I use the code yt-dlp python yt_dlp -F -v https://iframe.mediadelivery.net/embed/64132/dc70003f-3dc9-4ea0-851b-6a8e0a8e928f
have this error

grateful for your help

[Obo]

Use "yt-dlp --no-check-certificates".

Tip: "yt-dlp --help" tells you about all available options; it's really useful to at least once skim through.

The GitHub script needs to be changed for hls aes I think. If you want a easy solution without caring at all about their joke of pinging mechanism, you can download this using Tubedigger or you can code your own tubedigger mini script for that page (so you won't pay a cent for that software if you aren't a fan of paid software). I checked for the first few fragments and they can be decrypted. Each fragment has a unique key though.

[2nHxWW6GkN1l916N3ayz8HQoi]

Yep. Seems I was right. I really have no idea if there are other resolutions hidden but from what I see at first glance 720p is the highest. They really went hardcore on that pinging mechanism there.

Luckily you can throw their ping to the trash by injecting some JS code. If you have no idea what I'm talking about just skip the entire post and just get the download link at the end. First of all, find the function of interest that you can use to download each fragment (use Chrome to make it easier to edit stuff, I dunno how to get Firefox to auto-format page source code ). It is found in hls.min.js

onSuccess: function(e, i, n, a) {

Outside of that function, you need to add some "global" declarations for the following variables. You'll have to figure out where to add them exactly.

var keyMap = new Map();
var COUNT_KEYS = 213;

The COUNT_KEYS variable can be found at the end of the m3u8 stream found in the network requests (in this case 720p).

720p.drmkey?v=213 is the last one.

Moving on, the detected function (the onSucess one) contains some existing code which we're going to ignore completely. The code we're gonna add focuses on 2 parts: getting the video fragments and getting the keys. For some reason apparently at each refresh of the page that function receives different encrypted fragments with different keys (why though, I have no idea). Anyway, in theory, if you get those fragments with their respective keys, you can decrypt locally the m3u8 stream.

The part that deals with getting the video fragments is put at the beginning of their function.

let videoNumber = e.url.match(/video(\d+)\.ts/i)[1];
const fragmentBlob = new Blob([new Uint8Array(e.data)], {
	type: 'application/octet-stream'
});
const downloadLink = document.createElement('a');
downloadLink.href = URL.createObjectURL(fragmentBlob);
downloadLink.download = "video" + videoNumber + ".ts";
document.body.appendChild(downloadLink);
downloadLink.click();
document.body.removeChild(downloadLink);

So then the video can be played at 4x, 6x, 8x, whatever, and you're going to download the fragments very fast. Be careful, there is a limit so not too fast. I tried to find a clever way that can force it to the max but the arraybuffers used by them are detached. So manipulating them is a major headache to figure out (at least for me so I dunno).

Then the getting the keys part is added at the end of the function.

let keyIndex = parseInt(t.decryptdata.uri.match(/\?v=(\d+)/i)[1]);
keyMap[keyIndex] = t.decryptdata.key;

if (keyIndex === COUNT_KEYS) {
	let concatenatedArray = new Uint8Array();

	for (let i = 0; i <= COUNT_KEYS; i++) {
		concatenatedArray = new Uint8Array([...concatenatedArray, ...keyMap[i]]);
	}

	let batchBlob = new Blob([concatenatedArray], {
		type: 'application/octet-stream'
	});

	let downloadLink = document.createElement('a');
	downloadLink.href = URL.createObjectURL(batchBlob);
	downloadLink.download = "keys.txt";
	document.body.appendChild(downloadLink);
	downloadLink.click();
	document.body.removeChild(downloadLink);
}

Start the video. Raise the speed very high (5x-8x I think, you may use an addon for that speed). And at the end, you're gonna have all the fragments and all the keys into one single keys.txt file. Then use a script to split that keys.txt file into separated 16-byte keyINDEX.txt files.

import os


def split_into_chunks(file_path, chunk_size):
    with open(file_path, 'rb') as file:
        index = 0
        while True:
            chunk = file.read(chunk_size)
            if not chunk:
                break
            yield chunk, index
            index += 1


def write_chunk_to_file(chunk, index, output_dir):
    file_path = os.path.join(output_dir, f'key{index}.txt')
    with open(file_path, 'wb') as file:
        file.write(chunk)


def split_file_into_chunks(input_file, output_dir, chunk_size=16):
    if not os.path.exists(output_dir):
        os.makedirs(output_dir)

    for chunk, index in split_into_chunks(input_file, chunk_size):
        write_chunk_to_file(chunk, index, output_dir)


input_file = 'keys.txt'
output_directory = 'output_keys'
split_file_into_chunks(input_file, output_directory)

Then you're gonna have to obtain a sample m3u8 file from the network requests. Just copy and paste the output. In this case, it is a 720p m3u8 stream.

