Didier Barvaux proposed the following answer:
Hello,

Indeed, the rohc_comp_add_rtp_port() function is deprecated because the
RTP detection callback can provide the same feature in a more generic
way.

For the RTP detection callback, look at the examples/rtp_detection.c
example. That program compresses one IPv4/UDP/RTP packet and detects RTP
streams with one RTP callback function set with the
rohc_comp_set_rtp_detection_cb() function.

The call to rohc_comp_set_rtp_detection_cb() is performed at line 277.
The rtp_detect() function is defined at line 364. The rtp_detect()
function extracts the UDP destination port and decides that the packet
belongs to a RTP stream only if its destination port equals 10042.

This an example. It should help you using the RTP detection callback
instead of the deprecated rohc_comp_add_rtp_port() function. Let me know
if it helped you.

Regards,
Didier
