3.Step 3: Run Scrcpy on Windows/macOS:Launch the Scrcpy executable to initiate low-latency mirroring.

Download the latest Scrcpy release on your computer. Extract the zip file and run scrcpy.exe (or use terminal command scrcpy on macOS). Your smartphone display will instantly mirror in an uncompressed window on your PC monitor.

Method B: Hardware Capture Card Pipeline for iOS & Android (Professional Setup)

Using a dedicated HDMI/USB-C capture card ensures maximum stability, zero latency, and perfect audio capture without consuming smartphone CPU cycles.

1.Step 1: Connect Smartphone to HDMI Output Adapter:Output a clean HDMI video feed from your smartphone.

• iPhone 15/16 & Modern Android: Connect a USB-C to HDMI Adapter (or USB-C Hub with HDMI pass-through) to your phone.
• Lightning iPhones: Connect an official Apple Lightning to Digital AV Adapter.

2.Step 2: Route HDMI into Your Capture Card:Route the video signal into your computer broadcast capture card.

Plug an HDMI cable from your phone’s adapter into the HDMI IN port of your capture card (e.g., Elgato HD60 X). Connect the capture card’s USB 3.0 output cable directly to a high-speed USB port on your PC.

3.Step 3: Add Capture Device Source in OBS Studio:Configure video feed inside OBS Studio for recording.

Open OBS Studio, navigate to the Sources box, click +, and select Video Capture Device. Choose your capture card from the drop-down menu and set Resolution to 1920×1080 at 60 FPS.

3. Configuring OBS Studio for Mobile Game Recording

Once your phone screen appears on your computer monitor, set up OBS Studio to capture crisp 60 FPS video and clean desktop audio:

1. Add Your Display or Window Source:
   • If using Scrcpy or a desktop software window, add a Window Capture source in OBS and select the mirroring window.
   • If using a physical capture card, use a Video Capture Device source.
2. Separate In-Game Audio & Voice Chat:
   • Add an Audio Output Capture source in OBS to record internal game sounds directly from your PC system audio or capture card.
   • Add an Audio Input Capture source to assign your USB desktop microphone separately, allowing you to edit microphone commentary and game audio independently on separate audio tracks.
3. Optimize Video Output Encoding:
   • Go to Settings > Output > Recording. Set Format to MP4 or MKV.
   • Select your hardware encoder: NVIDIA NVENC (H.264/AV1) or AMD HW H.264/AV1.
   • Set Rate Control to CBR (Constant Bitrate) with a bitrate of 12,000 Kbps to 20,000 Kbps for crystal-clear 1080p 60FPS recordings destined for YouTube or social media editing.

4. Tips to Eliminate Lag, Thermal Throttling, and Audio Noise

High-resolution mobile gaming can strain smartphone thermals. Keep your mobile capture pipeline running smoothly with these optimizations:

1. Use a Powered USB Hub / Charging Passthrough: Playing and streaming simultaneously drains phone batteries fast. Use a USB-C multi-port hub supporting Power Delivery (PD) so your phone charges while outputting video data.
2. Lower Smartphone Thermal Stress: Remove thick phone cases, lower device screen brightness (since you are viewing the game on your PC monitor anyway), and avoid playing under direct sunlight.
3. Fix Audio Desynchronization: If wireless audio lags behind your video feed, navigate to OBS Audio Mixer > Advanced Audio Properties and add a minor positive or negative Sync Offset (e.g., +100ms) to align your audio tracks perfectly.
