The platform is ideal for xbmc. It has HDMI, a powerful CPU and DSP (BCM2835) capable of output 1080p HD videos. Most importantly the price is only about $35 for the model B with 256MB memory.

I believe it uses OpenMax as the API for video hardware accelerated decoding.

From the available demo videos I have seen so far it looks like it does not have Xorg instead fb device is used for video rendering.

The hardware is almost identical to Ruku 2 XD.

They will probably release it in 1-2 months time. Anyone interested?

You should talk with Davilla about this Smile

I have played with the Raspberry Pi, and it is frustratingly slow (not surprising based on spec) running ubuntu/lxde
I think it would be on par of beagleboard, so dont expect high framerate without a lot of optimisations. This is all guesswork as I have not worked on getting xbmc on it yet.
The only good thing is the cost, so cheap, anyone and everyone should pick one up, if only just to play around with it!

I think the interesting part is if it has a usable dedicated video decoder and it can handle the interesting content. Because even beagle is enough to display a limited skin of xbmc in 720p with 30fps. So could be a contender (or floss version) of atv2.

But yeah, the GUI might need customization, don't buy it and expect every skin to run perfect on it.

According to ebenupton (pi employee) the GPU of Raspberry Pi is about 3 times the speed of an OMAP 4430 in common shader-heavy benchmarks. The GPU/DSP is cable of 1080p 30 fps full HD H.264 Video Encode/Decode.

The BCM2835 was designed to have a much better GPU than its competitor's product. I believe someone in the forum is already working on it. Will wait things to unfold in the next month or so.

http://openlinux.amlogic.com/download/linux/doc/

amlogic seems to have developed their own media player called amplayer2 which also uses ffmpeg. The amplayer2 can run as daemon and being controlled via socket and dbus. I believe we can at least use xbmc to launch external player (amplayer2) to utilise the hardware acceleration. The android sys image reveals that openmax api is being used (needs someone to confirm) but similar library is not present on the linux rootfs.

anybody has working RS232 on geniatech ATV2000(Amlogic 8726-M) ?

It's not RS232 on the white connector, its 3.3v TTL serial. you need to use a 3.3v serial TTL adapter.

Cheap attractive 1080p capable ARM Cortex A8 based hardware that comes with a remote? - RockerC - 2011-10-17 13:00

Do you think that you could run Linux and XBMC on-top on Rockchip RK2918 ARM Cortex A8 chipset based hardware? Confused

if XBMC can't be ported to Android yet could this box with Linux still become a cheap 1080p alternative to Apple TV 2?

To summarize, this Rockchip RK2918 SoC package contains a ARM Cortex A8 Single Core processor capable of running up to 1.2Ghz, with 3D GPU hardware graphics using Vivante GC800 that claims to do up to 57 million triangles per second and full OpenGL ES 2.0 and be fast enough to smoothly run all the latest Android 3D games.

The above "Android TV" box uses Rockchip 2918 chipset and 512MB DDR II RAM with 2GB built-in flash memory and supports USB mobile HDD up to 1TB, or SD card up to 32GB.

@RockerC, I already answered that question in another thread that you started, please don't threadjack.

I have not started any threads about Rockchip RK2918, sorry but I find no answer or reply about it?

I see that you have replied to someone else who asked about about a Realtek box that do not support OpenGL ES

Could you be confusing this with what that other guy wrote? Rockchip is not the same as Realtek

Again, I am asking about the Rockchip RK29xx chipset, a chipset with Vivante GC800 GPU that support OpenGL ES

thx
It works with 3.3 TTL adapter Smile

Lets start with port of some distribution

There is ARM support, and there is Open GL ES 2.0 support (for the most part), so in theory, yes Rockchip is a possible SoC that XBMC can run on.

If you do manage to do this, and things needed modifying, etc... we would greatly appreciate patches in order to merge into xbmc.

Thanks

Can you define "for the most part"? Do you think this RK2918 chipset could be good enough for running XBMC at 1080p smoothly?

Vivante claim that their GC800 GPU support all these APIs

Rockchip is one of those SoC producers that won't provide source code not matter how hard you try, so you better avoid it, or sooner or later you will need to modify something i.e. in the kernel and be totally stuck. That is why I prefer Amlogic, even if they won't give git access to almost anyone, they update sources on their web site every two months or so.
