Hello again. More progress.


Successfully tested full gear setup, now very close or identical of what 
we will be actually using for LAC19:


=== SERVER SIDE AND SOURCES ===

   (infrastructure)

- cm-jam with Icecast2 software as the main streaming server.

- cmn58 (workstation) with OBS as the main/only source streaming server 
feeding Icecast (via FFMPEG sending A/V via icecast:// protocol)


   (audio and video of the venue / presenter)

- Camera connected via HDMI to capture card #1, and card connected via 
USB to cmn58

- 1 MIC connected to Tascam 2x2 audio interfaces, connected to USB to 
cmn58

- OSB configured to use directly 2x2 interface to potentially mix 
several channels of audio inputs from the audio card


    (presentation, desktop sharing, video playback... from presenter's 
laptop)

- Laptop HDMI output connected to an HDMI splitter

- HDMI splitter output #1 connected to an HDMI extender over Ethernet

- HDMI splitter output #2 could be the one to connect to the projector 
for the audience

- Receiver side from the HDMI over Ethernet connected to capture card #2

- Capture card #2 connected to cmn58 to feed laptop's video feed into 
OBS


=== CLIENTS ===

- 2 laptop clients, mine locally and another remote watching the live 
streaming and receiving audio and video.

- 1 mobile phone client watching the live streaming and receiving audio 
and video.


=== SCENES ===

   Audio:

- Mix coming from Tascam 2X2


   Video:

Switching from:

- cmn58 own Desktop feed

- Camera live video feed

- Laptop's live HDMI output feed



I already talked to Dave; we will be doing live tests soon, maybe this 
evening and/or maybe some of tomorrow's events around here (setting up 
things in the Stage as it will/could be in Dinkelspiel).


In addition, I'm also configuring one of our more portable 
"workstations", cm-minigrail - which we used on our last Bing concert as 
the GRAIL playback unit - to use it as the main Source Streaming Server 
instead of cmn58. It's a rack-mountable unit which is smaller and 
lighter than any regular workstation we have around.


Greetings.
