#include <Display.h>


Data Fields

Int numBufs
 Number of buffers the driver is to use, either allocated from the device driver or the supplied BufTab_Handle.
Display_Std displayStd
 Device driver standard to use. (see Display_Std).
VideoStd_Type videoStd
 Video standard to be used by driver. If Display_Attrs.videoStd is set to VideoStd_AUTO then video standard is determined by sysfs.
Display_Output videoOutput
 Which video output to use. If Display_Attrs.videoOutput is set to Display_Output_SYSTEM then video output device is determind by sysfs.
Char * displayDevice
 Name of fbdev or v4l2 display device to use.
Int rotation
 Degrees to rotate the display, valid values are 0, 90, 180 and 270.
ColorSpace_Type colorSpace
 Display colorspace to use. (see ColorSpace_Type).
Int width
 Video display width.
Int height
 Video display height.
Int delayStreamon
 Delay the call to VIDIOC_STREAMON until application calls Display_Put with a display buffer.
Int forceFrameRateNum
 Instruct the display to use or simulate a desired framerate. The framerate is represented as a fraction, and both forceFrameRateNum and forceFrameRateDen must be set to specify the complete value. Up to three decimal places of precision are supported.
Int forceFrameRateDen
 See forceFrameRateNum.
Int streamonDisable
 Do not execute VIDIOC_STREAMON until application calls Display_control.
