+# Icon System Update - Liquid Glass Design
+
+## Summary
+Replaced all emoji icons throughout the KVideo application with proper SVG icons following the Liquid Glass design system principles. All icons now use consistent stroke-width, sizing, and styling.
+
+## Changes Made
+
+### 1. Created New Icon Component System
+**File:** `components/ui/Icon.tsx`
+- Created comprehensive icon library with reusable SVG components
+- All icons follow Liquid Glass aesthetic:
+  - Consistent 2px stroke width
+  - Round line caps and joins
+  - Scalable size prop
+  - Proper className support for styling
+- Icons included:
+  - Film (replaces 🎬)
+  - TV (replaces 📺)
+  - Search (replaces 🔍)
+  - List (replaces 📑)
+  - Calendar (replaces 📅)
+  - Globe (replaces 🌍)
+  - Zap (replaces ⚡)
+  - Target (replaces 🎯)
+  - Sparkles (replaces ✨)
+  - Inbox (replaces 📭)
+  - Play (replaces ▶️)
+  - ChevronLeft (replaces ←)
+
+### 2. Updated Main Page (`app/page.tsx`)
+- **Logo**: Replaced 🎬 emoji with favicon.ico image
+- **Search Button**: Replaced 🔍 with `Icons.Search`
+- **Empty Video Poster**: Replaced 🎬 with `Icons.Film`
+- **Calendar Badge**: Replaced 📅 with `Icons.Calendar` + text
+- **Empty State Hero**: Replaced 🎬 with `Icons.Film`
+- **Feature Cards**:
+  - ⚡ → `Icons.Zap`
+  - 🎯 → `Icons.Target`
+  - ✨ → `Icons.Sparkles`
+- **No Results**: Replaced 🔍 with `Icons.Search`
+
+### 3. Updated Player Page (`app/player/page.tsx`)
+- **Back Button**: Replaced ← with `Icons.ChevronLeft`
+- **Empty Player**: Replaced 📺 with `Icons.TV`
+- **Year Badge**: Replaced 📅 with `Icons.Calendar`
+- **Area Badge**: Replaced 🌍 with `Icons.Globe`
+- **Episode List Title**: Replaced 📑 with `Icons.List`
+- **Playing Indicator**: Replaced ▶️ with `Icons.Play`
+- **Empty Episodes**: Replaced 📭 with `Icons.Inbox`
+
+### 4. Updated Layout (`app/layout.tsx`)
+- Added explicit favicon configuration to metadata
+
+## Design Principles Applied
+
+All icons follow the Liquid Glass design system:
+
+1. **Consistent Stroke**: All icons use 2px stroke width
+2. **Round Caps**: strokeLinecap="round" for smooth, soft edges
+3. **Round Joins**: strokeLinejoin="round" for continuous flow
+4. **Scalable**: Size prop allows flexible sizing while maintaining proportions
+5. **Color Aware**: Uses currentColor to inherit text color
+6. **Accessible**: Clear, recognizable shapes with good contrast
+
+## Icon Usage Example
+
+```tsx
+import { Icons } from '@/components/ui/Icon';
+
+// Basic usage
+<Icons.Film />
+
+// With custom size
+<Icons.Search size={20} />
+
+// With styling
+<Icons.Calendar size={14} className="mr-1 text-blue-500" />
+```
+
+## Benefits
+
+1. **Consistent Visual Language**: All icons now match the Liquid Glass aesthetic
+2. **Better Scalability**: SVG icons scale perfectly at any size
+3. **Improved Accessibility**: Proper semantic icons instead of decorative emoji
+4. **Theme Support**: Icons adapt to light/dark mode through currentColor
+5. **Performance**: SVG icons load faster and render crisper than emoji
+6. **Maintainability**: Centralized icon system makes updates easier
+
+## Files Modified
+
+1. ✅ `components/ui/Icon.tsx` - Created
+2. ✅ `app/page.tsx` - Updated all icons
+3. ✅ `app/player/page.tsx` - Updated all icons
+4. ✅ `app/layout.tsx` - Added favicon config
+

+- Validates query and source parameters
+- Aggregates results from multiple sources
+- Returns merged results with source attribution
+
+**Request Format**:
+```json
+{
+  "query": "search term",
+  "sources": ["source_1", "source_2"],
+  "page": 1
+}
+```
+
+**Response Format**:
+```json
+{
+  "success": true,
+  "query": "search term",
+  "page": 1,
+  "sources": [

+
+## Data Flow
+
+### 1. Search Flow
+```
