One, foreword

Video upload to upload local store video files to the cloud server, indirectly, realized the function of local video memory to the cloud, it is essentially a stored locally first, files are generated and then uploaded to the cloud, the ultimate effect is same, in order to expand the compatibility, made a separate video upload module directly, You can select the video file to be uploaded on the interface. You can query by date, time, channel, etc. You can customize the address and port of the cloud server. Click one-click upload to view the upload progress of each video file. Multithreading is used to upload, you can upload multiple files at the same time, each file has file size and upload progress display. At present, all upload is manual, and automatic upload mechanism can be added later to monitor the change of folder (once the change occurs, the corresponding newly added video file can be found) or the signal of file storage is finished, and the upload will be triggered immediately.

Video uploading features

  • Multithreaded send and receive files, support encryption transmission.
  • The receiving end supports two modes: listening port to receive files and actively connecting to the server to receive files.
  • Subcontract and receive according to start of file + file size + file content + end of file.
  • Can decrypt the received encrypted file package output.
  • The request file can be specified if the file is received by connecting to the server.
  • The form of the receiver request file can be used as a general program upgrade scheme.
  • 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 slice subcontracting.
  • The sender can encrypt each packet of the file.
  • The sender supports packet merging and sending.
  • You can specify a directory to search for request files sent by clients.
  • Each function independent of a class, the interface is clear and friendly, easy to use.
  • Support any Qt version, any system, any compiler.
