There is a trick to record Netflix from Chrome. Just inspect the element and add this style: `filter: blur(0px)`. Now use any screen recorder. Video stream will get recorded.

Does this work only on netflix or on every drm protected site
this might be really really cool thing you have just told me
and does this work only on chrome , what about firefox?
what if we change our useragent to chrome windows but we are using firefox linux for example
DRMs cannot protect from virtualization and screen recording.
Create a Virtual Machine, add your streaming service in it, record your screen from the main machine.
but playing the video on virtual machine itself will be limited to 480p as there is no hardware acceleration available with vm.
I'm confused. What is VMGL?
It can, there is no virtualization for TEE
@@neerajbhale Hardware acceleration is available is many VMs now and its not limited to 480p. You can play upto 4k if you have a powerful system
Are you sure? The DRM video cant be played inside VM. it stucks indefinitely. Even if it plays, recorded video wont show the DRM video, and the frame where video was playing will be shown as black box(similar to the example in this video).
PS: I tried this with primevideo on windows10 vm hosted by Ubuntu.
Great Video! Explains why you cannot download DRM protected content but doesn’t really explain why you can’t screen record netflix content
You can't record screen record , its a browser feature not Netflix. You have to disable some settings in browser to stop Netflix applying such security
Hardware or GPU Video acceleration needs to be turned off in browser settings
HDCP.
you can screen on linux with no problem on firefox at least
@@mannumannu9200how to do that??
That's really good explanation! Though it's funny that all of this is evaded with just Virtualbox 😅 and I think there are devices that can capture the monitor's HDMI output doing it on a hardware level. I know there are harder solutions like fingerprinting could be a good idea to add to your solution too.
Virtualbox cannot talk to the hardware chip based TEE, and for HDMI there is HDCP , for widevine L1 both are required. You can capture only L3 at max
Some people mentioned using capture cards. That would be a WEBRIP instead of a WEB-DL. A WEB-DL is the direct decrypted stream from the platform and it can be downloaded in just seconds. To do a WEBRIP (i.e record) you would have to do it manually and it's too time consuming. Also, you cannot download multiple titles at the same, time and the quality is shit compared to a direct download of the service.

This video literally put my brains on fire 🔥🔥 Though I am a dev myself, sometimes I go crazy when I think how much energy and hard work tech companies put into a project just to keep some thieves at bay
It’s next level. I tried recording the tv using the camera in my phone and the picture went black just like what he showed.
It's worse for me. I have a photographic memory and the screen goes black as soon as I look at it :(

