/* this test checks that gst_pad_link takes into account all available
|
|
* information when trying to link two pads.
|
|
* Because identity proxies caps, the caps in the first and second link
|
|
* must be compatible for this pipeline to work.
|
|
* Since they are not, the second linkig attempt should fail.
