1、简介 目前，在IP网络中实现实时语音、视频通信和应用已经成为网络应用的一个主流技术和发展方向，本文详细介绍IP协议族中用于实时语音、视频数据传输的标准协议RTP（ Real-time Transport Protocol）和RTCP（RTP Control Ptotocol）的主要功能。 2、RTP/RTCP协议简介 RTP 由 IETF（ http://www.ietf.org/ ）定义在 RFC 3550和3551中。 RTP被定义为传输音频、视频、模拟数据等实时数据的传输协议，与传统的注重的高可靠的数据传输的运输层协议相比，它更加侧重的数据传输的实时性，此协议提供的服务包括数据顺序号、时间标记、传输控制等。 RTP通常与辅助控制协议RTCP一起工作，RTP只负责实时数据的传输，RTCP负责对RTP的通信和会话进行带外管理（如流量控制、拥塞控制、会话源管理等）。 3、RTP/RTCP协议层次和封装 RTP位于传输层（通常是UDP）之上，应用程序之下，实时语音、视频数据经过模数转换和压缩编码处理后，先送给RTP封装成为RTP数据单元，RTP数据单元被封装为UDP数据报，然后再向下递交给IP封装为IP数据包。 RTP分组只包含RTP数据，而控制是由另一个配套协议RTCP提供。RTP在端口号1025到65535之间选择一个未使用的偶数UDP端口号

I have a DLL one of my applications uses to receive video from RTSP cameras. Under the hood, the DLL uses FFMPEG libs from this release zip : ffmpeg-20141022-git-6dc99fd-win64-shared.7z We have a wide variety of cameras in house and most of them work just fine. However, on one particular Pelco Model Number: IXE20DN-OCP, I am unable to connect. I tested the camera and rtsp connection string on VLC and it connects to the camera just fine. I found the connection string here : http://www.ispyconnect.com/man.aspx?n=Pelco rtsp://IPADDRESS:554/1/stream1 Oddly, even if I leave the port off of VLC, it

背景分析 RTMP是Real Time Messaging Protocol（实时消息传输协议）的首字母缩写，该协议基于TCP，是一个协议族，包括RTMP基本协议及RTMP/RTMPS/RTMPE等多种变种。RTMP是一种设计用来进行实时数据通信的网络下ieyi，主要用来在Flash/AIR平台和支持RTMP协议的流媒体/交互服务器之间进行音视频和数据通信。 RTMP推流，就是将直播内容推送到服务器的过程。 关于RTMP推流组件 EasyRTMP是一套调用简单、功能完善、运行高效稳定的RTMP推流功能组件，经过多年客户实战和线上运行打造，支持RTMP推送断线重连、环形缓冲、智能丢帧、网络事件回调，支持Windows、Linux、ARM、Android、iOS平台，支持市面上绝大部分的RTMP流媒体服务器，能够完美应用于各种行业的直播需求，手机直播、桌面直播、摄像机直播、课堂直播等方面。结合EasyDSS流媒体服务器，为开发者提供专业、稳定的直播推流、转码、分发服务，全面满足低超低延迟、超高画质、超大并发访问量的要求。 EasyRTMP-Android 视频采集 解决问题 EasyRTMP-Android推流，使用手机相机来采集视频数据： 1、声明相机权限和相机特征权限 <uses-feature android:name="android.hardware.camera" />

I'm trying to stream live video from my android phone to a desktop RTSP server on my PC. The streamed video can be played in another device. I'm using H.264 video encoder, so the SDP returned by the server (as the reply of DESCRIBE request) should contain the profile-level-id and sprop-parameter-sets fields. The Spydroid project shows how to extract these info from a dummy file recorded to SD card by parsing it (from the avcC block). But I cannot do it like that. In Spydroid, the media recorder and the RTSP server are on the same device, so the server can always record a test file with the

I have a simple Rtsp Client...The client send Rtsp Commands to Rtsp Server and get RTP packets from server. The problem is that after a time( about 3-4 minute) my 3rd party RTSP Server drop connection with my RTSP Client. I have not implemented RTCP...I take rtp packets from rtsp server but does not send any RTCP PACKET... I make simple search and find that some guys use some RTSP commands[ like OPTIONS, SET PARAMETER-GET PARAMETER ] too keep alive Connections between RTSP Server and Client... But in my case that does not work... Here is my questions: What is the best way to keep alive
