== synopsis ==
 +
The idea is, for people unable to attend the upcoming hacker congress or camp, to <s>visit the hackerspace and</s> watch the streams together on a projector screen/TV/monitor. <s>Food and drinks will be taken care of as well</s>!
 +
 +
[[User:Xopr|xopr]] created a [https://gather.town/app/iVeuxmC1wz9bpz3p/ACKspace virtual hackerspace in gather.town] (might be password protected); ask via the regular channels if needed.
 +
 +
It's a lot of fun if enough people join!
 +
Alternatively, people traveling can join the [[#audio (phone)|teleconference]].

<s>Also, we should have [[christmas tree|pixelflut]] leds (with Art-Net support) up around that time, so it's fun to show off your script/program.</s>

Streams can be opened directly from [https://kodi.tv/ Kodi], [https://www.videolan.org/vlc/ VLC] or possibly your favorite media player.
 +
Because we want to suffer (originally lower the burden of CCC's data output), we're using multicast streams (including a mosaic overview). You can find [[VLC mosaic config|the config here]].

We have conference audio streams (off and on [{{fullurl:{{PAGENAME}}|oldid=1749#Cons:}} since 2011]), which now has been standardized.

Following the [[dialplan]], there are two lists of extensions reserved for conferences: <code>130x</code> and <code>139x</code> where the last digit (1-9) stands for the corresponding stage/room, while the difference between the former and latter series is whether you are allowed to chat with other callers ("party line at 9"). See [[Telephone system:shoutcast streams]] for the [[FreeSWITCH]] configuration.

xopr had to scramble a video adapter, one of the video inputs (cable?) didn't work, and the midi control desk didn't play nice with the 30 minute old installation, but in the end it worked out fine.

The HLS streams seemed to work better in multiple occasions, but then again: rC3 [https://media.ccc.de/v/rc3-11585-infrastructure_review#t=1462 was suffering a DDoS attack] and angry mob that came with it. Also, reloading the 'level' often fixed CDN lookups, and continued the stream.

=== notes and other info ===
+
=== events in 2018 ===
* 4 HD streams were too heavy for my dual core hyperthreaded 2.4GHz laptop: it would glitch into an unintelligible paint blob
+
The [[VLC mosaic config|mosaic]] was working again after a lot of compatibility issues with newer VLC versions. More than 4 cores are recommended to process all 8 streams for 35C3.
* using a VLM config file to open multiple streams with bandwith/cpu issues causes all streams to pause upon reconnecting a stream that went out of sync. Use a separate instance for each stream
 
* the RTP stream seems to emit some type of timecode, so multiple streams are fairly in sync. Picking up on the RTP streams to create an RTP mosaic will off course delay that mosaic
 
* In 2013, [[User:Xopr|Xopr]] wrote an [[XBMC remote control script for streams]] to switch channels from within a console with just one keypress.
 
* Multicast streams didn't work on wifi (as expected), but even worse: multicast broke the wifi networks
 
  
== audio streams (phone) ==
+
* [[35C3]]
Currently, due to our [[Guerilla VoIP|temporary setup of the VoIP system]], nothing has been set-up to listen to the streams via the phone. Focus is on the [[#video streams]] for now.
+
: [[User:Stuiterveer|stuiterveer]] fixed the streams after deploying [[SpaceWorkhorse]] with an older version of VLC (lots of trial and error) and [{{fullurl:VM_server|oldid=8421}} started virtualization] of the services.

You are looking at an event that took place in the past
Event: Congress everywhere
Featured: No
State: Completed
Start date: 2022/12/30
Start time: 13:00
End date: 2022/12/31
End time: 3:00
Contact: Stuiterveer, Xopr
Kind: Conference
Location: Location::online
URL: https://rc3.world/
Fee: Free
Short description: Watch a hacker congress or camp live on a projector in the space, or listen to it via the phone.

synopsis

The idea is, for people unable to attend the upcoming hacker congress or camp, to visit the hackerspace and watch the streams together on a projector screen/TV/monitor. Food and drinks will be taken care of as well!

xopr created a virtual hackerspace in gather.town (might be password protected); ask via the regular channels if needed.

It's a lot of fun if enough people join! Alternatively, people traveling can join the teleconference.

Also, we should have pixelflut leds (with Art-Net support) up around that time, so it's fun to show off your script/program.

More info on the discussion page.

roadmap / Fahrplan

See Congress' Fahrplan or Camp's Fahrplan for the latest schedule; streams will be selected ad-hoc. remote chaos experience Farhplan

streams

video

Streams can be opened directly from Kodi, VLC or possibly your favorite media player. Because we want to suffer (originally lower the burden of CCC's data output), we're using multicast streams (including a mosaic overview). You can find the config here. The video links can be found here:

audio (phone)

We have conference audio streams (off and on since 2011), which now has been standardized.

