Conclusion
FFVCLâ Delphi FFmpeg VCL Components v7.3a is a powerful and easy-to-use solution for video encoding and decoding in Delphi applications. It supports the latest FFmpeg libraries and provides a rich set of events and methods for controlling the encoding and decoding process. If you are looking for a native VCL component that can handle audio and video files with high performance and flexibility, you should give FFVCLâ Delphi FFmpeg VCL Components v7.3a a try.How does FFVCLâ Delphi FFmpeg VCL Components v7.3a work?
FFVCLâ Delphi FFmpeg VCL Components v7.3a works by wrapping the FFmpeg libraries in a native VCL component that can be easily integrated into Delphi applications. The FFmpeg libraries are dynamic link libraries (DLLs) that provide low-level access to audio and video codecs, filters, formats and protocols. The FFmpeg libraries are updated frequently to support the latest standards and technologies in the multimedia field.
The TFFVideoEncoder component allows you to encode audio and video files from various sources, such as files, streams, cameras, microphones, etc. You can specify the output format, codec, bitrate, resolution, frame rate, quality and other parameters for the encoding process. You can also apply filters and effects to the input or output streams, such as cropping, scaling, rotating, watermarking, etc. The TFFVideoEncoder component supports multiple threads and can encode multiple files or streams simultaneously.
The TFFVideoPlayer component allows you to play audio and video files from various sources, such as files, streams, URLs, etc. You can control the playback speed, volume, position and other aspects of the playback process. You can also capture frames or audio samples from the playing stream and save them to files or memory. The TFFVideoPlayer component supports multiple windows and can play multiple files or streams simultaneously.
