Description Mathieu Duponchelle 2017-06-27 21:46:29 UTC 
The goal of this API would be to avoid requiring the use of pad-added callbacks for elements that expose sometimes pads (eg rtpbin).

I'm not entirely sure what form the API should take, but here are a few use cases:

* When rtpbin exposes a pad named "send_rtp_src_0", link it with a given pad
* When rtpbin exposes a pad named "send_rtp_src_0", link it with any pad in a given element
* When rtpbin exposes a pad named "send_rtp_src_0", request a pad named 'audio_%02x' from a given element and link them.

A problematic part might be error handling :)

Thoughts?

You can probably reuse the code from gst_parse_launch() for this. Re error handling, I guess the same as there (not-linked error at a later time if things fail). Or maybe providing a callback to the function that is called on error/success?
