This project provides you a simple command to easily download a League of Legends replay game which still in process (ingame), like lolking or op.gg feature. Replays are stored in your server and can be watched at any time.
All download files can be decoded to parse them. It uses the library : https://github.com/EloGank/lol-replay-downloader

• A ready-to-use CLI
• A ready-to-use Virtual Machine, using Vagrant (automatic installation)
• A built-in replay decoder for each files (chunks & keyframes)
• An asynchronous system, allow to download some replays at the same time and save the log into the replay folder
• Download previous data if you start the download process after the start of the game
• Can wait for the start of the game if you start the download process too early
• Fully configurable

You have two ways to install the repository. First, with a Virtual Machine, optional but recommended on Windows OS, and the second way, manually (but less than 2 minutes, I swear).

If you want to install/try this project with a Virtual Machine and avoid the installation process if you haven't yet a PHP environment, read the virtual machine documentation. It will take you only one minute.

If you want to install/try this project on a Windows system, I advice you to choose the Virtual Machine installation process. This project hasn't been tested on a Windows system.

Simply clone this project and run the composer install command. If you don't know what is Composer, read the dedicated documentation.

See all the available configurations here.

This project provides you an unique command : php console elogank:replay:download

Usage:
 elogank:replay:download [--async] [--override] region game_id encryption_key

Arguments:
 region                The game region
 game_id               The game id
 encryption_key        The game encryption key

Options:
 --async               The replay download will be asynchronous
 --override            If exists, the replay folder will be override
 --help (-h)           Display this help message.
 --quiet (-q)          Do not output any message.
 --verbose (-v|vv|vvv) Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug.
 --version (-V)        Display this application version.
 --ansi                Force ANSI output.
 --no-ansi             Disable ANSI output.
 --no-interaction (-n) Do not ask any interactive question.

Example of output :

Retrieve metas...                       OK
Validate game criterias...              OK
Retrieve last infos...                  OK
Download all previous chunks (28)...    OK
Download all previous keyframes (12)... OK

Download current game data :
Downloading chunk       29              OK
Downloading keyframe    13              OK
Downloading chunk       ...

To get the region, is pretty easy : just look at the file config/config.yml, all region servers are listed. For example, if you play on the EUW server, just use the region EUW1.

For the game id and the encryption key, it's a few harder. Indeed, the official Riot API doesn't provide yet an API to retrieve this data.
To get it, you have to use an unofficial API, like this : https://github.com/EloGank/lol-php-api, please see the route game.retrieve_in_progress_spectator_game_info. Note that using other route is not allowed, by the new Riot Terms of Use (see "Important notes" below).

For testing purpose, you can simply go to spectating websites like lolnexus, click on "Spectate" button on a game, and you'll have the region, game id & encryption key in the command line to launch the game, see the end of the line :

"C:\Riot Games\League of Legends\RADS\solutions\lol_game_client_sln\releases\0.0.1.xx\deploy\League of Legends.exe" "8394" "LoLLauncher.exe" "" "spectator SERVER_ADDRESS ENCRYPTION_KEY GAME_ID REGION"

Example :

"C:\Riot Games\League of Legends\RADS\solutions\lol_game_client_sln\releases\0.0.1.68\deploy\League of Legends.exe" "8394" "LoLLauncher.exe" "" "spectator 185.40.64.163:80 nwP+BEYqHgk4sElnU2uRogoxGPUw1dzE 1234567890 EUW1"

So, you can run the command :

php console elogank:replay:download EUW1 1234567890 nwP+BEYqHgk4sElnU2uRogoxGPUw1dzE

A LoLNexus PHP parser exists here : https://github.com/EloGank/lol-replay-downloader/blob/master/examples/utils/LoLNexusParser.php

Usage is simple : you juste have to select the region by calling LoLNexusParser::parseRandom($regionId) or LoLNexusParser::parsePlayer($regionId, $playerName) methods and it will bring you all parameters for running a command by calling LoLNexusParser::getRegion(), LoLNexusParser::getGameId() or LoLNexusParser::getEncryptionKey() methods.

Example is available here : https://github.com/EloGank/lol-replay-downloader/blob/master/examples/download-replay.php#L32-L48

According to the new Riot Terms of Use (1st October 2014), using data from another source of their official API is not allowed. So using data by parsing decoded files is not allowed. This project provides a way to decode file only for teaching purpose.

You can download a full game only if you start the download process before the ~8th ingame minute. Otherwise, you won't have the start of the game.

Feel free to open an issue, fork this project or suggest an awesome new feature in the issue tracker.
