BIGSPEED Video Compression SDK is a low-complexity, high-performance engine for quick development of video streaming applications.
It incorporates video capture and video compression/decompresion in a single COM automation object.
The component uses DirectX9 to enumerate the installed capture devices and available capture formats.
The used capture format is 24bit RGB bitmaps. The frame rate can be set in the range from 1 to 30 fps.
The compression ratio is adjustable and can vary from 50:1 to 500:1. At frame rate set to 15 fps and format selected to 160x120 pixels
the output bitrate is 6-8 Kbps.
BIGSPEED Video Compression SDK utilizes an elegant event-driven paradigm for easy integration into Windows applications.
A special attention is paid to provide responsive user interface while maintaining low CPU usage.
Carefully designed set of properties, methods, and events offers great flexibility to develop innovative communication software.
Sample applications are included in Visual Basic 2005, and Delphi 7.
The API is described using the syntax of VB.NET programming language.
System Requirements: Windows 9X/NT or later
System Requirements: N/A

Ratio - useful command line utility for compression ratio computation more>>
As input it receives the list of files and produces a column of compression ratios.
The first file in a list is the reference file, others are test files.
Output numbers are compression ratios between reference file and each test file.
Reference file and at least one test file should be specified.
Options:
--help (-h) Display this information
--version (-v) Display program version
--reference (-R) Reference file
--test (-T) Test file
--show-reference (-r) Use reference file as test file
--show-name (-n) Display file name
--show-size (-s) Display file size
--kb (-k)
--mb (-m)
--gb (-g) Display file size in KB, MB, GB
--percent (-p) Display percent instead of ratio
--precision Precision value

However, the compression ratio is thus far lower than that for .mp3 files - you can expect around 50%, worse for heavier music and better for classical etc
Features:
- Windows frontend (which also supports many other codecs).
- Best compression currently available (see comparison).
- Versions for both Windows and Linux OSes.
- Winamp, foobar2000 and Xmms plugins for playback
Direccional codec 1.0
(Lossless Windows codec that compress motion) with good compression ratio more>> Another motion codec (Lossless Windows codec that compress motion) with good compression ratio.
This codec uses the "direccional" algorithm. The word "Direccion" means address in spanish. This method tries to compress the colour information of an image using the address of the colours. This address is a pair of coordinates (X, Y).
The main advantage of this compression method is that could compress with the same ration despite the order of the colours.<<less
