used to obtain its unique identity, and the Getaudiotracks () and Getvideotracks () methods can be used to obtain an array of the stream's tracking objects (if a stream is not opened, its tracking object array will be an empty array) Constraint object (Constraints)
The constraint object can be set in the Addstream method of Getusermedia () and Rtcpeerconnection, which is the WEBRTC used to specify what stream to accept, which can define the followin
After using Getusermedia to get the stream, you need to output it, typically binding to the output on the Video tab, and you need to use window. Url.createobjecturl (Localmediastream) to create a blob URL that can be played in video using the SRC attribute, notice that the AutoPlay attribute is added to the video, or only one picture can be captured Once the stream has been created, the Label property can be used to obtain its unique identity, and the Getaudiotracks () and Getvideotracks () met

Constraintshas been implemented by Chrome, FireFox, and Opera. These can be used to set the video resolution obtained by Getusermedia () and Rtcpeerconnection Addstream (). The goal is to implement other constraint

By exchanging the SDP, both parties will be able to know some basic information about what the other is transmitting.
A and B establish links that need to get each other's candidate separately.How to get video and audio streamingThe above process only provides how to make a and B links, then how to transfer the video stream?
The browser provides

A, b each creates a PC instance configured with an ice server and adds a Onicecandidate event callback to it
When a network candidate is available, the Onicecandidate function is called
Inside the callback function, a or B encapsulates the network candidate's message in an ice candidate signaling, which is routed through the server to the other party
When a or B receives an ice candidate signaling sent by the other party via the ser