+User Input → Debounce (500ms) → API Route (/api/search)
+  → Parallel requests to sources → Normalize responses
+  → Merge & deduplicate → Display results
+```
+
+### 2. Video Selection Flow
+```
+User clicks video → Navigate to detail page → API Route (/api/detail)
+  → Fetch video details → Extract episodes → Parse M3U8 URLs
+  → Initialize player store → Navigate to player page
+```
+
+### 3. Playback Flow
+```
+Player page loads → Create HLS instance with AdFilteringLoader
+  → Load M3U8 URL → Filter ads → Initialize Artplayer
+  → Resume from saved position (if valid)
+  → Auto-save progress every 5s
+  → On video end: Clear progress, auto-play next if enabled
+```
+
+### 4. Source Switching Flow
+```
+User clicks "Switch Source" → Search video title across all sources
+  → Test each source speed (parallel):
+    - Fetch detail API
+    - HEAD request to first episode URL
+    - Calculate response time
+  → Sort by speed → Display with color indicators
+  → User selects source → Navigate to new URL with updated params
+```
+
+## Error Handling
+
+### HLS Errors
+- **Network Error**: Retry with `hls.startLoad()` (max 3 attempts)
+- **Media Error**: Call `hls.recoverMediaError()` (max 3 attempts)
+- **Buffer Stalled**: Restart loading
+- **Fatal Error**: Destroy player and suggest alternative source
+
+### API Errors
+- **Timeout**: Retry with exponential backoff
+- **404/500**: Mark source as unavailable
+- **Network Failure**: Show user-friendly message, suggest alternative
+
+### Recovery Strategies
+1. Auto-retry with exponential backoff (1s, 2s, 4s)
+2. Switch to alternative source if current fails
+3. Resume from last saved position after recovery
+4. Clear corrupted localStorage data and reset
+
+## Configuration
+
+### Adding Custom Sources
+```typescript
+import { addCustomSource } from '@/lib/api/video-sources';
+
+addCustomSource({
+  id: 'custom_source',
+  name: 'My Custom API',
+  baseUrl: 'https://api.example.com',
+  searchPath: '/api.php/provide/vod',
+  detailPath: '/api.php/provide/vod',
+  headers: { 'User-Agent': 'Mozilla/5.0' },
+  enabled: true,
+  priority: 3
+});
+```
+
+### Customizing Ad Filters
+```typescript
+import { addCustomAdPattern } from '@/lib/utils/m3u8-filter';
+
+addCustomAdPattern('/custom-ad-path/');
+```
+
+## Performance Optimizations
+
+1. **Parallel API Requests**: Fetch from all sources simultaneously
+2. **Request Timeout**: 15s timeout prevents hanging requests
+3. **Result Caching**: Speed test results cached for 5 minutes
+4. **Throttled Progress Saving**: Auto-save limited to every 5 seconds
+5. **Lazy Loading**: Episodes loaded only when needed
+6. **Ad Filtering**: Reduces bandwidth and loading time
+7. **Source Priority**: Faster sources prioritized automatically
+
+## Local Storage Keys
+
+- `kvideo_custom_sources`: Custom API sources
+- `kvideo-player-store`: Player settings (volume, rate, autoplay)
+- `kvideo-history-store`: Viewing history
+- `kvideo_progress_{source}_{videoId}`: Video progress
+- `kvideo_search_history`: Search query history
+- `kvideo_speed_test_cache`: Source speed test cache
+- `kvideo_episode_order`: Episode order preference
+- `kvideo_custom_ad_patterns`: Custom ad filter patterns
+
+## API Compatibility
+
+The platform expects third-party APIs to return JSON in this format:
+
+### Search Response
+```json
+{
+  "code": 1,
+  "list": [
+    {
+      "vod_id": 123,
+      "vod_name": "Video Title",
+      "vod_pic": "https://...",
+      "type_name": "Movie",
+      "vod_remarks": "HD",
+      "vod_year": "2024"
+    }
+  ]
+}
+```
+
+### Detail Response
+```json
+{
+  "code": 1,
+  "list": [
+    {
+      "vod_id": 123,
+      "vod_name": "Video Title",
+      "vod_pic": "https://...",
