Explanation:
My Video calls are suffering bad performance, freezing, delay and jitter. I have attached 2 files of Audio and Video data from a 5 minute video call. This uses stun.l.google.com:19302 stun server.
Data:
Notice the framerate = 9 at certain points and drops lower sometimes ( 3-5 fps for > 30 seconds ). Each datapoint was recorded every 10 seconds.