What do you mean ? I can perfectly record my tv with my iPhone, I have video and audio
Bruhs got L1 Level of Sarcasm 😂😂😅
There’s some hardcore engineering going on in the world, and folks here in India are chatting about DSA vs. dev! 🤦♂
Edit:
Quite a few people in the replies clearly lack basic common sense and are getting triggered just because I mentioned DSA.
They seem to think I’m saying DSA is useless, which I never said. By that logic, you could also infer that I’m saying dev is useless.
What I’m really addressing is this absurd, baseless debate of 'either DSA or Dev.' If you’re pursuing computer science, DSA is a must-it's not optional. There shouldn't even be a debate about this.
Yes bro we fucked up
Fact of the matter is companies are be promoting the DSA demand for filtering out easily.
That's I want to also say, thse Yt wala bhiaiya, didi, bhabhi have runied the engineering ecosystem of India.
And stupid students are blindly following the DSA cheatsheets only.
Have always been like this. It is because we have blinded by the money. Everyone is chasing that.
Am a senior developer, and your completely wrong here , you need mind and logic building to do these kinds of things , for those we need DSA , DSA is not just about solving problems it's how you approach them.
It's very easy if you're experienced enough. No matter how securely the file was encrypted, to play it back it must be decrypted. So the decrypted content and the key must be somewhere in the system memory. Software might not be able to access it, but if you tap into the data line of the memory chip, the key will eventually appear so you can grab it and decrypt the video yourself. Or the decrypted video will also appear. It's a time consuming progress to put it together from the pieces, but it's not impossible.
Hey , can you do it for me please , i have purchased 1 batch's course but due to internet issues i can't stream it at my home , and it doesn't allow download , like it has in app downloads but has some glitch in it.. so it saves the file in a bin or maybe it's an encrypted format , so i want it in a video format . Can you?please!
@ronikagrwal Unless it's a Netflix like thing it might not be as secure so you can do it in an easier way. You can check if you can catch the delivery of the key by pressing F12 on the page that plays back the video and reload. You'll see a bunch of things but one is the video link that should end in either m3u8, mp4 or ts extension and most probably will have a bunch of URL parameters. Or it could be an xml, manifest or something like that. If you inspect this you'll either find the key in there or a link to the license server that will serve the key. Don't try to open the link, it won't work! Instead, start the video and you should see the file in the link appear. Inspect it and it should contain the key. Use this key with a decryption tool like OpenSSL to decrypt the video file. The bin file might not the video you're looking for but the manifest file you've inspected earlier should contain the name of the video files or pieces of it. You can download these and use the key to decrypt them. Each video will have its own key but if one video is in pieces, the same key will work with all of them. I use this method to decrypt sport content from the government broadcaster (which is free so I'm not sure why they encrypted the video, but they did).
Of course, it's very easy to take a DDR stick and inspect every byte while it's still hot (data disappears shortly after it's disconnected from PC)
thank you for the great content! I've come across this and I've hypothesised that "true" encryption is not possible and feel humbled by the great engineering that has gone into this.
Hey Mehul, the video is very very Impressive, but I am genuinely impressed with the marketing of fermeon as a platform. It's really great that you are genuinely and organically marketing a platform of your own and not by any shady ads or anything. Hats off man!
Nah it's scummy he should disclose that he has vested interest in fermon. People who are just watching his video as a one off will not have any idea that what he is talking about is owned by him or gives him a financial gain if used by his viewers.
@shoraz Your point is great. He should mention that.
This is some crazy good content! appreciate the knowledge and effort. keep this going and you wont need any clickbait thumbnails anymore. honestly, I avoid watching catchy thumbnail videos.. but i watched and loved this one because of the content. its great execution.
Yeaa I too avoid those type of videos😊
Same😊
So does it mean that if I am watching a video on Google Chrome on Android or Windows, I am watching in 720p, but Netflix is charging me saying that they are providing HD content?
Y E S
you really gotta be kidding me to pay for movies 😂
Why are you using Chrome? Use the app.
@cannotthinkofanybetterhandle The real question is, why are people still using Netflix?
@@firestormjupiter what is a better alternative?
Personally, I don't watch movies or series much but I do like to play games and tbh DRM actually hurts the performance and its highly invasive to the Kernel level.
If i am not mistaken... You can record/use virtual cam on drm videos using for example Obs. Just turn off hardware acceleration on your browser and you should be all set up
So that explain how netflix ended the piracy issue?! Good job guys, keep it up, you are doing great!
😂 This is the best sarcasm
They didnt end shit. The content is ripped minutes after release for 1080p and every few weeks in bulk for 4k
@@bidfrust This. I'm in a release group and we have an automation (similar to the *arrs) to download automatically new content released.
Thank you for explaining the whole encryption part and how exactly media streams played using the security built on top of the servers. That was insightful. Hope next time you may get something similar like screen share enabling the same for some of the application.
Man since i subscribed to your channel today in just few hours i learned alot of things glad youtube recommended this channel to me.
I was looking for this kind of video, because I always get fascinated about how this thing works. Got the basic idea will do my own research to get more clear understanding of this
How to bypass drm protection very very easily : grab a firestick or any device with hdmi output, use a cheap hdmi to usb capture card 10 to 15 usd, plug into pc, open obs and record whatever you want
This wont work because TEE knows the HDMI device connected is not trusted.
@@NileshAkhade it will work if you change it from firestick to a chrome based streaming service because its only L3 TEE