+      "vod_play_url": "Episode1$url1#Episode2$url2",
+      "vod_play_from": "m3u8"
+    }
+  ]
+}
+```
+
+## Next Steps
+
+1. **Install Dependencies**:
+```bash
+npm install zustand hls.js artplayer
+```
+
+2. **Configure API Sources**: Edit `lib/api/video-sources.ts` with real API endpoints
+
+3. **Build UI Components**: Create React components using the logic layers
+
+4. **Add Player Component**: Integrate HLS.js and Artplayer with the stores
+
+5. **Test Error Recovery**: Simulate network failures and verify recovery
+
+## Security Considerations
+
+- Never expose API keys in client-side code
+- Validate all user inputs before API requests
+- Sanitize video URLs before loading
+- Implement rate limiting on API routes
+- Use CORS properly for third-party API calls

+
+## Core Functionality
+
+### 1. Multi-Source Video Search
+
+```typescript
+// Example: Search across multiple sources
+import { searchVideos } from '@/lib/api/client';
+import { getEnabledSources } from '@/lib/api/video-sources';
+
+const sources = getEnabledSources();
+const results = await searchVideos('movie name', sources, 1);
+
+// Results include response time and source attribution
+results.forEach(result => {
+  console.log(`Source: ${result.source}`);
+  console.log(`Response time: ${result.responseTime}ms`);
+  console.log(`Results: ${result.results.length}`);
+});
+```
+
+### 2. Video Player State Management
+
+```typescript
+// Example: Using player store
+import { usePlayerStore } from '@/lib/store/player-store';
+
+function VideoPlayer() {
+  const { currentVideo, episodes, nextEpisode } = usePlayerStore();
+  
+  const handleVideoEnd = () => {
+    const next = nextEpisode();
+    if (next) {
+      console.log('Auto-playing next episode:', next.name);
+    }
+  };
+  
+  // Player component logic...
+}
+```
+
+### 3. Progress Tracking
+
+```typescript
+// Example: Save and restore progress
+import { saveProgress, getProgress, shouldResumeProgress } from '@/lib/utils/progress-tracker';
+
+// Save progress every 5 seconds
+const handleTimeUpdate = (currentTime: number) => {
+  saveProgress(videoId, source, currentTime, duration, episodeIndex);
+};
+
+// Resume on load
+const storedProgress = getProgress(videoId, source);
+if (shouldResumeProgress(storedProgress)) {
+  player.currentTime = storedProgress.position;
+}
+```
+
+### 4. Source Speed Testing
+
+```typescript
+// Example: Test and switch sources
+import { testAllSources, getSpeedIndicator } from '@/lib/utils/source-switcher';
+
+const results = await testAllSources(videoTitle, sources, currentSource);
+
+results.forEach(result => {
+  const indicator = getSpeedIndicator(result.speed);
+  console.log(`${result.sourceName}: ${indicator.label} (${result.speed}ms)`);
+});
+
+// Get fastest source
+const fastest = results.find(r => r.available);
+```
+
+### 5. M3U8 Ad Filtering
+
+```typescript
+// Example: Initialize HLS with ad filtering
+import Hls from 'hls.js';
+import { createAdFilteringConfig } from '@/lib/utils/m3u8-filter';
+
+const hls = new Hls(createAdFilteringConfig());
+hls.loadSource(m3u8Url);
+hls.attachMedia(videoElement);
+```
+
+## API Usage
+
+### Search Endpoint
+
+**POST** `/api/search`
+
+Request:
+```json
+{
+  "query": "movie name",
+  "sources": ["source_1", "source_2"],
+  "page": 1
+}
+```
+
+Response:
+```json
+{
+  "success": true,
+  "query": "movie name",
+  "page": 1,
+  "sources": [
+    {
+      "results": [...],
+      "source": "source_1",
+      "responseTime": 234
+    }
+  ],
+  "totalResults": 42
+}
+```
+
+### Detail Endpoint
+
+**GET** `/api/detail?id=123&source=source_1`
+
+Response:
+```json
+{
+  "success": true,
+  "data": {
+    "vod_id": 123,
+    "vod_name": "Movie Title",
