Video Compression Manager test (VCMTest)
FEATURES
- The program is designed for testing of a video compression codecs
- Allows in real-time mode to meter maximum efficiently of encoder and visually to judge the worth image quality
- Matching more optimum VCM driver for compressing image data from your application
System requirements
- Windows 98, Windows Me, Windows 2000 or Windows XP
- CPU: Pentium-MMX or higher recommended, but not required
- Display card with DirectX hardware support
- DirectX 6 or higher

Testing options

- Mirror captures frame - some video codecs demand it.
Size of the captured video frames
- Frame size - width and height of the digitized frame in pixels
- List - choice of significance from the list
- Window size - to set width and height equal to a current size of the window.
- User - direct input of width and height.
- Color mode - codecs input color format
- Video compression options - specifies the codec (compressor/decompressor) and set
options specific to the selected codec.
Choices of abort of test mode condition.
- Frames limit – maximum frames
Expected parameters for the pending compression codeces:
- FPS - approximate expected capture speed.
- Frames count - approximate expected capture size.
Pending compression codeces use this information for the definition of the compression and images
quality. These values adjust experimentally.