Thanks for this video. This is basically sandboxing the client browser layer which is playing the video. There is still some client detection part which I guess may be important in this context so that people know how the recording trigger is detected etc.
All these hoops and Netflix videos still get pirated 🤣
Isn't that mean they are more intelligent?
How do they do it any idea?
Yeah i am interested how movies website like modlviesmod pirate that
Once the video leaves from the HDMI port its insecure😌. They maybe using some kindoff HDMI recording solutions which can capture both video and audio.
@@kushaalrana Using fapstream
You explained the Crux of it. Thanks. I work on an OTT company. Will share it across.
If you could make a video on how you have these videos on CDN like Akamai that would complete the flow of video distribution
also let them know that if buying isn't owning, piracy isn't stealing :")
@@anupamdash1102 YEAH !! LETS GO !! Break the chain !
So basically it doesn't actually protect from piracy, but requires you to install proprietary stuff and leak a bunch of info to Google.
Neat.
Thanks for the explanation!
with this, you can also get an undesired bug on macs running the m chips, and which make use of docking stations with displaylink technologies. since mac treats the extensions of screens on displaylink technology as "your screen is being observed", meaning the flag is triggered, if you wan to play netflix on your secondary screen, it will play it blank. pull out the docking station and the video will play as expected... so this thing is tricky altogether.

This was so informative. Now I know why Prime Video doesn't play at highest resolution on macOS Chrome, whereas Safari can play it flawlessly.
You are one of my favorite dev channels. The content you put out is such high quality, wishing you more success.
there i a simple workaround to record netflix. SStep 1 - download an secondary browser (edge ,
chrome ). Step 2 - dissable Hardware/GPU acceleration ijn that browser. Step 3 start recording using OBS studio. This work flawlessly on edge for me.
You can disable hardware acceleration in your browser to fix black screens when sharing or recording streams. However, this might result in receiving the stream at a lower quality.
Hey, Mehul thanks a lot man for making such videos. Though I'm a beginner in this journey but such videos can give us some new goal or we can use all these technologies in our projects etc. Your such videos are like introduction to new tech for people like me. : )
This channel is a goldmine!
Leme give a good trick, Turn off hardware acceleration in chrome or any browser, you can now even live stream it 😂
this can easily be circumvented by using a capture card on the display port and recording the audio as well, sure you might need to recompile the audio and video with a very slight quality hit but yeah it can definitely be done.
That would be a WEBRIP instead of a WEB-DL. A WEB-DL is the direct decrypted stream from the platform and it can be downloaded in just seconds.

Such an interesting and clear tutorial. Thanks a lot Mehul!
Then explain how websites such as fmovies put these netflix movies on the same day they are released on Netflix?
The reason they can keep doing it is because most people have no idea how it's done. Even if netflix knows how it happens, they might not patch it because the knowledge is not available to most of their actual customers who would have real benefit from it
Hdcp splitters, they can remove protection from between the fire tv/ roku tv and the hdmi monitor... and some lab setup receiving the hdmi ... idk how the captions are captured tho, if not manual (unless captions aren't drm protected)
there's probably like 20 different workarounds, so Netflix movies/series will always get pirated, but you as a legitimate user still can't make a stupid screenshot
@@shadesoftime btw they actually do it, bc it's so easy to patch it.
Thanks Mehul, Quality Content 🔥. keep them coming more
You said how it manages to play, but WHY it gets BLANK WHEN WE RECORD IT?? And You're correct that Chrome's DRM (Digital Rights Management) typically limits Netflix playback to 720p. However, Netflix uses additional technologies to enable higher resolutions: Netflix's 4K playback requirements: 1. Widevine DRM L1: Required for 4K playback. Widevine L1 is a more secure DRM level. 2. HTML5 Premium: Netflix uses HTML5 Premium to deliver 4K content. 3. Google's Encrypted Media Extensions (EME): Enables DRM-protected content playback.
If I get what you asked, TEE see some traces of video recording software through metadata it consumes and returns grey picture frame instead of decrypted one.
But as far as I've got, you are better with this kind stuff, so you already know the answer.
Only 480p playback is visible to user processes which is decrypted by L3 as software plugins. L2 and L1 which is 720p and above are decrypted in OEMCrypto module in TEE which makes the rendered stream invisible to all user processes which includes recorders, L1 goes one step further makes it invisible to OS itself.
@ArtVorobyov
"TEE see some traces of video recording software through metadata it consumes"
TEE is a secure area of the CPU and it prevents from tampering/dumping/intercepting keys, it actually doesn't have anything to do with metadata
@pituprzz-nt1cl Thanks!
Now it's much clearer to me!
If you turn off hardware acceleration (on settings) in the Chrome browser, you can recording on Netflix and all other platforms.
Back in 2014, I once downloaded a movie using Showbox on my Android device. While going through the files, I noticed that it had downloaded all the frames, each as a tiny file of just a few kilobytes. had to stitch them all together, but there were thousands of files, and I eventually gave up halfway. not sure if Netflix on Android still does that.
Maybe you recorded HLS file. This format is used for streaming videos.
As @chetankumar9463 said, probably you dumped a HLS stream, which consists in small pieces of the video and audio. but it's probably not encrypted because you can see the frames itself. NF nor AMZN nor anyone does that
I liked your style of explaining. Mehul can you please tell me which program did you use to explain the concepts, where you write and draw lines, arrows, etc?
it's tldraw
@codedamn thankyou Bhai I'll search for it
So I will get better quality videos than what I am getting on firefox on linux, if I just cancel my netflix subscription and hit the high seas?
Unfortunately, yes. They simply don't care about users. This is just a distraction to the investors. So the platforms tells them they are safe... But safe only to the average Joe recording themselves, like in the past that you could record a TV transmission or a tape in your home VCR.
You explained a complex topic very simply. Kudos!

