### Rust OBS Plugin Example: TestModule and TestSource

Source: https://github.com/bennetthardwick/rust-obs-plugins/blob/master/README.md

This Rust code demonstrates the creation of a basic OBS plugin using the `obs-wrapper` crate. It defines a `TestModule` that implements the `Module` trait and a `TestSource` struct implementing `Sourceable`, `GetNameSource`, and `Module` to register a new source with OBS.

```rust
use obs_wrapper::
    // Everything required for modules
    prelude::*,
    // Everything required for creating a source
    source::*,
    // Macro for registering modules
    obs_register_module,
    // Macro for creating strings
    obs_string;

// The module that will handle creating the source.
struct TestModule {
    context: ModuleRef
}

// The source that will be shown inside OBS.
struct TestSource;

// Implement the Sourceable trait for TestSource, this is required for each source.
// It allows you to specify the source ID and type.
impl Sourceable for TestSource {
    fn get_id() -> ObsString {
        obs_string!("test_source")
    }

    fn get_type() -> SourceType {
        SourceType::Filter
    }

    fn create(create: &mut CreatableSourceContext<Self>, source: SourceContext) -> Self {
        Self
    }
}

// Allow OBS to show a name for the source
impl GetNameSource for TestSource {
    fn get_name() -> ObsString {
        obs_string!("Test Source")
    }
}

// Implement the Module trait for TestModule. This will handle the creation of the source and
// has some methods for telling OBS a bit about itself.
impl Module for TestModule {
    fn new(context: ModuleRef) -> Self {
        Self { context }
    }

    fn get_ctx(&self) -> &ModuleRef {
        &self.context
    }

    // Load the module - create all sources, returning true if all went well.
    fn load(&mut self, load_context: &mut LoadContext) -> bool {
        // Create the source
        let source = load_context
            .create_source_builder::<TestSource>()
            // Since GetNameSource is implemented, this method needs to be called to
            // enable it.
            .enable_get_name()
            .build();

        // Tell OBS about the source so that it will show it.
        load_context.register_source(source);

        // Nothing could have gone wrong, so return true.
        true
    }

    fn description() -> ObsString {
        obs_string!("A great test module.")
    }

    fn name() -> ObsString {
        obs_string!("Test Module")
    }

    fn author() -> ObsString {
        obs_string!("Bennett")
    }
}

obs_register_module!(TestModule);

```

### Rust OBS Plugin - Complete Example

Source: https://context7.com/bennetthardwick/rust-obs-plugins/llms.txt

This Rust code defines a complete OBS plugin with a custom source. It includes module registration, source creation, property management, and video rendering hooks. Dependencies include the 'obs-wrapper' crate. It takes color and intensity values as input for rendering.

```rust
use obs_wrapper::{
    graphics::*,

### Build and Install scroll-focus-filter with Cargo

Source: https://github.com/bennetthardwick/rust-obs-plugins/blob/master/plugins/scroll-focus-filter/README.md

This code snippet demonstrates how to build the scroll-focus-filter plugin using Cargo and then create a symbolic link to the compiled plugin for OBS. This allows for easier updates without manual copying.

```bash
cd rust-obs-plugins
cargo build -p scroll-focus-filter --release
# Create a symlink to the plugin so that you don't need to copy when rebuilding, you
# could alternatively run `sudo cp ./target/release/scrollfocus.so /usr/lib/obs-plugins/`
sudo ln -s $(pwd)/target/release/libscrollfocus.so /usr/lib/obs-plugins/libscrollfocus.so
```

### Manage OBS Settings with DataObj in Rust

Source: https://context7.com/bennetthardwick/rust-obs-plugins/llms.txt

Demonstrates how to create, set, get, and manipulate OBS settings data using the DataObj structure. It covers setting default values, reading values with type inference, creating DataObj from JSON and files, exporting to JSON, removing keys, clearing settings, and handling nested objects.

