Easydss anonymous live channel data volume instability optimization scheme sharing

EasyDSS As a streaming media transmission platform supporting video on demand , You can upload video files by yourself , You can also play the uploaded on-demand file as a virtual live broadcast . meanwhile , In terms of video file upload , We also added new features , That is, regularly upload the latest video files to the file server .

In the test EasyDSS During anonymous live broadcast in, the data of the number of online anonymous live broadcast channels is often unstable , For example, always online 20 Data , Sometimes it shows 10 strip , Sometimes it shows 20 strip .

Look at the code , The data information of each anonymous live broadcast update is as follows ： Receive the live stream information from the kernel , First, check whether the live broadcast or virtual live broadcast is available in the database , If you don't find , It is considered as anonymous live broadcast .

When the front end queries , Part of the data is due to the speed of database update , Not updated in time , So the problem arises .

The original code is as follows ：

//  Update stream information 
gLives.Set(group.StreamName, sessionInfo)
gSessChan <- sessionInfo

gSessChan <- sessionInfo This line of code is to send data to the channel , In addition, judge according to the database .

So we modified the code as follows ：

if !gLives.Has(group.StreamName) {
   //  Push into the channel , Process information according to the database 
   //  If this is the first time online , Update type 
   gSessChan <- sessionInfo
} else {
   info, _ := gLives.Get(group.StreamName)
   oldSessionInfo := info.(*dto.SessionInfo)
   sessionInfo.Name = oldSessionInfo.Name
   sessionInfo.Type = oldSessionInfo.Type
}
//  Update stream information 
gLives.Set(group.StreamName, sessionInfo)

If the corresponding type is found in the historical data , Use the original data type directly . After modification, the data is stable and normal .

EasyDSS The use of the scene is very rich , The updated version is also more and more in line with the update of modern technology and the use needs of users , In addition to the online education we mentioned above 、 In addition to the application of video on demand , It can also be extended to the Internet of things 、 Logistics warehousing 、 Mobile monitoring and other aspects , One of the most popular ones is the realization of UAV EasyDSS Video streaming live broadcast , We have also made many plans for live video broadcasting of UAVs , Welcome to know and test .