Hey, good content.
What's the tool you're using to draw boxes and arrows & write the notes?
Figma photo editor
Very nice explanation in demystifing DRM. Which drawing software do you use in this video?
This is was very informative. I'd like to add just one more thing. Microsoft has their own implementation using this Microsoft Edge on Windows has Netflix at 4K.
Microsoft has their own DRM system called Playready.
Correct me if I am wrong but doesn't this become redundant if you have a capture card connected to your display driver.
So you let the DRM do the decryption and just consume the audio and video streams directly.
Yea even I thought this was a work around . You could also read from a HDMI port like on a tv and reconstruct the video , I think this is called webrip format in the torrent world. Atleast this method helps that video is not torrentable before a legitimate user is able to watch it, just saves some time. I still think some people still able bypass it
This doesn't work because the TV manufacturers also implement DRM.
Look up HDCP.
HDCP prevent other devices from copying the video stream.
Of course workarounds exist, but most people are not aware of them.
people have already figured out a way to decrypt widevine L1 protected content.
couple years ago someone dropped a github repo named "Widevine Dump".
this repo included some highly sophisticated code that can download and decrypt content from amazon prime, netflix, hulu, etc.
now, we have software like StreamFab which are publicly available for anyone to use to download content from many OTT platforms including netflix,amazon prime,etc

I was watching netflix on chrome for months until I found out it is just 720p. I am still mad 😂
Wow..thank you for explaining it in a very simple language.
This is awesome content, I always wanted to know, what happen behind the scenes, known somewhat but this is majority of it
Then how can we get Netflix series and movies within 5-6 hr after launch cause if it's that difficult than no one can download only
Yes it is hard but there are groups who can extract L1 keys and decrypt videos from source but they don't tell how to prevent it from getting patched
This is super interesting, I always wondered how this works.
How does it detect if there’s a screen recorder running? I assume that’s some feature of the TEE being able to detect certain applications? I would expect that to need some kernel level code thought (that’s just a guess)
It doesn't detect screen recording.
content processing, cryptography, and control happens within the Trusted Execution Environment (TEE) of the processor which makes the media playback invisible to all the other processes including OS, That's why screen recorder sees it as black box
Since TEE makes call to licensing server, we can't use network tool like wireshark to listen to these network calls and get the decryption key ?
Also we can use Virtualization. This way, videos will be playing inside virtual machine and recording can happen on main machine ?
Aapka Knowledge Toh Kamaal Ka Hai Bhai 🤌
Nice content quick question, how does this prevent recording via external software? I mean is there some web api which can detect that the screen is being recorded or shared and blackens out the video?
This is awesome, never knew just how complex widevine was.

