How to Use FFVCL â Delphi FFmpeg VCL Components Video Encoder 7.4

FFVCL is a powerful and easy-to-use library that allows you to encode and decode video and audio files using the FFmpeg library in Delphi and C++Builder applications. With FFVCL, you can access the full features of FFmpeg without writing complex code or dealing with low-level APIs.

In this article, we will show you how to use FFVCL â Delphi FFmpeg VCL Components Video Encoder 7.4 to encode video files in various formats and codecs, such as MP4, AVI, MKV, H.264, HEVC, VP9, AAC, MP3, etc. We will also demonstrate how to use some advanced options and filters to customize the output quality and performance.

Step 1: Install FFVCL â Delphi FFmpeg VCL Components Video Encoder 7.4

To use FFVCL, you need to have Delphi or C++Builder installed on your computer. You also need to download and install the latest version of FFVCL from https://www.delphiffmpeg.com/. The installation package includes the FFVCL components, the FFmpeg binaries, the demo projects, and the documentation.

After installing FFVCL, you can find the components in the \"FFVCL\" tab of the component palette in the IDE. You can also open the demo projects in the \"Demos\" folder of the installation directory and explore how they work.

Step 2: Create a New Project and Add Components

To create a new project using FFVCL, you need to add at least two components: TFFEncoder and TFFPlayer. TFFEncoder is the main component that performs the encoding process. TFFPlayer is a simple video player that can display the input and output files.

To add these components, follow these steps:

Create a new VCL Forms Application project in Delphi or C++Builder.

Drop a TFFEncoder component on the main form.

Drop a TFFPlayer component on the main form.

Double-click on the TFFEncoder component to open its properties window.

Set the InputFile property to the path of the video file you want to encode.

Set the OutputFile property to the path of the output file you want to create.

Set the OutputFormat property to the format of the output file (e.g., mp4).

Set the OutputVideoCodec property to the codec of the output video stream (e.g., h264).

Set the OutputAudioCodec property to the codec of the output audio stream (e.g., aac).

Optionally, you can adjust other properties such as OutputVideoBitrate, OutputAudioBitrate, OutputFrameRate, OutputWidth, OutputHeight, etc. to change the output quality and size.

Step 3: Start Encoding and Play Files

To start encoding, you need to call the Encode method of the TFFEncoder component. You can do this in various ways, such as by clicking a button or using a timer. For example, you can add a TButton component on the main form and write this code in its OnClick event handler:

procedure TForm1.Button1Click(Sender: TObject);

begin

// Start encoding

FFEncoder1.Encode;

end;

To play the input and output files, you need to assign them to the FileName property of the TFFPlayer component and call its Play method. For example, you can add another TButton component on the main form and write this code in its OnClick event handler:

procedure TForm1.Button2Click(Sender: TObject);

begin

// Play input file

FFPlayer1.FileName := FFEncoder1.InputFile;

FFPlayer1.Play;

end;

You can also add another TButton component on the main form and write this code in its OnClick event handler:

procedure TForm1.Button3Click(Sender: TObject);

begin

// Play output file aa16f39245
