Atom versus Celeron

Intel Atom vs Intel Celeron: similar performance. Atom is newer and uses less power. Conclusion: Atom over Celeron.

Composite Video Capture

MythTV pvrusb2 driver with an external usb capture device.

This guy had trouble getting capture from composite to work

Use synaptic (Package Manager) to install ivtv-utils, (in some distro's its just ivtv and described as Tools) If you don't have VLC media player installed use synaptic to install that too. In a terminal type (might be a good idea to copy and paste this command)

v4l2-ctl -d /dev/video0 -i 2

and press the enter key (note 2 is Composite, 1 is S-video, 0 is TV-tuner). You will get a reply saying input is now composite.

Sample Systems for Consideration (under $500)

This one says: "WinTV-PVR-USB2 are dirt cheap, when you can find them on ebay WinTV-HVR-1950 is its replacement with digital capability "

Here are some devices:

• WinTV-USB2 - MythTV Wiki

doesn't work:

apt-get install mplayer mplayer-gui mplayer-skins

works:

install gnome-mplayer

Supports full 720x480@30FPS capture over USB 2.0. Pixel format is packed YUV 4:2:2. Linux kernels > 2.6.32 need a patched driver. The latest driver source is available from the LinuxTV project. Look for media_build. The patch is available at the Kernel Labs blog.

mplayer -fps 30 -tv driver=v4l2:normid=0:width=720:height=480:device=/dev/video0 tv://

you may need to change your input value to switch between composite(0) and svideo(1) , mplayer -fps 30 -tv driver=v4l2:normid=0:input=1:width=720:height=480:device=/dev/video0 tv://

Motion package set type to 6 'YUYV' , input 0, norm 1, and 720 width, 480 height

sudo apt-get install tvtime

I think the device or the driver defaults to PAL. When I specify NTSC the video feed begins to work properly

mplayer tv:// -tv driver=v4l2:norm=NTSC:input=0:device=/dev/video0

There is still no audio. And mplayer is the only thing using the device.
