[Release] WidevineProxy2 Extension; Bypass HMAC, 1-timetokens, Lic wrapping

[pein]

I am getting an

ERROR: Failed to get KEY, ignore.: One or more errors occurred. (The 'skd' scheme is not supported.)

on AP*LETV+ (tried with different video resolutions). Decryption does not work, even with the "--custom-hls-key" flag. Also, the key provided by WidevineProxy2 does not seem to match the KID shown in N_M3u8_DL. Can anyone help?

If you have the right key and you want to decrypt it yourself, you have to use shaka packager and as kid you have to use all zeros, if for example you have this KID:KEY

000000003fe9e6696331202020202020:8ba8b2ba9e9f0b3f8fcb0ffa70329a27

you will have to use this to decrypt

00000000000000000000000000000000:8ba8b2ba9e9f0b3f8fcb0ffa70329a27

This is only valid for 4ppl3TV

I want to decrypt an 4ppl3 Music track, and the key is 000000006948dd06001dbd38abe5d4f2:d20bb0c49382c40ce 75ba83d1795c86f. After decrypting, I am unable to play it. Is there an issue with my command line?

command line:
packager-win-x64.exe "input=100.mp4,stream=audio,output=111.mp4" --enable_raw_key_decryption --keys "key_id=00000000000000000000000000000000:key=d20bb 0c49382c40ce75ba83d1795c86f"

ease of use?

Video not playing is a good thing for me as I don't lose limited tickets to watch.

As far as I know, on this forum we don't discuss paid services where you lose some kind of tickets each time you reload the page. Anyway, as far as I know, license request happens when the client is already aware that there is an encrypted file, so the "ticket" should be lost already. The best thing to do here is to make sure you can somehow copy the encrypted content from browser cache/memory without initiating additional requests.

What is much more important in this case, is that with WidevineProxy2 you still have to run official Widevine library, and you can't call that code trustworthy as it is intentionally designed to disrespect its "users". I believe it makes sense to replace the library with trustworthy one regardless of whether you actually intend to download anything, or just stream the intended DRM way. And the library also prints the keys to logs, which is useful.

You can still use this library together with WidevineProxy2. For some reason playback is still blocked even if the CDM is the same.

As for ease of use, building it might be complicated, but once the library is put in place, you only need to make sure you are launching the browser from a command prompt/terminal, so that you see the keys when they are relevant.

@ytdlhelp, you wrote

Can you please expand on this.

Can you please give an example of this? What command prompt/terminal are you using and what command are you using to launch the browser?

Thank you very much.

Any Linux terminal emulator, together with a supported browser. See the screenshot made with Ungoogled Chromium. I tested it with LibreWolf too. But not yet tested on Windows.

@ytdlhelp

Thank you very much for responding. Appreciated.

[ytdlhelp]

@ytdlhelp Thank you. Looks like it does not show the keys when using windows. I tried again but still no luck.

Update: Found a way for Firefox

Checked it on Windows today, and it seems you are right. When I just launch a browser via command prompt or PowerShell, there is no output. Please explain the way that you found.

[petabytenepal]

Spend whole day trying to figure out for firefox and chromium.
For Chromium, create a batch file and it will open with console and keys will be shown on console
@echo on
"C:\Program Files\Google\Chrome\Application\chrome.exe" --enable-logging --v=1 --no-sandbox


For firefox it will open console but strangely no output shown, so create a batch file and logs will be added to the file.
@echo on
"C:\Program Files\Mozilla Firefox\firefox.exe" --console > D:\firefox_log.txt 2>&1

[ytdlhelp]

I also noticed how annoying it is to build this library on Windows. Visual Studio is heavy and annoys me with licensing stuff. So I am uploading the files I built with the first CDM from here on 64-bit Windows 10. Not sure if they are compatible with everything, as I seen "win7" build targets as well, that I didn't use.

Can you help me too?

To get help, you first say what you need help with.

Hi Larley,
congratulations for your job. Sorry but I'm almost a beginner and I can't make the + button appear at the bottom of the extension. I've already tried many cdm files. The streaming comes from N*w It but I've also tried others taken from this thread. I tried both the latest version, 0.8.2 and 0.6. Same problem...

N*w? Stumped me on that one.

N*w? Stumped me on that one.

Sk* channels, but I have the same problem on all streams.It almost seems like the CMD file is not being loaded by the extension

[ytdlhelp]

If there is some wordfilter preventing from understanding what is being talked about, maybe make a screenshot where the URL is visible.

no

[larley]

discuss openwv somewhere else. this thread is for WidevineProxy2. do you think the kind of person to ask for help because they didn't click 'Enable' in the extension is gonna know how to compile a custom Widevine CDM?

OK, created a new thread for it.

These are trolls

[ytdlhelp]

I encountered larley's demo page and noticed WidevineProxy2 doesn't work on it, however OpenWV does, even if the same CDM is used. Does WidevineProxy2 intentionally lack support of something, or it is a technical limitation of the way it operates?

I solve the problem using Brave browser instead of Chrome. I don't know why 🤔

neither

[ytdlhelp]

neither

OK, I solved it. It doesn't work when "encrypt client ID" setting doesn't match the value it is meant to be. According to OpenWV, client ID encryption is supposed to be enabled for Android devices, except on WidevineProxy2 it isn't, and there is no option to fix it. So it is a bug report.

That's still not how the server's backend works

Thank you very much my friend, I was able to achieve the result, you are great
