But there are breaks in the Fahrplan not offering live content for remote sites, if we do not provide some by ourselfs. This slot is for filling the evening break. We will meet our friends at home using our WebRTC webconferencing stuff. Feel free to bring in your equipment. The goal is to provide some "informal" congress feeling beyond congress talks. With your contributions, we perhaps will find a way to glue different remote sites together with us ... we welcome your proposals. Of course, anyone coming is invited to share howtos and insights on multisite webconferencing technologies :-) === UPDATE === Day3 session was shifted from hall 13 to our [https://events.ccc.de/congress/2015/wiki/Assembly:CCCFr CCCFr assembly]. You may find it near "Bällebad" at the very rear stage of level1. Due to the "no-cam" policy around our assembly in general, we implemented a "hot chair" setup, where you may go on-air wearing an audio headset. Group communicaton with remote sites is therefore limited (background noise in that region would detoriate this anyway) However, you are invited to join a conference session as a single person from any silent place as well. == Telepresence Technology Improvement Project (TTIP)== We do not want to fallback into Skype nor Google Hangout, unlike all those remote-connected congress talks do since years . There are stable webRTC alternatives hosted within Europe. Let´s make use of it. However, as in any live online conference setting, the main challenge is to get the remote site on hook. While congress remote talks are to be prepared within hours , a Conference Everywhere site can be prepared and tested in advance. WebRTC-based browser sessions do not require nasty Java/Flash environments nor installation of closed-source binaries. This opens a new quick-prep perspective to overcome skyping in adhoc conferencing too. === Jitsi Meet === This is the browser-based version of Jitsi. No need to install Jitsi´s thick old Java client ;-) * [https://meet.jit.si/32C3 Conference link] Sharing your Screen or some Application Window requires you to install [https://chrome.google.com/webstore/detail/jitsi-desktop-streamer/diibjkoicjeejcmhdnailmkgecihlobk Jitsi´s Desktop Streamer Extension] === Collaborate Ultra === is a closed-source webRTC conferencing service hosted in Amsterdam. We used it as state-of-the-art benchmark and found it quite stable and nice for hall-projection: No need to hangout nor skype even under professional contraints :-) Sharing your Screen-/App requires you to install this [https://chrome.google.com/webstore/detail/desktop-sharing/ajojghojfapedgfkjmhchgblmjfanggo Chrome-Extension] * [https://eu.bbcollab.com/collab/ui/session/guest/3AEBAF4335B41C8A5D37E7575590EB42 Conference Link] * [https://eu.bbcollab.com/collab/ui/scheduler/launch/session/3AEBAF4335B41C8A5D37E7575590EB42 CCCFr Assembly Hot Chair] * [https://eu1.bbcollab.com/collab/ui/scheduler/resource/session/8414452F78058973B45E27A971125403 Subtitler & Orga Chair] For mobile participation , you may want to install the [https://play.google.com/store/apps/details?id=com.blackboard.android.bbstudent Android App] via non-EU proxy. === Palava === This open source project seems to have some potential, but did not evolve remarkably since last year. It currently lacks the capability to share the screen out of the box. * [https://palava.tv/Theater Conference link] == Insights == === on webRTC multisite conferencing platforms used in this session: === Using Chromium/Chrome or Opera is recommended! Firefox v43.x faces some performance issues on how they handle multiple webRTC streams . Collaborate Ultra allows to run on current Firefox (Safari, etc.), but falls back to Flash usage. Not recommended ;) === on AV peripherals attached to desktop conferencing solutions === Regarding group audio, it was a good idea to provide the [https://cccfr.de/wiki/projekte:automixer echo-cancellation in hardware], because softwareAEC is by nature imperfect and very CPU-consuming. AEC built in sofware clients might perform sufficient for 2-3 people sitting in a silent office, but not in a hard walled empty room nor under high background noise constraints. === Reviewed Challenges === Looking back, it was challenging to adapt to the peripheral conditions. A workshop room is a good choice, if you want to have low-background noise and privacy controlled cam operation without the hazzle to keep the cam´s view background always safe. However, it is quite hard to provide "congress feeling" under such studio conditions, with just a few people in the rooms. We found it hard to setup and tear down equipment for each session within the booked timeslot. Therefore we decided to move the 3rd session from workshoproom to our assembly. There we placed in between of "informal congress atmosphere", but were challenged by the many "no-cam" activists around who required approval, that we do not transmit unwanted audio or video to the public network, but a conference room only. Thanks to anyone having contributed in that session. We will be back next year with an improved setup. <gallery mode="packed-hover" heights=200px> File:CCCFr_congresseverywhere.png|''[[https://cccfr.de/wiki/veranstaltungen:32c3 CCCFr wiki]]'' (32C3@Freiburg) </gallery> Summary: This is a minor edit Watch this page Cancel
