Quick Reference: Component Props & UI Overrides

New: UI override parity now extends across Webinar and Chat layouts, unifying customization for every MediaSFU interface.

Every primary MediaSFU UI export—MediasfuGeneric, MediasfuBroadcast, MediasfuConference, MediasfuWebinar, and MediasfuChat—now ships with a consistent prop surface and a powerful uiOverrides input, so you can bend the bundled experience to match your product without losing MediaSFU's hardened real-time logic.

Shared component inputs (applies to every MediaSFU UI component)

| Input | Type | Default | What it does | | --- | --- | --- | --- | | PrejoinPage | ComponentType | WelcomePage | Swap in a custom pre-join experience. Receives unified pre-join options so you can add branding, legal copy, or warm-up flows. | | localLink | string | "" | Point the SDK at your self-hosted MediaSFU server. Leave empty when using MediaSFU Cloud. | | connectMediaSFU | boolean | true | Toggle automatic socket/WebRTC connections. Set to false when you only need the UI shell. | | credentials | { apiUserName: string; apiKey: string } | { apiUserName: "", apiKey: "" } | Supply cloud credentials without hard-coding them elsewhere. | | useLocalUIMode | boolean | false | Run the interface in local/demo mode with no remote signaling. | | seedData, useSeed | SeedData, boolean | {}, false | Pre-populate the UI for demos, snapshot tests, or onboarding tours. | | imgSrc | string | https://mediasfu.com/images/logo192.png | Default artwork used across pre-join and modal flows. | | sourceParameters | Record<string, unknown> | undefined | Shared helper bag (media devices, participant helpers, layout handlers). Pair with updateSourceParameters to mirror the SDK's internal utilities. | | updateSourceParameters | EventEmitter | undefined | Receive the latest helper bundle so you can bridge MediaSFU logic into your own components. | | returnUI | boolean | true | When false, mount the logic only—a perfect stepping stone to a fully bespoke interface. | | noUIPreJoinOptions | CreateJoinRoomParameters \| JoinLocalEventRoomParameters | undefined | Feed pre-join data when returnUI is false and you want to bypass the on-screen wizard. | | joinRoom, createRoom | Function | undefined | Inject your own networking layers for joining or creating rooms. | | customComponent | ComponentType | undefined | Replace the entire UI while retaining transports, sockets, and helpers. | | customVideoCard, customAudioCard, customMiniCard | ComponentType | undefined | Override participant card renders to add metadata, CTAs, or badges. | | [customStyles] | Record<string, any> | undefined | Apply inline styles to the root wrapper (dashboards, split views, etc.). | | [uiOverrides] | MediasfuUICustomOverrides | undefined | Targeted component/function overrides described below. |

Power combo: Set returnUI="false" to run MediaSFU logic headless, capture helpers via updateSourceParameters output, and selectively bring UI pieces back with uiOverrides. That gives you progressive migration with minimal code churn.

import type { MediasfuUICustomOverrides } from 'mediasfu-angular';

const overrides: MediasfuUICustomOverrides = { /* ... */ };

Bring the types into your project to unlock full IntelliSense for every override slot.

Custom UI Playbook

Use a toggle-driven "playbook" component to experiment with MediaSFU's customization layers. Flip a couple of booleans and you can watch the SDK jump between prebuilt layouts, headless logic, or a fully bespoke workspace driven by customComponent.

What the playbook demonstrates

• Connection presets: toggle connectionScenario between cloud, hybrid, or ce to swap credentials, local links, and connection modes in one place.
• Experience selector: the selectedExperience switch renders MediasfuGeneric, MediasfuBroadcast, MediasfuWebinar, MediasfuConference, or MediasfuChat without touching the rest of your stack.
• UI strategy flags: booleans like showPrebuiltUI, enableFullCustomUI, and enableNoUIPreJoin demonstrate how to run the MediaSFU logic with or without the bundled UI.
• Layered overrides: toggles enable the custom video/audio/mini cards, drop-in uiOverrides for layout and modal surfaces, container styling, and backend proxy helpers.
• Custom workspace demo: a customComponent receives live MediaSFU helpers so you can build dashboards, CRM surfaces, or any bespoke host interface.
• Debug panel & helpers: optional JSON panel exposes the updateSourceParameters payload so you can see exactly what to wire into your own components.

