This is done in latest versions of the main branch (revision 552 or later). The
mechanism uses a user-defined function callback. That callback is set with the
rohc_comp_set_rtp_detection_cb() function. The callback shall return true if
it detects that the UDP stream is one RTP stream, false otherwise.

The function is to set the callback is defined there:

An example os use is there:
