how to interpret pads manual

[Marc]

How do I go from something like this:

video/mpeg:
    mpegversion: { (int)1, (int)2, (int)4 }
   systemstream: false
video/x-h264:
  stream-format: byte-stream
video/x-h265:
  stream-format: byte-stream
video/x-dirac:
video/x-cavs:
video/x-wmv:
     wmvversion: 3
         format: WVC1
image/x-jpc:

to this video_0_0100 or video_0_0041?

I take this first _0_ is the first video stream?
