H263_E

  • 项目

The H263_E restricted profile contains the set of features required for support of ITU-T Rec. H.263 and a specific set of enhanced optional capabilities. Support of this profile is currently encouraged but not required. This set of features is specified by the restrictions listed for the H263_D restricted profile, except for the following additional restrictions.

Restrictions on DXVA_ConnectMode

The following restriction on the DXVA_ConnectMode structure applies when the bDXVA_Func variable defined in the dwFunction member of the DXVA_ConfigPictureDecode structure is equal to 1.

Structure Member Value

wRestrictedMode

DXVA_RESTRICTED_MODE_H263_E

Restrictions on DXVA_PictureParameters

Structure Member Value

bPicOBMC

Zero or 1

Restrictions on DXVA_MBctrl_I_HostResidDiff_1, DXVA_MBctrl_I_OffHostIDCT_1, DXVA_MBctrl_P_HostResidDiff_1, and DXVA_MBctrl_P_OffHostIDCT_1

If the bPicOBMC member of DXVA_PictureParameters is 1 and the Motion4MV variable defined in the wMBtype member of these macroblock control structures is 1, the MotionBackward variable defined in the wMBtype member must be zero.

Restrictions on Bitstream Buffers

The contents of any bitstream buffer may also contain data in the H.263 (with Annex F) video format.
