Update of /cvsroot/datatype/wm/fileformat
In directory cvs01.internal.helixcommunity.org:/tmp/cvs-serv30018/datatype/wm/fileformat

Modified Files:
      Tag: hxclient_3_6_1_atlas
	asf_file_format_file.cpp 
Log Message:
Synopsis: The duration of a VC1/sp/ASF file duration cannot be got
rightly

Overview: time duration get from file header is 33915, preroll is 5500.
This stream have header extension object and a extended stream
properties object inside it. In extended stream properties object, start
time = 5000, end time = 37532. These two time need to be adjusted by
preroll both. Thus we can use end time - start time directly instead of
minus them separately.

Files Added: None

datatype/wm/fileformat/asf_file_format_file.cpp

Image Size and Heap Use impact (Client -Only): None
