I’ve added logs about negotiated caps for:
PIPELINE#1: gst_parse_launch("audiotestsrc ! audioconvert ! audioresample ! alawenc ! rtppcmapay ! udpsink host=192.168.1.6 port=5011", &error);
and for this one:
PIPELINE#2: gst_parse_launch("osxaudiosrc ! audioconvert ! audioresample ! alawenc ! rtppcmapay ! udpsink host=192.168.1.6 port=5011", &error);
I’ve tried to extract from logs section regarding capability negotiated starting form source ending on alawenc, this is the result:
