Question

您好我正在尝试使用vlc在局域网内广播UDP流，使其像电视频道一样。

我使用命令行启动VLC，然后vlc可以运行=

cvlc --repeat filename.avi --sout '#standard{access=udp,mux=ts,dst=239.255.12.42:8001}

问题是它适用于某些网络，我在没有路由器的网络上接收它有问题！

问题：地址“239.255.x.x”有什么神奇之处？除交换机和电缆外，UDP广播需要什么样的网络硬件？无线可以接受UDP广播吗？

感谢您的回答！

Answer 1

239.255.x.x地址是多播地址空间的一部分，范围从224.0.0.0到239.255.255.255（并且有一些特定用途区域）。

您已正确注意到没有路由器它无法正常工作。这是因为基本IP堆栈仍然想知道如何路由这些地址以确定将它们发送到哪个接口。您可以为多播添加静态路由（该地址或所有多播地址），也可以放入默认网关。

更具体的答案：

standard (alias std)

Sends a stream.

Options:

access: how to send: file, udp, rtp, http.

mux: which muxer (ie, which format) will be used. It can be one of avi (for AVI format) ogg (for OGG format) ps (for MPEG2-PS format) ts (for MPEG2-TS format).

url: if you use the file access, it will be the location where to store the stream; if you use another access, it will be the unicast or multicast IP address where you want to stream.

sap: if you use the udp or rtp accesses, use this option to announce your stream, using SAP/SDP.

name! This option contains the name under which you want to announce the program.

slp: like sap, but use the SLP protocol. You need to have libslp on your system.

sap_ipv: if you use the sap option, use this option to specify if you want to send the SAP announces in IPv4 or IPv6. The value of this option is 4 or 6.
