There is a confusion about Widevine security levels: Widevine security level (1, 2, 3, 1 is the highest) and Widevine API security_level (1, 2, 3, 4, 5, with 5 being the highest). The above 2 samples are for API security_level = 1, so they are NOT Widevinne L1. Below is a sample with Widevine security_level = 4 which maps to Widevine L1.
This sample, for example, does NOT play in Chrome since Chrome does not support Widevine L1. It works on newer Android which support L1.
For the exact mapping of 2 Widevine security levels, please see my doc https://video2.skills-academy.com/en-us/azure/media-services/previous/offline-widevine-for-android#frequently-asked-questions (the table in the 2nd question of FAQ section).
