Delphi Video Development: A Comprehensive Guide for Beginners36

Introduction

Delphi is a powerful and versatile programming language that can be used to create a wide variety of applications, including video editing and playback programs. In this tutorial, we'll walk you through the basics of video development with Delphi, including how to load, play, and edit video files.

Loading Video Files

To load a video file into a Delphi application, you can use the LoadFromFile method of the TMediaPlayer component. This method takes the path to the video file as an argument and loads the file into the player.
procedure (const FileName: string);
begin
(FileName);
end;

Playing Video Files

Once a video file has been loaded, you can start playing it by calling the Play method of the TMediaPlayer component. This method starts the playback of the video.
procedure ;
begin
;
end;

Stopping Video Files

To stop the playback of a video file, you can call the Stop method of the TMediaPlayer component. This method stops the playback and returns the player to its starting position.
procedure ;
begin
;
end;

Pausing Video Files

To pause the playback of a video file, you can call the Pause method of the TMediaPlayer component. This method pauses the playback and allows you to resume playback later by calling the Play method.
procedure ;
begin
;
end;

Seeking in Video Files

To seek to a specific position in a video file, you can use the Seek method of the TMediaPlayer component. This method takes the desired position in milliseconds as an argument and seeks to that position in the video.
procedure (const Position: integer);
begin
(Position);
end;

Editing Video Files

Delphi also provides a number of components and methods that can be used to edit video files. For example, the TVideoEditor component can be used to trim, split, and merge video files. The TVideoEffects component can be used to add effects to video files, such as fades, transitions, and filters.
procedure (const StartPosition: integer; const EndPosition: integer);
begin
(StartPosition, EndPosition);
end;

Conclusion

In this tutorial, we've covered the basics of video development with Delphi. We've shown you how to load, play, stop, pause, and seek in video files. We've also shown you how to edit video files using the TVideoEditor and TVideoEffects components. With this knowledge, you can start creating your own video applications in Delphi.