```rust
use obs_wrapper::{data::*, obs_string};
use std::borrow::Cow;

fn work_with_settings() {
    // Create new data object
    let mut settings = DataObj::new();

    // Set default values
    settings.set_default(obs_string!("width"), 1920_i64);
    settings.set_default(obs_string!("height"), 1080_i64);
    settings.set_default(obs_string!("fps"), 30.0_f64);
    settings.set_default(obs_string!("enabled"), true);
    settings.set_default(obs_string!("name"), obs_string!("Default"));

    // Read values with type inference
    let width: Option<i64> = settings.get(obs_string!("width"));
    let height: Option<u32> = settings.get(obs_string!("height"));
    let fps: Option<f64> = settings.get(obs_string!("fps"));
    let enabled: Option<bool> = settings.get(obs_string!("enabled"));
    let name: Option<Cow<str>> = settings.get(obs_string!("name"));

    println!("Resolution: {}x{} @ {} fps",
             width.unwrap_or(1920),
             height.unwrap_or(1080),
             fps.unwrap_or(30.0));

    // Create from JSON
    let json_data = r#"{"bitrate": 6000, "codec": "h264", "enabled": true}"#;
    if let Some(config) = DataObj::from_json(json_data) {
        let bitrate: Option<i64> = config.get(obs_string!("bitrate"));
        let codec: Option<Cow<str>> = config.get(obs_string!("codec"));
        println!("Codec: {}, Bitrate: {}",
                 codec.unwrap().as_ref(),
                 bitrate.unwrap());
    }

    // Load from file
    if let Some(mut file_settings) = DataObj::from_json_file(
        obs_string!("/path/to/config.json"),
        Some(obs_string!(".backup")),
    ) {
        // Export to JSON
        if let Some(json_str) = file_settings.get_json() {
            println!("Settings JSON: {}", json_str);
        }

        // Remove a key
        file_settings.remove(obs_string!("old_setting"));

        // Clear all values
        file_settings.clear();
    }

    // Nested objects
    let mut parent = DataObj::new();
    let mut child = DataObj::new();
    child.set_default(obs_string!("nested_value"), 42_i64);
    parent.set_default(obs_string!("child"), child);

    // Access nested object
    if let Some(nested) = parent.get::<DataObj>(obs_string!("child")) {
        let value: Option<i64> = nested.get(obs_string!("nested_value"));
        println!("Nested value: {}", value.unwrap());
    }
}

### Implement Per-Frame Animation with video_tick in Rust

Source: https://context7.com/bennetthardwick/rust-obs-plugins/llms.txt

Illustrates how to create smooth animations in OBS plugins by utilizing the `video_tick` callback. This example defines an `AnimatedOverlay` struct and implements per-frame updates for position, velocity, and animation progress, including easing functions and target position changes.

```rust
use obs_wrapper::{graphics::Vec2, obs_string, source::*};

struct AnimatedOverlay {
    position: Vec2,
    target_position: Vec2,
    velocity: Vec2,
    animation_progress: f32,
    animation_duration: f32,
}

impl Sourceable for AnimatedOverlay {
    fn get_id() -> ObsString {
        obs_string!("animated_overlay")
    }

    fn get_type() -> SourceType {
        SourceType::Filter
    }

    fn create(_ctx: &mut CreatableSourceContext<Self>, _source: SourceRef) -> Self {
        Self {
            position: Vec2::new(0.0, 0.0),
            target_position: Vec2::new(0.5, 0.5),
            velocity: Vec2::new(0.0, 0.0),
            animation_progress: 0.0,
            animation_duration: 1.0,
        }
    }
}

impl GetNameSource for AnimatedOverlay {
    fn get_name() -> ObsString {
        obs_string!("Animated Overlay")
    }
}

// Called every video frame
impl VideoTickSource for AnimatedOverlay {
    fn video_tick(&mut self, seconds: f32) {
        // Update animation progress
        self.animation_progress = (self.animation_progress + seconds / self.animation_duration).min(1.0);

        // Smooth step easing function
        let t = self.animation_progress;
        let smoothed = t * t * (3.0 - 2.0 * t);

        // Interpolate position
        let dx = self.target_position.x() - self.position.x();
        let dy = self.target_position.y() - self.position.y();

        self.position.set(
            self.position.x() + dx * smoothed,
            self.position.y() + dy * smoothed,
        );

        // Update velocity for physics-based effects
        self.velocity.set(dx / seconds, dy / seconds);

        // Reset animation if complete
        if self.animation_progress >= 1.0 {
            self.animation_progress = 0.0;
            // Set new target position
            self.target_position.set(
                (self.target_position.x() + 0.1) % 1.0,
                (self.target_position.y() + 0.1) % 1.0,
            );
        }
    }
}

