Re: x264 and Intel 4500MHD
Yah, I've about given up.. I'm lost likely going to get a new laptop w/ dedicated video.. some of my 1080p's still pause.. but I will certainly given windows7 a try to see if it's better.. |

Just FYI, but unless they've changed the drivers between build 7100 (the release candidate) and the RTM build, I had a ton of trouble with this card and Windows 7. So much so that I went back to Vista on my HTPC. Intel has officially released Windows 7 drivers that I haven't tried (I'm waiting on native Netflix integration like Vista has), but just a warning that it may not be the holy grail fix. I do think it's worth a shot though. |

I got it working with a pure codec pack with cyberlink (DXVA) as the H.264 decoder & windows media player as the player. I had to manually associate windows media player with .MTS files (1080p) H2.644 files I had. I have windows vita 64 but used the 32 bit codec pack & 32 bit windows media player. I can watch the v1080p video on intel 4500MHD (GM45) with just 25% cpu util now & no pauses & perfect lip synch!!!! Hope this will help all the other intel 4500 MHD owners. |

said by Matt :Although I didn't have Quicktime installed, I just installed and tested it with Transformers Revenge of the Fallen 1080p and my CPU bounced between 25% and 40%, mainly in the low 30% area, while playing it full screen. It was perfectly smooth. WOW the blu-ray is out while it's still in the theaters? |

update anyone? I'm about to upgrade to an Acer Timeline 4810 with extremely skimpy cpu (Intel ULV 1.3Ghz SU2700) but with Intel GMA 4500MHD. 1080p is def. a bonus, but I wanted to make sure I could get 720p x264 in matroska container playback with DXVA utilizing the Cyberlink h.264 codec in Vista Premium? If it works, even with the skimpy processor I'm anticipating under 25% cpu utilization during playback, based off what I've read. Can anyone concur? |

Jamestown, NC | I have since read that the 4500MHD and the X4500HD are two completely different chips, with the 4500MHD being terribly underpowered. That could be why I didn't have problems but the OP did. |

720p is easy on the 4500mhd.. If I had to guess 25% or less would be right.. 1080p without jutters or lag is a maybe.. I would not expect miracles.. I have a 15 Gb MKV of "the princess bride" that I throw at anything I want to test.. and more than likely even with windows 7 now on my lappy it would still fail..
I upgrade recently my desktop to a phenom II x4 50 and I was shocked to see my cpu with the above movie is like 2% (course I was running vista x64 at the time) now that I'm running windows 7 x64.. it's 33%? Well.. weird.. (too bad I didn't take a screenshot.. I'm guessing windows 7 not optimized properly  ) |

I'm happy to report that the 4500mhd now successfully tackles just about anything..
My system is still the same but now with the new
K-Lite Codec pack 5_40
I am seeing 20-40% CPU usage across the board for any x264 the thing in that codec pack that seems to make it work is something new called "DXVA" sometype of hardware based encoding for GPU is my understanding.. I tested even my toughest file princess bride and it didn't break a sweat past 40% cpu.. really 20% is average on my dual core 2.0 ghz
In my new testing with my laptop the only thing I found causing me some headaches 80% cpu + where some .mts files from blueray rip's.. and some actually worked in "DXVA" and ran at a base of 20-40% |

Whether using CoreAVC or FFDShow, or whatever decoder, there should be an option under h264 (or AVC) settings where you can change the deblocking levels.
Try "skip deblocking when safe" and see if that makes any difference. You can also try "always skip deblocking", which will yield a slightly lower quality image, but should improve the framerate and lessen the likelihood of audio sync issues.
There should also be an option to "drop frames" to prevent audio sync issues. |

| DXVA does make a huge difference if your GPU supports it. DXVA is GPU offloading for decoding which most stream based GPU devices are much, much more efficient at than x86 processors are.

Yah, it seems to work well but there are occasional glitches.. dunno if that's the codec or the 4500mhd  I'd say a glitch can appear every 10 minutes or so.. or sometimes not.. |

good stuff! happy you finally got it working..
i read this entire thread and noticed that not a single person asked if you had tried using any different software to play the files/discs.
As you found out, you need playback software that WILL take advantage of the gpu decoding features...mediaplayer and quicktime DO NOT.
i suggest powerdvd....but you apparently found something that works as well...or a codec that allows acceleration under mediaplayer...
although i still suggest using powerdvd |
