How to Find a Codec?
If you knowthe name or ID (knownas a FourCCidentifier forvideocodecsora WaveFormat
identifierforaudiocodecs) of the codec,youcan directlysearchthe codecwiththem.Or,youcan
visitthe official website of the codecmanufacturer todownloadthe newestversion.
Note:
Be cautious when installing codecs fromonlineresources,especially fromsomeof the free codec
packsthatclaim to include codecsfroma variety of companiesororganizations. Thereareknown

7. compatibilityissueswith someof thecomponentsin thesecodec packs,which can cause serious
playbackproblemsin media players,systemcrashes,and makeit difficult forMicrosoftSupportto
diagnoseand troubleshoot problems.
Thus,you are strongly recommended notto install thosecodecs and removethemif you are having
problemswiththe media players. You are suggested to only install codecs,filters, and plug-insfrom
reliable channelslike the provider’sofficialweb page.Besides,you can create a systemrestore point
beforeinstalling thosecodecsin case you can return to the previousworking statewhen necessary.
In addition,yoursystemadministratoratworkmightuseGroup Policy to preventyou frominstalling
newcodecs.
If you don’tknoweitherthe name orthe ID of the missingcodec,youcan figure outwhichcodec is
usedto compressthe targetfile using the followingmethod.
Firstly,youcan playthe file withWindowsMediaPlayerif possible.
1. While playing,right-clickonthe file inthe libraryandchoose Properties.
2. In the Propertieswindow, gotothe File tab.
3. Under the File tab,checkthe Audio codecand Videocodec of the file.

8. Alternatively,youcanplaythe target mediafile withotherplayersandview itspropertiesforcodec
informationif WindowsMediaPlayerfailstoplaythe file.
Secondly,youcan relyon a codecidentificationtool tohelpyourecognize the audioorvideocodec
of the targetfile.
Besides,youmayknowthe formatof a file bycheckingthe file name extensionlike.wma (Windows
MediaAudioformat),.wmv(WindowsMediaVideoformat),.mp3,or.avi.Yet,manyapps create
fileswithcustomfile extensions andanyone canrename afile togetherwithitsextensionwithout
changingthe file format.
Moreover,sometimes,evenif youhave alreadyinstalledthe missingcodec,youstill cannotplaythe
target file.Itmay be due to that youhave installedthe wrongbitof codec.Codecscan be writtenfor
32-bit or 64-bit operatingsystems.If youinstall a32-bitcodec onyour 64-bit OS,it won’twork.
Many oldercodecsare onlyavailable in32-bit.If the codecproviderdoesn’tspecifythe bitof the
codec,it tendstobe 32-bit.
HEVC Codec Windows 10
By default,Windowsdoesn’thave the HEVCcodecincluded.So,itdoesn’tsupportHEVC-encoded
files. Yet,justasmentionedabove,youcandownloadandinstall the HEVCcodecpack onyour
computerandenable WindowsMediaPlayer orMovies &TV to playthe HEVC file.
You can search forHEVC inMicrosoft Store.Withinthe numeroussearchresults,youcanfind HEVC
videocodecpacks,HEVC videoplayers,HEVCvideoextensions, HEVCvideoconverters,etc.Thus,
youhave several choices:
 Install the HEVCcodec pack andplay the HEVCfile with aWindows built-inmediaplayer.
 Downloadandinstall anHEVC playertoopenthe mediafile.
 Addan HEVC video extensiontoplayHEVCfiles.
 ConvertHEVCfile toa Windows-supportedformatby HEVCconverter.