Try it quickly

@Component({
  selector: 'app-custom-ui-playbook',
  template: `
    <ng-container [ngSwitch]="selectedExperience">
      <app-mediasfu-generic *ngSwitchCase="'generic'"
        [credentials]="currentPreset.credentials"
        [localLink]="currentPreset.localLink"
        [connectMediaSFU]="currentPreset.connectMediaSFU"
        [returnUI]="showPrebuiltUI"
        [uiOverrides]="overrides"
        [customStyles]="containerStyles">
      </app-mediasfu-generic>
      
      <app-mediasfu-broadcast *ngSwitchCase="'broadcast'"
        [credentials]="currentPreset.credentials"
        [localLink]="currentPreset.localLink"
        [connectMediaSFU]="currentPreset.connectMediaSFU"
        [returnUI]="showPrebuiltUI"
        [uiOverrides]="overrides">
      </app-mediasfu-broadcast>
      
      <!-- Similar for webinar, conference, chat -->
    </ng-container>
  `
})
export class CustomUIPlaybookComponent {
  connectionScenario: 'cloud' | 'hybrid' | 'ce' = 'cloud';
  selectedExperience: 'generic' | 'broadcast' | 'webinar' | 'conference' | 'chat' = 'generic';
  showPrebuiltUI = true;
  enableFullCustomUI = false;

  connectionPresets = {
    cloud: { 
      credentials: { apiUserName: 'demo', apiKey: 'demo' }, 
      localLink: '', 
      connectMediaSFU: true 
    },
    hybrid: { 
      credentials: { apiUserName: 'demo', apiKey: 'demo' }, 
      localLink: 'http://localhost:3000', 
      connectMediaSFU: true 
    },
    ce: { 
      credentials: undefined, 
      localLink: 'http://localhost:3000', 
      connectMediaSFU: false 
    },
  };

  get currentPreset() {
    return this.connectionPresets[this.connectionScenario];
  }

  overrides: MediasfuUICustomOverrides = {
    mainContainer: this.enableFullCustomUI ? {
      component: CustomMainContainerComponent
    } : undefined,
  };

  containerStyles = {
    background: 'linear-gradient(135deg, #0f172a, #1e3a8a)',
    minHeight: '100vh'
  };
}

Toggle the configuration values at the top of the playbook and watch the UI reconfigure instantly. It's the fastest path to understand MediaSFU's override surface before you fold the patterns into your production entrypoint.

Passing custom props and UI overrides

Use the same playbook to validate bespoke cards, override bundles, and fully custom workspaces before you move them into production code:

@Component({
  selector: 'app-advanced-playbook',
  template: `
    <app-mediasfu-generic
      [credentials]="credentials"
      [customVideoCard]="videoCard"
      [customAudioCard]="audioCard"
      [customMiniCard]="miniCard"
      [customComponent]="enableFullCustomUI ? customWorkspace : undefined"
      [customStyles]="containerStyles"
      [uiOverrides]="uiOverrides">
    </app-mediasfu-generic>
  `
})
export class AdvancedPlaybookComponent {
  credentials = { apiUserName: 'demo', apiKey: 'demo' };
  enableFullCustomUI = false;

  // Custom card components with themed styling
  videoCard = VideoCardComponent; // Pass component class
  audioCard = AudioCardComponent;
  miniCard = MiniCardComponent;
  customWorkspace = CustomWorkspaceComponent;

  containerStyles = {
    background: '#0f172a',
    borderRadius: '32px',
    overflow: 'hidden'
  };

  uiOverrides: MediasfuUICustomOverrides = {
    mainContainer: {
      component: CustomMainContainerComponent
    },
    menuModal: {
      component: CustomMenuModalComponent
    },
    consumerResume: {
      wrap: (original) => async (params) => {
        const startedAt = performance.now();
        const result = await original(params);
        console.log('consumer_resume', {
          durationMs: performance.now() - startedAt,
          consumerId: params?.consumer?.id,
        });
        return result;
      },
    },
  };
}

