Summary:
The SDP protocol is also known as the Session Description Protocol. In the live app source code platform, real-time communication services are provided for users by defining real-time communication parameters and managing session information and media data to ensure the quality and stability of communication. For example: in the live app source code In the live broadcast room of the platform, the SDP protocol can communicate with the anchor in real time for the audience to realize the real-time communication between the anchor and the audience.
introduction:
In this modern era when most people surf the Internet, the live app source code platform needs to meet the market demand and build a high-quality live app source code platform to ensure the smooth transmission and playback of audio and video data. The SDP protocol has many The role is to ensure the high quality of the source code of the live app. Next, I will introduce the function of the SDP protocol of the source code of the live app.
- Description of session information: The SDP protocol of the live app source code first describes the session information, including; session attributes, session address, session format, etc., and specifies the length of the session ID to identify different sessions. The SDP protocol describes the session information to help the live app source code platform understand the session, so as to adapt and process it.
- Media stream negotiation and support: In the live app source code platform, there are different media streams, and different media streams require correct transmission to achieve correct information interaction. The SDP protocol supports different media streams, allowing the device and server of the live app source code to Negotiate the attribute parameters of the media stream, so that different media streams can be transmitted correctly, ensure the correct processing of media data, and ensure that the live app source code platform can correctly realize information interaction.
- It is used in combination with multiple protocols; there are many high-quality protocols in the live app source code platform (I have already talked about five in the past, and I will talk about more later, of course, this is all later), these protocols are respectively They have different functions. In special cases, if the SDP protocol cannot fully meet the needs, the SDP protocol can be used in combination with these protocols to meet different network environments and needs, so that the live app source platform can provide better services.
- Provide encryption and authentication information: The SDP protocol can provide encryption and authentication information to protect the security of data transmission in the live app source code platform.
The SDP protocol builds the reference code in the source code part of the live app:
class SDP:
def __init__(self):
self.version = 0
self.origin = ""
self.session_name = ""
self.media = ""
def to_str(self):
sdp_str = "v={}\r\n".format(self.version)
sdp_str += "o={}\r\n".format(self.origin)
sdp_str += "s={}\r\n".format(self.session_name)
sdp_str += "m={}\r\n".format(self.media)
return sdp_str
sdp = SDP()
sdp.version = 0
sdp.origin = ".com" # 设置源信息(示例)
sdp.session_name = "bogokj-bugukj" # 设置会话名称（示例）
sdp.media = "video bogokj" # 设置媒体信息（示例）
sdp_str = sdp.to_str()
print(sdp_str)in conclusion:
Through my analysis, it can be seen that the SDP protocol plays an important role in the live app source code platform, describing session information, media stream negotiation support, combination of multiple protocols, and encryption authentication, all of which enable the live app source code platform to achieve high quality Stable data transmission and processing provide users with better protection and experience, and enhance the competitiveness of the live app source code platform in the market.
