QSV-FF encde nt utilizing render engine, except next 2 cases: Target Usage equal t 1 and NumRefFrame equal t 3. ARGB used as input. Nt supprted mfxextcdingoptin3::adaptivemaxframesize. MaxQP with MaxFrameSize nt wrking, MaxQP will have mre pririty and MaxFrameSize will be vilated. Frames fr different views in single AU in MVC encder must be prvided t encder in rder specified by mfxmvcviewdependency. MFX_EXTBUFF_AVC_REFLIST_CTRL and MFX_EXTBUFF_CODING_OPTION_SPSPPS external buffers are nt supprted by MVC encder. MVC encder supprts MFX_PROFILE_AVC_STEREO_HIGH nly. H.264 encder in sftware implementatin desn t supprt prcessing f mfxextpicturetimingsei template. During initializatin 0xFFFF values will be reset t default values. In runtime 0xFFFF values will be put t bitstream as is. H.264 encder in sftware implementatin has next limitatin: the value NumberOfPrcessrs * Frame_Width * Frame_Height * 2.5 shuld nt be greater than 2Gb if using CABAC, 1 GB if using CAVLC. RefPicMarkRepSEI syntax is nt supprted by MVC encder. Knwn limitatins fr H.264 Multiple-Segment Encding: Hardcded HRD parameters: bit_rate_scale = 0, cpb_size_scale = 3. Encded bit_rate_value_minus1, bit_rate_scale represent BitRate frm riginal SPS within precisin f Kbps (maximum supprted BitRate is 2^16 1 Kbps).

17 Target usage 7 f H.264/MVC encders in sftware implementatin is knwn t have a nn-mntnic quality versus bitrate dependency. MVC encder ignres any user SEI messages fr the dependent view. The lk ahead bitrate cntrl mde may prduce nn HRD cmpliant encded streams. mfxextcdingoptin2::lkaheadds currently supprts nly MFX_LOOKAHEAD_DS_OFF and MFX_LOOKAHEAD_DS_2x, MFX_LOOKAHEAD_DS_4x will give the same result as MFX_LOOKAHEAD_DS_2x. MFX_LOOKAHEAD_DS_OFF is the default value fr target usage 1 and 2. MFX_LOOKAHEAD_DS_2x is the default value fr target usages 3 7. H.264 and MVC encders may nt bey the minimum cmpressin rati required by the Blu-Ray*/AVCHD* specificatins when the requirement is strnger than in H.264 standard. The value reprted via mfxextencdercapability::mbpersec may be bigger than the actual maximum prcessing rate f the encder. T change encding parameters n the fly with Reset() functin w/ IDR insertin applicatin shuld drain all the buffered surfaces frm encder. Otherwise encder may demnstrate undefined behavir after Reset. Call f Reset which starts new sequence (inserts IDR) will drp HRD cnfrmance ver the inserted IDR (CPB remval cunter will be set t 0 in the IDR Picture Timing SEI). HRD vilatins are pssible in specific scenaris (e.g. massive frame skipping). Encder prhibits increase f DPB size (NumRefFrame) via Reset functin even if new size is lwer than initializatin value. Reset functin will return MFX_ERR_INCOMPATIBLE_VIDEO_PARAM n any attempt t increase NumRefFrame. Target usage MFX_TARGETUSAGE_BEST_SPEED may prduce better bjective quality than MFX_TARGETUSAGE_BALANCED. Encder may nt insert PCM macrblcks when required. Encding f specific (cmplex) cntent with huge bitrate (which makes encder insert many PCM MBs) may cause a GPU hang n Haswell. Reset functin isn t supprted fr LkAhead BRC mdes. Reset functin desn t return an errr when called tgether with LA BRC. Result f such Reset call is undefined. B-pyramid isn t supprted tgether with HRD cmpliant Lk Ahead BRC (MFX_RATECONTROL_LA_HRD) and Lk Ahead BRC with sliding windw cntrl (MFX_RATECONTROL_LA and WinBRCMaxAvgKbps and WinBRCSize). Careful memry/resurce planning is needed when using Lk Ahead BRC due t strage f pre-analyzed frames. 1:N and N:N transcding use cases are especially demanding fr memry. When external Lk Ahead BRC is used in transcding pipeline which includes Frame Rate cnversin (FRC), FRC in the pipeline shuld take place befre external Lk Ahead. Otherwise encder may return errr MFX_ERR_UNDEFINED_BEHAVIOR frm EncdeFrameAsync calls. *Other names and brands may be claimed as the prperty f thers.