Because the playbook surfaces updateSourceParameters, you can also log or snapshot the helper bundle (getParticipantMedia, toggleMenuModal, showAlert, and more) to ensure your custom UI always receives the hooks it expects.

uiOverrides input — override keys at a glance

Each key accepts a CustomComponentOverride<Props> or CustomFunctionOverride<Fn> object with optional component and wrap fields. You can fully replace the default implementation or wrap it while forwarding props.

Layout & control surfaces

| Key | Default component | Typical use | | --- | --- | --- | | mainContainer | MainContainerComponent | Inject theming providers or dashboard layouts. | | mainAspect | MainAspectComponent | Tune how the main region splits space. | | mainScreen | MainScreenComponent | Orchestrate hero video + gallery interplay. | | mainGrid | MainGridComponent | Modify layout or layering of primary participants. | | subAspect | SubAspectComponent | Restyle fixed control strips in webinar/conference modes. | | otherGrid | OtherGridComponent | Change presentation of off-stage attendees. | | flexibleGrid, flexibleGridAlt | FlexibleGrid | Implement AI-driven or branded array layouts. | | flexibleVideo | FlexibleVideo | Add captions, watermarks, or overlays to highlighted speakers. | | audioGrid | AudioGrid | Customise audio-only attendee presentation. | | pagination | Pagination | Introduce infinite scroll or auto-cycling carousels. | | controlButtons | ControlButtonsComponent | Rebrand the primary action bar. | | controlButtonsAlt | ControlButtonsAltComponent | Control secondary button clusters. | | controlButtonsTouch | ControlButtonsComponentTouch | Deliver mobile-first controls (used heavily by MediasfuChat). |

Example: swap the chat modal and theme the controls

import { Component } from '@angular/core';
import { MediasfuGeneric } from 'mediasfu-angular';
import { MyChatModalComponent } from './ui/my-chat-modal.component';
import { MyControlsComponent } from './ui/my-controls.component';

@Component({
  selector: 'app-my-meeting',
  template: `
    <app-mediasfu-generic
      [credentials]="credentials"
      [uiOverrides]="uiOverrides">
    </app-mediasfu-generic>
  `
})
export class MyMeetingComponent {
  credentials = { apiUserName: 'your-api-user', apiKey: 'your-api-key' };

  uiOverrides = {
    messagesModal: {
      component: MyChatModalComponent,
    },
    controlButtons: {
      component: MyControlsComponent,
    },
  };
}

Example: wrap a MediaSFU helper instead of replacing it

import { Component } from '@angular/core';
import { MediasfuConference } from 'mediasfu-angular';

@Component({
  selector: 'app-analytics-meeting',
  template: `
    <app-mediasfu-conference
      [credentials]="credentials"
      [uiOverrides]="uiOverrides">
    </app-mediasfu-conference>
  `
})
export class AnalyticsMeetingComponent {
  credentials = { apiUserName: 'your-api-user', apiKey: 'your-api-key' };

  uiOverrides = {
    consumerResume: {
      wrap: (original) => async (params) => {
        const startedAt = performance.now();
        const result = await original(params);
        
        // Send analytics
        this.analytics.track('consumer_resume', {
          durationMs: performance.now() - startedAt,
          consumerId: params?.consumer?.id,
        });
        
        return result;
      },
    },
  };

  constructor(private analytics: AnalyticsService) {}
}

10. Managed Events: Manage events with features to handle abandoned and inactive participants, as well as enforce time and capacity limits.

