Reflections on the XMPP Summit 2016
I 've been writing most of this in the airplane. I have to because my head is full of ideas and new thoughts are buzzing! Now I finally had the time to write the last bit and parts which was stuck in my brain. So I arrived in Brussels Last Wednesday (27th J...

Wrote a blogpost about Log4J and how I used couchbase to persist logs via my log4j-couchbase appender.

Hmm its becoming more and more interesting!
It looks like Hangouts currently uses Jingle (an XMPP extension created for videoconferencing) and WebRTC to get its work done. I discovered that the Google Talk plugin creates a log file in /tmp/ (at /tmp/gtalkplugin.log) that has a bunch of informative stuff. Within that log file are things like:

Sending ["latency-events","muvc-private-chat...@groupchat.google.com",...
Warning(webrtcvideoengine.cc:1439): webrtc: SetStorePacketsStatus already set, number: 600
Recving ["comment","MeetingJid=muvc-private-chat-...@groupchat.google.com"...
Jingle:Channel[audio|1|__]: NULL DTLS identity supplied. Not doing DTLS

(Note that a JID is an XMPP address. Searches for muvc-private-chat lead me to a bug filed against libjingle.)

Hangouts supports Opus:

Setting receive voice codecs:
ISAC/16000/1 (103)
opus/48000/2 (111)

It might support RTP:

SRTP activated with negotiated parameters: send cipher_suite AES_CM_128_HMAC_SHA1_80 recv cipher_suite AES_CM_128_HMAC_SHA1_80

And supports at least H.264 for video:

Selected video codec H264-SVC/640x360x30

This is all fun stuff. I wish that this had been communicated to the nerd public earlier this month. (Or does that mean that the audio-visual part of Hangouts is going to get a huge overhaul so that it doesn't actually do any of these things anymore?)
