VoLTE Setup FAIL because RTPengine build fails.

[lglhust]

Hi herlesupreeth,

I try to setup voLTE environment, according to <VoLTE Setup with Kamailio IMS and Open5GS> doc. 
(https://open5gs.org/open5gs/docs/tutorial/02-VoLTE-setup/)

In step 16. Install RTPEngine, i got build error:
And t try other version, such as  git checkout mr10.5.1, the error is the same.

Below is the output error.

codeclib.o: In function codeclib_init': ./codeclib.c:1000: undefined reference to av_register_all'
./codeclib.c:1001: undefined reference to avcodec_register_all'

when i run dpkg-checkbuilddeps, no output. Build dependencies are ok.
I appreciate very much if you could help me.

hi，herlesupreeth，

Another question, can i use open5gs HSS for voLTE without FoHSS? I see hss-cx-path.c in hss, does it works?
thanks.

I tried building RTPEngine on Ubuntu 18.04 in a docker and it worked just fine following those instructions (git checkout mr7.4.1)

Another question, can i use open5gs HSS for voLTE without FoHSS? I see hss-cx-path.c in hss, does it works?

Yes, it works. It does not have a fancy GUI like FoHSS, but can be used for basic IMS setup. I tested registration and calling and SMS.
