FFVCL – Delphi FFmpeg VCL Components Video Encoder 7.4


FFVCL is a native VCL components suit including Video Encoder and Video Player VCL components which wrap FFmpeg libraries perfectly. FFVCL is more easy, more flexible and more powerful than the official FFmpeg command line interface for converting and playing audio and video files.

What’s FFmpeg?
FFmpeg is a complete solution to record, convert and stream audio and video. It includes libavcodec, the leading audio/video codec library. FFmpeg is developed under Linux, but it can compiled under most operating systems, including Windows.

Relation between FFVCL and FFmpeg
Because FFVCL is a direct wrapper of FFmpeg’s libavcodec APIs, it is able to reflect the power of FFmpeg libraries. And it is more flexible and more powerful than the official FFmpeg command line interface. At the same time, FFVCL is very easy to use. Therefore, FFVCL is better than FFmpeg CLI in some measure.

Architecture
Add-ons are used for input and/or output of FFEncoder, FFPlayer, FFDecoder.
FFEncoder provides audio/video formats transcoding: intput -> decoding(decompression) -> encoding(compression) -> output.
FFPlayer plays audio and video files.
FFDecoder provides media file information and decoding video frames or audio samples.
FFLogger catchs the log generated by (Add-ons, FFEncoder, FFPlayer, FFDecoder and FFmpeg libraries).
FFLoader provides loading DLLs in run-time dynamic linking.
DLLs includes FFmpeg libraries, SDL library, SoundTouch library, and libmfx library.
Add-ons
MemoryAccessAdapter provides memory access for intput and output (open, read/write, seek, close).
FrameInputAdapter provides directly video frames input (Bitmap canvas, Bitmap data, Bitmap DeviceContext, YUV).
FrameOutputAdapter provides directly video frames output (RGB, MJPEG, H.263, H.264, YUV).
PacketInputAdapter provides directly video packets input (H.263, H.264, MJPEG, M4V, MPEGVideo, VC1).
WaveInputAdapter provides directly PCM wave data input.
WaveOutputAdapter provides directly PCM wave data output.
GDICapture provides screen capturing for video input and wave recording for audio input.
DShowCapture(built in ffmpeg libraries) provides webcam capturing for video input and wave recording for audio input.
Please refer the demos for more information.
FFEncoder
FFEncoder is powerful and a little complex, please refer to the encoder document and demos.
DLLs needed: AVCodec, AVDevice, AVFilter, AVFormat, AVUtil, SwResample, SwScale and libmfx(optional).
FFPlayer
FFPlayer is easy to use and still not powerful enough, please refer to the demo application.
DLLs needed: AVCodec, AVDevice, AVFilter, AVFormat, AVUtil, SwResample, SwScale, SDL and SoundTouch(optional).
FFDecoder
FFDecoder is easy to use, please refer to the demo application.
DLLs needed: AVCodec, AVFilter, AVFormat, AVUtil, SwResample, SwScale.
FFLogger
FFLogger is an assistant component, it will be automatically created as a global instance when necessary, and only one instance is allowed.
FFLoader
FFLoader is an assistant class, it will be automatically created as a global instance at startup. Please forget it.
FFmpeg Libraries
FFmpeg libraries with GPL/LGPL: AVCodec, AVDevice, AVFilter, AVFormat, AVUtil, SwResample, SwScale.
AVCodec provides decoders and encoders of audio/video stream.
AVDevice provides VFW capturing and DirectShow capturing.
AVFilter provides video filter for special effects.
AVFormat provides demuxers and muxers of containers.
AVUtil provides common utilities.
SwResample provides audio resampling.
SwScale provides video frames resampling.
SDL Library
SDL provides audio playback and video rendering.
SoundTouch Library
SoundTouch provides resampling audio for changing tempo(speed).
libmfx Library
libmfx provides Intel QSV dispatcher.
