View Full Version : Minimum specs for 720P playback?

24-07-2011, 11:06 PM
I just went and bought an HP DM1 Netbook. Whether I hook it up to my HDTV via HDMI or just try to use the netbook screen itself to watch a 720P vid using VLC, the image stutters, freezes and pixellates. Are there features that need to be turned on or is my netbook just not up to the task?

Here's the hardware specs,

1.6Ghz AMD Dual Core Processor E-350 , 1MB L2 Cache)
4GB DDR3 Ram
500GB Hard drive (I swapped this out with an Intel 40GB SSD).
AMD RadeonHD 6310M Discrete-Class Graphics
Microsoft Windows 7 Home Premium 6Ghz, 1MV L2 Cache)
11.6" Diagonal High Definition HP LED Br

Specifications (I'm quite sure what they mean by 'stunning'and 'powerful' if it can't handle HD)

1.6Ghz AMD Dual-Core Processor E-350 Cs has stunning entertainment features and powerful performance all in a stylish and highly mobile 11.6" widescreen chassis.
4GB 1066MHz DDR3 (1 Dimm)Ram
500GB Hard drive
11.6" Diagonal High Definition HP LED Br
Webcam with Integrated Digital Microphon
Microsoft Windows 7 Home Premium
Integrated 10/100/1000 Gigabit Ethernet LAN (RJ-45 connector); 802.11bWLAN + Bluetooth®

A few sites say 2.4 Ghz +. Dont know if that means single or dual core. Probably dual core

I find VLC not so good anymore, ie making more demands on computer, my Pentium III laptop can show DVD's or avi's directly to a TV which it does quite well, and it is on XP and 1Ghz with 375MB ram, *shame*.

Try this version of MPC home cinema:


it's just been cleaned up and is working like it used to again.

Marketing hype, of course!

I think you will need to do this: http://wiki.videolan.org/VLC_GPU_Decoding

it's possible the graphics isn't powerful enough to accelerate video playback or .vlc isn't using it.that cpu is too slow to do it alone. on the other hand even an atom based pc can do 1080p with sufficient graphics acceleration .

That new Amd APU can play 1080p no problem.
As suggested it sounds like the CPU is doing the decoding rather than the GPU.

I've done 720p h.264 decoding from a single-core 1.6Ghz Atom without *any* GPU acceleration.

The CoreAVC codec helps a lot, it's worth forking a couple of bucks for it, and use it with MPC-HC.

m parents have an HP DM1Z notebook, probably the same as yours? It plays back 720 content fine. It also depends on the bitrate.

You shouldn't need to use CoreAVC, the Radeon should have hardware decoding. Depending on which VLC version you are using, it might not support hardware acceleration.
