doubt it, should be on OS level, gpu control for all possible vendors and output formats is impossible without gpu driver support.

It's specific to the Intel GPU. Intel PAVP (Protected Audio-Video Path). See page 192 of Intel's "Platform Embedded Security Technology Revealed" (2014), https://link.springer.com/book/10.1007/978-1-4302-6572-6

The person I’m replying to make it sound like Xbox Dev Mode came about because Microsoft was tired of trying to keep hackers out, but the reality is Microsoft has kept hackers out. You can’t jailbreak an Xbox One.

If I recall correctly, Microsoft was about to cripple down the Dev Mode, what caused in the community, what led to increased interest in hacking X1, what made MS back off on their decision, after what the discussions quieten down. I won't claim Dev Mode is their solution to hacker, but there seems to be some correlation.

I’m not sure why crippling a niche feature would drive people to try to jailbreak the Xbox One. It really is a useless feature unless you are developing an app/game for the Xbox One- then you won’t have to spend however much on a dev kit.

I believe indora has already said why under your initial comment:

>Most of the piracy scene depends on hackers figuring out how to break security so that they can run [SWEET DEMOS](...) and homebrew apps on it

That's definitely the experience I have with modding scene; piracy is rarely the primary goal. Yes, Dev Mode is a niche feature, but it's a feature appealing to the hacker's niche.

Yup, MS really threw it all away with their Kinect play.

And then they took this strategy into the XBox One generation: everyone gets a Kinect! For $100 more than the competition! And it's always listening, and you have to have it connected for the system to boot! Piling onto that with "we're getting rid of game sharing or the resell market" and "our new console is going to be your entertainment hub, i.e. it's going to be jammed full of shit most gamers don't want!" and th…

Xbox One premiere was a disaster since the design reveal. I saw it and was like "you must be kidding". Original X1 doesn't look like magnetowid - my magnetowid looks way better! Xbox One S is what X1 should have been since the very beginning.

Yeah the only issue is that dev mode doesn’t enable would-be hackers to do any of that stuff.

Microsoft really seemed to be ahead of the curve with console security. They really thought this through back in 2005 or so, to the point where clearly, they knew people would hack the drives to rewrite the serial number. It's probably for the best that they never actually did anything about the knowledge that gave them, but they clearly stayed a step ahead of the game. As much as I hate it, their actions show a grea…

I don’t think Xbox Dev Mode is really worth a damn. You can sideload apps but it’s not a vector for piracy or running Windows or Linux. PS3 Linux was about as useless as PS2 Linux, because the PS3 had only 256MB of RAM. I put Ubuntu Server on one and used it as a Squid proxy server to route P2P traffic through to the university’s college of computing since P2P was blocked in the dorms. For some stupid reason I totall…

I don't think ps2 and ps3 linux were intended to be used, ever. From what i can tell the only reason it existed at all was to allow sony to import it as a computer rather than a game console, which has higher tariffs imposed.

You can produce pixel perfect rips. But since the resulting video file is so large you will "need" to compress it, and then you get compression on compression artefacts.

Yes, indeed. Pixel perfect rips of already compressed streams, immensely blowing up the size and requiring another round of lossy compression to actually be useful.

And the result after recompression is impeccable so it is not a big deal. It is just a bit cumbersome.

The result after recompression is far from impeccable.

On high bitrate content you wouldn't notice.

It's literally what it's for though?

And from what I see, stuff like RetroArch can be run on normal console even without Dev Mode nowadays. Heck, you can play NES games directly in Edge browser without any shenanigans.
