Yes the Pi's graphics chip can decode h264 in hardware in realtime... It can also encode h264 in realtime to, that functionality comes free with the Pi


Dude, ur exploding my mind. :)

Does Ouya have all the same magic that Rpi has, just more?

Can I assume that a Ouya would play movies even better than Rpi?


But just because Pi can do something in hardware does not necessarily mean it can play every single movie at 1920x1080 @60fps.  Some movies are much harder to play than others, especially scenes with a lot of small moving objects everywhere while the camera is rotating.  That is phenomenally hard to play correctly.

My bro has this pc with a 2Ghz core2duo and some kind of gfx card and it has severe problems playing 1920x1080 movies.  It can sometimes play them ok but usually the framerate jumps up and down wildly during the movie even when 2 ppl are just sitting there talking to each other.

I need to ask you a question: Do u (or did u) play a lot of FPS games on your home computer?
Wanna try a wonderfull strategy game with lots of handdrawn anims,
Magic Spells and Monsters, Incredible playability and lastability,
English speech, etc. Total Chaos AGA

The Pi has no problem with HD video at all, the Chip was designed for video playback... The CPU core was originally just for housekeeping functions... But the RaspberryPi team use it for running an OS :)

I use this on my Pi and the UI is very responsive.

I have the 512MB model running at 1GHz.


Does that distro support 4TB NTFS drives on the Raspberry Pi?
Read only?
Or Read/Write?

And if not, then what filesystems do ppl use on Rpi that support >4GB files?

It sounds like the same philosophy as the A1000!

Is Ouya running Jelly Bean?

Both 4.1 and 4.2 are Jelly Bean.

I'm using exfs4 (SD cards), and HFS+ (external drives) on my Pi... But it is running Linux, so pretty much any file system will work.

Yeah, actually it does :)

To expand on what I said earlier, the Raspi was designed to be a graphics chip for mobile devices, with a small ARM core to basic housekeeping work. The device actually boots the graphics chip first (as with most modern graphics chips it is a fully programmable processor in it's own right, and has it's own OS and kernel that is on the boot SD card), and then it brings the the ARM core online and sets up the operating system ready to boot. Once the ARM core is active, the ARM runs the operating system and that takes over control of the board.

The down side to this architecture is that the ARM is nothing very special (not super fast but does have some advanced features like an FPU and a Vector unit) and must share its RAM with the graphics core.

There are some rather nice DSP cores on the chip too, but Broadcom haven't given the Raspi team permission activate them in the firmware (yet!).

Yep if you just want something to emulate an Amiga either get an OUYA, FPGA Arcade or a good old MiniMiggy

I'm still in two minds about emulation of retro platforms, I guess it's pretty cool but it's still not the same as having the real HW.   I've got a feeling that if I brought something like an OUYA for retro gaming that I end up spending most of my time playing newer games on it :)

I historically buy Amigas, and play with them for a while, but later can't
justify having it around, and sell it.
Sooner, or later though, all of the genuine custom chips have got to fail,
and that's that, so we kind of do have to look at emulation at some stage.

A real A500 is tempting, but the extra hardware for LCD monitors,
and real floppy load times.. I'd prefer to cheat this time ;)

Raspberry Pi also sounds like a good platform for a GPS program.
