Hi,

I'm just wondering what would be involved in getting divx videos to decode on a board such as this (http://www.embeddedarm.com/epc/ts7250-spec-h.html) one and streaming the video out through a tcp socket. Is it a simple case of grabbing a decoder and chucking it on the internal memory? or would it involve weeks of porting and/or hacking to get it to decode.

I know next to nothing about this topic, so any advice/reading links are welcome.

EDIT: Actually, the think i'm most interested in finding out is if a 200Mhz arm processor is physically fast enough to decode video.

Well it depends of the target resolution...

The Atmel at32ap7000 of this board (http://www.atmel.com/dyn/products/tools_card.asp?tool_id=4102) (which is cheaper btw ;)) claim to be able to decode QVGA Mpeg4-SP at 150 Mhz (but i suppose you need to use the co-processor/DSP for that, so no straight compilation).

To gave you a rough idea, 200 MIPS is something like a Pentium 233 :D