+    "vod_pic": "https://...",
+    "episodes": [
+      {
+        "name": "Episode 1",
+        "url": "https://...",
+        "index": 0
+      }
+    ],
+    "source": "source_1"
+  }
+}
+```
+
+## Environment Variables
+
+Create `.env.local`:
+
+```bash
+# Optional: Default video sources
+NEXT_PUBLIC_DEFAULT_SOURCE_1=https://api.example1.com
+NEXT_PUBLIC_DEFAULT_SOURCE_2=https://api.example2.com
+
+# Optional: Analytics
+NEXT_PUBLIC_GA_ID=your-google-analytics-id
+
+# Development
+NODE_ENV=development
+```
+
+## Building for Production
+
+```bash
+# Build the application
+npm run build
+
+# Start production server
+npm start
+```
+
+## Testing
+
+### Test API Sources
+
+```bash
+# Use the health check function
+node -e "
+const { healthCheckSources, getAllSources } = require('./lib/api/video-sources');
+const sources = getAllSources();
+healthCheckSources(sources).then(results => {
+  results.forEach((result, sourceId) => {
+    console.log(sourceId, result);
+  });
+});
+"
+```
+
+### Test Search Functionality
+
+```bash
+# Test search via API route
+curl -X POST http://localhost:3000/api/search \
+  -H 'Content-Type: application/json' \
+  -d '{"query":"test","sources":["source_1"],"page":1}'
+```
+
+### Test Detail Fetch
+
+```bash
+# Test detail via API route
+curl "http://localhost:3000/api/detail?id=123&source=source_1"
+```
+
+## Common Issues
+
+### 1. HLS.js Not Loading
+
+**Solution**: Ensure the video URL is a valid M3U8 playlist and CORS is enabled on the video server.
+
+```typescript
+// Add CORS headers in next.config.ts if needed
+const nextConfig = {
+  async headers() {
+    return [
+      {
+        source: '/api/:path*',
+        headers: [
+          { key: 'Access-Control-Allow-Origin', value: '*' },
+        ],
+      },
+    ];
+  },
+};
+```
+
+### 2. LocalStorage Quota Exceeded
+
+**Solution**: The app auto-cleans old progress entries. You can also manually clear:
+
+```typescript
+import { clearOldProgress } from '@/lib/utils/progress-tracker';
+clearOldProgress(30); // Clear entries older than 30 days
+```
+
+### 3. Source Timeout
+
+**Solution**: Adjust timeout in `lib/api/client.ts`:
+
+```typescript
+const REQUEST_TIMEOUT = 15000; // Increase if needed
+```
+
+### 4. Ad Filtering Not Working
+
+**Solution**: Add custom patterns:
+
+```typescript
+import { addCustomAdPattern } from '@/lib/utils/m3u8-filter';
+addCustomAdPattern('/your-ad-path/');
+```
+
+## Browser Compatibility
+
+- ✅ Chrome 90+
+- ✅ Firefox 88+
+- ✅ Safari 14+
+- ✅ Edge 90+
+
+**Requirements**:
+- LocalStorage support
+- Fetch API
+- ES6+ JavaScript
+
+## Performance Tips
+
+1. **Limit Concurrent Sources**: Test with 3-5 sources max for optimal speed
+2. **Enable Caching**: Speed test results cached for 5 minutes
+3. **Throttle Progress**: Auto-save limited to every 5 seconds
+4. **Lazy Load Episodes**: Only fetch episodes when needed
+5. **Use CDN**: Serve static assets via CDN for faster loading

+
+## 🎬 Typical User Flow
+
+### Search & Play Flow
+1. User types search query → Debounced (500ms)
+2. POST to `/api/search` with selected sources
+3. Parallel requests to all sources with timeout
+4. Results normalized, merged, deduplicated
+5. User selects video → Navigate to detail
+6. GET `/api/detail?id=X&source=Y`
+7. Extract episodes and M3U8 URLs
+8. Initialize player with HLS + ad filtering
+9. Check for saved progress → Resume if valid
+10. Start playback → Auto-save progress every 5s
+11. On video end → Check autoplay → Load next episode
+
+### Source Switching Flow
+1. User clicks "Switch Source" button
+2. Search video title across all enabled sources
+3. Parallel speed tests:
+   - Fetch detail API
+   - HEAD request to first episode URL
+   - Calculate total response time
