Network Abstraction Layer Unit type (NALU):The Nalu header consists of a byte with the following syntax:+---------------+|0|1|2|3|4|5|6|7|+-+-+-+-+-+-+-+-+| F| nri| Type |+---------------+F:1 a bit.Forbidden_zero_bit. This one must be 0, as stipulated in the H.Nri:2 a bit.NAL_REF_IDC. Taking 00~11, it seems to indicate the importance of this nalu, such as 00 of the Nalu decoder can discard it without affecting the playback of the image.Type:5 a bit.Nal_unit_type. The type of this NALU unit is su

RTP (Real-time Transport Protocol) defines the standard packet format for sending videos and audios Based on the IP network. RTP and RTCP (RTP Control Protocol) work together. RTP carries media streams, while RTCP is used to monitor transmission statistics and Quality of Service (QoS) and assist in synchronization of m

RTP/RTCP/RTSP/SIP/SDP relationship1. RTPReal-time Transport Protocol is a Transport layer protocol for multimedia traffic on the Internet. The RTP protocol details the standard packet format for transmitting audio and video over the Internet. RTP protocols are commonly used in streaming media systems (with the RTCP protocol), video conferencing and a Push-to-talk

1. RTP speex Header The RTP Header is defined in [rfc3550. This document defines the usage of fields in the RTP Header. Payload type (PT): the charge type number in this format. Marker (m) bit: this bit is used to mark the beginning of a silent sound. Place it on the first package of the audio data. Speex supports sound detection and does not generate frame da

As a notebook less than 3000 yuan, cost-effective aspect is quite outstanding. Interface, Acer E1-471g-32342g50mnks has VGA, HDMI, 3 USB2.0 interface, and also equipped with two-in-one card reader, optical drive and other products, in

rapid development, this time I made a few stations, each station's independent IP is on the 3000-5000. Most of the 18W data included in Baidu. Which is today's data. Talk about my money experience, I now rent a server or a month to spend 600 yuan, but my server configuration is much better than before, I took out more than 10 g rental to my 6 friends, are engaged in business. On average, I got 1000 bucks per person, that is to sum up more than 6,000

The Code In this lab you will implement a streaming video server and client that communicate using the Real-Time Streaming Protocol (RTSP) and send data using the Real-Time Transfer Protocol (RTP ). your task is to implement the RTSP protocol in the client and implement the RTP packetization in the server. We will provide you code that implements the RTSP protocol in the server, the

This document describes a suitable for bundling, MPEG-2 encoding, RTP protocol can be applied to the video and audio frequency The payload type of the data. This is the second version. For this type of payload, when it is used in a VoD application system, Bundling has obvious advantages. This advantage is important enough to sacrifice the modularization of the separated audio video streams. This type of payload may be used. 1. Introduction This docume

H264 RTP Header Parsing ProcessCombined with naldecoder. c Analysis Protocol Analysis: Each RTP datagram consists of the header and payload. The meaning of the first 12 bytes of the header is fixed, the load can be audio or video data. The parameter set of the active sequence remains unchanged in the same encoding video sequence, and the parameter set of the active image remains unchanged in the same e

Http://bbs.chinavideo.org/viewthread.php? Tid = 7575 I believe many of you want to play h264 video streaming media like me. However, a newbie often does not know where to start. Using Baidu, Google, and other search materials is a treasure. After N weeks of thinking, I made some achievements. It took a lot of useless effort. I spent a week watching the English protocol, and later I learned that there was a Chinese version, in addition, the goal I have achieved is very simple, as long a

Above is the Internet multimedia architecture, we first have a overall impression. RTP (Real-time transport Protocol): RTP provides end-to-end transport for real-time applications, but does not provide any assurance of quality of service.