```

### Integrate Rust Logging with OBS

Source: https://context7.com/bennetthardwick/rust-obs-plugins/llms.txt

This Rust code snippet demonstrates how to integrate Rust's 'log' crate with OBS's logging system using the 'obs_wrapper::log::Logger'. It shows how to initialize the logger with a specified log level and use standard logging macros (trace, debug, info, warn, error). Messages will appear in OBS log files and the console.

```rust
use log::{debug, error, info, trace, warn};
use obs_wrapper::log::Logger;

fn setup_logging() {
    // Initialize logger with OBS
    Logger::new()
        .with_max_level(log::LevelFilter::Debug)
        .init()
        .expect("Failed to initialize logger");

    // Use standard Rust logging macros
    trace!("This is a trace message");
    debug!("Debug information: value = {}", 42);
    info!("Plugin loaded successfully");
    warn!("Warning: deprecated feature used");
    error!("Error occurred: {}", "something went wrong");

    // Messages appear in OBS log files and console
}

```

### Create OBS Plugin Configuration UI Properties in Rust

Source: https://context7.com/bennetthardwick/rust-obs-plugins/llms.txt

This Rust code snippet demonstrates how to build a comprehensive configuration UI for an OBS plugin. It utilizes the `obs-wrapper` library to define various property types, including boolean checkboxes, integer and float sliders, text inputs (default, password, multiline), file and directory pickers, color pickers, font selectors, dropdown lists, and editable lists. These properties allow users to customize plugin settings through the OBS interface.

```rust
use obs_wrapper::{obs_string, properties::*, string::ObsString};

fn create_advanced_properties() -> Properties {
    let mut props = Properties::new();

    // Boolean checkbox
    props.add(
        obs_string!("enable_feature"),
        obs_string!("Enable Advanced Processing"),
        BoolProp,
    );

    // Integer slider
    props.add(
        obs_string!("quality"),
        obs_string!("Quality Level"),
        NumberProp::new_int()
            .with_range(1..=10)
            .with_step(1)
            .with_slider(),
    );

    // Float slider
    props.add(
        obs_string!("opacity"),
        obs_string!("Opacity"),
        NumberProp::new_float(0.01)
            .with_range(0.0..=1.0)
            .with_slider(),
    );

    // Text input
    props.add(
        obs_string!("custom_name"),
        obs_string!("Display Name"),
        TextProp::new(TextType::Default),
    );

    // Password field
    props.add(
        obs_string!("api_key"),
        obs_string!("API Key"),
        TextProp::new(TextType::Password),
    );

    // Multiline text
    props.add(
        obs_string!("description"),
        obs_string!("Description"),
        TextProp::new(TextType::Multiline),
    );

    // File picker
    props.add(
        obs_string!("input_file"),
        obs_string!("Input File"),
        PathProp::new(PathType::File)
            .with_filter(obs_string!("Video Files (*.mp4 *.mov);;All Files (*.*)"))
            .with_default_path(obs_string!("/home/user/videos")),
    );

    // Directory picker
    props.add(
        obs_string!("output_dir"),
        obs_string!("Output Directory"),
        PathProp::new(PathType::Directory),
    );

    // Color picker
    props.add(
        obs_string!("tint_color"),
        obs_string!("Tint Color"),
        ColorProp,
    );

    // Font selector
    props.add(
        obs_string!("text_font"),
        obs_string!("Font"),
        FontProp,
    );

    // Dropdown list (string values)
    let mut mode_list = props.add_list::<ObsString>(
        obs_string!("processing_mode"),
        obs_string!("Processing Mode"),
        false, // not editable
    );
    mode_list.push("Fast", obs_string!("fast"));
    mode_list.push("Balanced", obs_string!("balanced"));
    mode_list.push("Quality", obs_string!("quality"));

    // Dropdown list (integer values)
    let mut size_list = props.add_list::<i64>(
        obs_string!("buffer_size"),
        obs_string!("Buffer Size"),
        false,
    );
    size_list.push("Small (512)", 512);
    size_list.push("Medium (1024)", 1024);
    size_list.push("Large (2048)", 2048);

    // Editable combo box
    let mut preset_list = props.add_list::<ObsString>(
        obs_string!("preset"),
        obs_string!("Preset"),
        true, // editable
    );
    preset_list.push("Default", obs_string!("default"));
    preset_list.push("Custom", obs_string!("custom"));

    // Editable list of files
    props.add(
        obs_string!("file_list"),
        obs_string!("Input Files"),
        EditableListProp::new(EditableListType::Files)
            .with_filter(obs_string!("*.mp4 *.mov")),
    );

    props
}

### Adding obs-wrapper Dependency to Cargo.toml

Source: https://github.com/bennetthardwick/rust-obs-plugins/blob/master/README.md

This TOML snippet shows how to add the `obs-wrapper` crate as a dependency in your `Cargo.toml` file. It specifies the version and configures the library type for creating dynamic link libraries (cdylib), which are required for OBS plugins.

