 The CCC Berlin setup is currently an experimental setup. We currently run there an JVC HM300 cammera which has IP based streaming build in which we feed to voctomix. We also have there a tronsmart grabber box which also can stream to voctocore. The CCC Berlin setup is currently an experimental setup.

 +== David's setup
 +
 +This is probably the cheapest vocto setup you can find. All the sources run on separate devices (!) and are encoded into a single stream by our server.
 +
 +* [[https://github.com/DavidVentura/voctomix/tree/dev/prod_scripts]]
 +
 +=== Sources
 +
 +* Camera 1: Raspberry Pi with camera.
 +* Camera 2: Raspberry Pi with camera.
 +* Slides: Lenkeng LVK373a (see: [[https://blog.danman.eu/new-version-of-lenkeng-hdmi-over-ip-extender-lkv373a/|reverse engineering]])
 +* Audio: Odroid U2 connected via USB to our audio mixer
 +
 +=== Sources & Voctocore
 +
 +==== Producers: 
 +* Camera 1: gstreamer with rpicamsrc serves an h264 stream with matroska container with tcpserversink
 +* Camera 2: gstreamer with rpicamsrc serves an h264 stream with matroska container with tcpserversink
 +* Audio: Feeds the audio directly to vocto in the desired format
 +* Slides: Unicast/multicast to the network
 +
 +==== Consumers:
 +
 +On the server I host voctocore I run the following scripts
 +* Camera 1: Grab data from the camera1 tcp server, decode it and feed it to vocto
 +* Camera 2: Grab data from the camera2 tcp server, decode it and feed it to vocto
 +* Slides: Connect to mcast group, decode and feed it to vocto
 +
 +=== Hardware
 +* Audio mixer: Behringer Xenyx Q502usb
 +* Microphones: (2x) Skp Uhf271
 +* Grabber: Lenkeng LVK373a
 +* Server: i7 4790 + Gigabyte motherboard + 8GB Ram
 +
 +=== Misc
 +
 +* We have our custom slides software, so the Camera1 doubles as a presenter for slides, which is why it is hooked to an active hdmi splitter, and the splitter is connected to both the projector and the grabber.
 +* With our custom slides software, we have a dumb android app on a tablet that lets the speaker draw over the slides.
 +* The camera 1 is fixed and has 2 cheap [[http://www.conrad.com/medias/global/ce/2000_2999/2000/2090/2090/209089_LB_00_FB.EPS_1000.jpg|servos]] to make it move.
 +* The camera 2 is on a tripod powered via PoE.
