使用AHK控制Opera GX浏览器独立音量的技术需求

以下是适配Opera GX的AHK音量控制脚本，可在浏览器最小化时调节音量，基于Spotify版本修改而来：

If (!A_IsAdmin)
{
    MsgBox 请以管理员身份运行脚本！
    ExitApp
}

Process Exist, OperaGX.exe
ProcessId := ErrorLevel
If (!ProcessId)
{
    MsgBox Opera GX未运行！
    ExitApp
}

LCTRL & UP::SetAppVolume(ProcessId, GetAppVolume(ProcessId) + 5)
LCTRL & DOWN::SetAppVolume(ProcessId, GetAppVolume(ProcessId) - 5)
Return

GetAppVolume(PID)

修改说明 #

仅需对原Spotify脚本做两处核心修改：

• 将进程检测的Spotify.exe替换为Opera GX的进程名OperaGX.exe
• 将提示文本中的"Spotify"对应改为"Opera GX"，提升易用性

使用说明 #

• 脚本需以管理员身份运行，否则无法获取音频会话权限
• 快捷键：左Ctrl + 上箭头增加音量（每次+5%），左Ctrl + 下箭头降低音量（每次-5%）
• 若Opera GX未运行，脚本会弹出提示并退出