🆕 New Advanced Media Access

The Angular SDK now includes powerful utility methods for fine-grained control over media devices and participant streams:

getMediaDevicesList - Device Enumeration

Enumerate available cameras and microphones with automatic permission handling:

// Get all available cameras
const cameras = await sourceParameters.getMediaDevicesList('videoinput');
cameras.forEach(camera => {
  console.log(`Camera: ${camera.label} (${camera.deviceId})`);
});

// Get all available microphones
const microphones = await sourceParameters.getMediaDevicesList('audioinput');
microphones.forEach(mic => {
  console.log(`Microphone: ${mic.label} (${mic.deviceId})`);
});

Use Cases:

• Build custom device selection interfaces
• Detect available media hardware
• Switch between multiple cameras/microphones
• Pre-flight device checks before joining

See full documentation and examples →

getParticipantMedia - Stream Access

Retrieve specific participant's video or audio streams by ID or name:

// Get participant video stream by producer ID
const videoStream = await sourceParameters.getParticipantMedia({
  id: 'producer-123',
  kind: 'video'
});

// Get participant audio stream by name
const audioStream = await sourceParameters.getParticipantMedia({
  name: 'John Doe',
  kind: 'audio'
});

// Use the stream (e.g., attach to video element)
if (videoStream) {
  videoElement.srcObject = videoStream;
}

Use Cases:

• Monitor specific participant streams
• Create custom video layouts with individual control
• Build stream recording features
• Implement advanced audio/video processing
• Create picture-in-picture views for specific users

See full documentation and examples →

These utilities enable advanced features like custom device selection interfaces, participant stream monitoring, and dynamic media routing. Both methods are fully integrated with Angular's reactive patterns using RxJS.

Getting Started

This section will guide users through the initial setup and installation of the npm module.

Documentation Reference

For comprehensive documentation on the available methods, components, and functions, please visit mediasfu.com. This resource provides detailed information for this guide and additional documentation.

Installation

Instructions on how to install the module using npm.

1. Add the package to your project

```bash
npm install mediasfu-angular
```

2. Bootstrap Integration

The `mediasfu-angular` package requires Bootstrap for styling. Bootstrap is included by default with the package, so you do not need to install it separately. Ensure that Bootstrap's CSS is correctly added to your project's styles.

1. **Check `angular.json`:**

  Ensure that `node_modules/bootstrap/dist/css/bootstrap.min.css` is listed in the `styles` array of your Angular application's build options.

  ```json
  {
    "projects": {
      "your-app-name": {
        "architect": {
          "build": {
            "options": {
              "styles": [
                "node_modules/bootstrap/dist/css/bootstrap.min.css",
                "src/styles.css"
              ],
              // ... other configurations
            }
          }
        }
      }
    }
  }
  ```

Note: The mediasfu-angular package should handle the Bootstrap's package installation automatically. If it's not present, you may need to add it manually install Bootstrap.

3. Configure MediaSFU's PreJoinPage Requirements

If you intend to use MediaSFU's `PreJoinPage` component, additional configuration is required. You need to provide the `HttpClient` and `CookieService` providers in your application's configuration. These packages should have been installed by default as well else add manually. 

#### Update `app.config.ts`

Add the necessary providers to your `app.config.ts` file. Below is an example configuration:

```typescript
// app.config.ts
import { ApplicationConfig } from '@angular/core';
import { provideZoneChangeDetection } from '@angular/core';
import { provideClientHydration } from '@angular/platform-browser';
import { provideHttpClient } from '@angular/common/http';
import { CookieService } from 'ngx-cookie-service';

export const appConfig: ApplicationConfig = {
  providers: [
    provideZoneChangeDetection({ eventCoalescing: true }),
    provideClientHydration(),
    provideHttpClient(),
    CookieService
  ],
};

```

4. Obtain an API Key (If Required)

You can get your API key by signing up or logging into your account at mediasfu.com.

Self-Hosting MediaSFU

If you plan to self-host MediaSFU or use it without MediaSFU Cloud services, you don't need an API key. You can access the open-source version of MediaSFU from the MediaSFU Open Repository.

This setup allows full flexibility and customization while bypassing the need for cloud-dependent credentials.

Understanding MediaSFU Architecture

Before diving deeper, let's understand how MediaSFU is structured.

