## 📋 Story Requirements
### User Story
**As a** GM using Video View Manager,
**I want to** select custom widths for small and large video widgets in the dock,
**So that** I can optimize the display to match my screen space and table preferences.
### Persona Alignment
- **Primary:** GM (Marcus, Jake) - Needs flexibility to customize video display for different screen configurations and table setups
- **Secondary:** Players - Benefit from consistent, appropriately-sized video feeds that match the GM's layout preferences
### Business Value
This feature extends the Dock Layout System (Epic 5, Story 5-1) by adding granular control over video widget dimensions. It addresses user feedback requesting the ability to customize video tile sizes to better match their specific display needs and table aesthetics.
### Acceptance Criteria (BDD Format)
#### AC-1: Widget Width Settings
**Given** the Video View Manager module is active
**When** the GM opens the Director's Board
**Then** there are dropdown selectors for small and large widget widths
**And** the dropdowns contain the following options: 60px, 80px, 100px, 120px, 150px, 200px
#### AC-2: Default Width Values
**Given** a fresh installation of Video View Manager
**When** no width settings have been configured
**Then** the default width for small widgets is 80px
**And** the default width for large widgets is 120px
#### AC-3: Width Setting Application
**Given** the GM has selected width values in the Director's Board
**When** the GM saves the settings
**Then** all video widgets in the dock are re-rendered with the new widths
**And** small layout variants (vertical-sm, horizontal-sm, mosaic-sm) use the small width setting
**And** large layout variants (vertical-md, horizontal-md, mosaic-md) use the large width setting
#### AC-4: Width Persistence
**Given** the GM has configured custom widget widths
**When** the page is refreshed or the session is restarted
**Then** the widget widths persist and are applied automatically
**And** the dropdowns show the previously selected values
#### AC-5: Per-Layout Width Application
**Given** the GM has selected different widths for small and large
**When** the dock is using a small layout variant
**Then** all video widgets use the small width setting
**And** when the dock is using a large layout variant
**Then** all video widgets use the large width setting
#### AC-6: Real-Time Preview
**Given** the Director's Board is open
**When** the GM changes a width dropdown value
**Then** the video widgets in the dock update in real-time (within 500ms)
**And** no page refresh is required
#### AC-7: Width Setting Validation
**Given** the width dropdown is displayed
**When** the GM selects a width value
**Then** the value is validated as one of the allowed options
**And** invalid values are rejected with a warning message
**And** the previous valid value is retained
#### AC-8: CSS Properly Scoped
**Given** custom widths are applied
**When** the video widgets are rendered
**Then** all width-related CSS is properly scoped under `.sp-participant-item` or `.sp-participant-video`
**And** no unintended CSS conflicts occur with other modules
#### AC-9: Null Safety Throughout
**Given** any DOM query returns null
**When** width application methods are called
**Then** no TypeError is thrown
**And** appropriate warnings are logged to console
---
## 🎯 Functional Requirements
- **FR-33:** Video widget width configuration — The module provides configurable width options for small and large video tiles via world-scoped settings `widgetWidthSm` and `widgetWidthMd`
- **FR-34:** Width selection dropdown in Director's Board — The Director's Board includes dropdown UI controls for selecting video widget widths for both small and large sizes
---

### Technical Implementation
#### Settings Registration (module.js)
```javascript
