I have ordered the starter pack to introduce myself to it and teach myself how to use it, but I have a project in mind which involves laying text over HD video in various formats (1080p and 720p for starters).Would there be one Arduino over another that would be better at handling the video?
this may do the job
Maybe one of hardware type would like to upgrade the idea for HD?
Try the Arduino called "Raspberry Pi" (Just kidding. Not an Arduino, of course.)But RPi does have the hardware grunt to do what you want (fast cpu, 512MB of ram, dedicated gpu), and are inexpensive.
While the R-pi is clocked at 700 Mhz, but my impression is even at 700 Mhz, it would struggle to read a full 1080p stream in real-time.
I see somebody asked a similar question two weeks ago in the r-pi forums, and didn't get much of an answer: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=30&t=23231
Well, given the high-level Broadcom gpu drivers have been made open source for just over a month now,
Well, _my_ Pi is clocked at 840MHz smiley-razz
But it is not the high level drivers that this needs it is the low level drivers, they are still a secret.
