int XSys_Init	(	XPeriph *	pPeriph,
		XVprocSs *	pVprocss
	)

This function is the system level initialization routine.

It in turn calls each of the included subsystem initialization function

Parameters

pPeriph	is a pointer to the peripherals instance
pVprocss	is a pointer to the video proc subsystem instance

Returns

• XST_SUCCESS if init. was successful.
• XST_FAILURE if init. was unsuccessful.

Note

None.

void XSys_ReportSystemInfo	(	XPeriph *	pPeriph,
		XVprocSs *	pVprocss
	)

This function reports all the IP's included in the system design.

It calls each subsystem API to report its child nodes

Parameters

pPeriph	is a pointer to the peripherals instance
pVprocss	is a pointer to the video proc subsystem instance

Returns

None

Note

None.

int XSys_SetStreamParam	(	XVprocSs *	pVprocss,
		u16	Direction,
		u16	Width,
		u16	Height,
		XVidC_FrameRate	FrameRate,
		XVidC_ColorFormat	cfmt,
		u16	IsInterlaced
	)

This function sets the video stream parameters for the Video Processing Subsystem (VProcSS).

Parameters

pVprocss	Pointer to the XVprocSs instance.
Direction	Stream direction (XSYS_VPSS_STREAM_IN or XSYS_VPSS_STREAM_OUT).
Width	Width of the video stream in pixels.
Height	Height of the video stream in pixels.
FrameRate	Frame rate of the video stream (XVidC_FrameRate).
cfmt	Color format of the video stream (XVidC_ColorFormat).
IsInterlaced	Indicates if the video stream is interlaced (1) or progressive (0).

Returns

XST_SUCCESS if successful, XST_INVALID_PARAM if the video mode is not supported.
