Redirect Video Stream through asp file
Monday, November 10, 2008 3:39 AM
( permalink)
We have a video stream that has been setup and is definately working on its own from an address that is only available internally. What we need to do it read that stream via another asp file that can also be treated as a stream (i suppose bounce the stream or treat it as a proxy) this is because the second asp will be availableexternally and will allow us to control who has access to the feed at a later date. any suggestions? we were trying to use ado.stream object but were having problems getting it to work? This is the code we were trying to use to get the stream and then output it from file2.asp (code below)
<%
'Create a stream object
Dim objStream
Set objStream = Server.CreateObject("ADODB.Stream")
objStream.Open
objStream.LoadFromFile "[link=http://123.123.123.123/mystream.cgi?camera=1][color=#0000ff]http://123.123.123.123/mystream.cgi?camera=1[/color][/link]"
'Output the contents of the stream object
Response.ContentType = "video/x-ms-wmv"
Response.BinaryWrite objStream.Read
'Clean up....
objStream.Close
Set objStream = Nothing
%>
thanks for any help in advance!!

Take a look at Server.Transfer. you can use that to treat any public facing asp page as a sentinal for internal files. The client will never see the address change

Ive just been informaed that the camera stream we are trying to access is on an internal ip address BUT is on a different pyhsical box so the Server.Transfer wont work. Have you got any other ideas?

Are these all on the same network or is the other computer on a different site? Are you using your current one as a proxy or something? If all on the same network I would assume you could still use Server.Transfer since a mapped location works basically the same.

my collegue said the following: The source (axis webcam) and the asp (on webserver) are both on the same network yes. The webcam is a unix box, so while we could maybe do some stuff, network shares across different operating systems I think is a tricky scenario? (not my expertise, so might have misunderstood something). We don’t really have axis to the underlying copy of unix anyway, so just the webstuff.

If they are on the same network then how are the other window machines connected to the unix box then? Is everything being run through SAMBA or something?

thats how we currently view the stream - this was the code we were given and it works fine internally. We cannot modify how the .cgi file works so we need to make the url available externally and add a user logon page. I can make a logon system thats fine but i still am unsure how to allow this stream to be available externally. itried using the .asp file posted at the very top of this page but it just hangs (presumably as its trying to download the whole stream and therefore never updates the screen but timesout) I was thinking i need to proxy it through an asp file or something?? I have access to PHP or ASP so i can develop in either but ive never done something like this and im finding it hard to get a solution! Hope you can help / this makes it clearer what i require Cheers, Cyf

So right now is it possible to view the webpage that has the code you just posted without logging in?

Yes, there is basic authentication so it prompts for username and password guest,guest which i can either set using parameters or it will prompt for then automically. The main authentication is going to be added to the proxy page when ive got the basics working! I've started doing this in PHP too as im a little more familiar with the language maybe someone can help with that as im a little bit further on with it!
