1 if frame rate is constant; 0 otherwise.

int FormatInfo::height

Height of the image in pixels.

int FormatInfo::inverted

Set non-zero if the bottom line of the image appears first in the buffer.

int FormatInfo::pixelAspectX

Pixel aspect ratio: horizontal part.

int FormatInfo::pixelAspectY

Pixel aspect ratio: vertical part.

int FormatInfo::sizeMax

Maximum size in bytes of a video frame of this format.

int FormatInfo::timescale

Number of units of time in a second.

int FormatInfo::width
