Hi folks. So my group and I have had trouble with Roll20's WebRTC video more or less as described above (essentially instability: particular P2P connections going blank, sometimes coming back and sometimes not, reconnecting some disrupts others, sometimes a random set of peers won't reconnect no matter what, etc). So we spent last night systematically adding one player after another to a game session, testing upload/download speeds, watching WebRTC instances accumulating (!) in chrome://webrtc-internals (thanks Karl V. for that hint), taking notes on our travails or lack of same, and contributing console logs. Hopefully seeing the same session from the perspectives of multple players could help, and the accumulation of WebRTC instances (increased by 'reconnects', adding up unevenly among players, and accumulating in a way that seems to correlate with relative levels of P2P video failure whereas bandwidth does not) seems like it might be part of the problem. We provide a full transcript and various support files here: https://www.dropbox.com/sh/wd5foc1epmqy13y/AAAeOQa
... The single zip archive contains all the other files, which are separately provided as well in case zip files make you nervous. It does seem better this time around than a couple of weeks ago, so thanks devs! In particular, we found that a workable workaround is to be verrrry patient. If a particular P2P link is broken (black video, no sound), then ONE of the affected parties should click the new Reconnect button, and then WAIT for up to 45 seconds without anybody else reconnecting or otherwise trying to fix the problem. Most often for us, in this present build, that restores disrupted connections (including those that are disrupted by the reconnect itself). If this workaround still functions on a Saturday night, then we can hold out until the real fixes are in. Hope our info-pak helps, devs. Insight and fortitude to you.