You're gonna have to replace all http links related to keys looking like "drmkey?v=INDEX" with "keyINDEX.txt". So it becomes a local resource.

import re


def replace_links(input_file, output_file):
    with open(input_file, 'r') as fin, open(output_file, 'w') as fout:
        for line in fin:
            matches = re.findall(r'(https://[^"\']+drmkey\?v=(\d+)[^"\']*)', line)
            for link, number in matches:
                line = line.replace(link, f'key{number}.txt')
            fout.write(line)


input_file = 'input.m3u8'
output_file = 'output.m3u8'
replace_links(input_file, output_file)

Then using a simple find all + replace in a text editor, remove the base URL of all videoINDEX.ts fragments. So they become all local resources. Doesn't matter if you keep the query parameter, just get rid of the URL.

I really don't know if there is an easier way. I guess you could do this with tubedigger if you bought it. By using this approach you could totally ignore whatever modifications they could introduce in the future to the existing ping mechanism.

Marvelous job pepe! I applaud you.

Agreed! That was one hell of a ride!

Thank you both @vegeta and @white_snake for the kind words! To be fair, I don't think of this as something groundbreaking and I'll try to explain in a few words why (short answer, it is boring and cheap). Across the years I've seen many sites that use tricky convoluted ways like this to hide the video, I've seen the usual flow that happens when a solution is found.

The site uses a dubious method/protocol etc. to protect the video against trivial tools (yt-dlp, N_m3u8, etc.) -> someone reverse-engineers that mechanism and posts it somewhere for the end-user to utilize -> the tool/script, etc. gets popular -> the site makes the dubious method even more dubious and convoluted -> .... -> cat/mouse never-ending game

And I thought why would someone put themselves through that hell haha. Without any paid software, one could do this with minimal programming knowledge (obviously it is different from site to site, I just provide the general flow).

The site uses the dubious method -> debug the code and look for relevant information -> know what to look for and find some magic function that deals with the video fragments -> inject js code -> refresh the page and max up the playback speed -> download all video fragments and other relevant data (depends on the case, this is just general) -> process the downloaded data -> final video done.

So you just skip over whatever they're doing to protect that video. Of course, this line of thinking can be stopped and I've seen sites where it doesn't work. Some sites thought of this from the start, and some didn't. And to fix your site to defend the video from this strategy, would mean some serious restructuring of the code and rethinking of how the video is sent. And that is not trivial at all. There are ways to defend against this and ways that I'm not even aware of.

Would that mean that iframe mediadelivery is going to start changing the code to avoid that? Well, I have a personal unproved theory of mine. If a method for downloading can't be widely used by the general public, then they probably won't bother at all. However, that is unproved and only time will tell. Looking forward to what they come up with since I like seeing new stuff. And if they fix it for good, it is what it is. Then only the reverse-engineering strategy remains and keeping it as private as possible.

The nice thing is that this approach works on a good part of tricky sites. Kinda off topic but if someone is interested in seeing it applied in some other context, you could read:
https://forum.videohelp.com/threads/412993-How-to-download-a-video-of-higher-quality-f...x)#post2719620

I personally call it a funny name, the caveman approach, since you actually deal at almost the lowest level with that site. By digging into that messy obfuscated source code. There is a lower level than that and that involves WASM. But that's another topic and one I don't have a lot of experience in, unfortunately.

Is it cheap? Oh, for sure, definitely haha, and quite boring. Is it effective? Yes. I think that Tubedigger uses the same line of thinking but I don't know for sure. I still think the proper solution to this problem is to fix the pinging script. That being said, my bad if I went on quite a ramble there.

I've read it three times and I'm still scratching my head.

I'm sure you will figure it out eventually

some things I don't understand, but I'll try
thank you

You're welcome. I personally advise you to wait for the ping script to be updated. Maybe someone (or even the author himself) can look into it. Very cool of MaZED-UP to provide this script that can be found here (I dunno if there are other solutions/pages):

I posted the solution more for people who do have an idea of what is going on with the source code. If you do try what I posted without some background knowledge, then I'm afraid I won't assist you. I really don't mean to sound rude but I honestly don't have the patience to deal with every little thing and explain from scratch everything (I kinda suck as a proper teacher). Kudos to the users that do have the patience! Hats off to them.

Maybe someone can actually incorporate this into a browser addon or something else that semi-automates the task at least. However, I don't have the expertise necessary, nor the interest to do it.

Thanks for sharing


You have so far demonstrated a proficiency in python, bash shell, powershell, curl, sed ,awk, grep, xargs, tr and now javascript. You continue to amaze.

You're welcome, and again, thanks for the kind words @jack! I have to thank my former college professors for that knowledge. Much respect for teachers!

Have a questiion.


Can you post the contents of the "keyINDEX.txt"


Thanks

Sure. I'll post the original m3u8 file, the final processed m3u8 file (both as txt so I can send them), and the full keys.txt file that contains all the keys appended. The size of keys.txt is 3424 bytes. 3424 / 16 = 214 (don't forget it starts from zero index). So you need to split into chunks the keys.txt file with the script I gave previously. 16-byte chunks because obviously, a key for hls aes 128 is 16 in size.

keys.txt

original_input.txt

processed_output.txt

I'll also post the encrypted video fragments in a zip if you wanna play with the encrypted stuff. I've seen that at every refresh of the page, you get a different videoINDEX.ts encrypted file and also a different keyINDEX for that ts file. I guess that they use some form of key rotation mechanism (I could be wrong though, needs some research).
