Dupe of Bug 1615208?

I'm hitting this problem with Nightly->Nightly sessions. i.e., not using Chrome.

I'm not able to reproduce this on 10.15.3 with the latest Nightly.

What are your media.peerconnection.dtls.version.min and max values set to?

This might be bug 1619102 if one of the Nightlies were older... A PCAP would be able to confirm.

I can't reproduce this anymore. I tried connecting from today's new Nightly (https://hg.mozilla.org/mozilla-central/rev/7ac664c145986d1cb30064d652e8198b1b3f23a3) to peers running Nightly from Friday March 6th. I also tried today's Nightly on both peers and am not experiencing the problem. All the systems have the following pref values:

media.peerconnection.dtls.version.min: 771
media.peerconnection.dtls.version.max: 772

I can still reproduce with Friday's Nightly and a machine running Beta 74. The Nightly build is failing to display the video being shared by the Beta build.

Friday Nightly: https://hg.mozilla.org/mozilla-central/rev/8ab81c8e93adff2d4187aabf1ddcfcae8bfc4e16
Beta: https://hg.mozilla.org/releases/mozilla-release/rev/c6e493873ba543907dadabb42b64208a3679d43d

Thanks. I confirmed this is bug 1619102: With a nightly build enabling the supported_versions workaround, Beta 74 <-> Nightly 75 video and audio work.

I'll uplift an NSS containing the workaround tomorrow, and the WebRTC patch is trivial.
