Can’t convert FLV to MP3 due to a vcen.dll error?

When using Total Video Converter on a web server to convert Nellymoser FLV (but not MP3 FLV), you may encounter an error in vcen.dll. You cannot usually invoke the command line version of Total Video Converter directly from your web application. You must make a Windows Service that performs the conversion. We made a service that converted all Nellymoser FLV files written to a specific folder to MP3 files. We were able to do large number simulations conversions this way.

For more information on Total Video Converter see my tutorial on using the Total Video Command line application to convert Nellymoser FLV files to mp3 or wav files.

I will post an example application with tutorial, that walks you through the entire process of doing the Nellymoser FLV to MP3 conversion with Total Video Convert and setting up the Windows Service as soon as possible.
