mplv play encrypted channels from m3u playlist

Expected behavior of the wanted feature

-playing encrypted channels, m3u looks like this, single key:

#EXTINF:-1 tvg-logo="", name1
#EXTVLCOPT:http-user-agent=Android
#KODIPROP:inputstreamaddon=inputstream.adaptive
#KODIPROP:inputstream.adaptive.manifest_type=dash
#KODIPROP:inputstream.adaptive.license_type=clearkey
#KODIPROP:inputstream.adaptive.license_key=a18b6aa739be4c0b114605fcfb5d6b68:b41c3a6f7511b2e3a828d9580124c89d
https://.../index.mpd

or with multple keys, 3 or 5 keys

#EXTINF:-1 tvg-logo="", name2
#EXTVLCOPT:http-user-agent=Android
#KODIPROP:inputstreamaddon=inputstream.adaptive
#KODIPROP:inputstream.adaptive.manifest_type=dash
#KODIPROP:inputstream.adaptive.license_type=clearkey
#KODIPROP:inputstream.adaptive.license_key={15965a6dbafd12c4af6aca127b271d5b:23dd40b93306de23ec667fb17a61f322,3decf356cc9351019fb1b627b089446d:4f7e516d3253d964e55b5c36f7f65d4a,511e929c12e0596bab59b11452de49a8:6f17d11eb6e069f4165bf48b425f9ea3}
https://.../index.mpd

there is also this, but not widespread, so it is lower priority, I guess

#EXTINF:-1 ,name3
#EXTVLCOPT:http-user-agent=Android
#KODIPROP:inputstream.adaptive.license_type=com.widevine.alpha
#KODIPROP:inputstream.adaptive.license_key=https://....?drm-type=widevine
https://something....

I believe shaka player (open source) can play these

Numbers are changed obviously

Thanks

No files or tests are named. Start by locating mpv's playlist parsing and DASH playback entry points, then trace how the m3u properties could carry ClearKey and Widevine license data. Done means the supplied single-key and multi-key ClearKey playlists play their encrypted channels, with the lower-priority Widevine case addressed or explicitly scoped.