The Three-Layer Architecture

┌─────────────────────────────────────────────┐
│        Your Angular Application             │
│  (components, services, business logic)     │
└─────────────────────────────────────────────┘
                    ↓
┌─────────────────────────────────────────────┐

Key Concepts

1. Event Room Types

MediaSFU provides 5 specialized room types, each optimized for specific use cases:

| Room Type | Best For | Key Features | |-----------|----------|--------------| | MediasfuGeneric | General purpose meetings | Flexible layout, all features enabled | | MediasfuBroadcast | Live streaming events | Optimized for one-to-many communication | | MediasfuWebinar | Educational sessions | Presenter focus, Q&A features | | MediasfuConference | Business meetings | Equal participant layout, collaboration tools | | MediasfuChat | Interactive discussions | Chat-first interface, quick connections |

// Choose the right room type for your use case
import { 
  MediasfuWebinar, 
  MediasfuBroadcast, 
  MediasfuConference 
} from 'mediasfu-angular';

@Component({
  // For a webinar
  template: `<app-mediasfu-webinar [credentials]="credentials"></app-mediasfu-webinar>`,
  // For a broadcast
  // template: `<app-mediasfu-broadcast [credentials]="credentials"></app-mediasfu-broadcast>`,
  // For a conference
  // template: `<app-mediasfu-conference [credentials]="credentials"></app-mediasfu-conference>`,
})

2. The Three Usage Modes

MediaSFU offers three progressive levels of customization:

Mode 1: Default UI (Simplest)

Use MediaSFU's complete pre-built interface - perfect for rapid development.

import { Component } from '@angular/core';
import { MediasfuGeneric } from 'mediasfu-angular';

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [MediasfuGeneric],
  template: `<app-mediasfu-generic [credentials]="credentials"></app-mediasfu-generic>`,
})
export class AppComponent {
  credentials = { apiUserName: 'username', apiKey: 'key' };
}

When to use:

• ✅ Prototyping or MVP development
• ✅ Need a production-ready UI quickly
• ✅ Standard video conferencing features are sufficient

Mode 2: Custom UI with MediaSFU Backend (Most Flexible)

Build your own UI while using MediaSFU's powerful backend infrastructure.

import { Component, OnInit } from '@angular/core';
import { MediasfuGeneric } from 'mediasfu-angular';

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [MediasfuGeneric, CommonModule],
  template: `
    <app-mediasfu-generic
      [returnUI]="false"
      [sourceParameters]="sourceParameters"
      [updateSourceParameters]="updateSourceParameters.bind(this)"
      [credentials]="credentials"
      [noUIPreJoinOptions]="preJoinOptions">
    </app-mediasfu-generic>

    <!-- Your custom UI -->
    @if (sourceParameters) {
      <div class="custom-controls">
        <button (click)="toggleVideo()">
          {{ sourceParameters.videoAlreadyOn ? 'Stop Video' : 'Start Video' }}
        </button>
        <button (click)="toggleAudio()">
          {{ sourceParameters.audioAlreadyOn ? 'Mute' : 'Unmute' }}
        </button>
        <button (click)="toggleScreenShare()">
          {{ sourceParameters.screenAlreadyOn ? 'Stop Sharing' : 'Share Screen' }}
        </button>
      </div>
    }
  `,
})
export class AppComponent implements OnInit {
  sourceParameters: any = null;
  credentials = { apiUserName: 'username', apiKey: 'key' };
  preJoinOptions = {
    action: 'create',
    userName: 'Your Name',
    capacity: 50,
    duration: 30,
    eventType: 'conference'
  };

  updateSourceParameters(params: any) {
    this.sourceParameters = params;
  }

  toggleVideo() {
    this.sourceParameters?.clickVideo({ parameters: this.sourceParameters });
  }

  toggleAudio() {
    this.sourceParameters?.clickAudio({ parameters: this.sourceParameters });
  }

  toggleScreenShare() {
    this.sourceParameters?.clickScreenShare({ parameters: this.sourceParameters });
  }
}

