[streaming] openRTSP cannot receive WMV files correctly?

[luwei at tju.edu.cn]

I settled up the Windows Media Server on a local PC, then tried to download some
wmv files from the server with openRTSP from livemedia. After studying the VLC
code, I used -S 4 parameter to receive the stream in simple mode. However, the
recorded file is quite DIFFERENT with the original file on the server. I noticed
that only one subsession could get the stream. For ASF files, the file is the
same
as the original one except for lacking of the header. For WMV files, the recorded
ones differed in both packet headers and AV contents and could not be decoded.

I am puzzled how VLC which also uses the live555 library can play the medias on
Windows Media Server. Should I use some other parameters when running openRTSP
for
a correct reception of streams?
