The bandwidth assessment (BWE) is perhaps the most critical module in the WEBRTC video engine, which determines the amount of video data that can be generated when network congestion is not raised in video traffic.
Early bandwidth assessment algorithms are relatively primitive, mostly based on packet loss estimation, the basic strategy is to gradually increase the amount of data sent, until the loss of packets detected. In order for the sender to lear

For text chat rooms, as well as multiple screen interaction, we understand a lot more, I know there are two kinds of sockets and XMPP protocol. If we use Red5, a streaming media server based on Flash, in the development of live video, or voice chat rooms, we can use RTMP,RTSP. One, what is the main feature of the Red5 Red5 is similar to the Macromedia Company's FMS, a Java based Open-source streaming media server that provides streaming media ser
During this period of time, the work needs are converted from FLV stream to standard h264 and aac on rtmp. The server is an open-source project crtmpserver, client flex writing, video encoding h264, and audio encoding AAC, some protocol-related items are recorded as follows.
1. Analyze FLV data
Let's take a FLV file to analyze the FLV data format.

Video live streaming is the RTMP protocol for video real-time transmission, where the software we use is the Adobe Company'sOne is: Flash media Server4 Another is Flash media Live encoderBoth of these software:http://pan.baidu.com/share/link?shareid=256521uk=1711305891Installation and construction of Flash Media Server4 see:use Ckplayer and FMS to build rtmp video applicationsConnection: Http://www.ckplayer
The general steps to implement are:Step 1: Define Netconnection objects to connect rtmp and listen for netstatusevent.net_status eventsStep 2: Judge event.info.code== "NetConnection.Connect.Success" in the Netstatusevent.net_status event, through Sharedobject.getromote () Get Sharedobject ObjectStep 3: Listen for the Syncevent.sync event of the Sharedobject object and Sharedobj.connect (netconnection)Step 4: This time you can use Sharedobj.send () to
This time, the work of the need, on the rtmp to do the FLV stream to the standard H264, AAC conversion, the server is open source project Crtmpserver, client flex writing, Video coding H264, Audio coding AAC, now some of the agreements related to the following things record.
I. Analysis of FLV data
Let's take an FLV file to briefly analyze the format of the FLV data

If we want to encapsulate Speex encoding into rtmp or FLV, we may encounter problems with how to populate Audiotagheader, Speex encoding supports 8k,16k,32k sample rate, but only 16k in rtmp or FLV protocol, At this point the sampling rate needs to be treated as 11.025k, that is, the packet of this byte is 0xb6
For the AAC encoding in RTMP or FLV packets, AAC sa

Recently flv.js things seem to have ignition, and again to the MSE this thing to bring up.MSE (Media source extensions) is a new function of HTML5, and the general function is to realize streaming media function.If the MSE with WEBRTC and JS binary processing, then you can implement the server to send video to one of the browser users, the browser users will then transfer video streaming to other users of the function. is a web-side in the Peer-to-pee
The newer WEBRTC source has no voiceengine structure corresponding to the vidoeengine, replaced by Meidaengine. Mediaengine contains the Mediaengineinterface interface and its implementation compositemediaengine,compositemediaengine itself is also a template class, two template parameters are the audio engine and video engine respectively. Compositemediaengine derived classes Webrtcmediaengine dependent template parameters are Webrtcvoiceengine and We
ObjectiveThe purpose of this article is to save you 10 hours (or more) of your life, or to waste 10 minutes. WEBRTC's compilation has been called a nightmare as a large cross-platform base library that Google has frequently updated. If you happen to want to compile WEBRTC under Windows, you'd better evaluate your patience in advance.As of now, I have tried almost all the articles in the Chinese blog community, which can be said to have failed.

"WebRTC, a name derived from the abbreviation of Web real-time communication (Web real-time communication), is a technology that supports web browsers for real-time voice conversations or video conversations, and is Google's $68.2 million acquisition of global IP in 2010 Solutions company to get a technology, Google Open source of this technology! ”Just for the more than 60 million dollar technology, it is worth studying!
