如何将DVR的视频提要从Web服务器获取到vb.net？

Question

we actually have something like a control center of DVR (http:/ip:port)

but i want to create my own through vb.net is there a way to get the video feed from that and get each channels for vb forms? i really don't know how to start this. thanks.

Answer 1

There is multiple ways to approach this.

1) First of I would suggest look if the company manufacturer of the DVR has their SDK(Software development kit) released since thats the best way to obtain the feed and you will have much more additional control over the DVR.

2) The other way depends if the DVR supports RTSP(Real-Time Streaming Protocol) and if it does you can request specific channel video feed based on a special url (Example: rtsp://ip:port/channel) the url depends on the DVR brand. Once your request the video feed you can play it with refrenced video plugin from 3rd party video player like for example VLC( http://www.videolan.org/vlc/ )

Those are couple of do-able solutions but in order to suggest the most well suited one I would need more information regarding the DVR.

Answer 2

Just like Knight said, best option would be asking those concerns to the company from whom you have ordered your DVR.
if you are going to use something from them externally, they should have something like that for you to tweak. in most cases, they have their own activeX controls, it gives you the easiest way possible in VB because it has its own properties that you can adjust.
