Looks like you need to downgrade the py module "protobuf"

pip uninstall protobuf

Y

pip install protobuf==3.20.1

Hi,

Being new to this world, I've followed this guide and had fun learning a whole new language and a ton of fun stuff along the way, but haven't managed to get any keys generated.

On both Windows 11 and a MacBook (Apple chip) I've got as far as having the emulator running, having Frida and the Frida server running, and talking to each other, but when I go to the sample video site or others (I tried BBC/ITVX) I don't get the two files being created. On the sample site, it does show as being Wildvine being used.

The one thing I have had to do on both systems is to downgrade protobuf to 3.20.1 as documented here in this thread to get dumper working. Would that be the cause or is it something else I've missed? I saw another post here from A_n_g_e_l_a regarding getting protobuf working. I did try this on the Windows box, but got into trouble with some c++ compiler flags specific to Windows that I didn't want to tackle unless I had to (I haven't tried doing it on the Mac yet).

Any sage words of wisdom, or should I carry on trying to get pywildvine, dumper and protobuf working happily together?

Possibly a stupid question, but you did run "python dump_keys.py" before playing the video on bitmovin (or w/e), didn't you? Asking because I see no mention of it in your post.

Protobuf 3.19.3 recently worked wonders for me. Also pywidevine has got nothing to do with dumping CDMs. You might also want to give a shot to this dumper.

I sure did, but good question.

I tried that dumper and had no luck either.

Nothing gets created after opening the demo URL and playing the video.

What Android version are you trying to dump from? Is it possible that you're using a non-Google APIs image?

Had that issue. Need to run Android Pie.

[thundertwonk]

I used a Pixel 6 from the Android Studio so I'd assume that was as Google as it gets? It used the default of Android 14.

Had that issue. Need to run Android Pie.

I can try with 9 / Pie and see if that makes a difference.

Edit: Actually, I missed that part in the instructions. It does say to use Pie.

And that worked. At least it generated the files. Now onto learning something else new... what to do with them
Thanks for the support.

[informer122]

once you have 2 files i m new at this drm thing
how to convert to key or kid
any help would be appreciated
any next guide

[T33V33]

try the other sticky posts... they are pretty much guides to the whole process

[fma15]

I think I followed the guide perfectly, but it doesn't seem to work for me. Both command prompts are open both of them are on this step




When I go to https://bitmovin.com/demos/drm nothing happens. The video plays fine, but above it it says "Detected (chrome icon), using NO DRM. I don't know if that has anything to do with it or not.

[white_snake]

it says "Detected (chrome icon), using NO DRM. I don't know if that has anything to do with it or not.

Yes, that's definitely a problem, it should be using WideVine. Are you by any chance running a non-Google APIs image?

[fma15]

I don't think so. I'm using a Pixel 6.

If I scroll down it says EME is not supported by your current browser.

If I were you I would try different sites like: https://www.nuevodevel.com/nuevo/showcase/drm

And/or another browser like Firefox.

Thanks! The other site worked.

But my installation always ends up with a picture
Where is the problem?

Do you have Python installed? https://www.python.org/downloads/windows/

[ghost66]

I have python 13.12.1 _amd64

[white_snake]

I have python 13.12.1 _amd64

It doesn't look like you have pip installed though, which is weird. See here: https://pip.pypa.io/en/stable/installation/

I stayed at this step
Where do I make a mistake?

[PSXman_uk]

Fixed had another adb.exe in path from another programme

It's the same thing as before, Windows can't find your python executable. You have to add its location to the PATH.

Can I create multiple phones and create multiple keys I'm assuming you can unless its via ip ?

[Karoolus]

I have dumped hundreds from Android Studio, all on the same PC. So yes, it works

[PSXman_uk]

Do you use the same Vm for each set of keys or new vm each time

[Karoolus]

with VM you mean Android AVD?
