I need to insert text for a media item when getting a media type of PDF by changing the GetMediaUrl method. This is for an RTE field. I went to override the MediaProvider, but found it was obsolete and replaced by the MediaManager. I created a class that inherits from the BaseMediaManager. Now I am wondering how to add that class to the pipeline. I see the one for MediaProvider, but can't figure out where to add one for MediaManager.
I found this for Media Provider:
<mediaProvider type="Sitecore.Resources.Media.MediaProvider, Sitecore.Kernel"/>
Thanks
