Boostada maanta, waxaan isku dayi doonaa inaan fahanno sababta Microsoft DirectX 9 aysan ula shaqeyneynin bandhigyada Miracast on ^(Miracast)Windows 10 oo wata Windows Display Driver Model ( WDDM ) 2.0 darawalada sawirada Windows 10 .

Ka hor inta aynaan u gelin mawduuca saxda ah, aynu eegno sharraxaadda kooban ee Miracast , WDDM iyo Microsft DirectX , si ay uga faa'iidaystaan ​​akhristayaasha cusub.

Waa maxay Microsoft DirectX?

Microsoft DirectX  waa ururinta barnaamijyada codsiyada interneedka ( APIs ) ee loogu talagalay maaraynta hawlaha la xidhiidha warbaahinta badan, gaar ahaan barnaamijyada ciyaaraha iyo muuqaalka, ee  goobaha Microsoft  . Asal ahaan, magacyada API-yadaan^(APIs) dhamaantood waxay ku bilowdeen Direct , sida  Direct3D ,  DirectDraw ,  DirectMusic ,  DirectPlay ,  DirectSound , iyo wixii la mid ah.

Magaca DirectX  waxa loo sameeyay erey gaaban oo dhan API-^(APIs) yadan (  X  u taagan magacyada API ee gaarka ah) isla markiiba waxa uu noqday magaca ururinta.

Waa maxay Miracast?

Miracast waa borotokool muraayad-muraayad ah^{(Miracast is a screen-mirroring protocol)}  kaas oo kuu ogolaanaya inaad wax ka sii darto qalabka Android ama kombiyuutarka Intel ee u dambeeyay TV-gaaga. Wax kasta oo aad ku aragto shaashadda yar ayaa ka muuqan doona shaashadda weyn. Haddii wax walba si sax ah u wada socdaan, ma jiraan wax dib u dhac ah, taas oo ka dhigaysa mid ku habboon daawashada fiidiyowyada ama isticmaalka software wax soo saarka, inkastoo aysan ahayn mid la isku halleyn karo oo ku filan in lagu socodsiiyo ciyaaraha intooda badan.

Waa maxay Moodeelka Dareewalka Bandhigga Daaqadaha^(WDDM) ( WDDM^{(Windows Display Driver Model)} )?

Qaabka Darawalka Bandhiga Daaqadaha (WDDM)waa naqshadda naqshadaynta darawalnimada garaafka ee darawallada kaararka fiidyowga ee ku shaqeeya  noocyada Microsoft Windows  ee ka bilaabma  Windows Vista .

Waa beddelka kii hore ee  Windows 2000  iyo  Windows XP  bandhig darawalka moodeelka XDDM/XPDM waxaana looga golleeyahay in lagu suurtogeliyo garaafyada waxqabadka wanaagsan iyo shaqeynta garaafyada cusub iyo xasilloonida. Dareewalada ku soo bandhigay Windows Vista iyo  Windows 7 waxay dooran karaan inay u hoggaansamaan WDDM ama XDDM . Markii XDDM laga saaray  Windows 8 , si kastaba ha ahaatee, WDDM waxay noqotay ikhtiyaarka kaliya.

WDDM ayaa looga baahan yahay samaynta Windows DWM ( Maamulaha Windows Desktop^{(Desktop Windows Manager)} ) iyo isku xidhka wadayaasha qalabka ee Direct3D 10 .

Diyaaradaha dhaxalka ah ee DirectX 9^{(DirectX 9)} kuma shaqeeyaan bandhigyada Miracast

Microsoft DirectX 9 dayuuradaha dulsaarka dhaxalka ah kuma shaqeeyaan bandhigyada Miracast Windows 10 oo wata darawalada sawirada ^(Miracast)WDDM 2.0 . Codsi kasta oo isku daya inuu isticmaalo dulsaar dhaxalgal ah inta uu ku shaqaynayo bandhiga Miracast wuxuu helayaa fariin qalad ah.

Sida qaladkan loogu sheego isticmaalaha waxay ku xidhan tahay sida uu codsiga u maamulo khaladka. Isticmaalayaashu waxay arki karaan mid ka mid ah calaamadaha soo socda marka ay la kulmaan arrintan:

• Codsigu wuu xidhan yahay.
• Codsiga wuu burburay
• Farimaha khaladka ah waxaa muujiya arjiga isku dayaya inuu isticmaalo dulsaar dhaxalgal ah.
• Dib-u-soo-celinta fiidyowga waa madhan.

Waxaad la kulmi doontaa arrintan sababtoo ah marka loo eego Microsoft - dulsaarka dhaxalka ah laguma taageero Modelka Darawalka Darawalka ee Windows^{(Windows Display Driver Model)}  ( WDDM ) 2.0 darawalada sawirada Windows 10 .

DirectX 9 legacy overlay planes don't work on Windows 10

In today’s post, we will attempt to understand why Microsoft DirectX 9 legacy overlay planes don’t work with Miracast displays on Windows 10 with Windows Display Driver Model (WDDM) 2.0 graphics drivers on Windows 10.

Before we dive into the subject matter proper, let’s take a look at the brief description of Miracast, WDDM and Microsft DirectX, for the benefit of our new readers.

What is Microsoft DirectX?

Microsoft DirectX is a collection of application programming interfaces (APIs) for handling tasks related to multimedia, especially game programming and video, on Microsoft platforms. Originally, the names of these APIs all began with Direct, such as Direct3D, DirectDraw, DirectMusic, DirectPlay, DirectSound, and so forth.

The name DirectX was coined as a shorthand term for all of these APIs (the X standing in for the particular API names) and soon became the name of the collection.

What is Miracast?

Miracast is a screen-mirroring protocol that lets you broadcast anything from an Android device or recent Intel computer to your TV. Whatever you see on the small screen will appear on the big screen. If everything syncs up properly, there’s almost no lag, making it ideal for watching videos or using productivity software, although it’s not quite reliable enough to run most games.

What is Windows Display Driver Model (WDDM)?

Windows Display Driver Model (WDDM) is the graphic driver architecture for video card drivers running Microsoft Windows versions beginning with Windows Vista.

It is a replacement for the previous Windows 2000 and Windows XP display driver model XDDM/XPDM and is aimed at enabling better performance graphics and new graphics functionality and stability. Display drivers in Windows Vista and Windows 7 can choose to either adhere to WDDM or to XDDM. With the removal of XDDM from Windows 8, however, WDDM became the only option.

WDDM is required for rendering the Windows DWM (Desktop Windows Manager) and device driver interfaces for Direct3D 10.

DirectX 9 legacy overlay planes don’t work with Miracast displays

Microsoft DirectX 9 legacy overlay planes don’t work with Miracast displays on Windows 10 with WDDM 2.0 graphics drivers. Any application that tries to use legacy overlays while it’s running on a Miracast display receives an error message.

How this error is communicated to the user depends on the application’s handling of the error. Users may see any of the following symptoms when they encounter this issue:

• The application hangs.
• The application crashes.
• Error messages are displayed by the application that’s trying to use legacy overlays.
• Video playback is blank.

You’ll experience this issue because according to Microsoft – legacy overlays aren’t supported with Windows Display Driver Model (WDDM) 2.0 graphics drivers on Windows 10.
