For examples of how to use this command, see Examples.

winsat media <-input <file name>> <parameters>

Parameters

Description

-input <file name>

Required: Specify the file containing the video clip to be played or encoded. The file can be in any format that can be rendered by DirectShow.

-dumpgraph

Specify that the filter graph should be saved to a GraphEdit-compatible file before the assessment starts.

-ns

Specify that the filter graph should run at the normal playback speed of the input file. By default, the filter graph runs as fast as possible, ignoring presentation times.

-show

Run the assessment in decode mode and show the contents of the file specified in -input in a window. By default, the assessment does not display any visible windows.

-play

Run the assessment in decode mode and play any supplied audio content in the file specified in -input using the default DirectSound device. By default, audio playback is disabled.

-encode <PRX profile file name>

Re-encode the decoded content from the file specified in -input using the Windows Media codec. PRX profile file name is the name of a file containing the PRX profile that configures the encoder. This profile is created using the Windows Media Profile Editor application in the Windows Media Encoder tool set.

System_CAPS_noteNote

The assessment will return an error if -show or -play is present in the same command as -encode.

-saveas <output file name>

Save the results of the -encode operation to the specified output file name.

System_CAPS_noteNote

The assessment will return an error if -saveas is present but -encode is not.

-v

Send verbose output to STDOUT, including status and progress information. Any errors will also be written to the command window.

-xml <file name>

Save the output of the assessment as the specified XML file. If the specified file exists, it will be overwritten.

-idiskinfo

Save information about physical volumes and logical disks as part of the <SystemConfig> section in the XML output.

-iguid

Create a globally unique identifier (GUID) in the XML output file.

-note "note text"

Add the note text to the <note> section in the XML output file.

-icn

Include the local computer name in the XML output file.

-eef

Enumerate extra system information in the XML output file.

  • The following example assesses performance when decoding the sample video file included with WinSAT and saves the results in XML format in the file media.xml:

    winsat media -input c:\windows\performance\winsat\winsat.wmv -xml media.xml
    
  • The following example assesses performance when decoding the sample video file included with WinSAT and re-encoding the video stream using the sample profile included with WinSAT:

    winsat media -input c:\windows\performance\winsat\winsat.wmv -encode c:\windows\performance\winsat\winsat.prx
    

  • Membership in the local Administrators group, or equivalent, is the minimum required to use winsat. The command must be executed from an elevated command prompt window.
