Pixel 7 使用minicap: A Comprehensive Guide

The Google Pixel 7 is a powerful and feature-rich smartphone, known for its advanced camera system, smooth performance, and user-friendly interface. If you’re a developer or an advanced user looking to interact with your Pixel 7 in more sophisticated ways, you might be interested in using Minicap—a versatile tool for screen capturing and interaction. In this article, we’ll walk you through what Minicap is, how to set it up on your Pixel 7, and its practical applications.

What is Minicap?

Minicap is a lightweight tool used for capturing screenshots and recording screen activity on Android devices. It provides a high-resolution, real-time display of the device’s screen, which can be particularly useful for developers testing apps, creating tutorials, or even for users who want to record gameplay or other activities.

Minicap works by accessing the device’s display buffer and transmitting the image data to a computer or another device where it can be viewed, recorded, or analyzed. Unlike other screen capture tools, Minicap operates with minimal overhead, ensuring smooth performance and high-quality captures.

Setting Up Minicap on Your Pixel 7

Before you start using Minicap, you need to set up your Pixel 7 for development and install the necessary tools. Here’s a step-by-step guide:

1. Prepare Your Pixel 7

• Enable Developer Options: Go to Settings > About phone, and tap Build number seven times to enable Developer Options. You’ll see a message confirming that Developer Options are now enabled.
• Enable USB Debugging: Go to Settings > System > Developer options, and toggle USB debugging on. This allows your Pixel 7 to communicate with your computer.

2. Install ADB (Android Debug Bridge)

• Download ADB: You can download ADB as part of the Android SDK Platform Tools from the official Android Developer website.
• Install ADB: Extract the downloaded ZIP file and navigate to the extracted folder. You can use ADB from the command line by navigating to this folder.

3. Download and Set Up Minicap

• Download Minicap: You can find Minicap binaries for various devices, including the Pixel 7, on repositories like GitHub or other Android developer forums. Ensure you download the version compatible with your device.
• Install Minicap: Transfer the Minicap binary to your Pixel 7 using ADB. Open a command prompt or terminal and use the following command:
  bash

  Copy code

  adb push minicap /data/local/tmp/minicap
adb shell chmod 755 /data/local/tmp/minicap

• Install Minicap Library: Similarly, push the Minicap library to your device:
  bash

  Copy code

  adb push minicap.so /data/local/tmp/minicap.so
adb shell chmod 755 /data/local/tmp/minicap.so


4. Start Minicap

• Launch Minicap: You need to start Minicap using a command that sets up the necessary display parameters. Use the following command in your terminal:
  bash

  Copy code

  adb shell LD_LIBRARY_PATH=/data/local/tmp /data/local/tmp/minicap -P 1080x2400@1080x2400/0


  Adjust the resolution and orientation (1080x2400@1080x2400/0) according to your device’s screen specs.

• View the Output: To view the captured screen, you can use tools like VLC or ffplay to stream the output. For example:
  bash

  Copy code

  adb forward tcp:1717 localabstract:minicap
ffplay tcp://localhost:1717
