AArch64平台下Cuttlefish WebRTC无法显示设备屏幕求助

该问题已在互联网上被多位用户反馈，我也遇到了相同问题——在AArch64机器上启动Cuttlefish后，访问本地WebRTC地址无法连接到安卓虚拟设备屏幕。

重现步骤 #

• 在AWS创建a1.metal实例或其他支持裸机/嵌套虚拟化的AArch64机器
• 安装Ubuntu 22.04 ARM64系统
• 配置ubuntu-desktop及VNC服务器以远程查看屏幕
• 在AArch64机器上安装Firefox
• 按照官方指南配置Cuttlefish
• 启动Cuttlefish后访问https://localhost:8443，无法建立与安卓虚拟设备屏幕的连接

日志信息 #

启动时屏幕输出：

~/work/avd$ HOME=$PWD ./bin/launch_cvd --daemon --start_webrtc=true

已尝试的解决方案 #

• 通过strace确认Cuttlefish在avd/bin目录查找libEGL.so，下载对应AArch64版本的库文件放入该目录
• 从源码编译基于Mesa llvmpipe的软件渲染器并安装到主机系统

以上方法均未解决libEGL.so加载失败问题，请求提供其他解决方案建议。
