Sentence Mining Game Audio Trim Helper

This project automates the recording of game sentence audio to help with Anki Card Creation.

This allows us to create cards from texthooker/yomitan, and automatically get screenshot and sentence audio from the game we are playing.

Features:

• Voice Activity Detection: Automatically cuts the end of the clip to the exact moment the voice ended.
• OBS Replay Buffer: Constantly records the last X seconds of gameplay.
• Clipboard Interaction: Automatically monitors the clipboard for dialogue events.
• Websocket Listening: Listens to a websocket uri for text-events from stuff like Agent/Textractor.
• Hotkey Automation: Single hotkey to trigger video recording, screenshot, and transcription.
• 1-Click Card Creation: Monitors anki for new cards from Yomitan, and automatically gets audio from games.

Prerequisites

• Python 3.11+
• OBS Studio

Quick Disclaimer/Troubleshooting

Every game/hook is different, so it's really impossible that any script can get it perfect everytime. Also OBS is sometimes a bit finnicky if running for too long. If the audio timing is off, please first try some troubleshooting steps before making an issue:

• Try Restarting OBS
• Make sure your hook is the best you can find. (Preferrably it gives you the text RIGHT when the voiceline starts)
• Try Adjusting Offset Configuration in config.toml to better match your situation. (i.e. if the hook is late, add a negative beginning offset)
• Try using "Trim beginning" in VAD settings.

Setup Troubleshooting

Just going to continuously update this with issues that I have helped users with. Look here first if you have issues setting it up.

• Make sure folder_to_watch is the same as your recordings path in OBS. It defaults to ~/Videos, but I recommend setting it to ~/Videos/OBS.
• if it says something about a missing library, attempt to run pip install -r requirements.txt again
• If using clipboard, make sure agent/textractor sending to clipboard is enabled.

1. Setting Up OBS 60-Second Replay Buffer

1. Install OBS Studio: Download and install OBS from here.
2. Enable Replay Buffer:
   1. Open OBS and navigate to Settings → Output → Replay Buffer.
   2. Enable the Replay Buffer and set the duration to 60 seconds, this can be lower, or higher, but 60 works for a very simple setup.
3. Set a Hotkey for the Replay Buffer:
   1. Go to Settings → Hotkeys and find Save Replay Buffer.
   2. Assign a hotkey for saving the replay.
4. Set Scene/Source. I recommend using "Game Capture" with "Capture Audio" Enabled. And then mute Desktop/microphone
   1. If "Game Capture" Does not work, use "Window Capture".
   2. I recommend having a Scene PER Game, with the name of the scene labeled as the game, this makes it easier for the script to know (with a config option) what game you are playing.
5. In Output Settings, set "Recording Format" to mkv, and "Audio Encoder" to Opus. Alternative Settings may be supported at a later date.
6. Set up obs websocket (HIGHLY RECOMMENDED see #5)
   1. Can allow my script to automatically start (and stop) the replay buffer, as well as automatically add audio/screenshot to card created from yomi.

Here are the Settings I use in OBS. Make sure the recordings folder is the same as the "folder_to_watch" in the config.

2. Configuring the App.

Configuration GUI

The GameSentenceMiner project now includes a graphical interface to simplify configuration. With default values already set, this GUI lets you adjust settings as needed. Here’s how to get started:

Running the Configuration GUI

To open the GUI, you have two options:

1. Directly Run the Script: Open a terminal in your project directory and enter: \\bash python config_gui.py \\
2. Console Command: You can also type config in the console if you’re already running the main script.

Default Settings and Customization

The GUI loads with default values for each setting, so if you’re just getting started, you may only need to change stuff in the "path" config. If you make changes, remember to click Save Settings to apply them. Please take a second to look through the config to see what is available, there is a lot of extra functionality hidden behind config options.

2. Configuring config.toml DEPRECATED Only used if running an older version.

I redid the config parsing cause config.py is not ideal, especially when distributing a script via git.

Your config.toml file allows you to configure key settings for the automation process, file paths, and other behavior. Here are the configurable options:

Duplicate/rename config_EXAMPLE.toml to get started

# Path configurations

3. Install Requirements

If you know what you are doing, do this in a venv, but I'm not going to explain that here.

pip install -r requirements.txt

4. Installing FFmpeg

To run this script, you will need to have FFmpeg installed. If you don't have FFmpeg installed on your system, you can easily install it via Chocolatey (Preferred), or install it yourself and ensure it's in the PATH.

Step-by-Step Instructions:

1. First, ensure you have Chocolatey installed. If you don't have it installed, follow the instructions on the Chocolatey installation page or run the following command in an elevated PowerShell window (run as Administrator):

   Set-ExecutionPolicy Bypass -Scope Process -Force; `
   [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; `
   iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))

2. Once Chocolatey is installed, open a new PowerShell or Command Prompt window (with administrator rights).

3. Run the following command to install FFmpeg:

   choco install ffmpeg

4. After the installation is complete, verify that FFmpeg is correctly installed by running the following command:

   ffmpeg -version

   If the installation was successful, you should see the version information for FFmpeg.

Now you're ready to use FFmpeg in the script!

5. One Click Card Creation

This is the flagship feature of this script, so here is a section explaining it. It is possible to do full 1-click card creation with this tool + Yomitan. The relevant settings are located in Features and OBS section in the config.

Demo: https://www.youtube.com/watch?v=9dmmXO2CGNw

Screenshots to help with setup:

6. Example Process

1. Start game
2. Hook Game with Agent (or textractor) with clipboard enabled
3. start script: python main.py
   1. Create Anki Card with target word (through a texthooker page/Yomitan)
   2. (If full-auto-mode not on) Trigger Hotkey to record replay buffer
4. When finished gaming, end script

Once the hotkey is triggered:

1. OBS will save the last X seconds of gameplay.
2. The Python script will trim the audio based on last clipboard event, and the end of voiceline detected in Vosk if enabled.
3. Will attempt to update the LAST anki card created.

How to Update the Script

Updater (Preferred)

There is now an Update script included! running python update.py in the directory will attempt to update your scripts to the latest release. If you have made changes to any of the files, they will be safely backed up before being replaced.

---

Manual

To ensure you always have the latest version of this script, you can use git pull to update your local repository with the latest changes from the remote repository.

Step-by-Step Instructions

1. Open your terminal and navigate to the directory where you cloned the repository:

   cd path/to/script

2. Run the following command to fetch and integrate the latest changes:

   git pull origin main

   • origin refers to the remote repository from which you cloned the code.
   • main refers to the main branch of the repository. If your default branch has a different name ( e.g., master or dev), replace main with that branch name.

3. The git pull command will download and apply any updates from the remote repository to your local version.

Example:

$ cd path/to/script
$ git pull origin master
