How to tell if video card supports H.264 hardware acceleration?

Hi All,



Is there a way in Windows to determine whether or not your video card has hardware H.264 acceleration or not?|||Download an H.264 file from somewhere and see if it runs ok. H264 is purely a video codec, nothing else. Its designed to allow the playback of HD movies and such. VLCplayer comes to you completely free and it supports this format.



What would be helpful is the make/model number of your video card and that will tell me if its capable or not.



Hope this helps :)|||Sorry its taken so long to get back to you mate. To answer your question the H.264 codec plays video files at high resolution. That is the only factor you need to consider. As long as the video card can display a resolution as high as the HD video then in theory it should play without issue.

For example:

ATI HD 4600 Series GPU Specifications:

2nd generation Unified Video Decoder (UVD 2)
