Anton,
It's difficult to do on opponent side because there I have:
1. iOS application with webrtc
2. Android application with webrtc
3. JS application with webrtc
Can you advise how to check openssl there?
But all three applications worked well when I used gstreamer version 1.16.0
on my Linux camera device.
Once I updated gstreamer version to 1.18.2 on camera device something
broke.
So I'm pretty sure issue on camera side but I have no idea how to
understand this log with dtls error and what should I fix.
Moreover on my linux camera device I have gnutls and openssl. What is used
by dtls plugin? Is it openssl or gnutls?
Thanks,
Vladimir
