Drew,
Thanks, I'll take a look at it and see what I can make work.
I've been doing content prep for the Port Townsend Film Festival and a
couple years ago we converted to Digital Cinema Package (DCP) for the
whole festival. It's kind of a disk hog because all the video is frame
by frame in JPEG2000. The upside is that it's a standard that already
exists for playout in theaters driven by xml.
One hour of 1080p video will have a max file size of about 113 GB. A
weeks worth of video (if you didn't repeat anything) would be about 20
TB. A month is about 90 TB. A 12 drive RAID6 array for a month's content
would be about $3,300 for the disks and another ~$500 for a used SAN box?
In DCP every video is a file that has a several constituent files that
contain the video and audio and all the metadata. In a theater, these
DCP directories are strung together on an xml "play list" that also does
things like open and close curtains and change the house light settings.
I personally do mostly 60 min. shows on Rivendell and it seems like it
takes forever to ingest a show (~1/4 real time). I suspect that most of
that has to do with the amount of CPU time it takes to normalize 60
minutes of audio, but a normalization certainly happens a lot faster in
Audacity. It might be that the bottleneck is reading and writing to the
NAS that has /var/snd on it over a 1Gbe network. Who knows... When I'm
building DCP sets it takes about 3/4 real time to process a video with a
64 core (4 - 8 core Xeon processors, 2 Hyperthreads per core) and an 8
drive RAID 0 SSD array and 128 GB memory. An entirely different scale of
thing. The idea of ingesting videos makes me shudder a little. :)

Bill, (Jay)

I suggest setting up a small test system to see how it all works with
video.
I am happy to answer questions and help get you going. (Perhaps if
someone takes me up on this, we can improve the documentation.)
For a video only system, all playable carts would be in rdlibrary as
macro cards with a special format.
rdlogmanager would be used in a fairly normal way to create events,
clocks, and the grid and to create the day's log.
rdairplay would be used to load the log and play it.
rdairplay and friends would instruct an outside video player to play
the correct videos at the correct times.
(Mike, perhaps you could help a bit if we made some improvements when
setting you up that did not make it into the docs / examples.)
all the best,
drew

Drew,
I sure would be interested in hearing more. What are your
adaptation's limitations? Things you think a "real" video video
automation system should do that your system doesn't achieve? What
is the hardware configuration?
Thanks,

Bill,
if what I have is good enough to fit your needs, I have rivendell
"adapted" to do video and will be happy to help you get it set up
and going.

Probably not, but is there something like Rivendell to
automate play out of video content? The city has asked us
about taking over the Cable Access channel. I know the
automation system they have now plays Sony video carts. It
sounds like they don't have money to spend to update system
and I don't want to takeover a mechanical nightmare. A nice
big RAID array of videos would work nicely but it needs some
scheduler, like Rivendell has.
