How

[Rahul Nikose]

Can any body explain me following
 
 If my pipeline consist of filesrc --> demuxer -->.....
  I want to demuxer to pull data from filesrc (which will open file) any data i.e random access..
 How communication establish initially... if my demuxer's sink pad are scheduling in pull base mode then is it filesrc
 will open file and push initial data to demuxer ,then afterward demuxer pull data from filesrc
                                 or
 is it my demuxer who will request filesrc to open file  i.e.   Is  everything will start from demuxer... who will first request
filesrc to open file and afterward access it.. ?

   One more thing ....in either case filesrc will open file....is it anyway possible to get me  file handle (return by fopen() )
in next element i.e inside demuxer where demuxer will use that handle to do some more activity... :)

Thank you very much...have very nice day .. :)

Even if you could, this is totally against the design. What exactly do
you want to achieve?

  The data flow will be controled by the demuxer. The actual opening of
the file is done in filesource (when going from READY to PAUSED).

   No, you can't get the handle. What more do you want to do apart from
random-access to the contents ?
