OK i got dumb question. Now that the cubieboard is announced I am curious.. the raspberry pi is 700Mhz core vs the cubieboard of 1GHz, but both have the Mali-400 GP, so

1. Does this mean the cubie might be more capable in movie playbacks? Basically is the GPU's ability tied to the CPU's in SoC?

2. Does this mean we have to wait for another cubieboard port of XBMC like raspBMC?

Cubie more expensive but feature looks nice, raspberry pi I can overclock up to 900mhz and stable

Cubie looks like clone of Raspi but with faster cpu more RAM. and a few extras.
Should run raspBMC straight, but without the "extra" features.

Try the quad core ODROID-X

I saw another ARM based board on the market. http://cubieboard.org/

Specification seems much better than the current Pi.

The SATA port is really good for attaching SATA HDD for media center purpose... rclxms.gif

4GB flash on-board, no need a SD card...

Of coz, we always welcome more and more RAMs!!!!

stream from your pc? external harddrive? wifi or ethernet?


I play mine via class6 sandisk 32gb SD card. Smooth smile.gif

- it takes some time to copy over via putty psftp.

try this thread on raspbmc.

http://forum.stmlabs.com/showthread.php?tid=1269

Does it lag if you copy the file over to the SD card?

I seen some people saying to run xbmc properly they up the swap file on the SD card. Forgot where I saw it though. sad.gif I tried looking but yet to find it.



This thread probably has more stuff that relates to your problem.

I got around to do some testing with raspbmc + transmission. I have it connected to sony tv40BX420 - donnu got DTS or not, but seems like it works, got an old Pioneer Dolby Surround sound amp that was was working for a Lazer disc player. The sound pass thru to the amp no problem, tv also got sound at the same time.(reason i mention this is because, other people on raspbmc forum has reported that if your tv/receiver cannot decode DTS, forcing raspberry pi to cpu decode will cause lag in 1080p)

*** also try to change the refresh rate of your video to match your video files framerate, could work.

After muddling around with it twice. Since I made the noob mistake of running apt-get update & upgrade manually.

Anyhow 2nd time also mess up the first ssh in config...

I dled a test file Gangnan style from youtube. 178mb
SQL
Stream 0
Type:Video
Codec:H264 - MPEG-4 AVC (part 10) (avc1)
Resolution:1920X1080
Frame rate:23.976023
Decoded format:Planar 4:2:0 YUV
Stream1
Type:Audio
Codec:MPEG AAC Audio (mp4a)
Channels:Stereo
Sample rate:44100Hz


using psftp to put it onto Raspberry pi.



My refined raspbmc + transmission installation. Note: I have yet to set up smb or nfs or an external harddrive. Running purely on 32gb SD card. I have a seagate 250gb external slim hdd, which i doubt will work since it draws entirely via usb connection.

I set my transmission to 40 peers, download limit of 50-80, up of 5-9, since i using lousy streamyx connection only... sad.gif I was able to play the 1080p file and sustain 80KB/s download, 8up.

I used information from this page and modified a bit to my purpose

CODE


sudo initctl start xbmc    <start xbmc from putty>
sudo initctl stop xbmc   <stop xbmc from putty>

Using Pi user
sudo apt-get install transmission-daemon

sudo /etc/init.d/transmission-daemon stop
Using the pi user
sudo nano /etc/transmission-daemon/settings.json

<whitelist-192.168.1.*, download-\/home\/pi\/downup, password, username-root>

<only on NTFS>

sudo chmod g+rw /home/pi/downup
sudo chmod g+rw /home/pi/transfer
sudo chmod g+rw /home/pi/anime
sudo chmod g+rw /home/pi/movie
sudo chmod g+rw /home/pi/music
sudo chmod g+rw /home/pi/musicv

sudo chgrp -R debian-transmission /home/pi/downup
sudo chgrp -R debian-transmission /home/pi/transfer
sudo chgrp -R debian-transmission /home/pi/anime
sudo chgrp -R debian-transmission /home/pi/movie
sudo chgrp -R debian-transmission /home/pi/music
sudo chgrp -R debian-transmission /home/pi/musicv

net.core.rmem_max = 4194304
net.core.wmem_max = 1048576

sudo /etc/init.d/transmission-daemon start





I created extra folders, but not sure if it could be properly used by transmission. The last install of xbmc that i did with raspbian, the entire 32gb got filled and i end up wiping the whole sd card since, it refused to delete stuff in rubbish can. So it could be a chmod problem.


**** the raspbmc - totally got my sony tv remote's cec to work on it. Fast forward works, backwards doesnt. Stop, play, next all works. Yippee free remote!

How do you get your Pi to utilize the 32GB? Use Gparted? And what is the idle CPU usage? Mine always 100% even idle. Guess I need to fine tune some setting.

And CEC not work with my Panasonic TV. cry.gif

Hmm, raspbmc installation, took care of partitioning. So I did not have to do any additional partitioning. (previous debian had to do the partition expanasion to fill entire 32gb, since the raspbian started, the first time boot, they got like a config program to run and do that job smile.gif



Initially was at 100%, after 10minute or so is at 75%


CEC, did you go into the setting and see if your is enabled? go to system, setting/system or something like that. special one on input.


I cant figure out why though, just one morning of dling some jdrama and it seems to have taken up 10gb of space when I just dled actually 2gb of stuff. weird.

When connected to my Samsung TV it detects CEC compatible device and auto enabled CEC (the prompt appears for a few seconds on the lower right of the home screen). The basic remote buttons (up,down,left,right,enter) works as expected, but other buttons gave unpredictable results.

No CEC prompt appears when connected to my older model Sharp TV.
