What is the solution to the network video encoder failure?!

Currently, there are four main parts of the live webcast, video capture, video encoding, video transmission, and video distribution. The network video encoder is one of the video encoding devices, and is often used in network video conferences, video conferences, security surveillance and other places. Its main function is to encode the input video information into a data stream that can be transmitted by the network, thereby facilitating network transmission.

Usually support RTMP, HTTP and other network data transmission protocols, and in the network live broadcast often need to use RTMP push stream, then what is the RTMP push stream? The following small series introduces relevant content for everyone. As a kind of instrument, the network video encoder will inevitably have some shortcomings in the application process. What are the rare results? How to deal with it? Follow the experts of the Instrumentation World Network to master the disposal methods of these shortcomings.

Network video coding

The network video encoder PC can have a firewall, block the video preview port, and block the firewall to try to connect.

First, the communication network has achieved results

Second, the equipment operation has produced results and cannot operate normally.


Third, the remote encoder has a firewall at the front end of the Internet. Blocking the relevant video port may block the UDP video forwarding protocol.

 

Network video coding

In the live broadcast, it is often required to set an RTMP server address in the network video encoder to facilitate the RTMP push stream, that is, the encoded video information is pushed to the specified RTMP-enabled server, and then the viewer can access the address to abort. Watch the live stream in real time. The RTMP server push address is usually obtained from the webcast effectiveness platform, such as betta. This part requires you to register the relevant live platform account yourself, and then you can get the RTMP push stream address by observing the corresponding live broadcast effect. In fact, it is also a live broadcast space. It consists of rtmp://, including uploading the effective address, uploading the directory name (APP) and uploading node (stream).

The main role of the network video encoder is to stop the compression and de-tightening of the video signal. The computer industry defines true black through a 24-bit measurement system, which defines nearly a million colors, close to the limits of human vision. Today, the most basic VGA display has 640 x 480 pixels. This means that assuming a video demand is played at 30 frames per second, up to 27MB of information per second is transmitted, and a 1GB hard drive can only store about 37 seconds of video information. It is therefore necessary to stop the austerity of the information. The method of discarding some digital information or image information that is easily ignored by our eyes and brain reduces the amount of information in the video. The software or hardware that compresses and decompresses the video is the codec. The pinch rate of the codec varies from 2:1 to 100:1, making it possible to handle large amounts of video data.
