注意 ：INFO: Using projection 1x1@1x1/0, 意味着 minicap 虽然运行了，但它只创建了一个 1x1 像素的虚拟屏幕, * Appium 或 MJPEG 接收到的图像无法作为有效画面显示
分析启动脚本run.sh
是使用 adb shell dumpsys window | grep -Eo 'init=[0-9]+x[0-9]+' | head -1 | cut -d= -f 2 获取的屏幕大小，单独执行这行命令，发现返回内容是1x1
解决方法 修复shell
adb shell dumpsys window | grep -Eo 'init=[0-9]{2,5}x[0-9]{2,5}' | head -1 | cut -d= -f 2 限制必须是2-5位的，过滤掉 个位数
