Following the [[dialplan]], there are two lists of extensions reserved for conferences: 130x and 139x where the last number (1-9) stands for the corresponding stage/room, while the difference between the first and last 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 <abbr title="Special information tone">SIT</abbr>, that means no stream is configured for that conference room.

=== notes and other info ===
 
* 4 HD streams were too heavy for my dual core hyperthreaded 2.4GHz laptop: it would glitch into an unintelligible paint blob
 
* 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) ==
 
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.
 
 
 
If you want to help out and fix the phone streaming, contact [[User:Xopr|xopr]].

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.

Alternatively, people traveling can join the teleconference.

It's a lot of fun if enough people join!

  • xopr (not sure which days yet)

Hint: add yourself by typing:

roadmap / Fahrplan

TBD
See CCC's Fahrplan for more info

video streams

Streams can be opened directly from Kodi, VLC or possibly your favorite media player. xopr first used a shell script to control XBMC/Kodi. Adter that we had multicast streams (including a mosaic overview) several years on a row. You can find the config here. The video links can be found here (if correctly updated): CCC streaming URIs

audio streams (phone)

We had conference audio streams (off and on) since 2012), which now has been standardized.

Following the dialplan, there are two lists of extensions reserved for conferences: 130x and 139x where the last number (1-9) stands for the corresponding stage/room, while the difference between the first and last 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.
