+### Screen Casting Issues
+
+#### FFmpeg Not Found
+
+**Symptoms**: Screen casting fails to start, FFmpeg errors
+**Solutions**:
+1. Install FFmpeg on your system:
+   ```bash
+   # Linux
+   sudo apt-get install ffmpeg
+   # macOS
+   brew install ffmpeg
+   # Windows
+   # Download from https://ffmpeg.org/download.html
+   ```
+2. Verify FFmpeg is in PATH: `ffmpeg -version`
+3. Check FFmpeg permissions and accessibility
+
+#### Chromecast Discovery Fails
+
+**Symptoms**: No devices found, network discovery errors
+**Solutions**:
+1. Verify devices are on same network subnet
+2. Check router multicast/broadcast settings
+3. Ensure Chromecast devices are powered on
+4. Restart network equipment and Chromecast devices
+5. Check firewall rules for multicast traffic
+
+#### Screen Capture Permission Issues
+
+**Symptoms**: Screen capture fails, permission errors
+**Solutions**:
+
+**macOS**:
+1. Open System Preferences → Security & Privacy → Privacy
+2. Enable Screen Recording permission for Python/Terminal
+3. Restart application after granting permissions
+
+**Windows**:
+1. Run application as Administrator if needed
+2. Check Windows Privacy settings for screen capture
+3. Ensure antivirus is not blocking screen capture
+
+**Linux**:
+1. Verify X11 display access: `echo $DISPLAY`
+2. Check X11 permissions: `xhost +local:`
+3. Ensure user is in audio group for audio capture
+
+#### Audio Capture Issues
+
+**Symptoms**: Video works but no audio in stream
+**Solutions**:
+1. Check audio device availability:
+   ```bash
+   # Linux
+   pactl list sources short
+   # Windows
+   # Check Windows Sound settings
+   # macOS
+   # Check System Preferences → Sound → Input
+   ```
+2. Verify microphone permissions
+3. Test audio with system tools before streaming
+4. Check for audio device conflicts with other applications
+
+#### Network Streaming Problems
+
+**Symptoms**: Chromecast can't access stream, connection errors
+**Solutions**:
+1. Verify local IP detection is correct
+2. Check firewall rules for HTTP streaming port (default 8000)
+3. Test stream URL manually: `http://your-ip:8000/stream.mp4`
+4. Ensure network bandwidth is sufficient for chosen bitrate
+5. Try different streaming port if current is blocked
