Twitch.tv extension v0.0.2 by Stefan Sundin
https://gist.github.com/stefansundin/c200324149bb00001fef5a252a120fc2

The only thing that this extension does is to act as a helper to seek to the
correct time when you open a twitch.tv url that contains a timestamp.
You must have the playlist parser installed as well!

Usage:
1. Install the playlist parser: https://addons.videolan.org/p/1167220/
2. Install this file in the lua/extensions/ directory:
- On Windows: %APPDATA%/vlc/lua/extensions/
- On Mac: $HOME/Library/Application Support/org.videolan.vlc/lua/extensions/
- On Linux: ~/.local/share/vlc/lua/extensions/
- On Linux (snap package): ~/snap/vlc/current/.local/share/vlc/lua/extensions/
To install the addon for all users, put the file here instead:
- On Windows: C:/Program Files/VideoLAN/VLC/lua/extensions/
- On Mac: /Applications/VLC.app/Contents/MacOS/share/lua/extensions/
- On Linux: /usr/lib/vlc/lua/extensions/
- On Linux (snap package): /snap/vlc/current/usr/lib/vlc/lua/extensions/
3. Open VLC and activate the extension via the menu.
   NOTE: You must do this every time you restart VLC, as far as I know there is
         no way for the extension to activate itself. :(
         There is no feedback indicating that the extension was activated.
4. Open a twitch.tv url with a timestamp using "Open Network Stream..."

Download and install with one command on Mac:
curl -o "$HOME/Library/Application Support/org.videolan.vlc/lua/extensions/twitch-extension.lua" https://gist.githubusercontent.com/stefansundin/c200324149bb00001fef5a252a120fc2/raw/twitch-extension.lua

Download and install with one command on Linux:
curl -o ~/.local/share/vlc/lua/extensions/twitch-extension.lua https://gist.githubusercontent.com/stefansundin/c200324149bb00001fef5a252a120fc2/raw/twitch-extension.lua

Twitch.tv playlist parser v0.3.1 by Stefan Sundin
https://gist.github.com/stefansundin/c200324149bb00001fef5a252a120fc2
https://www.opencode.net/stefansundin/twitch.lua
https://addons.videolan.org/p/1167220/

Once installed, you can open a twitch.tv url using "Open Network Stream..."
Features:
- Load a channel and watch live: https://www.twitch.tv/speedgaming
- Load an archived video: https://www.twitch.tv/videos/113837699
- Load a clip: https://clips.twitch.tv/AmazonianKnottyLapwingSwiftRage

This playlist parser utilizes a proxy since v0.3.0 since Twitch completely shut down their old API.
VLC can't make POST requests so there isn't another way to work around the problem.
For information about the proxy please go to https://github.com/stefansundin/media-resolver
You can run the proxy on your own computer but you'll have to edit the proxy_host variable below.

Installation:
Put the file in the lua/playlist/ directory:
- On Windows: %APPDATA%/vlc/lua/playlist/
- On Mac: $HOME/Library/Application Support/org.videolan.vlc/lua/playlist/
- On Linux: ~/.local/share/vlc/lua/playlist/
- On Linux (snap package): ~/snap/vlc/current/.local/share/vlc/lua/playlist/
To install the addon for all users, put the file here instead:
- On Windows: C:/Program Files/VideoLAN/VLC/lua/playlist/
- On Mac: /Applications/VLC.app/Contents/MacOS/share/lua/playlist/
- On Linux: /usr/lib/vlc/lua/playlist/
- On Linux (snap package): /snap/vlc/current/usr/lib/vlc/lua/playlist/

On Linux, you can download and install with the following command:
mkdir -p ~/.local/share/vlc/lua/playlist/; curl -o ~/.local/share/vlc/lua/playlist/twitch.lua https://gist.githubusercontent.com/stefansundin/c200324149bb00001fef5a252a120fc2/raw/twitch.lua

On Mac, you can download and install with the following command:
mkdir -p "$HOME/Library/Application Support/org.videolan.vlc/lua/playlist/"; curl -o "$HOME/Library/Application Support/org.videolan.vlc/lua/playlist/twitch.lua" https://gist.githubusercontent.com/stefansundin/c200324149bb00001fef5a252a120fc2/raw/twitch.lua

Changelog:
- v0.3.1: Added back support for clips.
- v0.3.0: Twitch finally completely shut down their old API. Because VLC scripts can't easily make POST requests it currently requires a proxy to work. To simplify things I removed all features besides loading a live channel and archived videos. I could potentially add back some of the features in the future but I am unsure if I have the will to do it.
- v0.2.3: Fix loading the list of a channel's old videos. Remove support for clips as it is broken and not easy to fix.
- v0.2.2: Fix 1080p on archived videos. Add audio only stream.
- v0.2.1: Skip live videos when loading /<channel>/videos.
- v0.2.0: Support new URLs. Most things seem to be working again.
- v0.1.3: Minor fix that prevented me from running this on Ubuntu 18.04 (snap package).
- v0.1.2: Support for /directory/game/<name>/videos/<type>.
- v0.1.1: Support for /<channel>/clips, /directory/game/<name>/clips. Add ability to load the next page.
- v0.1.0: Rewrote almost the whole thing. Support for /communities/<name>, /directory/game/<name>, /<channel>/videos/, collections.
- v0.0.6: Support new go.twitch.tv urls (beta site).
- v0.0.5: Fix a couple of minor issues.
- v0.0.4: Support new twitch.tv/videos/ urls.
- v0.0.3: Support for Twitch Clips.
- v0.0.2: You can now pick the stream quality you want. The twitch URL will expand to multiple playlist items.

-- Set this variable to true to only add the first stream:
local only_add_one_stream = false

-- You can change the order of the streams using this variable:
local preferred_streams = {}
-- Examples:
-- local preferred_streams = { "1080p", "720p" }
-- local preferred_streams = { "360p", "160p", "720p60", "720p" }
-- local preferred_streams = { "Audio Only" }
--
-- Technical note:
-- The sort algorithm is not stable. This means that streams not listed here may become jumbled by the sorting (the sorting only happens if this list has entries in it).

-- You can modify this variable to only include certain streams:
local allowed_streams = {}
-- Examples:
-- local allowed_streams = { "1080p" }
-- local allowed_streams = { "360p", "720p" }
-- local allowed_streams = { "360p" }
-- It does a substring match, so you can use "1080p" to allow both "1080p" and "1080p60".

-- You can modify this variable to skip certain streams:
local skipped_streams = {}
-- Examples:
-- local skipped_streams = { "1080p", "Audio Only" }
-- It does a substring match, so you can use "1080p" to block both "1080p" and "1080p60".

Thanks. Works great.

Hello, how can I change the resolution? broadcast or video quality at 720p or 480p

@Khomchyk1992 I have pushed some updates to the script to allow the resolution to be picked more easily. I have NOT released this on addons.videolan.org yet, so for now please download the twitch.lua file manually here.

You have to edit a few variables in the code. They are named only_add_one_stream, preferred_streams, allowed_streams, and skipped_streams. Hopefully they should let you do what you want.

Please write a comment here if they solve your problem, and if you have any feedback. Thanks.

Thank you very much, set your value, everything works.