Following the dialplan, there are two lists of extensions reserved for conferences: 130x and 139x where the last digit (1-9) stands for the corresponding stage/room, while the difference between the former and latter series is whether you are allowed to chat with other callers ("party line at 9"). See Telephone system:shoutcast streams for the FreeSWITCH configuration.

If you hear the SIT, that means no stream is configured for that conference room.

events in 2023

This year was a continuation of last year's self-hosted sessions. xopr had to scramble a video adapter, one of the video inputs (cable?) didn't work, and the midi control desk didn't play nice with the 30 minute old installation, but in the end it worked out fine. Best of all: all talks started fairly on time this time!

Attended Stats
  • 1 day of self hosted talks
  • 3 talks
  • 2 screens/projectors
  • 1 room
  • 2.7 liter of consumed chocolate milk
  • 0 cans of whipped cream 😱

  • 1 Snickers
  • 1.6 liters of Ice Tea
  • 1 Yum Yum Chicken (to complete a talk)

events in 2022

This year was completely different yet again; we streamed 0 talks and hosted a conference ourselves. The decoration and infrastructure was guerrilla style and more or less last minute, but it worked well.

Attended Stats
  • 1 day of self hosted talks
  • 8 talks
  • 2 screens/projectors
  • 2 rooms
  • 1 liter of consumed chocolate milk/Fristi
  • 0 cans of whipped cream 😱
  • 0 liters of coconut rum 😱
  • 3.3 liters of beer
  • 4.5 liters of Club Mate
  • 4 coffee
  • 1.65 liters Cola
  • 1.32 liters Fanta
  • 2.31 liters Dr. Pepper
  • 8 pizza's
  • 11 sugar cookies
  • 18 chocolate waffles
  • 8 slices of banana bread
  • 1 Sandwich Tomato & Basil (at ~4:30 in the morning!)
  • 16.8 pixels

events in 2021

This year was different again; there were no main rooms, and no audio streams available. What also changed were the stream ids: previously (mostly) numeric, now each with its own named (which doesn't help in automating)

People who wanted to watch the streams together could join the virtual hackerspace in gather.town complete with spacestate switch.

Some users were experiencing problems with the streams but most of it worked fine most of the time.

Attended Stats
  • 4 days of streaming
  • 14 HD streams
  • 2 audio streams
  • 9 rooms, 2 laveratories and one kitchen
  • ~5 days of programming (including 2 code refactors)
  • >5,7 liters of consumed chocolate milk (of 11 available)
  • >2 cans of whipped cream (of 5 available)
  • >1.5 liters of coconut rum (of 4 available)
  • 0 liters of beer
  • 0 liters of Club Mate 😱
  • 0 liters of Jolt Cola (1 liter available)
  • 6 coffee (on or about)
  • 9 internet controlled bells
  • 1 internet controlled moodlight


events in 2020

This year was a bit different; for people who want to watch the streams together, xopr created a virtual hackerspace in gather.town (might be password protected); ask via the regular channels if needed.

Also, the URL was changed to rc3.world, the incomplete schedule at fahrplan.events.ccc.de/rc3/2020/Fahrplan/, an almost complete version here and a local version that tried to parse the remote json here (after some use, the php script got an empty string back, which we had to mitigate, same for CORS and file-get-contents).

The HLS streams seemed to work better in multiple occasions, but then again: rC3 was suffering a DDoS attack and angry mob that came with it. Also, reloading the 'level' often fixed CDN lookups, and continued the stream.

Attended Stats
  • 4 days of streaming
  • 19 HD streams
  • 1 audio stream
  • 10 rooms and 2 laveratories
  • 2 days of getting the fahrplan to work comfortably
  • 7,3 liters of consumed chocolate milk
  • 1,5 can of whipped cream
  • 2,6 liters of coconut rum
  • 0.2 liters of beer
  • 0 liters of Club Mate 😱
  • 0 liters of Jolt Cola
  • 10 coffee (on or about)

events in 2019

This event was more of a dress rehearsal of getting the streams up and running on a (new) VM with the new mosaic script.

events in 2018

The mosaic was working again after a lot of compatibility issues with newer VLC versions. More than 4 cores are recommended to process all 8 streams for 35C3.

stuiterveer fixed the streams after deploying SpaceWorkhorse with an older version of VLC (lots of trial and error) and started virtualization of the services.
Attended Stats
  • 4 days of streaming
  • 8 SD streams
  • 3 days of getting the mosaic to work
  • 2 Ubuntu/VLC downgrades to resolve compatibility issues with the mosaic
  • 7 liters of chocolate milk, of which 4 liters were consumed
