ANALOGVIDEOINFO structure

The ANALOGVIDEOINFO structure maintains information about the format of the analog video signal.

Syntax


typedef struct tagAnalogVideoInfo {
  RECT           rcSource;
  RECT           rcTarget;
  DWORD          dwActiveWidth;
  DWORD          dwActiveHeight;
  REFERENCE_TIME AvgTimePerFrame;
} ANALOGVIDEOINFO;

Members

rcSource

Source video rectangle.

rcTarget

Destination target rectangle.

dwActiveWidth

Source video width.

dwActiveHeight

Source video height (483 for NTSC, 575 for PAL/SECAM).

AvgTimePerFrame

Average time per frame in 100-nanosecond units.

Remarks

Filters using this format usually pass the video signal using a hardware-based connection rather than using memory-based transports.

An example of a definition of an analog video media type connection would be a connection of NTSC video using "M" color encoding. This would use a major media type of MEDIATYPE_AnalogVideo, a subtype of MEDIASUBTYPE_AnalogVideo_NTSC_M, and a format type of FORMAT_AnalogVideo.
