WidevineProxy2 failing to detect 1080p stream in a certain provider

[1v0live]

Since WidevineProxy2 is my first choice for this type of content, i find it a little strange that it fails to detect the 1080p stream while other software can: https://mega.nz/file/20I3SbYB#a50CroV7eQ9ZZmpJ36OAeAGvI5ZnuinQQZZnQ1iwvPQ
This modified version of YDL-UI downloads the videos at 1080p. Try this one for yourself: https://www.rtp.pt/play/p16527/e919961/a-costa-dos-murmurios

Now what i don't know is if YDL-UI is doing some ultrafast upscale behind the scenes of if WidevineProxy2 can't really detect the stream, which i find it strange since it detects it in other websites.

all you have to do is to change _lo.mp4 to _hi.mp4

Wow that is interesting. Great eye-opener. Thank you!

What if "hi" does not work? (another case)

[sesamap159]

To get 1080p, you just need to enter this as the default:

-sv Best -sa Best

-sv = select-video 1080p
-sa = select-audio mp4a in 128 kbps

Sorry but that is not working. It just goes automatically to 720p. And when i put the "hi" it gives a Bad Gateway error.

How do i know if 720p is really the maximum available of if there is an hidden higher resolution?
