帮助：UDP 广播 vlc 流怪异！

发布于 2024-10-14 06:57:28 字数 331 浏览 12 评论 0原文

您好，我正在尝试使用 vlc 在 LAN 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}

问题是它可以在某些网络上运行，并且我在没有路由器的网络上接收它时遇到问题！

问：“239.255.xx”地址有什么神奇之处？除了交换机和电缆之外，UDP 广播还需要哪些网络硬件？无线可以接受UDP广播吗？

感谢您的回答！

Hi I'm trying using vlc to broadcast UDP stream within a LAN, Making it like a TV channel.

I used command line to launch VLC which then vlc is ok to run =

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

problem is it works on some network, and I have problem receiving it on a network without router!

Question: what is some magical about the address "239.255.x.x" ? what network hardware is require for UDP broadcast besides switches and cables? Does wireless can accept UDP broadcast?

Thanks for your answers!

239.255.xx 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（其中有一些特定用途的区域）。

您已经正确地注意到，没有路由器它就无法工作。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。您可以添加多播静态路由（该地址或所有多播地址），也可以设置默认网关。

在此处阅读有关使用命令行选项的信息。

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.
