The video that Fig. 5 shows one embodiment of the invention offer draws stream method, and the method is applied to view networked server,
The following steps are included:
Step 501, the monitoring acquisition request for a monitoring device that view networked terminals are sent is received.
Wherein, access service system is monitored depending on networked server；Acquisition request is monitored come networked terminals of considering oneself as；Depending on networking
Terminal with depending on can be based on communicating depending on networking protocol between networked server.The monitoring in some place is watched depending on networked terminals,
The monitoring acquisition request for being directed to a monitoring device (i.e. target monitoring equipment) is sent to view networked server, so that view the Internet services
Device draws stream for the video of the monitoring device, pulls the video code flow of the monitoring device according to monitoring acquisition request, starting.
Specifically, code stream (Data Rate) refers to the data traffic that video file uses within the unit time, is Streaming Media
The unit of transfer of technology；Stream media technology is a kind of technology for transmitting the multi-medium datas such as audio, video by stream socket,
User can be to play, without complete downloading data file in downloading.
Optionally, monitoring device can be camera or have other electronic equipments of camera function.
It can be the terminal devices such as server, interchanger or client depending on networked terminals.
As the first example, as shown in fig. 6, view networked server passes through view networking between two view networked terminals respectively
Connection receives the monitoring acquisition request of view networked terminals A, view networked terminals B, third-party platform belonging to Xiang Suoshu monitoring device
Pull video code flow.
Step 502, third-party platform belonging to Xiang Suoshu monitoring device pulls video code flow, and it is flat to monitor the third party
The response time of platform.
Wherein, after receiving monitoring acquisition request depending on networked server, the monitoring device that monitoring acquisition request is directed to is determined, and
Determine third-party platform belonging to the monitoring device；Third-party platform is the video code flow for receiving and depositing monitoring device acquisition
Server can communicate between multiple monitoring devices.
Video code flow is pulled to third-party platform depending on networked server, that is, pulls the video resource of third-party platform；It is optional
Connection is established depending on networking communication protocol depending on may be based between networked server and third-party platform in ground, supervises depending on networked server
Survey the response time of the third-party platform.
If third-party platform sends data to view networked server, third-party platform is received and parsed through depending on networked server
The data of transmission therefrom find related code stream information；According to the different encapsulation format demultiplexing of code stream, respectively obtain encoded
Video data and audio data；Audio, video data is decompressed using hard decoder or soft decoding；Original view is obtained after decoding
Frequency evidence is with audio data and synchronous by the two, is finally sent to view networked terminals.
Step 503, if the response time is more than default response time threshold value and the non-pushing video of the third-party platform
Code stream pulls video code flow to the third-party platform again.
Wherein, the non-pushing video code stream of third-party platform includes two kinds of situations: not receiving third party depending on networked server
The data that platform is sent, and it is not resolved to video code flow from the data that third-party platform is sent.If the response time is super
Default response time threshold value and the non-pushing video code stream of third-party platform are crossed, then may be that intermediate signaling loss or third party are flat
The program of platform handles exception, pulls video code flow to the third-party platform again depending on networked server at this time, pulls third party
The video resource of platform.
In this way, view networked server can be put down to third party after the case where third-party platform non-pushing video code stream occurs
After platform sends primary monitoring resource acquisition request, in each default response time threshold value, executes once pull video codes respectively
Stream operation, until third-party platform pushing video code stream, avoids obtaining depending on networked server to third-party platform transmission monitoring resource
After taking request, it is constantly in the state for waiting third-party platform response, leads to that video code flow can not be received depending on networked terminals,
Appearance monitors the case where without stream；If continuous several times pull, and third-party platform does not push, then may have abnormal conditions.
In the above embodiment of the present invention, the monitoring acquisition request for a monitoring device that view networked terminals are sent is received；
Video code flow is pulled to third-party platform belonging to the monitoring device, and monitors the response time of the third-party platform；If
The response time is more than default response time threshold value and the non-pushing video code stream of the third-party platform, then in each default sound
It answers in time threshold, executes once pull video code flow operation respectively, until third-party platform pushing video code stream or identification are different
It often happens, in this way, can repeatedly be held after sending primary monitoring resource acquisition request to third-party platform depending on networked server
Row draws stream operation, avoids the occurrence of the case where monitoring is without stream, improves the success rate for transferring monitoring, promote the usage experience of user；This
Inventive embodiments solve in the prior art, if the intermediate signaling loss or the between view networked server and third-party platform
The program of tripartite's platform handles exception, causes to monitor the problem of networked terminals can not watch monitoring.
Optionally, in the above embodiment of the present invention, the prison for a monitoring device for receiving view networked terminals and sending
The step of controlling acquisition request, comprising:
Receive the monitoring acquisition request that the view networked terminals are sent by view networking transparent protocol；
The monitoring acquisition request is parsed, the monitoring device that the monitoring acquisition request is directed to is obtained.
