### Custom Initialization (init.js)

Source: https://mpv.io/manual/stable

Details how to customize the JavaScript environment for all scripts using an `init.js` file.

```APIDOC
## Custom initialization

### Description
mpv allows for custom initialization of the JavaScript environment before any script is loaded. This is achieved by placing an `init.js` file in the root of the mpv configuration directory. Code within this file can modify the environment for all subsequent scripts.

### Location
- The file should be named `init.js`.
- It must be located at the root of the mpv configuration directory (e.g., `~/.config/mpv/init.js`).

### Functionality
- Code in `init.js` runs after the JavaScript environment is set up but before any user scripts are loaded.
- It can be used to modify global settings, add paths to `mp.module_paths`, or define global utility functions.

### Example
To add a custom directory to the module search path for all scripts:
```javascript
// ~/.config/mpv/init.js
mp.module_paths.push('/path/to/my/custom/modules');
```

### Important Note on `mp.module_paths`
- Always use `mp.module_paths.push(path)` to add new search paths.
- **Do not** use `mp.module_paths = [path]` as this will overwrite all existing paths, potentially breaking default module loading behavior (like `<script-dir>/modules`).

### Behavior
- The custom `init.js` file is ignored if mpv is invoked with the `--no-config` command-line option.

### Historical Note
- Before mpv version 0.34, the initialization file was named `.init.js` (with a leading dot) and located in the same directory.

```

--------------------------------

### A-B Looping Points

Source: https://mpv.io/manual/stable

Sets specific start and end points for looping within a file.

```APIDOC
## --ab-loop-a=<time>, --ab-loop-b=<time>

### Description
Sets loop points. When playback passes the `b` timestamp, it will seek to the `a` timestamp. Seeking past the `b` point does not loop.

If `a` is after `b`, the behavior is as if the points were given in the correct order, and the player will seek to `b` after crossing through `a`.

If either option is set to `no` (or unset), looping is disabled.

### Note
The loop-points can be adjusted at runtime using the corresponding properties or the `ab-loop` command.
```