// World-scoped settings for widget widths
adapter.settings.register("widgetWidthSm", {
scope: "world",
config: false,
type: String,
default: "80",
onChange: () => roleRenderer?.rerenderStrip(),
});
adapter.settings.register("widgetWidthMd", {
scope: "world",
config: false,
type: String,
default: "120",
onChange: () => roleRenderer?.rerenderStrip(),
});
```
#### Director's Board UI (DirectorsBoard.js)
```javascript
// Add to _prepareContext()
const widgetWidthSm = this._adapter.settings?.get?.('widgetWidthSm') ?? '80';
const widgetWidthMd = this._adapter.settings?.get?.('widgetWidthMd') ?? '120';
const WIDTH_OPTIONS = [
{ value: '60', label: '60px' },
{ value: '80', label: '80px' },
{ value: '100', label: '100px' },
{ value: '120', label: '120px' },
{ value: '150', label: '150px' },
{ value: '200', label: '200px' },
];
// Add to context
return {
...base,
widthOptions: WIDTH_OPTIONS,
widgetWidthSm,
widgetWidthMd,
};
// Add handler in _onClickButton()
case 'set-widget-width-sm': this._onSetWidgetWidth(btn.dataset.value, 'sm'); break;
case 'set-widget-width-md': this._onSetWidgetWidth(btn.dataset.value, 'md'); break;
// New method
async _onSetWidgetWidth(value, size) {
if (!value) return;
const settingKey = size === 'sm' ? 'widgetWidthSm' : 'widgetWidthMd';
try {
await this._adapter.settings?.set?.(settingKey, value);
} catch (err) {
console.error('[ScryingPool] Failed to set widget width:', err);
}
if (this.rendered) this.render({ force: true });
}
```
#### ScryingPoolStrip Context (ScryingPoolStrip.js)
```javascript
// Add to _prepareContext()
const widgetWidthSm = this._adapter.settings?.get?.('widgetWidthSm') ?? '80';
const widgetWidthMd = this._adapter.settings?.get?.('widgetWidthMd') ?? '120';
const dockLayout = this.context?.dockLayout ?? 'vertical-sm';
const isLarge = dockLayout.endsWith('-md');
const effectiveWidth = isLarge ? widgetWidthMd : widgetWidthSm;
return {
...base,
widgetWidth: effectiveWidth,
isLarge,
};
```
#### Template Updates (directors-board.hbs)
```handlebars
{{!-- In settings panel --}}
<div class="sp-settings-group">
<label>Video Widget Widths</label>
<div class="sp-settings-row">
<span>Small:</span>
<select data-action="set-widget-width-sm">
{{#each widthOptions}}
<option value="{{this.value}}" {{../widgetWidthSm == this.value ? "selected" : ""}}>
{{this.label}}
</option>
{{/each}}
</select>
</div>
<div class="sp-settings-row">
<span>Large:</span>
<select data-action="set-widget-width-md">
{{#each widthOptions}}
<option value="{{this.value}}" {{../widgetWidthMd == this.value ? "selected" : ""}}>
{{this.label}}
</option>
{{/each}}
</select>
</div>
</div>
```
#### CSS Updates (components/_roster-strip.less)
```less
// Apply width to participant items
.sp-participant-item {
width: var(--widget-width, 80px);
min-width: var(--widget-width, 80px);
// Or use inline style from template
// width: {{widgetWidth}}px;
// min-width: {{widgetWidth}}px;
}
// Ensure video elements fill the width
.sp-participant-video {
width: 100%;
height: 100%;
}
```

## 📚 Developer Context Section
### What the Developer MUST Know
#### 1. Settings Pattern
**Critical:** This story uses the established world-scoped setting pattern from previous stories.
**Pattern:**
```javascript
adapter.settings.register("settingName", {
scope: "world",
config: false,
type: String,
default: "defaultValue",
onChange: () => callback(),
});
```
**Do NOT:**
- Use client-scoped settings (width should be consistent for all users)
- Forget the onChange callback (strips won't update automatically)
- Use numeric type (stored as string to maintain precision)
**DO:**
- Always provide sensible defaults
- Always include onChange callback to trigger UI updates
- Use string type for pixel values to avoid type issues
#### 2. Dock Layout Integration
This feature **extends** the existing Dock Layout System (FR-29-30), not replaces it.
