Cisco Cisco MXE 3500 (Media Experience Engine) Guía Para Resolver Problemas

When the affected video files are viewed in Windows Media Player, corruption in parts of the video are
observed. In both cases, the problems occur in the prefilter stage of the MXE video conversion process.

A solution is to process the corrupted video file through a different pipeline.  With an MP4 file, you can force
the preprocessor to use DirectShow instead of QuickTime.  With an AVI file, you force the preprocessor to
use QuickTime.

Create an XML file named 'manage_input_extensions.xml' with these parameters:

<extensions>

        <extension input="ts" treat−as="mpg" /> 

        <extension input="" treat−as="gxf" type="directshow" /> 

        <extension input="mp4" type="directshow" /> 

        <extension input="avi" type="quicktime" /> 

</extensions>

1. 

Copy this file to the MXE.

2. 

Remote Desktop into the MXE and copy the XML file in the C:\media directory.

3. 

Login to the MXE user interface.

4. 

Navigate to Profile Management, and choose Open Profile. Choose "Preprocessor" for Profile Class
and open the appropriate preprocessor file (in the case of Show and Share, choose the DMS_SNS_PP
file).

5. 

Navigate to the Management Input Extensions section and check the Enabled checkbox. Browse to
\\LOCALHOST\media and select the above copied XML file (manage_input_extensions.xml).

6. 

Save the profile.

7. 

Resubmit the problem video job through Show and Share. You may want to Delete any outstanding
failed jobs, if you have not already.

8. 

Note: After the job completes successfully, repeat steps four −seven, but uncheck the Enabled checkbox to
return to the default state of the preprocesser and save the changes.
