> if using QuickJS, version 2025-4-26 or later is strongly recommended for performance reasons Oh, I wonder if they got performance to a reasonable level then? When the external JS requirements were first announced, they said it took upwards of half an hour, and a QuickJS developer wrote in the ticket that they didn’t see a path towards improving it significantly enough.

What you’re describing with QuickTime was a proprietary nightmare that didn’t even work correctly across Apple products, let alone Microsoft or Linux. Today with modern tools like VLC or MPV and ffmpeg nearly anything can be viewed, streamed, or locally saved by your average user with basic Google search skills. And the number of free and paid video editing tools as far beyond what we ever had in the past. Then there…
> What you’re describing with QuickTime was a proprietary nightmare that didn’t even work correctly across Apple products, let alone Microsoft or Linux. This is such a deep misunderstanding of QuickTime that it's hard to know where to begin. QuickTime supported standards whenever possible, but you must know that QuickTime pioneered digital video and audio before open media standards were ubiquitous, and was in fact t…
There's a reason that once alternatives became available, users left QT as quickly as they could.
QT was pioneering A/V solutions; I won't argue against that. So was Flash, so was Shockwave, so was RealMedia, and remember the horror that was Windows Media Player (from the Win98 era)?
Even when the so called "ad-pocalypse" happened, this wasn't as big of an issue as it is today. What's going on with Google being extra stingy seems to correlate well with the AI boom (curse). I suspect there are companies running ruthless bots scraping TBs of videos from YouTube. Not just new popular videos that are on fast storage, but old obscure ones that probably require more resources to fetch. This is unnatura…
Yes, the regulators will try and manage it, but eventually every decision about who can use the robot/AI genie for what will go through them because of the robot/AI genie's enormous strain on natural resources, and you'll be back to a planned economy where the central planners are the environmental regulators.
There are hard decisions to make as well. Who gets to open a rare earth processing plant and have a tailing pond that completely ecologically destroys that area? Someone has to do it to enable the modern economy. It's kind of like we won't have a good AI video generator and will always be behind China if some Youtube creators refuse to license their content for AI training. Same goes for the rare earth processing tailing pond. Nobody can agree on where it's going to go, so China wins.
I don't mind, but it has to work out of the box after a pip install. Looks like the packaging will be a mess?
What do you mean by it has to ?

And it's an entirely useless effort. No idea how it is done but the internet is full 4k rips.
Breaking HDCP is a lot easier than breaking the other things. You don't have to attack the torment nexus directly. This is not the most ideal option but it is information theoretically correct assuming your capture rig is set up properly.

They find devices that are easy to hack (and I mean rip and tear) and extract the decryption keys from each of them, from what I have heard cheap chinese tvs and set top boxes, they extract the keys from the chips (hardware hacking, heard some even use microscopes to read the keys by hand), and then use them to decrypt streams, I heard that they catch them pretty fast to they use like 1 device per season. This is why…
The really shitty thing is that vulnerable devices get blacklisted en masse, so all legitimate users get stuck with 480p video content on streaming services. The Nexus 5 got this treatment, as I understand it, because it was too easy to extract the keys.

> Although it will be a lot slower, I’m not clear just how slow. Around 30-50x slower than V8 (node/deno). I've been recently benchmarking a lot of different engines: https://ivankra.github.io/javascript-zoo/
> Around 30-50x slower than V8 (node/deno). A solver running at 50ms instead of 1ms I would say is practically imperceptible to most users, but I don't know what time span you are measuring with those numbers.

Because taking money from a con artist to deliver marks based on profiles you've collected on everyone to see who's most likely to be taken in makes you an accessory if not accomplice to fraud. Businesses (in particular the literal biggest ad agency in the world) should know who they are partnering with. Not vetting the people they're allowing to place ads is at best negligent. The fact that the FBI warns people to u…
That's a fair point. Thanks for the detailed response. I'm curious as to what the scam ads you mention actually are. I use an adblocker most of the time, and most of the adverts that I do see are annoying but fairly innocuous. Furniture, insurance, charter schools, social media apps, shitty mobile games, et cetera. I've seen plenty of slightly scummy adverts, but I can't recall seeing many that are really harmful or…
Additionally, Google has a well known policy of allowing people to take out ads (which look exactly like a search result) for someone else's trademark (defeating the entire purpose of a trademark), and the FBI has a frequently referenced notice[2] to US citizens to be aware of fraud where scammers take out impersonating ads on "Internet search results" to e.g. lead people to the wrong site for financial institutions. It absolutely blows my mind that no one is prosecuted for participating in this.

Those programs which cannot so expand are replaced by ones which can."""" and """Greenspun's tenth rule of programming is an aphorism in computer programming and especially programming language circles that states:[1][2]
Any sufficiently complicated C or Fortran program contains an ad hoc, informally-specified, bug-ridden, slow implementation of half of Common Lisp."""
(from the above I conclude that if you want to take over the computer world, implementing a mail reader with an embedded Lisp).
I use yt-dlp (and back then youtube-dl) all the time to archive my liked videos. Started back in around 2010, now I have tens of thousands of videos saved. Storage is cheap and a huge percent of them are not available anymore on the site. I also save temporary videos removed after a time for example NHK honbasho sumo highlights which are only available for a month or so then they permanently remove them.
