[gst-devel] Creating 1 or N src pads

I have been working on my soccer video tracking application lately (see my 
previous posts), but I know have some concerns about 1 (among many) thing:

I have my plugin receiving football video frames, and analysing them to find 
players. So my sink pad is a video type. But as output, I want to send the 
name and position of all players found in the frames. This information shall 
be used later in the pipeline to load the player image and name, and display 
that over the video (using filesrc, jpegdec, textoverlay and videomixer 
elements for ex).
My worry is how to send these information out of my plugin:
-either I create one src pad, and I create and push to it the data I need 
for each frame.
-either I create a new src pad for each player I find, and push the data for 
that player

I would rather take the first solution, and would be greatfull if someone 
would have done something similar to advice me.
