4369: epmd, a peer discovery service used by RabbitMQ nodes and CLI tools
5672, 5671: used by AMQP 0-9-1 and 1.0 clients without and with TLS
25672: used for inter-node and CLI tools communication (Erlang distribution server port) and is allocated from a dynamic range (limited to a single port by default, computed as AMQP port + 20000). Unless external connections on these ports are really necessary (e.g. the cluster uses federation or CLI tools are used on machines outside the subnet), these ports should not be publicly exposed. See networking guide for details.
35672-35682: used by CLI tools (Erlang distribution client ports) for communication with nodes and is allocated from a dynamic range (computed as server distribution port + 10000 through server distribution port + 10010). See networking guide for details.
15672: HTTP API clients, management UI and rabbitmqadmin (only if the management plugin is enabled)
61613, 61614: STOMP clients without and with TLS (only if the STOMP plugin is enabled)
1883, 8883: (MQTT clients without and with TLS, if the MQTT plugin is enabled
15674: STOMP-over-WebSockets clients (only if the Web STOMP plugin is enabled)
15675: MQTT-over-WebSockets clients (only if the Web MQTT plugin is enabled)
在视频传输领域,MP4虽然常见,但在直播场景中直接使用MP4格式存在诸多问题。例如,MP4文件的头部信息(如ftyp、moov)较大,导致初始加载时间较长,影响用户体验。相比之下,HLS(HTTP Live Streaming)协议及其M3U8格式更具优势。HLS通过将视频切分成多个小片段,并生成一个M3U8播放列表文件,实现低延迟和高稳定性。本文详细介绍了如何将TS文件转换为M3U8直播流,包括技术原理和具体操作步骤,帮助读者更好地理解和应用这一技术。 ...