18 Trellis ptin can be enabled nly n lwer target usages, n sme f thse it is enabled by default but can be switched ff. Exact implementatin details are hidden and may change with time and between platfrms. Use f Query functin t retrieve actual supprt is strngly recmmended. SkipFrame feature has the fllwing limitatins: If GOP has nly P frames, arbitrary P can be skipped. When skipped, it is made nn-reference. If GOP has B frames, nly nn-reference B can be skipped. Sme fails can happen during encding in case f reinitializatin f encder in ne sessin with DirectX11. On specific cntent and height bitrate encder desn't always re-cde MB as PCM when its size exceed allwed by standard. Encding using VBR and dynamically adjusted the MaxFrameSize n a perframe basis algrithm may leads t HRD buffer underflw and quality artifacts. Max bitrate vilatins are pssible in case f using VBR and specific paylad. Fr RGB input in case f unspecified mfxextvidesignalinf::matrixcefficients r nt equals 1 will be used BT.601, if mfxextvidesignalinf::matrixcefficients = 1 - BT.709. Actual list f supprted cnversins may depend frm versin f driver. On 7 th Generatin Intel CreTM and driver mfxextvidesignalinf::matrixcefficients will be ignred. Fr HW BRC: supprted nly WinBRCSize <=1 sec. Enable/disable repartitin check is nt supprted in case f LwPwer encder mde. Fr explicit weighted predictin since 7 th Generatin Intel CreTM supprted nly LumaLg2WeightDenm / ChrmaLg2WeightDenm = 6 r 0. Encding fails culd be bserved n 8 th Generatin Intel CreTM and Pentium platfrms in case f ExtBrcAdaptiveLTR feature is turned n. Fails will be fixed in the nearest graphics driver updates. MPEG-2 decde limitatins: MPEG-2 Vide decder returns MFX_ERR_UNDEFINED_BEHAVIOR instead f MFX_ERR_MORE_DATA when part f sequence header is absent and MFX_BITSTREAM_COMPLETE_FRAME flag is set. Decder des nt supprt bitstreams with reslutin bigger than 2096x2096. MFXVideDECODE_Init returns MFX_ERR_UNSUPPORTED n such bitstreams. Decder des nt supprt MPEG-1 bitstreams. It is interpreted as crrupted MPEG-2 bitstream. MFXVideDECODE_Init returns MFX_ERR_NONE and MFXVideDECODE_DecdeFrameAsync returns MFX_ERR_MORE_DATA until valid MPEG-2 bitstream is fund. Sequence headers are skipped if reslutin exceeds maximum supprted values (2096x2096) r level/chrma are invalid. It affects MFXVideDECODE_DecdeFrameAsync. *Other names and brands may be claimed as the prperty f thers. Page 18 f 22 OpenCL and the OpenCL lg are trademarks f Apple Inc. used by permissin by Khrns.

