Dear Rémi Denis-Courmont,
Thank you for the hint. I didn,t know that vlc also has its own md5 
implementation. But it is just a "not so strong MD5 hashing" as written 
in the md5.c file. The one I used is from live555 and at least it is 
not  noted  with that :-)
Anyway my first try to use the md5 of vlc failed. I will try to figure 
it out. And I will try to make use of it in the RTSP authentication 
soon. In any case, the object  file  of the md5 from live555 is already 
included in vlc. So  it is not because  of my implementation, we have 
duplication of the md5 in vlc.
Best regards
