Austria microsystems have a new range of ARM9 based mcus for audio and video...I was looking at using one to produce an I2S stream for a high end dac feeder.

Hi
Cortex M3 & M4 don't have the power to run H264 decoder - to week for the task
You will need cortex A8 or other strong processor to run H264 decoder

All the best

The video codec is not very important any other video format is good.
I just want some video displayed on the colorful lcd.

Hi

Take the stm32F2xx or F4xx this new device have camera interface - so all you need is to connect a camera chip And an LCD
to display picture - you can buy the the ST evaluation  board and download a demo code from ST site

All the Best

I have used the STM32F2xx and 4xx. It is easy to connect to an LCD interface. For decoding video you need a lot of CPU cycles, and preferably a dedicated hardware block decoder. Something simple like motion-jpeg with low resolution is probably possible. The demos I've seen simply display a series of BMP (bitmap) files.
