FFVCL– Delphi FFmpeg VCL Components V7.3a For Delphi 10.3 Rio
Video and audio processing is a common requirement for many applications, such as multimedia players, editors, converters, recorders, streamers, etc. However, implementing such functionality in Delphi can be challenging, as it involves dealing with complex formats, codecs, protocols, filters, and other aspects of multimedia data. Fortunately, there is a solution that can simplify this task: FFVCL Delphi FFmpeg VCL Components.
FFVCL– Delphi FFmpeg VCL Components v7.3a for Delphi 10.3 Rio
What is FFVCL?
Why use FFVCL?
FFVCL allows you to easily convert and play various multimedia files in Delphi applications, without the need for external codecs or command-line tools. You can use FFVCL components to encode and decode video and audio data from different sources, such as files, streams, cameras, microphones, etc. You can also use FFVCL components to apply filters and effects to video and audio streams, such as cropping, scaling, rotating, watermarking, etc. Moreover, you can use FFVCL components to stream video and audio data over network protocols, such as HTTP, RTSP, RTMP, etc.
FFVCL has many advantages over other solutions for video and audio processing in Delphi, such as:
It is native and fast. FFVCL components are written in Delphi and do not require any external dependencies or wrappers. They use the native FFmpeg libraries, which are optimized for speed and performance.
It is easy and flexible. FFVCL components have simple and intuitive properties, methods, and events that allow you to control the encoding, decoding, playback, and streaming of multimedia data. You can also customize the FFmpeg parameters and options for each component according to your needs.
It is powerful and comprehensive. FFVCL components support most multimedia formats, codecs, protocols, filters, and features that FFmpeg provides. You can use FFVCL components to handle almost any video and audio processing task in your Delphi projects.
In this article, I will provide you with a detailed guide on how to use FFVCL in your Delphi projects. I will also show you some examples of common tasks, such as encoding, decoding, streaming, and filtering video and audio files.
Installation and Setup
How to install FFVCL?
To install FFVCL on your system, you need to follow these steps:
Download the latest version of FFVCL from the official website. You can choose between the trial version or the full version. The trial version has some limitations, such as a watermark on the output video and a time limit on the playback. The full version requires a license key that you can purchase online.
Extract the downloaded ZIP file to a folder of your choice. You will find several subfolders inside the main folder, such as Binaries, Demos, Docs, Packages, Sources, etc.
Copy the FFmpeg DLLs from the Binaries folder to a folder that is accessible by your Delphi application. You can either copy them to the same folder as your executable file or to a system folder, such as C:\Windows\System32 or C:\Windows\SysWOW64.
Open Delphi 10.3 Rio and go to Component -> Install Packages. Click on Add and browse to the Packages folder of FFVCL. Select the appropriate package file for your Delphi version and platform. For example, if you are using Delphi 10.3 Rio 32-bit on Windows 10 64-bit, you should select FFVCL_D103.dpk. Click on Open and then OK.
You should see a new tab called FFVCL in the component palette of Delphi. It contains several components that you can use in your projects.
Congratulations! You have successfully installed FFVCL on your system.
How to configure FFVCL?
To configure FFVCL for your project, you need to follow these steps:
Create a new VCL application or open an existing one in Delphi.
Add the TFFGlobal component from the FFVCL tab to your main form. This component is responsible for loading and initializing the FFmpeg libraries. It also provides some global settings and events for all FFVCL components.
Select the TFFGlobal component and go to its Object Inspector. Set the DLLPath property to the folder where you copied the FFmpeg DLLs in step 3 of the installation process. For example, if you copied them to C:\Windows\System32, you should set DLLPath to 'C:\Windows\System32'.
Save and run your project. If everything is configured correctly, you should see a message box saying FFmpeg libraries loaded successfully. If you see an error message instead, check the log file or the OnLog event to find out what went wrong.
You have successfully configured FFVCL for your project. Now you can start using the other FFVCL components to perform various video and audio processing tasks.
How to use the TFFEncoder component?
The TFFEncoder component is used to encode video and audio data from different sources, such as files, streams, cameras, microphones, etc. You can use this component to convert multimedia files from one format to another, or to create new multimedia files from scratch.
To use the TFFEncoder component, you need to follow these steps:
Add the TFFEncoder component from the FFVCL tab to your form. This component has several properties, methods, and events that allow you to control the encoding process.
Select the TFFEncoder component and go to its Object Inspector. Set the Source property to the source of the video and audio data that you want to encode. You can choose from different source types, such as File, Stream, Device, Custom, etc. Depending on the source type, you may need to set other properties as well. For example, if you choose File as the source type, you need to set the FileName property to the path of the input file.
Set the Output property to the output of the encoded video and audio data. You can choose from different output types, such as File, Stream, Custom, etc. Depending on the output type, you may need to set other properties as well. For example, if you choose File as the output type, you need to set the OutputFileName property to the path of the output file.
Set the VideoCodec and AudioCodec properties to the codecs that you want to use for encoding the video and audio data. You can choose from a list of supported codecs by FFmpeg, such as H264, AAC, MP3, etc. You can also set other codec-related properties, such as VideoBitRate, AudioBitRate, VideoFrameRate, AudioSampleRate, etc.
You can also set other properties of the TFFEncoder component according to your preferences. For example, you can set the OnProgress event to handle the progress of the encoding process.
Call the Start method of the TFFEncoder component to start encoding. You can also call the Stop, Pause, and Resume methods to control the encoding process.
You can check the status of the encoding process by using properties such as State, ErrorMsg, TotalTime, etc.
You can also use methods such as CaptureFrame, CaptureImage, and CaptureAudio to capture frames, images, and audio samples from the input source during encoding.
When the encoding process is finished or stopped, you can access the output file or stream that contains the encoded video and audio data.
You have successfully used the TFFEncoder component to encode video and audio data from different sources. dcd2dc6462
