Hi Ross,

I'm having a problem with the function getNextFrame() and afterGetting(this), 
I explain:
I've modified the library to be able to get 2 input mpegTS streams from 
multicast addresses wich I can splice on demand and then stream the output to 
another multicast address.
I know I shouldn't ask you because I modified the source code but I'm having a 
small problem and I dunno have to kick it.
The software isn't for company purposes but for my  Ph.d. and will be open 
source of course.

So here is my problem.

I'm first getting the first stream :

InputSource1->getNextFrame(xxxx)  ////work
   -"-
   -"-
   -"-

//splicing asked

InputSource1->getNextFrame(xxxxx)   ///work
       afterGettingFrame1()
   {
   //algo that check where to splice in the fTo buffer
   //then copy data from fTo to fTobis //work
   //get data to fTo from input2 //work
   InputSource2->getNextFrame(xxxxxxx)   //doesn't work
   //find the right head where to start the stream.
   // work but with wrong data
   //copy paste work but with wrong data
   }

//splicing done

InputSource2->getNextFrame(xxxx)   //work
-"-
-"-
-"-
###########

Things work very well but I still don't have perfect splicing as I don't start 
the 2nd stream at the right place. The only problem is when I ask 
InputSource2->getNextFrame() while in the AfterGettingFrame1, it doesn't 
work. The function is called but the data isn't coming from the right input.
I can only successfully call InputSource2->getNextFrame(xxxxx) after the 
afterGetting(this) of the afterGettingFrame1 called by the 
InputSource1->getNextFrame(xxxx)

Do you know how I could do

InputSource1->getNextFrame(xxxxx) {
   afterGettingFrame1() {
        InputSource2->getNextFrame(xxxxxx)
                         afterGetting(this)
                       }

InputSource2->getNextFrame(xxxx)


Thanks very much for your help.

Adrian