+4. Sort results: current first → by speed → errors last
+5. Display with color indicators (green/yellow/red)
+6. User selects faster source
+7. Navigate to new URL with updated params
+8. Keep same episode index if available
+
+## 📊 Performance Characteristics
+
+- **Search Speed**: Parallel requests complete in ~2-5 seconds
+- **Progress Save**: Throttled to every 5 seconds
+- **Source Test**: 10-second timeout per source
+- **Request Timeout**: 15 seconds with 3 retries
+- **History Limit**: 50 items max
+- **Cache Duration**: 5 minutes for speed tests
+
+## 🔧 Configuration Points
+
+### Video Sources (`lib/api/video-sources.ts`)
+```typescript
+export const DEFAULT_SOURCES: VideoSource[] = [
+  {
+    id: 'source_1',
+    name: 'Primary API',
+    baseUrl: 'https://api.example.com',
+    searchPath: '/api.php/provide/vod',
+    detailPath: '/api.php/provide/vod',
+    headers: { 'User-Agent': 'Mozilla/5.0' },
+    enabled: true,
+    priority: 1,
+  }
+];
+```
+
+### Timeouts & Limits (`lib/api/client.ts`)
+```typescript
+const REQUEST_TIMEOUT = 15000;  // 15 seconds
+const MAX_RETRIES = 3;          // 3 attempts
+const RETRY_DELAY = 1000;       // 1 second base
+```
+
+### Progress Settings (`lib/utils/progress-tracker.ts`)
+```typescript
+const PROGRESS_SAVE_THRESHOLD = 10;    // Skip if < 10s
+const RESUME_MIN_POSITION = 10;        // Resume if > 10s
+const RESUME_MAX_REMAINING = 120;      // Skip if < 2min left
+```
+
+## 🚀 Next Steps
+
+### Required:
+1. **Install Dependencies**: Run `npm install`
+2. **Configure Sources**: Update API endpoints in `video-sources.ts`
+3. **Build UI Components**: Create React components using the logic
+4. **Integrate Player**: Use HLS.js + Artplayer with the stores
+
+### Optional:
+5. Add authentication system
+6. Implement user favorites/bookmarks
+7. Add subtitle support
+8. Create admin panel for source management
+9. Add analytics and tracking
+10. Implement PWA features

+## 📝 Example Code Templates
+
+### SearchBar Integration
+```typescript
+import { debounce } from '@/lib/utils/search';
+import { useState } from 'react';
+
+const handleSearch = debounce(async (query: string) => {
+  const response = await fetch('/api/search', {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify({ query, sources: ['source_1'] }),
+  });
+  const data = await response.json();
+  setResults(data.sources.flatMap(s => s.results));
+}, 500);
+```
+
+### VideoPlayer Integration
+```typescript
+import Hls from 'hls.js';
+import { createAdFilteringConfig } from '@/lib/utils/m3u8-filter';
+import { usePlayerStore } from '@/lib/store/player-store';
+import { createProgressSaver } from '@/lib/utils/progress-tracker';
+
+const { currentVideo } = usePlayerStore();
+const saveProgress = createProgressSaver();
+
+useEffect(() => {
+  const hls = new Hls(createAdFilteringConfig());
+  hls.loadSource(currentVideo.url);
+  hls.attachMedia(videoRef.current);
+  
+  videoRef.current.addEventListener('timeupdate', () => {
+    saveProgress(
+      currentVideo.id,
+      currentVideo.source,
+      videoRef.current.currentTime,
+      videoRef.current.duration,
+      currentVideo.episodeIndex
+    );
+  });
+}, [currentVideo]);
+```
+
+### Source Switcher Integration
+```typescript
+import { testAllSources, getSpeedIndicator } from '@/lib/utils/source-switcher';
+import { getEnabledSources } from '@/lib/api/video-sources';
+
+const handleSwitchSource = async () => {
+  const sources = getEnabledSources();
+  const results = await testAllSources(videoTitle, sources, currentSource);
+  
+  results.forEach(result => {
+    const indicator = getSpeedIndicator(result.speed);
+    // Display with color: indicator.color
+  });
+};
+```
