HoweverPhonon backend plugin cocould not be loaded. This is the absence of backend plug-ins. At this time, the program cannot do anything except display the interface.

For VLC to build a streaming media server, please refer to my previous article based on mobile platform multimedia framework-using VLC to build a simple streaming media server. Here need to pay attention to a few configuration places, one is to choose destination time to choose RTP instead of RTSP, and then
start with a simple UDP receiver to see what information we can accept from the RTP server. To achieve this, you need to have a certain degree of network programming experience, as to the specific operating system, programming environment, development language, etc. are not limited. For simplicity, I'm using Python to give you a small example of the program.[Python]View Plaincopy

How to implement real-time monitoring of haikang cameras in HTML?
Recently, the company has arranged for CCFA to implement real-time monitoring of a webpage playback camera. Baidu has been on the Internet for a long time, and many of them are directly implemented using the vlc plug-in. However, currently mainstream browsers do not support the vlc plug-in, and it has not been successful for a long time.

Structural Patterns Structural model1. Adapter mode (Adaptor)Purpose: Converts a class/interface to another form that the client expects. Adapters allow classes to work together, otherwise they will not work because of incompatible interfaces. By adding an interface to encapsulate an existing subclass, the client is programming to the interface, thus hiding the specific subclass.Suppose we have a MediaPlayer interface and an entity class Audioplayerthat implements the MediaPlayer interface.

H.264 supports motion vectors of 264 or 1/4 pixels. When the accuracy is 1/4 pixels, a 6-stroke filter can be used to reduce high-frequency noise. For motion vectors with a precision of 1/8 pixels, a more complex 8-stroke filter can be used. During Motion Prediction, the encoder can also select an "enhanced" interpolation filte
