That's great to know; I didn't know this was the case.

In that light, I think we should take the plunge and go with voctomix.
We'll have a full week to experiment with getting it to work properly;
that should be plenty.

voctomix was used in the main room at LCA and had a number of issues with the setup we were trying to use. I *think* most of these have been sorted, but I would make sure you had a backup plan for if voctomix doesn't work with your set up.

State of Vocto this minute:

1. CCC uses one single desktop with blackmagic sdi capture cards.  This is the only setup that has been used without problems.

2. lca - a week before the event we tested running clients on a remote machine over tcp, discovered problems, which were likely fixed, but we never had time to properly test, so we fell back to DVswitch and only used Vocto a few times under close supervision and I think a blackmagic hdmi capture was part of that.  For sure more problems were discovered during these runs, and more patches (this time by core gstreamer devs, to a gstreamer plugin)

3. I am running Vocto here in my livingroom right now /me points at desktop:
Intel(R) Core(TM) i3-2120 CPU @ 3.30GHz

This email editing is happening both on my laptop screen and the Vocto GUI.

Once I hit send I will go back to testing the GSOC vga addon board to the Atlys (not Opsis)

I am focusing on 720p, so less cpu demands than CCC's 1080p.

I am cleaning up and organizing things so that in the next week or so I can do more testing and not be tripping over all the random hacks.

For instance, I hope this to be the defacto source client, so if someone can skim the code and comment, or even better use it (it has --test that does not require hardware)

I plan on using Vocto to record PS1 Lightning talks April 12 and maybe ChiPy talks April 14.

I plan on using 2 cameras: old SD DV over firewire and new HD over hdmi -> Opsis -> usb -> ingest.py-> Vocto.

April 12 is a hard deadline.  I'll report results April 13.
