### Description

Hi, i would like to request a plugin for [USTVnow](https://www.ustvnow.com/). They offer [free](https://www.ustvnow.com/register.php?sub=7) access to [7 US TV Channels](https://support.ustvnow.com/hc/en-us/articles/214145143-What-plans-channels-are-available-) and paid access to 30 channels, [some in HD](https://support.ustvnow.com/hc/en-us/articles/214145203-What-USTVnow-channels-are-available-in-HD-on-the-paid-plans-).

Access-URL:
http://m.ustvnow.com/iphone (iStuff)
http://www.ustvnow.com/gtv/ (SmartTVs)
http://watch.ustvnow.com/guide (Webbrowsers)

The direct links are javascript-obfuscated and i can't see deep-links to the programs

They use various protocols, including HLS and RTMP, **but HLS access only works for 30 days on the free account**. HLS seems to offer a bit more quality (even on the SD-Only free account)

There are already several projects in python that can produce an m3u playlist (the urls are only valid for about 30mins):

https://github.com/mathsgrinds/ustvnow-iptv-m3u-playlist (HLS playlist, worked a week ago)
https://github.com/guilleiguaran/ustvnow-m3u-server (RTMP playlist, stopped working about a year ago).

A choice of the protocol(s) would be great (as mentioned, HLS only works for 30 days for free), but i would be happy with anything that "just works" :)

Thanks :D
