Macro Definition Documentation

va_deprecated_enum   = 0x80000000

Misc packed header. See codec-specific definitions.

Deprecated:

This is a deprecated packed header type. All applications can use VAEncPackedHeaderRawData to insert a codec-specific packed header

#define VA_OOL_DEBLOCKING_FALSE   0x00000000

attribute value for VADisplayAttribOutOfLoopDeblock

#define VA_PICTURE_HEVC_RPS_ST_CURR_BEFORE   0x00000010

RefPicSetStCurrBefore of HEVC spec variable Number of ReferenceFrames[] entries with this bit set equals NumPocStCurrBefore.

VA_PICTURE_HEVC_RPS_ST_CURR_BEFORE, VA_PICTURE_HEVC_RPS_ST_CURR_AFTER and VA_PICTURE_HEVC_RPS_LT_CURR of any picture in ReferenceFrames[] should be exclusive. No more than one of them can be set for any picture. Sum of NumPocStCurrBefore, NumPocStCurrAfter and NumPocLtCurr equals NumPocTotalCurr, which should be equal to or smaller than 8. Application should provide valid values for both short format and long format. The pictures in DPB with any of these three flags turned on are referred by the current picture.

Function Documentation

VAStatus vaGetDisplayAttributes	(	VADisplay	dpy,
		VADisplayAttribute *	attr_list,
		int	num_attributes
	)

Get display attributes This function returns the current attribute values in "attr_list". Only attributes returned with VA_DISPLAY_ATTRIB_GETTABLE set in the "flags" field from vaQueryDisplayAttributes() can have their values retrieved.

int vaMaxNumDisplayAttributes

(

VADisplay

dpy

)

Get maximum number of display attributs supported by the implementation

VAStatus vaQueryDisplayAttributes	(	VADisplay	dpy,
		VADisplayAttribute *	attr_list,
		int *	num_attributes
	)

Query display attributes The caller must provide a "attr_list" array that can hold at least vaMaxNumDisplayAttributes() entries. The actual number of attributes returned in "attr_list" is returned in "num_attributes".

VAStatus vaSetDisplayAttributes	(	VADisplay	dpy,
		VADisplayAttribute *	attr_list,
		int	num_attributes
	)

Set display attributes Only attributes returned with VA_DISPLAY_ATTRIB_SETTABLE set in the "flags" field from vaQueryDisplayAttributes() can be set. If the attribute is not settable or the value is out of range, the function returns VA_STATUS_ERROR_ATTR_NOT_SUPPORTED
