Ffvcl - Delphi Ffmpeg Vcl Components 5.0.1 Fixed Jun 2026

You can input and output frames in various formats, including RGB, MJPEG, H.263, H.264, and YUV.

He opened the component palette. There they sat, looking deceptively simple among his standard edit boxes and panels: TFFDecoder , TFFEncoder , TFFPlayer .

: Developers can directly inject raw data (such as custom Delphi TBitmap graphic canvas instances or device context handles) directly into the stream, allowing on-the-fly programmatic video generation.

Previous versions sometimes caused deadlocks when seeking or stopping decoding. The 5.0.1 rewrite uses a safer producer-consumer queue with thread-pool support, making it suitable for long-running server-side or background processing. FFVCL - Delphi FFmpeg VCL Components 5.0.1

Encoder.AudioBitrate .

GDI-based screen and wave capture (perfect for building screen recorders). 4. Video Filtering & Previews

is a significant historical release in a suite of native VCL components designed to wrap the FFmpeg libraries for Delphi developers. Version 5.0.1, released around late 2012, marked a transition to more modern FFmpeg cores and expanded hardware/interface integration. Core Purpose and Value You can input and output frames in various

Set your desired video/audio codec, bitrate, and resolution.

FFVCL allows you to: Capture progress via events (OnProgress, OnLog). Access raw frame data in memory for custom processing.

: Execute complex FFmpeg operations entirely in-memory using clean, structured Delphi code. : Developers can directly inject raw data (such

uses FFVCL.Components; procedure GetVideoDuration(const FileName: string); var Decoder: TFFDecoder; begin Decoder := TFFDecoder.Create(nil); try Decoder.FileName := FileName; Decoder.Open; // Output the resolution and duration ShowMessage(Format('Resolution: %dx%d | Duration: %s', [Decoder.VideoWidth, Decoder.VideoHeight, FormatDateTime('hh:nn:ss', Decoder.Duration)])); Decoder.Close; finally Decoder.Free; end; end; Use code with caution.
