Any solution for this problem ?

This is not directly related to the addon but I wondered if you could shed any light on a problem I have as you appear to know a lot about Netflix's MSL.

I have developed my own media player over a number of years and for the last few months I've been trying to natively play Netflix media. I've used the Kodi source as a guide although all of my code is in C#.

I can retrieve the manifest for a movie or TV show but no matter what I have tried the licence request fails with 'This title is not available to watch instantly'. I pass the session ID and challenge that I've obtained by starting a session using the Widevine CDM in the licence request.

I have used the addon to compare what Chrome is doing when a Netflix movie is played against what I'm doing and they look pretty much the same but still no luck. Incidentally Chrome seems to do things a little differently to Kodi, at least according to the Kodi source I looked at fairly recently.

Any help would be appreciated but if you are not interested that's fine too.

The Netflix msl request to https://www.netflix.com/nq/msl_v1/cadmium/pbo_logblobs

is hard to read as a human.
Up until the languages part you can use beautifier io to add indentation, but the quotes and triple backslashes in the params section completely negate this.
Maybe some string replacement would be good here to help us format stuff like

\\\"params\\\":{\\\"uiLabel\\\":\\\"standard\\\",\\\"trackingId\\\": better

Hello bro, I'm sorry for bothering you but i need to understand something, is this script used to decrypt the Netflix msl-v1 content and response data?

If yes then i want to understand something, i followed your tutorial on Netflix ( on my iPhone ) and i indeed can see the requests urls but i can't access to data nor headers and even the log files is empty, so what's exactly going on

hi,

I get this error , am i missing anything?

site-packages/mitmproxy/net/http/encoding.py", line 76, in decode
raise ValueError("{} when decoding {} with {}: {}".format(
ValueError: LookupError when decoding b'\xd9\xd9 with 'msl_v1': LookupError('unknown encoding: msl_v1')

Here is the version i have

Hello,

I'm trying to see the MSL requests in chrome and the .log file shows:

And I see in CMD some errors like ::

Please keep in mind while the mitmproxy is running, no movies or shows would play in chrome and I end up with an error : https://i.imgur.com/lwjDBB6.jpg

Is it normal to not be able to actually play anything?

Also, It would be nice if you can explain how can I decrypt those requests to be able to see them after acquiring that info as I have no idea how to replace the Client pubkey and I see no data in the .log file.

Thanks!

Where does the msl_decrypt.py file have to go?

I'm not familiar with Python so this is in idiot question but I've tried many different locations and just keep getting the following message when I try to run mitmdump

C:\Users\User>mitmdump -s msl_decrypt.py
C:\Users\User\AppData\Local\Programs\Python\Python37-32\Scripts\mitmdump: No such script

I can successfully run mitmdump without the script.

I reseted whole app, tried reinstalling, clearing cache, everything but still doesn't handshake to netflix API, i could not see the traffic, can you double check if it needs update or im i somehow missing something

Is the plugin supposed to decode all base64 strings into ascii if possible?

Used this script before and it works great. Trying to install on a new machine and having problems. Can't get past the mitmproxy install. I installed python and did "pip install mitmproxy" and get the following error. Googled pep517 problems, but no luck. the Microsoft vc++ runtime is there. You need to install from the command line and not use the windows installer, correct?