**Integration Points:**
- Width settings are independent of layout direction (vertical/horizontal/mosaic)
- Width settings depend on size variant (sm/md)
- Layout selection (FR-29) and width selection (FR-33) work together
**Flow:**
1. GM selects layout direction + size (e.g., vertical-md)
2. System determines if layout is small or large variant
3. System applies corresponding width setting (widgetWidthSm or widgetWidthMd)
4. Strip re-renders with new layout AND width
#### 3. Real-Time Update Pattern
**Critical:** Width changes must update video widgets in real-time without page refresh.
**Pattern:**
```javascript
onChange: () => roleRenderer?.rerenderStrip()
```
**Why:**
- Provides immediate visual feedback
- Matches existing pattern from Dock Layout System (FR-29)
- Expected by users from modern web applications
**DO:**
- Use onChange callback on settings registration
- Call rerenderStrip() when width changes
- Ensure rerender includes updated width in context
#### 4. Dropdown UI Pattern
**Critical:** Follow existing Director's Board UI patterns for consistency.
**Pattern:**
- Use `<select>` element with `data-action` attribute
- Include all options with value and label
- Show current value as selected
- Handle change in `_onClickButton` or similar method
**Reference:** See existing dock layout selector in DirectorsBoard.js (FR-29 implementation)
#### 5. CSS Scoping Pattern
**Critical:** All CSS must be properly scoped to avoid conflicts.
**Pattern:**
```less
.sp-participant-item {
// Scoped styles here
}
```
**Why:**
- Prevents conflicts with other modules
- Follows FoundryVTT best practices
- Maintains modular CSS architecture
**DO:**
- Use `.sp-*` prefix for all custom classes
- Avoid global selectors
- Use inline styles from template if dynamic values needed

## 📖 Technical Information
### FoundryVTT Settings API
**Methods Used:**
```javascript
game.settings.register(module, key, config)
game.settings.get(module, key)
game.settings.set(module, key, value)
```
**Config Options:**
- `scope`: "world" (GM-controlled) or "client" (user-specific)
- `config`: true (show in settings UI) or false (hidden, programmatic only)
- `type`: String, Number, Boolean, Object
- `default`: Default value
- `onChange`: Callback function when value changes
### CSS Styling Approach
**Recommended:** Use template variables for dynamic widths
```handlebars
<div class="sp-participant-item" style="width: {{widgetWidth}}px; min-width: {{widgetWidth}}px;">
```
**Alternative:** Use CSS custom properties
```javascript
// In _prepareContext
document.documentElement.style.setProperty('--widget-width', `${width}px`);
// In CSS
.sp-participant-item {
width: var(--widget-width, 80px);
}
```

## ✅ What Went Well
### 🎯 Major Successes
#### 1. Architecture Decision: Full Replacement Over Hooking
**Decision:** Replace Foundry's native AV dock completely rather than hooking into it.
**Implementation:**
- Foundry's AV dock (`#av`) completely hidden via CSS
- Foundry's camera views (`.camera-view`) completely hidden via CSS
- Custom ScryingPoolStrip renders all participant video feeds
- Uses actual WebRTC MediaStream objects from `game.webrtc.client.getMediaStreamForUser()`
**Impact:**
- Full control over UI/UX
- Consistent behavior across all AV states
- Enables advanced features (dock layouts, position persistence)
- Better control over rendering pipeline
- Easier to extend and maintain
**Evidence:**
- `styles/scrying-pool.less` lines 77-87: Global hide rules
- `ScryingPoolStrip.js`: Custom video element creation
- All acceptance criteria AC-1 through AC-9 met
**Quote:**
> Morr (Project Lead): "Live testing revealed limitations in the hooking approach. Full replacement gives us the control we need for the dock layout system and position persistence."
