[Freeswitch-users] FEC feature in mod_opus

[Kamil Nigmatullin]

Hi Dragos,
I tried to use your patch but have no luck with compiling it.

I clonne stable 1.2 and then replace mod_opus.c with your code. Maybe do
you know how to fix it?

This is what I get:
d_opus/mod_opus.c  -fPIC -DPIC -o .libs/mod_opus.o
/usr/src/freeswitch/src/mod/codecs/mod_opus/mod_opus.c: In function
'switch_opus_fmtp_parse':
/usr/src/freeswitch/src/mod/codecs/mod_opus/mod_opus.c:155:18: error:

/usr/src/freeswitch/src/mod/codecs/mod_opus/mod_opus.c: In function
'switch_opus_decode':
