Installing R9 DirectShow Filters

A.) Unpack .zip file

After successfully downloading the R9DsFilters_xxx.zip file, unpack it. The following folder structure will be created (each DirectShow Filter resides in its own folder):

B.) Register R9 DirectShow Filters

DirectShow Filters are COM objects, therefore they must be registered first. You can register them manually or with the supplied registration application.

Manual registration
  1. In Windows taskbar select Start > Run. Dialog opens.
  2. In Open edit box enter:

        regsvr32 "[Full path to R9DsFilters folder]/R9DsFilters/EncoderVideo/R9EV.ax"

    For example, if the zip file has been unpacked directly to c:/, you should enter

        regsvr32 "c:/R9DsFilters/EncoderVideo/R9EV.ax"
        (quotation marks are mandatory!)

  3. Click OK. Confirmation box appears.

Repeat the same procedure for other 4 DirectShow Filters:

  • regsvr32 "[Full path to R9DsFilters folder]/R9DsFilters/EncoderAudio/R9EA.ax"
  • regsvr32 "[Full path to R9DsFilters folder]/R9DsFilters/Mux/R9MX.ax"
  • regsvr32 "[Full path to R9DsFilters folder]/R9DsFilters/VideoProcessor/R9VP.ax"
