/*
|
|
* test for tee element
|
|
* this tests for proxying of caps from tee sink to src's in various situations
|
|
* it also tests if you get a good, unique pad when requesting a third one
|
|
* which shows a bug in 0.3.2 :
|
|
* request pad, get 0
|
|
* request pad, get 1
|
|
* remove pad 0,
|
|
* request pad, get 1 (number of pads), already exists, assert fail
|