```toml
[dependencies]
obs-wrapper = "0.4"

[lib]
name = "<module-name>"
crate-type = ["cdylib"]

```

### Register OBS Plugin Module in Rust

Source: https://context7.com/bennetthardwick/rust-obs-plugins/llms.txt

Demonstrates how to register a custom plugin module with OBS Studio using the `obs-wrapper` library. This includes defining the module structure, implementing the `Module` trait for initialization, loading, and unloading, and finally registering the module using the `obs_register_module!` macro. It showcases enabling specific capabilities like video rendering and property updates for a source.

```rust
use obs_wrapper::{obs_register_module, obs_string, prelude::*, source::*};

struct MyPluginModule {
    context: ModuleRef,
}

impl Module for MyPluginModule {
    fn new(context: ModuleRef) -> Self {
        Self { context }
    }

    fn get_ctx(&self) -> &ModuleRef {
        &self.context
    }

    fn load(&mut self, load_context: &mut LoadContext) -> bool {
        // Register sources, outputs, etc.
        let source = load_context
            .create_source_builder::<MyVideoFilter>()
            .enable_get_name()
            .enable_video_render()
            .enable_update()
            .enable_get_properties()
            .build();

        load_context.register_source(source);
        true
    }

    fn unload(&mut self) {

### Rust OBS Plugin: Implement Video Filter Source

Source: https://context7.com/bennetthardwick/rust-obs-plugins/llms.txt

This Rust code implements a video filter source for OBS Studio. It leverages the `obs-wrapper` crate to define source behavior, including initialization, settings updates, UI properties, and video rendering logic using custom shaders. Dependencies include the `obs-wrapper` crate and potentially a shader effect file.

```rust
use obs_wrapper::{
    graphics::*,
    media::video::*,
    obs_string,
    prelude::*,
    properties::*,
    source::*
};

struct MyVideoFilter {
    source: SourceRef,
    effect: GraphicsEffect,
    intensity: f64,
    enabled: bool,
}

// Required: Define source ID and type
impl Sourceable for MyVideoFilter {
    fn get_id() -> ObsString {
        obs_string!("my_video_filter")
    }

    fn get_type() -> SourceType {
        SourceType::Filter
    }

    fn create(ctx: &mut CreatableSourceContext<Self>, source: SourceRef) -> Self {
        let settings = &ctx.settings;

        // Load shader effect
        let mut effect = GraphicsEffect::from_effect_string(
            obs_string!(include_str!("./shader.effect")),
            obs_string!("shader.effect"),
        ).expect("Failed to load shader effect");

        let intensity = settings.get(obs_string!("intensity")).unwrap_or(1.0);
        let enabled = settings.get(obs_string!("enabled")).unwrap_or(true);

### Manipulate OBS Sources with Rust

Source: https://context7.com/bennetthardwick/rust-obs-plugins/llms.txt

This Rust code snippet shows how to query and modify properties of OBS sources, including their dimensions, visibility, and state. It also demonstrates media control functions for media sources and how to access target sources for filters. Dependencies include the 'obs_wrapper' crate.

