我正在尝试捕获相机直播流并从中制作HLS流。我使用的是Fantech Luminous C30网络摄像头。我得到这个错误:

似乎FFmpeg在试图从您的网络摄像头捕获视频时报告了一个错误。错误信息"Fantech Luminous C30: No such file or directory"中给出的网络摄像头的路径或名称可能有问题。出现此错误的一个可能原因是FFmpeg无法找到网络摄像头。确保网络摄像头已连接到您的计算机，并安装了网络摄像头的驱动程序。确保FFmpeg使用正确的网络摄像头。也可能是FFmpeg没有从网络摄像头捕获视频所需的编解码器或库。确保正确配置和编译了FFmpeg，并且提供了所有必需的库。您是否尝试使用其他应用程序打开您的网络摄像头?