19 mfxdecdestat.numframe that is returned frm GetDecdeStat functin is less by 1 than actual cunt f decded frames if GetDecdeStat is called after buffered frames are returned. VC1 decde limitatins: VC1 decder can t set crruptin flag in P,B-Frames if previus I-Frame was missed. VP9 encde limitatin: BRC desn't supprt cnfiguratins where amunt f bits fr frames in base layer is less than amunt f bits fr frames in upper layers. Encder may prduce stream with bitrate f base layer prprtinally bigger r equal t upper layers. Distance between base layer frames mre than 8 may leads decrease f cmpressing effective. VPP cmpnent has next limitatins: Cmpsitin has issues after reset with input system memry usage, input system memry nt recmmended fr use with cmpsitin if resetting cmpsitin pipeline required. MFX_FRCALGM_DISTRIBUTED_TIMESTAMP is unsupprted by InverseTelecine and Deinterlace (60i->60p) VPP filters. mfxextvppauxdata is deprecated. VPP::Query in sftware implementatin mistakenly indicates supprt fr MFX_FRCALGM_FRAME_INTERPOLATION while it is actually nt available. VPP scaling in sftware implementatin may prduce slightly blurred frames fr RGB32 interlaced cntent. VPP Image Stabilizatin and FRC Interplated filters will be deprecated and nt recmmended fr use due t result image quality and prduct quality assciated with these filters. When De-interlace and FRC filters used in pipeline MFX_DEINTERLACING_BOB will be used by default, if nt specified explicitly t use MFX_DEINTERLACING_ADVANCED. MFX_FOURCC_YV12 supprted nly via sftware fallback with DirectX* 11.1 interface. VPP in sftware implementatin always uses simple FRC algrithm based n repeat/drp frames and ignres MFX_FRCALGM_FRAME_INTERPOLATION flag. ADI may prduce clr artefacts n frame preceding a scene change. ADI may prduce clr artefacts in case f harmnic mtin (repeated pattern and mtin magnitude is the same as the peridic f repeated pattern). Multiple VPP filters being cmbined in ne sessin may prduce utput that is nt bit-exact with the utput frm the same VPP filters that are split by separate sessins, but the difference des nt affect visual quality. Frames with interlaced cntent must have CrpH multiple f 4. Otherwise, VPP may prduce clr artefacts n the bttm lines. *Other names and brands may be claimed as the prperty f thers.

20 De-interlacing is supprted fr NV12, YUY2 frmats nly. Once enabled at the Init stage VPP de-interlacing fr BOB mde is nt disabled autmatically if applicatin prvides input frames with picstruct set t MFX_PICSTRUCT_PROGRESSIVE. 1 st frame is dubled during 30i->60p de-interlacing fr MFX_DEINTERLACING_BOB and MFX_DEINTERLACING_ADVANCED_NOREF mdes. MFXVideVPP_GetVideParam des nt update values in attached extended buffers, except VPP_DO_USE. MFXVideVPP_Reset culd return errr if additinal memry allcatin is required based n prvided vide parameters (changed type f clr r frame rate cnversin fr example). The applicatin shuld clse VPP cmpnent and then re-initialize it in this case. See MFXVideVPP_Reset in SDK API Reference Manual fr mre details abut pssible return statuses. Multiple RGB4 surfaces with PixelAlphaEnable enabled culd give pr visual quality after cmpsitin n the same area with verlapping. Deprecated MFX_EXTBUFF_VPP_PICTSTRUCT_DETECTION enumeratr. VPP Mirrring in pipeline with vide t vide memry in/utput patterns can be supprted nly withut any ther filters, in/ut memry patterns cntaining system memry is supprted with any ther legal filters cmbinatin. ADI with dubled framerate there is an issue when first 3 frames cpied instead f 2. On 6 th generatin Intel Cre and Xen E3 v5 Tempral Denise enabled this can affect sme result f denise n scene change and after reset with changed denise factr. mfxextvppsignalinf has t be attached t surface with NV12 frmat nly when clr cnversin dne. Rtate + Detail/PrcAmp in cmbinatin affect each ther, thus result can different cmparing running filters separately and in ne call. Cmpsitin f mre than 8 DirectX* 11 surfaces alng with alpha blending and verlapping gives pr visual quality. The reasn is the last picture blend with backgrund. The Media RAW Acceleratr Plug-in has the fllwing knwn limitatins: Current versin supprts sessins nly initialized as MFX_IMPL_HARDWARE, MFX_IMPL_HARDWARE_ANY, MFX_IMPL_VIA_D3D11, MFX_IMPL_VIA_D3D9. Sftware fallback implementatin is nt ptimized thus perfrmance is very pr. Sftware fallback can be nt bit exact with GPU ptimized versin. Current versin supprts nly system memry as input memry type. Current versin supprts nly system memry as utput memry type fr MFX_FOURCC_ARGB16 and MFX_FOURCC_ABGR16 clr types. Current versin f plugin desn t supprt paque memry type. Additinal Intel Media SDK sessin must be created t use traditinal VPP features f Intel Media SDK HW Library.
