Video on Demand: http or rtsp ?

[francescoIT]

Hi all !
May be a stupid question, but:
why is useful use VLM for VOD ? I mean can't we just put media inside a web server (like Apache) and open them via VLC ?
If I place a media in a web server I can open it through this mrl:
http://servername:port/filename.ext

and it work very well (fast foward and rewind)

while if I use VLM i need such string:

rtsp://servername:port/vod_name

but the stream does not work well, I mean I got a lot of problem with fast-fowarding (simply Id does not work)

Any help/idea ?

May be I am missing something ?

Thanks a lot

Http streaming means that the source file is accessible (downloadable) by the users..
With Rtsp users can play the stream while the server sends them the packets (real time).. but in vlc this protocol doesn't work very well, there are some issues with seeking functions, and vlc doesn't support rtsp interleaved that is usefull if the client is nat/firewalled