When to use:

• ✅ Need complete control over UI/UX
• ✅ Building a custom branded experience
• ✅ Integrating into existing app design

Mode 3: Component Replacement (Balanced)

Replace specific MediaSFU components while keeping the rest of the infrastructure.

import { Component } from '@angular/core';
import { 
  MediasfuGeneric, 
  FlexibleVideo, 
  FlexibleGrid 
} from 'mediasfu-angular';

@Component({
  selector: 'app-custom-main',
  standalone: true,
  imports: [FlexibleVideo, FlexibleGrid, CommonModule],
  template: `
    <div class="custom-layout">
      <!-- Custom header -->
      <div class="custom-header">
        <h1>{{ parameters.roomName }}</h1>
        <span>{{ parameters.participants.length }} participants</span>
      </div>

      <!-- Use MediaSFU's components in your layout -->
      <app-flexible-video
        [customWidth]="windowWidth"
        [customHeight]="600"
        [parameters]="parameters">
      </app-flexible-video>

      <app-flexible-grid
        [customWidth]="windowWidth"
        [customHeight]="400"
        [parameters]="parameters">
      </app-flexible-grid>

      <!-- Custom footer -->
      <div class="custom-footer">
        <button (click)="toggleVideo()">
          {{ parameters.videoAlreadyOn ? 'Stop Video' : 'Start Video' }}
        </button>
      </div>
    </div>
  `,
  styles: [`
    .custom-layout { 
      display: flex; 
      flex-direction: column; 
      height: 100vh; 
    }
    .custom-header { 
      padding: 20px; 
      background: #1976d2; 
      color: white; 
    }
  `]
})
export class CustomMainComponent {
  parameters: any;
  windowWidth = window.innerWidth;

  toggleVideo() {
    this.parameters?.clickVideo({ parameters: this.parameters });
  }
}

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [MediasfuGeneric],
  template: `
    <app-mediasfu-generic
      [credentials]="credentials"
      [PrejoinPage]="PreJoinPage"
      [customComponent]="CustomMainComponent">
    </app-mediasfu-generic>
  `,
})
export class AppComponent {
  PreJoinPage = PreJoinPage;
  CustomMainComponent = CustomMainComponent;
  credentials = { apiUserName: 'username', apiKey: 'key' };
}

When to use:

• ✅ Need custom main interface but want to keep MediaSFU's components
• ✅ Partial customization with minimal effort
• ✅ Want to maintain MediaSFU's functionality while customizing layout

3. Parameters: Your Control Center

The sourceParameters object (or parameters in custom components) is your gateway to all MediaSFU functionality. It's powered by RxJS BehaviorSubjects for reactive state management:

// Available in sourceParameters or parameters object
{
  // Media Controls (Methods)
  clickVideo: (options) => {},
  clickAudio: (options) => {},
  clickScreenShare: (options) => {},
  
  // Room State (BehaviorSubject values)
  roomName: 'meeting-123',
  participants: [...],
  allVideoStreams: [...],
  allAudioStreams: [...],
  
  // UI State (BehaviorSubject values)
  videoAlreadyOn: false,
  audioAlreadyOn: false,
  screenAlreadyOn: false,
  
  // Update Functions (BehaviorSubject next())
  updateVideoAlreadyOn: (value) => {},
  updateAudioAlreadyOn: (value) => {},
  
  // And 200+ more properties and methods...
}

Access patterns:

// In Mode 1 (Default UI): Parameters are managed internally
// You don't need to access them directly

// In Mode 2 (Custom UI): Access via sourceParameters
sourceParameters?.clickVideo({ parameters: sourceParameters });

// In Mode 3 (Component Replacement): Passed to your custom component
@Component({
  template: `<button (click)="toggleVideo()">Toggle</button>`
})
export class CustomComponent {
  @Input() parameters: any;
  
  toggleVideo() {
    this.parameters.clickVideo({ parameters: this.parameters });
  }
}

// Subscribing to reactive state changes
sourceParameters.participants.subscribe((participants) => {
  console.log('Participants updated:', participants);
});

Core Concepts & Components

Now that you understand the architecture, let's explore the building blocks.

