How to merge parallel(simultaneous) video streams ?

[buddhikasgj]

Apologise for this stupid question. I�m a newbie to the directshow development. I want to merge 4 simultaneous video streams with equal bitrate and frame rate into a single stream where each frame of the output stream consists of frames with similar time stamp of each the input streams. Also the output stream is to be broadcast over a network as a live stream. The algorithm i have in my mind is as follows.

 

For (each time stamp)

 

{

 

Get frames from all input streams;

 

Draw them in the output frame;

 

Add output frame in to live stream to be broadcast over the network.

 

}

 

I don�t know how far will be succeeded. So i have some questions before i start implementing this.

 

1) In order to implement this algorithm what how can I use the window sdk?

 

2) Is there any inbuilt API support for the merging phase I mentioned earlier? If yes what are they?

 

3) Any other algorithm we can use with windows sdk to achieve low delay and improve efficiency?

 

Thank you very much.
