Build Requirements

• Visual Studio 2022

Libraries:

• Poco

Compiling

See one of build workflows for more detailed steps

1. Integrate vcpkg with Visual Studio
2. Build project in Visual Studio (It has to be x64 Release build, it's the only one configuration setup, but please check before doing that)

Installing

• Rename original loc_x64_f.dll to loc_x64_f_o.dll
• Copy loc_x64_f.dll file from either the latest build in GitHub Releases or from Release folder if you compiled it yourself

Configuration

You can change the default behavior of the hook by creating config in supported format where the game .exe is

The following formats are supported:

• .properties - properties file (in order to use it, create QuantumBreak.properties where the game executable is)
• .ini - initialization file (in order to use it, create QuantumBreak.ini where the game executable is)
• .xml - XML file (in order to use it, create QuantumBreak.xml where the game executable is)

In the config, you can set following values (dot seperates section and key)

Key	Description	Allowed Values	Default Value
Logger.ShowConsole	Show hook log in console	Boolean	false
Logger.SaveToLogFile	Save hook log to file	Boolean	false
Logger.LogFile	Path to where save log file	String	QuantumStreamer.log
Logger.LogLevel_Core	Changes how detailed Core logging is	Poco::Message::Priority	6 (PRIO_INFORMATION)
Logger.LogLevel_Network	Changes how detailed Network logging is (HTTP Requests/Responses)	Poco::Message::Priority	6 (PRIO_INFORMATION)
Logger.LogLevel_VideoList	Changes how detailed Video List subsystem logging is	Poco::Message::Priority	6 (PRIO_INFORMATION)
Logger.LogLevel_OfflineStreaming	Changes how detailed Offline Streaming subsystem logging is	Poco::Message::Priority	6 (PRIO_INFORMATION)
Logger.LogLevel_SubtitleOverride	Changes how detailed Subtitle Override subsystem logging is	Poco::Message::Priority	6 (PRIO_INFORMATION)
Server.EpisodesPath	Path to where episodes data are located	String	./videos/episodes
Server.MaxQueued	Max queued HTTP requests	Integer	100
Server.MaxThreads	Max threads (HTTP server)	Integer	Logical CPU count or 2 if failed
Server.OfflineMode	Disable online streaming, episodes stored locally will continue to work	Boolean	false
Server.Port	Port for HTTP server (game also have to point to this port), if 0 will use random unused port	Unsigned short	0
Server.VideoListPath	Path to original, unmodified ./data/videoList.rmdj file	String	./data/videoList_original.rmdj
Subtitles.ClosedCaptioning	Show closed captions in subtitles	Boolean	false
Subtitles.MusicNotes	Show music notes in subtitles	Boolean	true
VideoList.PatchFile	Patch ./data/videoList.rmdj to point to server on startup	Boolean	true

The default config should work for most of the users, but if you have special requirements you can change above settings.

Example config that will disable online streaming and enables Closed Captioning:

[Server]
OfflineMode=false
[Subtitles]
ClosedCaptioning=true

Usage

Initially, after installing the hook, with default config - nothing should change in-game. Quantum Streamer on game launch will try to load Server.VideoListPath, after that hook will scan Server.EpisodesPath directory for the locally stored episodes and/or captions_overrides.

VideoList loaded by game (data/videoList.rmdj) has to point to the Quantum Streamer server, by default Quantum Streamer will patch this file, but you can disable this behaviour by setting VideoList.PatchFile to false, but then, you have to patch that file manually - for that, you can use QuantumFetcher tool.

Each episode data is expected to be in dedicated episode directory (e.g. ./videos/episodes/J1A-X1-X2 is where hook will look for episode J1A-X1-X2 (assuming Server.EpisodesPath is not changed)) Local episodes are expected to be in ISM Smooth Stream format:

*.ism (Server Manifest) should at least define clientManifestRelativePath in head section which should reference filename/relative path for client manifest file. All media files referenced in the Server Manifest will be loaded (if media file exist)

Additionally, SubRip (.srt) files which contain _captions in their filename will be loaded, after that hook will replace captions in specific track (e.g. enus_captions.srt will override enus_captions track) with the ones from the file, allowing you to translate or edit captions in the live action.
