no, why? moreover it's the same code as in the block of the ordinary
selection

stream_index_from_inputs() does that:

AVProgram *program = ic->programs[p];
if(program->id != programid)
   continue;

there isn't any reverse mapping from a stream to the program enclosing
it that can simplify the code in the function I added
