Let's look at this function: maid Code: select all gintgst_rtp_buffer_compare_seqnum (guint16 seqnum1, guint16 seqnum2){  return (gint16) (seqnum2 - seqnum1);} A simple code can be used to determine whether seqnum1 and seqnum2 have

Based on the practices in the past few days, we have found an Optimal Configuration: 1. The SIP server uses trixbox. If you are familiar with Linux, we recommend that you use asterisk directly. 2 If the client is used directly, it is recommended

The recent progress is a bit slow, the PWM (Raspberry Pi has 2 pwm legs, but I need 4, check the N multiple scheme or DMA drive Gpio analog PWM method) and interrupt (because know the hardware so I do not want to poll the way the encoder come over

Real-time transfer implementation based on the jrtplib library in Linux I. RTP is a standard protocol and Key Technology for Real-Time Streaming Media transmission. Real-Time Transport Protocol (PRT) is a network protocol used to process multimedia data streams over the Internet. It can be used in one-to-one (unicast, unicast) scenarios) or you can transmit streaming media data in real time in a one-to-multiple (Multi-play) network environment.

Use DirectShow to implement QQ's audio/video chat function Currently, popular instant messaging tools, such as MSN and QQ, all implement the video and audio functions. Through video and audio, we can better communicate with our friends through the network, this article uses DirectShow technology to simulate QQ to achieve video and audio acquisition, transmission, and basically implement the QQ video and audio chat function. The main function of the network video/audio system is the collection of

) protocol is a connection-oriented transport protocol, the communication needs to establish a connection, transmission delay is large, TCP recognition and retransmission mechanism, flow control mechanism can ensure reliable data transmission, but the processing process is complex and inefficient, for audio and video streaming , frequent acknowledgement and retransmission cannot guarantee the real-time transmission of data, so it is relatively unsuitable for the transmission of video images.

Section 5. transmitting and receiving media JMF and real-time transmission protocol (RTP) Many friendly network features are directly built in JMF, which makes it easy for client programs to transmit and receive media over the network. When a user on a network wants to receive media streams of any type, it does not need to wait for all broadcasts to be downloaded to the machine before watching the media; users can watch broadcasts in real time. This c

Transport Protocol III, RTSP (real Time streaming Protocol) The above streaming media playback based on progressive downloading can only support on-demand and cannot support live broadcast, the rate at which the media stream data arrives at the client is not precisely controlled, and the client still needs to maintain a buffer storage space of the same size as the media file on the server, waiting for a long buffer time before it can begin playback, resulting in poor real-time performance, Duri
