"""
Service code for the Netflix streaming service (https://netflix.com).
\b
Authorization: Cookies if ChromeCDM, Cookies + Credentials otherwise.
Security: UHD@L1 HD@L3*, heavily monitors UHD, but doesn't seem to care about <= FHD.
*MPL: FHD with Android L3, sporadically available with ChromeCDM
HPL: 1080p with ChromeCDM, 720p/1080p with other L3 (varies per title)
\b
Tips: - The library of contents as well as regional availability is available at https://unogs.com
However, Do note that Netflix locked everyone out of being able to automate the available data
meaning the reliability and amount of information may be reduced.
- You could combine the information from https://unogs.com with https://justwatch.com for further data
- The ESN you choose is important to match the CDM you provide
- Need 4K manifests? Try use an Nvidia Shield-based ESN with the system ID changed to yours. The "shield"
term gives it 4K, and the system ID passes the key exchange verifications as it matches your CDM. They
essentially don't check if the device is actually a Shield by the verified system ID.
- ESNs capable of 4K manifests can provide HFR streams for everything other than H264. Other ESNs can
seemingly get HFR from the VP9 P2 profile or higher. I don't think H264 ever gets HFR.
