Issue playing H.264 files on laptop

Duradrum · 7 Feb 2007 at 16:28

Hiya,

I have a laptop with the following specs:

Core 2 Duo 2.0ghz
2gb ram
Ati X1400 Mobility

I used to be able to play H.264 files fine when using XP Pro but since upgrading to Vista Home Premium I have the problems below.

I'm having problems playing Hi Def H.264 files on it. I have installed CoreAVC and a couple of other codecs but the video is still 'choppy'. I thought the specs of the laptop would be ok to play these files.

Any suggestions?

Thanks in advance

What program are you using? If you haven't tried it already VLC Player is good.

An x1400 wont have h.264 decoding like desktop cards do. So the pc might not be powerful enough to play 1080p videos.

Try vlc.

X1400 cards do have H.264 decoding, it worked fine in XP!

VLC player just gives me a white screen with audio. Media Player works but with the above problem

Is it Media Player Classic by any chance and is the H.264 file an MKV?

WMP11. The file is a .ts file.

Hmm have you got ffdshow or nero showtime?

Another possibility (and i'm only guessing) is that the Vista driver for your gfx card doesnt yet include any of the hardware decode assist that the XP driver offered and that could be why its now choppy as hell.

try WMP Classic with ffdshow as a clean way of decoding H.264.

As an aside, where are you getting H.264 in MP2 transport streams from?
