Frequently Asked Questions
为什么摄像头显示黑屏？▼
通常是另一个应用（如Zoom或Teams）正在独占使用摄像头。关闭其他视频应用重试。还要检查摄像头是否被隐私盖遮挡，以及浏览器设置中是否已授予摄像头权限。
可以测试外接摄像头和麦克风吗？▼
可以。如果连接了多个设备，使用下拉菜单选择要测试的摄像头或麦克风。外接USB摄像头和麦克风在操作系统识别后会出现在列表中。连接新设备后可能需要刷新页面。
此工具会录制或保存视频或音频吗？▼
不会。此工具仅显示测试用的实时预览。不会录制、保存或发送任何视频或音频数据。摄像头和麦克风流仅存在于浏览器内存中，点击停止按钮或离开页面后完全停止。
