One 、 Preface

Video upload is used to upload locally stored video files to the cloud server , Indirectly realize the function of storing local video to the cloud , In fact, it is stored locally first , After the file is generated, upload it to the cloud , The final effect is the same , To expand compatibility , A separate video upload module is directly made , You can select the video file to upload on the interface and check , You can query by date and time , Channel query, etc , You can customize the address and port of the cloud server , Click one click upload to see the upload progress of each video file . They all use multi-threaded uploading , You can upload multiple files at the same time , Each file has a file size and upload progress display . At present, they are all uploaded manually , Automatic uploading mechanism can be added in the later stage , Listen for folder changes （ Once a change occurs, find the corresponding newly added video file ） Or file storage completion signal , Trigger upload immediately .

Video upload features

Multithreading to send and receive files , Support encrypted transmission .
The receiver supports two ways: listening port receiving files and active connection server receiving files .
according to File start + file size + The contents of the document + End of file Receive one by one by subcontracting .
It can decrypt and output the received encrypted file package .
If the file is received by connecting to the server, the request file can be specified .
The form of the request file of the receiver can be used as a general program upgrade scheme .
The progress bar updates the progress of sending and receiving files in real time .
The sender can set the maximum size of each packet, that is, the number of slices and packets .
The sender can encrypt each packet of the file .
The sender supports merging and sending packets .
You can specify a directory to search the request file sent by the client .
Each function is an independent class , The interface is clear and friendly , Easy to use .
Support any Qt edition 、 Any system 、 Any compiler .
