. I removed my HOSTS file, disabled NoScript....
I can't think of anything else to try. And on top of that,
Hoopla and Kanopy were working fine until recently. I
visited the library to ask them. The librarian started the
movie I'd tried to watch, on her cellphone, with no trouble.
All attempts have been on a Dell XPS 625 piping to a TV
via HDMI, so that's one thing I haven't tested. But I can't
think of any factor there that could be a problem. The Dell
supports Win10. Netflix works fine on FF, on either 7 or
10. 7 has v. 115. No problem. All of this is on the Dell.

Kanopy is a pay-per-view. Which means the wrapper would have
to be secure, and if your LCD monitor was 1920x1080 or larger,
it would need HDCP (end-to-end encryption to prevent
copying from places like the video card memory if using
the video card CODEC for playback). There is nothing in the
available info, suggesting a root cause. And your equipment is
modern enough to have seamless HDCP.

OK, it's Widevine. Is it worth rolling back the version of this ? Dunno.
https://forum.videohelp.com/threads/401113-Help-downloading-MPD-from-Kanopy
widevinecdm.dll and widevinecdm.dll.sig
I am unable to find such a thing as a Kanopy test strip, just to verify
the plumbing works. Any Kanopy entries I find, ask for library card and PIN.
"Troubleshooting DRM"
https://help.kanopy.com/en-us/4145.htm
One piece that can break is the MPD (MPEG DASH manifest (dynamic adaptive streaming over HTTP)).
It's much more likely that the Widevine broke, or your screen
resolution has changed since the last time it was working.
Another clue here that I'm hoping might mean something.
I looked it up and so far haven't found anything useful.
Chromium on Windows at Kanopy shows the mysterious
message "Unsupported keySystem or supportedConfigurations".
I tried it on my Raspberry Pi, which also runs Netflix fine,
and I get a different message in Chromium when I try to start
the video. It says the video is encrypted and it doesn't have the
decryption keys.
How could all the latest browsers be missing the keys
for streaming at some sites? Kanopy claims to still support
browsers. I've never heard of updating decryption keys.
Any idea how that works?

Doesn't help, anyway. This seems very fishy. I went to the library.
They were very helpful but didn't know anything. One librarian
loaded the movie I'd wanted on her cellphone and it started fine.
That makes me wonder whether maybe these companies have
stopped supporting browsers for security reasons. Yet a browser
or a limited selection of TVs is the only option they list for
Desktop. Perhaps they've somehow misidentified me as being
on a mobile computer? But I tried 2 computers, 3 separate
Windows installs, 2 browsers on each, plus the RPi4. The only
commonality at this point seems to be my IP address. Yet both
Kanopy and Hoopla let me log in, browse, select a video. The
video just doesn't start.
I did have an interesting experience with AI, though. I wrote
to Kanopy and got a generic resonse that told me to describe
the problem, which I'd already done. I wrote back. "Eustacia"
answered with a list of troubleshooting tips. I wrote back and
said it looks like no human is actually reading my emails, but I'm
writing back just in case. I reiterated the details.
Eustacia then wrote back with an interesting response, saying
that, yes, actually, there are no humans. There's just an
auto-response providing standard troubleshooting tips. But if
I write enough times then the computer will forward it to the
developers. Was 3 times enough? I don't know.
So no one is minding the store. It's an automated operation.
But I thought it was interesting that my wording seemed to
provoke the software to admit that I'm just talking to a computer.
That made me curious. With the right cues, could one make an
AI chatbot give one privileged information, like the home phone
number of the Kanopy CEO?
And why are they pretending to have tech support? Why does
a bot write to me with a name, expressing sympathy? Do they
think that's somehow more helpful?

The answer's obviousisn't it? Paying people costs money. What do you expect for free?
Apparently, enabling some kind of debugging mode can affect the results.

Debugging USB? I don't know what that would be. But I suspect
widevine is a red herring. As I mentioned, I've used 3 computers,
3 operating systems and different versions of 2 browsers. They all
fail. Yet Netflix works in Firefox on Win7 with no special treatment.

It has occurred to me that these companies might be trying to
block computers/browsers for some reason related to security.
But a browser is actually the only method they offer on computers.
The other option is apps on "mobile". Could it be possible that they
want to force apps but don't want to admit it? We have an iPad,
though I don't know how I'd pipe from the iPad to the TV. I'm
certainly not going to watch movies on a 5"x8" screen.

They have their own "in-house" solutions which might be a
bit self-serving.

Apparently a DisplayLink HDMI adapter doesn't function on the thing,
like it would elsewhere. Some of these USB to HDMI, they actually had
a CDROM section and composite device inside the USB chip, and
PC x86 drivers would load every time you plugged in such an adapter.
This would not work to make the Apple device love the chip. And even
if you find a .ko to do the job, I think there's still some technical
issues to overcome (that DisplayLink can't fix without a blessing being bestowed upon them).
It's probably faster to use a magnifying glass and pretend the screen
is bigger :-)
And remember, I've been to the ecosystem. And I've returned. There
are three Apple boxes on this desk. They hold up the other computers
(like they were "stands"). I once lost $1000 on a video card purchase
for an Apple computer, because the DMA circuit on the Nubus card
did not span all the RAM on the machine, and this caused the video
driver to crash the machine. Does that ever happen on Windows ? Fuck no.
You could say then, that I have a few battle scars from my experience,
and if I seem to be unfair to the ecosystem, there are reasons for
my answers. At one time, they were a struggling underdog of
a company. Now, they're fat cats sitting on a pile of cash,
and their old habits of "in-housing every solution" has
not stopped.
If your iPad has one of the higher speed interfaces, then the
odds improve on some display standard being multiplexed on
the device output. But then, how many displays have inputs
for such signals (without a Dock to do a conversion). And
the Dock could be relatively expensive compared to what
you paid for the iPad. I used to be able to get a VGA adapter
for a PC here, for about $25 of so. And I have a handful of those
for problem solving. The chippery inside a Dock, isn't as cheap.
Lots of libraries pay Hoopla but many don't want to pay Kanopy.
As a library patron I get to stream up to a certain limit per month.
But I've never come close to the limit because their selection
just isn't that good. And now, of course, it's not working at all.
Again, if libraries aren't paying, what do you expect?
