I have a number of video pieces I am looking to loop in a gallery. I will
need to install 25 different screens (that will be sold in an edition of 5)
that will loop different videos. This means I will potentially be ordering
125 different video kits.
I am looking for the most cost effective way solution and I believe a
Raspberry Pi with this player should suffice:
http://www.adafruit.com/products/1287
A few questions:
-does this screen contain any internal RAM so i could play directly through
the screen and not get the Raspberry Pi?
-would i need some sort of adaptor to hook the raspberry pi to the screen
(ie. HDMI etc)
-Do you have other 7" or 10" screens that have RAM that could work as well?
-do you sell any video 'kits'?
-would the raspberry pi and this screen be able to run on a 9v battery if I
purchase the 9v battery clip?
-does anyone have other ideas/solutions? I will also need to create frames for each piece to ensure they display properly in a gallery setting.
Thanks for any and all help!

Re: video looping
A couple of questions. How big are the videos and what frame rate are you expecting? Do you needs sound? As to your question on the 9 volt battery, it would not work for long, if at all.

Re: video looping
Hi Franklin,
The videos are around 1.5mb each but I could reduce the size if necessary. I would not need sound. But I would need these to loop for hours/days at a time without a problem.

Re: video looping
Did you ever figure out how to do this? I'm working on something similar.

Re: video looping
In direct answer to the questions above:
[/quote]-would i need some sort of adaptor to hook the raspberry pi to the screen (ie. HDMI etc)[/quote]
The RasPi generates an HDMI signal, so all you need is an HDMI cable.
9v batteries can't deliver that much current, and only hold about 600mAh of energy under the best operating conditions. Drawing current at RasPi rates would drain the battery in about half an hour.
If you want to run a RasPi from a battery, you'll need a pack that can deliver 5v @ 1A like one of these:

https://www.adafruit.com/products/1565 - 4400mAh
https://www.adafruit.com/products/1566 - 10,000mAh
or a straight LiPo cell and a boost converter like one of these:

No display I know of does that.-does this screen contain any internal RAM so i could play directly through the screen and not get the Raspberry Pi?

As above, I don't know of any display that will store video.-Do you have other 7" or 10" screens that have RAM that could work as well?
Not as such. Just the parts.jcalcote wrote:-do you sell any video 'kits'?
No. A RasPi needs at least 350mA when it's running idle, and tasks that put a lot of load on the CPU (like decoding video) will take the current consumption up to about 700mA.-would the raspberry pi and this screen be able to run on a 9v battery if I purchase the 9v battery clip?