---
#### 2. WebRTC API Integration
**Implementation:**
- `FoundryAdapter.probeCapability()` detects `stream-access` mode when `getMediaStreamForUser` is available
- `FoundryAdapter.buildWebRTCSurface()` creates complete WebRTC client API wrapper with 11 methods
- All methods include input validation, null guards, and try-catch error handling
**11 WebRTC Surface Methods:**
1. `getMediaStreamForUser(userId)` — Get MediaStream for a specific user
2. `getConnectedUsers()` — Get array of all connected user IDs
3. `getLevelsStreamForUser(userId)` — Get volume monitoring stream
4. `isAudioEnabled()` — Check current user audio status
5. `isVideoEnabled()` — Check current user video status
6. `toggleAudio(enable)` — Enable/disable audio
7. `toggleVideo(enable)` — Enable/disable video
8. `toggleBroadcast(enable)` — Enable/disable broadcast
9. `setUserVideo(userId, videoElement)` — Set video element for user
10. `disableTrack(userId)` — Legacy: disable video track
11. `enableTrack(userId)` — Legacy: enable video track
**Impact:**
- Full access to FoundryVTT v14 WebRTC API
- Safe, validated access patterns
- Backward compatible with non-standard AV backends
**Evidence:**
- `FoundryAdapter.js` lines 351-450: Complete WebRTC surface implementation
- All methods have JSDoc documentation
- All methods have try-catch with console.error logging
---
#### 3. Comprehensive Video Lifecycle Management
**Implementation:**
- `ScryingPoolStrip._attachVideoStreams()` — Attaches video elements to all participant items
- `ScryingPoolStrip._attachVideoStream()` — Creates and configures individual video elements
- `ScryingPoolStrip._cleanupVideoStreams()` — Properly cleans up all video elements and MediaStream tracks
- `ScryingPoolStrip._refreshVideoStreams()` — Reattaches all streams when needed
**Video Element Configuration:**
```javascript
videoElement.srcObject = stream; // Actual MediaStream
videoElement.autoplay = true;
videoElement.playsInline = true;
videoElement.muted = (userId === game.userId); // Mute self
videoElement.classList.add('sp-participant-video__element');
```
**Cleanup Pattern:**
```javascript
// Stop all tracks in the stream
if (videoEl.srcObject instanceof MediaStream) {
videoEl.srcObject.getTracks().forEach(track => track.stop());
}
videoEl.srcObject = null;
videoEl.remove();
```
**Impact:**
- No memory leaks from MediaStream tracks
- Proper resource cleanup when strip closes
- Prevents orphaned video elements
**Evidence:**
- `ScryingPoolStrip.js` lines 401-420: Complete cleanup implementation
- `ScryingPoolStrip.js` lines 520-620: Video attachment lifecycle
---
#### 4. Migration Path for Existing Installations
**Implementation:**
- Automatic detection of deprecated `webrtcMode` values (`'track-disable'`, `'css-fallback'`)
- Migration to new capability-based mode (`'stream-access'`)
- Fresh capability probe for existing installations
**Migration Logic:**
```javascript
const currentWebRtcMode = adapter.settings.get(FoundryAdapter.SETTING_WEBRTC_MODE);
const isDeprecatedMode = currentWebRtcMode === 'track-disable'
|| currentWebRtcMode === 'css-fallback';
const outcome = isDeprecatedMode
? FoundryAdapter.probeCapability(game.webrtc)
: currentWebRtcMode || FoundryAdapter.probeCapability(game.webrtc);
adapter.settings?.set(FoundryAdapter.SETTING_WEBRTC_MODE, outcome);
```
**Impact:**
- Zero breaking changes for existing users
- Automatic upgrade to new functionality
- Smooth transition path
**Evidence:**
- `module.js` lines 229-237: Complete migration logic
- AC-8: Migration path acceptance criterion met
---
#### 5. CSS Architecture
**Implementation:**
- Global overrides hide Foundry's native AV dock
- Properly scoped Video View Manager styles
- Responsive video container styling
- Avatar fallback when no stream available
**CSS Structure:**
```css
/* Global overrides - hide Foundry AV dock */
#av { display: none !important; }
.camera-view { display: none !important; }
/* Video container */
.sp-participant-video {
position: absolute;
inset: 0;
width: 100%;
height: 100%;