1. Display Components: Building Your Video Layout

MediaSFU provides powerful components for organizing and displaying media streams.

Primary Layout Components

FlexibleVideo - Main video display area

import { FlexibleVideo } from 'mediasfu-angular';

@Component({
  template: `
    <app-flexible-video
      [customWidth]="windowWidth"
      [customHeight]="600"
      [parameters]="parameters">
    </app-flexible-video>
  `
})

• Automatically handles main presenter or screen share
• Smooth transitions between different video sources
• Responsive sizing

FlexibleGrid - Participant grid layout

import { FlexibleGrid } from 'mediasfu-angular';

@Component({
  template: `
    <app-flexible-grid
      [customWidth]="windowWidth"
      [customHeight]="800"
      [parameters]="parameters">
    </app-flexible-grid>
  `
})

• Intelligent grid sizing (2x2, 3x3, 4x4, etc.)
• Pagination for large participant lists
• Automatic reflow on window resize

AudioGrid - Audio-only participants

import { AudioGrid } from 'mediasfu-angular';

@Component({
  template: `<app-audio-grid [parameters]="parameters"></app-audio-grid>`
})

• Displays participants without video
• Audio level indicators
• Compact layout for efficiency

Container Components

| Component | Purpose | Use Case | |-----------|---------|----------| | MainContainerComponent | Primary content wrapper | Wraps all main content areas | | MainAspectComponent | Aspect ratio container | Maintains proper video proportions | | MainScreenComponent | Screen layout manager | Organizes screen regions | | SubAspectComponent | Secondary content container | For picture-in-picture, sidebars |

Example: Building a custom layout

import { Component } from '@angular/core';
import {
  MainContainerComponent,
  FlexibleVideo,
  FlexibleGrid,
  AudioGrid
} from 'mediasfu-angular';

@Component({
  selector: 'app-custom-layout',
  standalone: true,
  imports: [
    MainContainerComponent,
    FlexibleVideo,
    FlexibleGrid,
    AudioGrid,
    CommonModule
  ],
  template: `
    <app-main-container-component>
      <div class="layout-container">
        <!-- Main video area -->
        <div class="main-video">
          <app-flexible-video
            [customWidth]="windowWidth"
            [customHeight]="windowHeight * 0.6"
            [parameters]="parameters">
          </app-flexible-video>
        </div>
        
        <!-- Participant grid -->
        <div class="participant-grid">
          <app-flexible-grid
            [customWidth]="windowWidth"
            [customHeight]="windowHeight * 0.3"
            [parameters]="parameters">
          </app-flexible-grid>
        </div>
        
        <!-- Audio-only participants -->
        <div class="audio-participants">
          <app-audio-grid [parameters]="parameters"></app-audio-grid>
        </div>
      </div>
    </app-main-container-component>
  `,
  styles: [`
    .layout-container {
      display: flex;
      flex-direction: column;
      height: 100vh;
    }
    .main-video { flex: 3; }
    .participant-grid { flex: 2; }
    .audio-participants { height: 80px; }
  `]
})
export class CustomLayoutComponent {
  @Input() parameters: any;
  windowWidth = window.innerWidth;
  windowHeight = window.innerHeight;
}

2. Control Components: User Interactions

ControlButtonsComponent - Standard control bar

import { ControlButtonsComponent } from 'mediasfu-angular';

@Component({
  template: `
    <app-control-buttons-component
      [parameters]="parameters"
      [position]="'bottom'">
    </app-control-buttons-component>
  `
})

Includes: mute, video, screenshare, participants, chat, settings, etc.

ControlButtonsAltComponent - Alternative layout

import { ControlButtonsAltComponent } from 'mediasfu-angular';

@Component({
  template: `
    <app-control-buttons-alt-component
      [parameters]="parameters"
      [position]="'top'">
    </app-control-buttons-alt-component>
  `
})

Different button arrangement optimized for specific layouts.

