services. Some RTCP packets are issued between RTP sessions in a periodic manner to transmit functions such as listening service quality and exchanging session user information. The RTCP package contains statistics such as the number of sent data packets and the number of lost data packets. Therefore, the server can dynamically change the transmission rate or even the type of the payload. RTP and RTCP can be used together to optimize transmission efficiency with effective feedback and minimal o

Recently, due to a company's Android project, we need to upload a video to the server to enable upload, download, and play. This involves playing streaming media videos on the mobile terminal of the video. Therefore, I am working with a Darwin Streaming Media Server, this article also references: Baidu Library: Baidu?

The stream output function can output the streams read by the VLC to a file or send them over the network. The client can use HTTP, RTP, RTSP, and other protocols for access, transcoding, and other operations. Reference http://wiki.videolan.org/Documentation:Streaming_HowTo Stream output syntax % vlc input_stream --sout "#module1{option1=parameter1{parameter-option1},option2=parameter2}:module2{option1=...,option2=...}:..."

Let's analyze the rtpinterface. Void rtpinterface: setstreamsocket (INT socknum, unsigned char streamchannelid) There is no need to talk about setstreamsocket ().

Why does a host inside Nat have access to a Web server outside of NAT, but cannot get RTSP stream Media server stream? Reason: For protocols such as HTTP, the client establishes a socket connection with the Web server, which is monitored by a Web server that binds a fixed TCP port on this port. Clients located behind the NAT randomly select a TCP port connect (2) WEB SERVER. For RTSP streaming media servers

Real-time Streaming protocol RTSP (Realtimestreamingprotocol) is proposed by RealNetworks and Netscape, which defines how a one-to-many application can efficiently transfer multimedia data over an IP network. RTSP is located on the architecture of RTP (real-time transmission) and RTCP (real-time control), which uses TCP or RTP to complete the data transfer. HTTP transmits HTML compared to

1. Reflect function of DSS Darwin can receive and forward RTP data. This feature is described in the official document "reflect ".Using VLC, you can easily demonstrate this function by running the following command: vlc -vvv test.mp4 --sout "#dst=rtp{dst=127.0.0.1,port-audio=20000,port-video=20002,ttl=127,name=CHANNEL,sdp=file:///f:/channel.sdp}" Run the preceding command to generate an SDP description file channel. SDP. VLC will send the RTP packet to the specified port of the specified destina

the graphical interface or through command lines. Vlc1 requests media data from the Darwin server and then packs it into a TS stream and sends it out. vlc2 receives and plays TS stream data; Throughout the process, packet capture proves that the TS stream is in the middle. Of course, there is also a problem, that is, there will be mosaic in the image. It is assumed that there is a problem with the B frame PTS and DTs. Another problem is that the SDP file cannot be generated because we need to i
