Yes, but it depends upon the media type.  I.e., it's supported only for 
streaming from files, and only for some file types.

Currently, only MPEG-1 or 2 audio (including "MP3") files and WAV audio 
files support this.

For file types to support this, their corresponding subclass of 
"FileServerMediaSubsession" will need to implement the following virtual 
functions:
         virtual float duration() const;
                 Returns the file's duration, in seconds
         virtual void seekStreamSource(FramedSource* inputSource, float 
seekNPT);
                 (Attempts to) seek within the input source.
