This article original from the http://blog.csdn.net/voipmaker reprint indicate the source. Dual-stream is the concept in video conferencing. It generally means that the client can display two video streams at the same time, one is the main video (main), and the other is usually the content sharing (slides ), it is also called share content. Content is usually screen, PPT, document, and other content. The SIP protocol implements dual-stream. The SDP contains two video media tags. One is main, wh

1. BackgroundWith the popularization of broadband Internet and great technological advances, VoIP has become a technology that can rival traditional telephone services and PBX products. The VoIP Terminal samples and codes audio and video analog signals into Compressed Frames, and then converts them into IP packets for transmission, thus achieving multimedia communication on the IP network. This article analyzes several factors that may affect the collection/playback performance based on the requ

After reading the introduction of H264/AVC codec, I just left the following three articles in my mind:1, H264 does not understand how to implement a codec, just a coded video bit stream syntax, and the Bitstream decoding method, this is similar to MPEG.2, H264 and once the standard (such as H261, H263, MPEG-1, MPEG-4) codec implementation process is not much different, the basic difference is the details of each function block.3, H264 is to use the co

) SDP Syntax: SDP is also described in text format. An SDP description can contain many rows. The format of each row is as follows:Type = ValueType is represented by only one letter. An SDP description usually consists of a session-level and multiple media-level information. Session-level information is used to describe the entire session, each media-level information is used to describe a specific media stream. Session-level starts with "V = 0" and media-level starts with "M = V = 0O = Bob 2890

interaction Graph If you want to encapsulate your own source and render filters, you must first select your own codec. For video codec, choose h261, h263, or mepg4. for audio, choose g729 or g711, be sure first. With codec selected, encapsulation is easy.Let's talk about it more. Let's take a look at the code I have provided. First, define the CLSID of the four RTP filters used. Static const guid clsid_fg729render = {0x3556f7d8, 0x5b5, 0x4015,

Currently, the following types of common audio and video encoding are available: MPEG series: (developed by the mpeg [Motion Image Expert Group] affiliated to ISO [International Standards Organization) Video Encoding mainly involves mpeg1 (which is used for VCD), MPEG2 (used for DVD), and MPEG4 (currently DVDRip uses its variants, suc
