Drew,
I have tried a bunch of DCP tools and right now my fav is DCP-O-Matic
<https://dcpomatic.com/>. Free, Linux and does a good consistent job. It
really knows how to keep the CPU cores hum'in too . It supports cluster
rendering of the JPEG2000 frames and in fact, I have 2 of those 32 core
machines (Dell R720's) in my set up at the Film Festival that have a 10
Gbe network that connects the cluster. There is a DCP-O-Matic player but
I haven't really used it for much and only have a cheap PCIe video card
to playout through. I suppose people have used this in small theaters
but I really haven't gone there because all the theaters the Festival
use are using Dolby/Doreme projectors that use DCP natively.
I'm not sure about VLC. I don't think it knows about DCP yet. It can
probably play the constituent parts but I don't think it can play them
all together.
I've got to run out for a while but I may come back a check into IRC.
I'm Navion in there.

Bill,
if you want to come to #rivendell in irc at freenode, look for zotz.
If you would like to voice chat in a google hangout or via phone, let
me know and we can work out details.
Do you know of a good dcp video (with audio) player for linux?
I did some dcp work years ago in making a commercial for the station
to run on local theatre screens, but I don't recall if I had a player
or not available at the time. Can VLC do it yet, I just saw something
saying it could not yet do audio and video at the same time.
all the best,
drew

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.
