• Excellent quality
• Very efficient
• SeaMeet supports automatically

AMD GPUs:

Radeon HD 7000 series and newer:
• VCE (Video Coding Engine)
• Good quality
• Efficient encoding
• Automatic support

Intel Integrated:

4th gen Core and newer:
• Quick Sync Video
• Surprisingly good quality
• Very power efficient
• Great for laptops

3. Gaming Features

   (works alongside SeaMeet)

Part 4: macOS-Specific Features and Setup

macOS Advantages

1. Polished Interface

SeaMeet on Mac feels native:

• Follows macOS design guidelines
• Uses native controls
• Respects system theme
• Touch Bar support (on compatible Macs)
• Proper menu bar integration

2. Excellent Apple Silicon Support

M1/M2/M3 chips work great:

Apple Silicon Features:
• Hardware acceleration via VideoToolbox
• Excellent performance per watt
• Fast encoding
• Cool operation
• Long battery life while recording

3. System Integration

macOS Integration:
• iCloud Drive support
• Time Machine compatible
• Handoff/Continuity ready
• Proper sandboxing
• Security-scoped bookmarks

macOS Limitations

1. System Audio Requires Permission

Unlike Windows, macOS needs explicit permission:

Setup Steps:

1. First time recording system audio:
   System Preferences → Security & Privacy → Privacy
   
2. Click "Screen Recording" on left

3. Check "SeaMeet" in the list
   (You may need to unlock with your password)

4. Restart SeaMeet completely

5. System audio will now work

Why This Is Required:

macOS security model
Screen recording captures everything
User must explicitly allow
Protects against spyware

2. No NVIDIA/AMD Hardware Acceleration

Mac Hardware Acceleration:
• Intel Macs: Intel Quick Sync (if available)
• Apple Silicon: VideoToolbox (excellent)
• External GPUs: Not supported for encoding
• No NVENC or AMD VCE (chips not present)

Performance:

Apple Silicon is so efficient it doesn't matter
Intel Macs with Quick Sync are fine
Older Intel Macs without Quick Sync use CPU encoding

3. Sandboxing Restrictions

macOS Security:
• Apps are sandboxed
• Must request permission for:
  - Microphone
  - Camera (if used)
  - Screen recording
  - File system locations
  - Downloads folder
  - Desktop

SeaMeet will prompt for these as needed

macOS Setup Guide

First-Time Setup:

1. Install SeaMeet

2. Grant permissions (Critical!):
   System Preferences → Security & Privacy → Privacy
   
   Enable for:
   ☑ Screen Recording
   ☑ Microphone
   ☑ Accessibility (for some shortcuts)
   
3. Restart SeaMeet

4. Test recording

5. For system audio:
   - SeaMeet uses BlackHole (virtual audio driver)
   - Or may use built-in loopback on newer macOS
   - Follow in-app instructions

macOS-Specific Shortcuts

Global Shortcuts:
• Cmd + Shift + R — Start/Stop recording
• Cmd + Shift + F — Save Flashback
• Cmd + Shift + S — Screenshot

macOS Integration:
• Touch Bar: Record button (if available)
• Menu Bar: Quick controls
• Notification Center: Recording status

Part 5: Linux-Specific Information

Linux Characteristics

1. Variable Experience

Linux versions vary by distribution:

Ubuntu (Recommended):
• Best supported
• Easiest setup
• Most features work
• Regular testing

Fedora:
• Good support
• Newer packages
• May need extra repos

Other distros:
• Your mileage may vary
• Community support
• May need manual fixes

2. Audio Capture Complexity

Linux audio is more complex:

Audio Systems:
• PulseAudio (most common)
• PipeWire (newer, modern)
• ALSA (low-level)
• JACK (professional audio)

Setup Required:
May need to create virtual audio devices
Or use loopback modules
Not "plug and play" like Windows

PulseAudio Setup:

# Create virtual sink for system audio
pactl load-module module-null-sink sink_name=SeaMeet sink_properties=device.description=SeaMeetRecording

# Monitor it
pactl load-module module-loopback source=SeaMeet.monitor

3. Hardware Acceleration Varies

NVIDIA on Linux:
• NVENC available via proprietary drivers
• Must install separately
• Quality good when working

AMD on Linux:
• VCE support varies by driver
• Open-source vs proprietary drivers
• May need configuration

Intel on Linux:
• VA-API for encoding
• Usually works well
• Part of Mesa drivers

Linux Setup Guide

Ubuntu Installation:

# Download .deb package
# Or install via repository if available

sudo dpkg -i seameet-linux.deb
sudo apt-get install -f  # Fix dependencies

# Grant permissions
