Lightweight RTSP service RTSP Streaming module and module application scenarios difference

Many developers have been confused lightweight SDK and RTSP service RTSP push the difference between the SDK (flow Github Download ), the following are the relevant differences:

1. Lightweight RTSP service modules : Core lightweight RTSP service trigger point is resolved to avoid the user or the developer alone or RTMP RTSP service deployment , for local audio and video data (e.g., camera, microphone), encoded, built converged RTSP service, provide external flows for RTSP URL to pull, lightweight RTSP service, applies to the next within the network environment , to concurrent less demanding scenes, supports H.264 / H.265, support RTSP authentication, unicast multicast mode, taking into account the carrying capacity of a single service, we support RTSP create multiple services, and support services to obtain the number of the current RTSP session connection.

The following is the interface to explain (to Android platform as an example):

Android SDK built lightweight RTSP service interfaces Detailed
Call description	interface	Interface Description
General Features	Android RTMP end push all functions remain active, while also pushing RTMP
SmartRTSPServerSDK
Initialization RTSP Server	InitRtspServer	Init rtsp server (and UnInitRtspServer paired even start multiple RTSP service, but also just called once InitRtspServer, make sure to call before OpenRtspServer)
Create a rtsp server	OpenRtspServer	Create a rtsp server, returns a handle rtsp server
Set Port	SetRtspServerPort	Set rtsp server listening port, the port must be set before StartRtspServer
Set authentication user name and password	SetRtspServerUserNamePassword	Set rtsp server authentication username and password, this can not be set, only to be re-authentication settings
Gets the current number of sessions rtsp server	GetRtspServerClientSessionNumbers	Gets the current client sessions rtsp server, this interface must be re-called after StartRtspServer
Start rtsp server	StartRtspServer	Start rtsp server
Stop rtsp server	StopRtspServer	Stop rtsp server
Close rtsp server	CloseRtspServer	Close rtsp server
UnInit rtsp server	UnInitRtspServer	UnInit rtsp server (and InitRtspServer paired even start multiple RTSP service, but also just called once UnInitRtspServer)
SmartRTSPServerSDK call for Publisher Interface
Set the rtsp stream name	SetRtspStreamName	Set the rtsp stream name
To be published rtsp stream rtsp server settings	AddRtspStreamServer	To be published rtsp streaming settings rtsp server, a stream can be published to multiple rtsp server, create a startup rtsp server, please refer to OpenRtspServer and StartRtspServer Interface
Clear rtsp server settings	ClearRtspStreamServer	Clear rtsp server settings
Start rtsp stream	StartRtspStream	Start rtsp stream
Stop rtsp stream	StopRtspStream	Stop rtsp stream

2. Push RTSP streaming module: RTSP module plug flow, plug flow, and RTMP similar module, suitable for the environment within the network or public network , mainly for third-party service docking RTSP , such darwin stream server, RTSP or third party service platform, such as server-specific scenarios such as video analysis platform that supports H.264 / H.265, supports TCP, UDP transmission mode is set, and also supports authentication service, the main advantage is that the RTSP protocol UDP piece, but UDP packet, public easy to block live network, and that network instability easy loss, so the scene can push RTMP streams generally recommended to go RTMP, need special docking system, walk RTSP.

The following is the interface to explain (to Android platform as an example):

Call description	interface	Interface Description
Setting a push transmission RTSP	SetPushRtspTransportProtocol	transport_protocol: 1 rtp for UDP transport packet; 2 represents TCP packet transmission rtp
Set push the RTSP URL	SetPushRtspURL	Set push the RTSP URL
Push start RTSP	StartPushRtsp	Initiate a push RTSP streaming
Stop pushing RTSP	StopPushRtsp	Stop pushing RTSP streaming
