Cheapest VGA Out - hardware question

Hi Guys,

i want to feed an** output device** with information (jpegs, or movies). Therefore i would like to know what kind of possibilities i have.

The most simple solution would be, that the output manager is a computer, but it should be something much simple, which only can read and send data.

[router] =====> [output manager] ====> [OUTPUT DEVICE]

Would be cool if you could share your knowledge with me

Thank you

It’s not clear to me from your waay to generic description what you want to accomplish, but if you want to input files, do some arbitrary calculations with/on them, and output a VGA video signal, a computer is still your best (and cheapest) bet.
If what you want to do is more aligned with “normal” video/tv usage, then maybe a video mixer or processor would also do, but this will be less flexible, and way more expensive, at least at VGA resolution you seem to require.

It’s for feeding a “screen” from outside via Internet.

Are there any preferable computers, which have small size?

thank you.

There are media players that can be updated via the internet. Or something like a ‘smart tv’ that can be pointed at a webserver?

Otherwise a small headless computer? Google ‘mini itx’

maybe something like http://www.amazon.co.uk/Aopen-Digital-Engine-DE7000-91-ADE01-7010/dp/B003KCLW66
“digital signage” is what you look for I’d think.

If you can use HDMI rather t6han VGA then this is pretty cheap (although not actually buyable yet)

but would actually OF run on the Raspberry Pi ?? That would be really interesting. I read in their FAQ that it will support Debian. anyone knows?

If it runs debian there’s no reason why it wouldn’t.

Whether it runs well now… There’s another question.

I believe it’s a 700 MHz arm with 256mb ram and some kind of integrated graphics.

in my case, we are trying to get multiple displays with HD video output of different video files. For this we are using several computers running an app developed with OF that receives OSC instructions to start-stop de video. Currently we are testing with four different machines (three laptops and one desktop). Because there are all different hardware they react differently to loading the video. All the videos should be in sync as much as possible so we are currently using delays to compensate. Being able to use something like this would be great because all machines would be identical and it is cheaper than buying 4 identical laptops. I guess it would be a matter of buying one and running some tests

The system on a chip in the raspberry pi is designed to play back 1080p and supports OpenGL ES:

If you look at this discussion
http://www.raspberrypi.org/forum/features-and-requests/bcm2835-datasheet/page-8

It seems that some specific drivers are needed before the GPU will be accessible from linux (and OF)… considering the amount of interest the raspberry pi is gathering it seems likely that somebody will write this.

I see. thanks for the answers