I learned new today about drm, but One of the best thing, learning continued also in comments😅😅,😂😂😂 thanks bhai log.
You explained the Crux of it. Thanks
If you could make a video on how you have these videos on CDN, that would be great.
I would use something like rust or nodejs that checks if there is a recording process happening and if it is, then make the screen black.
I have not tried it to get the answer, but could a video acquisition device plugged on the HDMI output intercept it after it is decrypted ?
Really amazing and well explained; Thank you very much.
actually i was try to build system which can avoid the piracy according to the chat with AI anf other resources i have as of now my approach is better than the current now watching this to check my idea is legit or not my architecture just increase 5-6 extra server requests per user hope that will be not an issue
Pretty cool video! Thanks for the explanation.
But, you still didn't tell the reason why we can't record the video through video recording/capture software.
Its fine that the vudeo is playing in a drm protected video player. But, what is stopping the screen capture utility to record that? Why aren't we able to make the drm software beleive that there is no screen recording software?
What about passthrough HDMI capture devices? Is netflix able to block that too?
Mehul sir always talks at engineering level things, not like others ❣
None of what you said explained why the screen is black when recording - that's probably just JS or CSS that can be easily disabled lol
After TEE has done the decryption, they can't stop you from capturing it - it's there in your memory registers.
"that's probably just JS or CSS that can be easily disabled lol"
nope. that's on the browser level (or in windows at OS level itself). It can't be disabled just removing that.
"After TEE has done the decryption, they can't stop you from capturing it - it's there in your memory registers."
That would be a WEBRIP instead of a WEB-DL. A WEB-DL is much much better and release groups (like me) DL.
thanks man , thats awesome information....waiting for next cool stuff like this
But how do they disable screen recording on laptops and desktop using screen recording applications?
This is great content! Thanks for sharing.
There's no way to prevent a streaming video from being recorded. All this encryption does is try to prevent a perfect copy of the sent video data from being recorded. Recording a screen can be done at an operating system level that is outside of what the browser has control over.
what is the tool he uses to draw on screen? any idea. i dont think it is excalidraw

A very knowledgeable video.
Although a pirate with video card can just capture the DP/HDMI output. But it's not a moral question, rather if someone's willing to spend the initial money because they hate netflix, because video card is actually very common.
No it cannot, there's something called HDCP for it
Although a normal day-to-day user might not bother to crack HDCP (which is not so special BTW), It is technically not impossible to do so, given that pirates go to extreme extents to copy "copyrighted" media, a home made solution can easily be made. Although you can't sell it due to legal issues.

Wow. Just wow. I'm blown. Such a great tech video.
Had to try the screen recording thing on my Linux setup, and it just worked without issue hahaha. I could record Netflix on Firefox with OBS on Wayland.
Information that you have shared is quite deep, but I don't get it drm comes in the part of encryption and decryption for content protection but who detects there's which type of screen recording happening? obs studio or other screen recording software, as in new intel series chip in windows there's whole work memorisation features which is capturing whole screen when you are using your pc.
waiting for your more information.❤
It doesn't detect screen recording.
content processing, cryptography, and control happens within the Trusted Execution Environment (TEE) of the processor which makes the media playback invisible to all the other processes including OS, That's why screen recorders sees it as black box
I once read on some OpenGL topic a feature where a buffer gets displayed so fast that it makes it "exclusive" to the main hardware display and there is no way a software can intercept the data
and it said it was the feature perfectly fits for DRM technology to utilize, is this the hardware acceleration feature?
i cant pinpoint the site but this is what I recall please enlight me if im wrong
Bro huge respect for me. I'm also working TEE right now at my job, where I'm working on deploying a web server which requires super high security in AWS Nitro enclave. Never expected this to be on an Indian ytber no offense
I know people record from netflix and upload torrents. Would be interesting if you let us knowhow that works too.
All this effort they go to, but at the end of the day the content is playing on the screen - you just need a way to screen capture without being seen by the TEE. Kernel or hardware level interventions, VMs, physical cameras, it's impossible to block.