## ⚠️ Challenges & Growth Areas
### 1. Architecture Decision Complexity
**Challenge:** Deciding between Full Replacement vs Overlay vs Track Disable architecture.
**Context:**
- **Overlay Approach:** Overlay on Foundry's AV tiles - abandoned because WebRTC tracks can't be disabled to save bandwidth
- **Track Disable Approach:** Disable video tracks cosmetically - abandoned because doesn't reduce bandwidth
- **CSS Fallback Approach:** CSS-only hiding - abandoned because doesn't provide actual video
- **Full Replacement Approach:** Selected - completely hides Foundry's dock and creates custom video elements
**Root Cause:** Each approach had trade-offs that needed careful evaluation.
**Resolution:** Full Replacement architecture chosen for maximum control and flexibility.
**Lesson Learned:** Architecture decisions require thorough analysis of trade-offs. The Full Replacement approach, while more work initially, provides the foundation for future features.
**Action Item:** Document architecture decision rationale in ADR (Architecture Decision Record) for future reference.
---
### 2. FoundryVTT v14 API Discovery
**Challenge:** Confirming the existence and capabilities of `game.webrtc.client.getMediaStreamForUser()`.
**Context:**
- Needed to verify API exists in FoundryVTT v14
- Needed to understand all available methods
- Needed to test actual MediaStream access
**Root Cause:** FoundryVTT WebRTC API documentation is limited; required code inspection.
**Resolution:**
- Found API in `/foundry/foundryv14/resources/app/client/av/clients/simplepeer.mjs`
- Confirmed 11 available methods
- Verified API returns actual MediaStream objects
**Lesson Learned:** When working with new FoundryVTT APIs, direct code inspection is often necessary. The API provides robust stream access capabilities.
**Action Item:** Maintain a reference document of FoundryVTT v14 WebRTC API methods for future development.
---
### 3. MediaStream Resource Management
**Challenge:** Properly managing MediaStream lifecycle to prevent memory leaks.
**Context:**
- MediaStream objects and their tracks consume memory
- Must be stopped and cleaned up when no longer needed
- Must handle cases where streams become unavailable
**Root Cause:** WebRTC MediaStreams are heavy resources that require explicit cleanup.
**Resolution:** Implemented comprehensive cleanup in `_cleanupVideoStreams()`:
- Stop all tracks in each MediaStream
- Null out srcObject references
- Remove video elements from DOM
**Lesson Learned:** Always pair resource acquisition with cleanup. The cleanup pattern established here should be reused for any future WebRTC work.
**Action Item:** Create a utility class for MediaStream lifecycle management if more WebRTC features are added.
---
### 4. Cross-Module Compatibility
**Challenge:** Ensuring Video View Manager's full AV dock replacement doesn't conflict with other modules.
**Context:**
- Other modules may patch AV-related hooks
- Must properly chain hooks to avoid conflicts
- Must handle cases where other modules expect native AV dock to be present
**Root Cause:** Full dock replacement is an invasive change that affects the entire AV system.
**Resolution:**
- Proper hook chaining implemented
- CSS hide rules are specific and targeted
- Module gracefully handles missing native AV elements
**Deferred Consideration:** Test with popular FoundryVTT modules (Monk's Hotbar, Token Action HUD, etc.) to verify compatibility.
**Action Item:** Add integration testing with other popular modules to CI pipeline.
---
### 5. !important CSS Overrides
**Challenge:** Using `!important` in global CSS overrides may override other modules' styles.
**Context:**
- `#av { display: none !important; }`
- `.camera-view { display: none !important; }`
**Root Cause:** Need to ensure Foundry's AV dock is completely hidden, even if other styles try to show it.
**Current State:** Deferred from code review - accepted as necessary for full replacement architecture.
**Consideration:** The `!important` flag is necessary here to ensure the native dock stays hidden. However, this could potentially conflict with other modules that also try to style these elements.
**Action Item:** Monitor for compatibility issues with other AV-related modules. Consider alternative approach if conflicts arise.
