We shouldn't store the user's password. We can call /core/accounts/{accountId}/authentication_token after login with username and password and store the resulting token to login with.

Kodi Matrix has switched to Python 3 (Hooray!!!)

This will require some rewrites on how unicode is handled.
I have a preliminary version that I haven't committed for Matrix that I will merge in when Matrix hits release.

I get the following errors when trying to start the VRV addon. I have not been able to get it up running yet. I haven't looked through the entire log below is just what I thought might be important and be causing the crash. I would love to get this working for me a media center without VRV is just not worth it.
Thanks in advance for any help!

EDIT:Sorry this was on a Raspberry Pi 3 b Kodi L8.0.1 LibreElec 6.0.1

As it is currently Hi Dive subtitles are not being formatted properly.

Over the weekend it seems, VRV changed the signing mechanism/policy for the API; mainly, instead of one set of keys/parameters, there's three. As a result, this completely breaks the plugin (except for watchlist retrieval). I've already started (and mostly finished I think) work on implementing the code to read in the key sets and apply them based on which url is being accessed, but it needs to be tested.

when i start the plugin it errors and the log says

how can i fix this?

Could I use your code to make a VRV API for Node.JS?
Thanks in advance!