ControlButtonsComponentTouch - Touch-optimized controls

import { ControlButtonsComponentTouch } from 'mediasfu-angular';

@Component({
  template: `
    <app-control-buttons-component-touch
      [parameters]="parameters">
    </app-control-buttons-component-touch>
  `
})

Floating action buttons optimized for mobile/tablet interfaces.

3. Modal Components: Feature Interfaces

MediaSFU includes modals for various features:

import {
  ParticipantsModal,
  MessagesModal,
  SettingsModal,
  DisplaySettingsModal,
  RecordingModal,
  PollModal,
  BreakoutRoomsModal
} from 'mediasfu-angular';

// These are automatically rendered when enabled
// Control their visibility via parameters
parameters.updateIsParticipantsModalVisible.next(true);
parameters.updateIsMessagesModalVisible.next(true);
parameters.updateIsSettingsModalVisible.next(true);

Available modals:

• ParticipantsModal - Participant list management
• MessagesModal - Chat interface
• SettingsModal - Event and room settings
• DisplaySettingsModal - Layout and display options
• RecordingModal - Recording controls and settings
• PollModal - Create and manage polls
• BreakoutRoomsModal - Breakout room management

Example: Programmatically showing modals

@Component({
  selector: 'app-custom-toolbar',
  template: `
    <div class="custom-toolbar">
      <button (click)="showParticipants()">
        Show Participants ({{ participantCount }})
      </button>
      
      <button (click)="openChat()">
        Open Chat
      </button>
      
      <button (click)="createPoll()">
        Create Poll
      </button>
    </div>
  `
})
export class CustomToolbarComponent {
  @Input() parameters: any;

  get participantCount() {
    return this.parameters?.participants?.length || 0;
  }

  showParticipants() {
    this.parameters?.updateIsParticipantsModalVisible.next(true);
  }

  openChat() {
    this.parameters?.updateIsMessagesModalVisible.next(true);
  }

  createPoll() {
    this.parameters?.launchPoll?.launchPoll({ parameters: this.parameters });
  }
}

parameters.switchVideoAlt({ parameters });

// Switch to specific camera by ID
const cameras = await parameters.getMediaDevicesList('videoinput');
parameters.switchUserVideo({
  videoPreference: cameras[1].deviceId,
  parameters
});

// Get current video state
const isVideoOn = parameters.videoAlreadyOn;

// Subscribe to video state changes (RxJS)
parameters.videoAlreadyOn.subscribe((isOn: boolean) => {
  console.log('Video is now:', isOn ? 'ON' : 'OFF');
});

// Update video state programmatically
parameters.updateVideoAlreadyOn.next(true);

Audio Control

parameters.switchUserAudio({
  audioPreference: microphones[1].deviceId,
  parameters
});

// Get current audio state
const isAudioOn = parameters.audioAlreadyOn;
const hasHostPermission = parameters.micAction; // Host approval status

// Subscribe to audio state changes
parameters.audioAlreadyOn.subscribe((isOn: boolean) => {
  console.log('Audio is now:', isOn ? 'ON' : 'OFF');
});

// Mute/unmute specific participant (host only)
parameters.controlMedia({

});

Media Device and Stream Utility Methods

Get Available Media Devices

// Get available cameras
const cameras = await parameters.getMediaDevicesList('videoinput');
cameras.forEach(camera => {
  console.log(`Camera: ${camera.label} (${camera.deviceId})`);
});

// Get available microphones
const microphones = await parameters.getMediaDevicesList('audioinput');
microphones.forEach(mic => {
  console.log(`Microphone: ${mic.label} (${mic.deviceId})`);
});

// Request to unmute participant (sends request)
parameters.requestScreenShare({ parameters });

Chat & Messaging Methods

// Send a group message
parameters.sendMessage({
  message: 'Hello everyone!',
  type: 'group',
  parameters
});

// Send direct message
parameters.sendMessage({
  message: 'Private message',