```rust
use obs_wrapper::{media::state::MediaState, obs_string, source::*};

fn manipulate_sources(source: &mut SourceRef) {
    // Query source properties
    let id = source.id();
    let name = source.name().unwrap();
    let source_id = source.source_id().unwrap();
    let width = source.width();
    let height = source.height();
    let base_width = source.get_base_width();
    let base_height = source.get_base_height();

    println!("Source: {} ({})", name.as_str(), source_id.as_str());
    println!("Dimensions: {}x{} (base: {}x{})", width, height, base_width, base_height);

    // Check source state
    let is_showing = source.showing();
    let is_active = source.active();
    let is_enabled = source.enabled();

    println!("State - Showing: {}, Active: {}, Enabled: {}",
             is_showing, is_active, is_enabled);

    // Modify source
    source.set_name("New Source Name");
    source.set_enabled(true);

    // Media control (for media sources)
    source.media_play_pause(false); // Play
    source.media_restart();
    let duration = source.media_duration(); // milliseconds
    let current_time = source.media_time(); // milliseconds
    source.media_set_time(5000); // Seek to 5 seconds

    let state = source.media_state();
    match state {
        MediaState::Playing => println!("Media is playing"),
        MediaState::Paused => println!("Media is paused"),
        MediaState::Stopped => println!("Media is stopped"),
        MediaState::Ended => println!("Media has ended"),
        MediaState::Error => println!("Media error"),
        _ => {}
    }

    source.media_stop();
    source.media_next(); // Next track
    source.media_previous(); // Previous track

    // Access target source (for filters)
    source.do_with_target(|target| {
        let target_width = target.get_base_width();
        let target_height = target.get_base_height();
        println!("Target dimensions: {}x{}", target_width, target_height);
    });
}

### Implement Custom OBS Outputs in Rust

Source: https://context7.com/bennetthardwick/rust-obs-plugins/llms.txt

This Rust code demonstrates how to create a custom output (for streaming or recording) in OBS using the 'obs_wrapper' crate. It defines a struct that implements the 'Outputable', 'GetNameOutput', 'RawVideoOutput', and 'RawAudioOutput' traits, allowing for custom processing of raw video and audio data.

```rust
use obs_wrapper::{
    media::audio::*,
    media::video::*,
    obs_string,
    output::*,
    prelude::*
};

struct CustomOutput {
    width: u32,
    height: u32,
    frame_count: u64,
}

impl Outputable for CustomOutput {
    fn get_id() -> ObsString {
        obs_string!("custom_output")
    }

    fn create(ctx: &mut CreatableOutputContext<Self>) -> Self {
        Self {
            width: 1920,
            height: 1080,
            frame_count: 0,
        }
    }

    fn start(&mut self) -> bool {
        println!("Output started");
        true
    }

    fn stop(&mut self) {
        println!("Output stopped, total frames: {}", self.frame_count);
    }
}

impl GetNameOutput for CustomOutput {
    fn get_name() -> ObsString {
        obs_string!("Custom Output")
    }
}

impl RawVideoOutput for CustomOutput {
    fn raw_video(&mut self, video: &VideoDataSourceContext) {
        self.frame_count += 1;

        // Access raw video data
        let width = video.width();
        let height = video.height();
        let format = video.format();

        // Process frame data based on format
        // Video data available through video context

        if self.frame_count % 100 == 0 {
            println!("Processed {} frames ({}x{}, {:?})",
                     self.frame_count, width, height, format);
        }
    }
}

impl RawAudioOutput for CustomOutput {
    fn raw_audio(&mut self, audio: &mut AudioDataContext) {
        // Access audio samples
        for channel in 0..audio.channels() {
            if let Some(samples) = audio.get_channel_as_mut_slice(channel) {
                // Process audio samples (f32 values)
                for sample in samples.iter() {
                    // Audio processing here
                }
            }
        }
    }
}

### Load and Use HLSL Shader Effect in Rust

Source: https://context7.com/bennetthardwick/rust-obs-plugins/llms.txt

Loads an HLSL shader from a string, retrieves texture and color parameters, configures a sampler, and applies the shader effect to a video source during rendering. This enables custom visual transformations.

```rust