@ Sure WEB-DL is better, I was just remarking that WEBRIP is impossible to fully block
What do you mean i can easily record it through obs and it is showing
Okay, fair, I didn't think they went out of their way this far to prevent piracy, but at the end, you could use an external monitor with apple and record whatever you want on the monitor level, in fact there are hdmi cables/adapters that save the data that comes through them
you don't even need to go that far, you just need to tweak a few styles on the canvas element in the dom and recording works just fine on any software. in the end this is nothing but wasted time and effort for the employees, wasted money for the company, and wasted time for anyone thinking these kind of anti piracy protections actually work and might get forced to implement them too. all they do is piss off actual paying customers
and this is not even considering the fact that torrents have all netflix shows from god knows where with higher bitrate than available on any netflix client a few hours tops after they appear. so even if client protection worked it's still useless in the end
@@andreibida concerning the canvas styles, no that won't work. The whole point is that you're not using css to hide the video, the TEE stops sending the video frames once it sees that you're recording, it's really amazing how advanced such a technology is. Concerning the fact that this is useless, well it is, but at the end such companies do have the resources to waste on such technologies, the small chance of having this prevent even a small percentage of piracy is worth spending money on for them, because they have a lot of it lol
@@yassine-sa It depends. Often piracy measures ruin the experience of legitimate users. While I can pirate/torrent and watch anything at 1080p or 4K as I please, due to DRM limitations a legitimate user can only watch Netflix at 720p on their Chrome browser. So IMO preventing a small amount of piracy isn't worth it as it ruins the experience of a large amount of actual users.

Amazing video man. I'll check for the paper you mentioned in the video. Could you make a video on Dynamic Watermarking? I have read about DRMs & Widevine. I'm not able to find many things on Dynamic Watermarking. All I know About Dynamic Watermarking is that it is very much resource heavy to implement, takes time & just has a hidden layer of name/user_id or something which helps us in catching the person in general.
Mehul as you mentioned that some devices like Linux or something can record or get the video out, have you thought about better solutions? We have a constraint that we can't get as good hardware as Apple has. So do we have any better options to implement? I was thinking of looking up languages like Zig or Rust or something which is close to hardware but I'm not sure if it works. Probably I'm in the wrong direction I don't know but as an Engineer I'm searching for better solutions where we don't have any control on hardware & the result to achieve is, a person is not able to download or record irrespective of the hardware they have.
No DRM or security can protect your content fully. Muti-DRM with widevine is the best we can do
Good Content.. appreciated 💯
So, TES can perform all that protection but it's useless against capture cards?
very good explanation. Thank you very much.
Security by obfuscation, it would be interesting to see if LLMS can decide some of obfuscation
DRM is powerless against me recording the HDMI output of a media player ☺️ OK, so it's a real-time process, but as someone who grew up in the 70s/80s, that's how recording video always was, so it doesn't bother me!! FWIW, this isn't something I do very often, but once in a while there's something I need/want to record 🤷♂️ HDCP strippers are easy to find. Most HDMI splitters deal with the handshake and send out two "clean" HDMI signals.
HDCP exists
@lavishjaat so do HDCP strippers 🙄
@@lavishjaat Most, if not all, HDMI splitters deal with the HDCP handshake and leave the outputs completely unencumbered and free to capture. Easy when you know how.
That would be a WEBRIP instead of a WEB-DL. A WEB-DL is the direct decrypted stream from the platform and it can be downloaded in just seconds. To do a WEBRIP (i.e record) you would have to do it manually and it's too time consuming. Also, you cannot download multiple titles at the same, time and the quality is shit compared to a direct download of the service.
@pituprzz-nt1cl thanks for the "explanation",' Einstein 😄 The quality isn't "shit" at all...if you're playing the file at full quality (ie. fast internet speed, max quality) and capturing via HDMI to ProRes via broadcast-grade capture gear, as I am, the quality is essentially identical to how anyone sees it when watching in the normal way. As I already explained, I only do it occasionally, for very specific things, so downloading multiple episodes or having it download in a few minutes is no issue for me. Thanks for "explaining" it to me though...my 35 years in the broadcast video industry really needed your helpful input 😂
how pirates bay people make a copy of it just after it releases and also release it in different resolution and codec ?
By HDCP encryption bypass hdmi splitter/switcher
(Disclaimer: I'm part of a release group)
Basically, DRM is broken by design. We have automations to dump newly released titles automatically and upload it.
@pituprzz-nt1cl for 4k quality too, i have heard higher quality streams have better protection
In any case, bravo to the community, my girlfriend has these Korean dramas in 4K HDR 2 hours after their release in South Korea.
