Hi, thanks for the update, but I get update notifications about both of these pieces of software now and I’ve already installed them both. (Just got the new drivers a couple hours ago.)

Blog post about my new software notification system coming soon-ish (within the next month or so).

I had that enabled already, actually…
If the bitrate is high enough (like that of a Blu-ray disc), 1080p content still does not play smoothly with libavcodec/ffdshow/CCCP. (Same story on Windows and Linux.)

This is just on my laptop (which is my main personal machine), which has an Intel Core 2 Duo as I mentioned before. I tried it on a dual quad-core Xeon machine and it worked fine.

I’ve been meaning to make a follow-up post to this since a few things have happened, but I haven’t gotten to it yet, so I’ll briefly summarize here:

* I’ve gotten DXVA to play back the high-bitrate h.264 at full speed. However, I have a few videos (not from Blu-ray) that DXVA seems to disagree with.
* CoreAVC 2.0 is out, and while they fixed my decoding error, I find that it requires more CPU than 1.9.5, so videos don’t play smoothly anymore. A quick look at their forums reveals that I’m not the only one this happened to.

“However, I find that libavcodec is not fast enough to decode high-bitrate h.264 content in real-time on my machine (2.4 GHz Core 2 Duo)”

Not really. That’s because by default only single-threaded decoding is enabled in CCCP. Your machine is perfectly capable of decoding 1080p content; you just need to enable multithreaded decoding under CCCP Settings (check the “MT” box next to the H.264 box). No need to futz around with alternatives.

I haven’t had any such trouble with Windows 7. I am assuming that you are using a full-screen (4:3) monitor. In this case, make sure the screen resolution you have chosen for your desktop display is also 4:3. Other than that, I don’t know what would cause this problem in every media app you try.

I have another question..

another question…if you can answer. before when I had vista all the videos I downloaded all played widescreen. Now with windows 7, its not widescreen anymore. Even when I put the raito to be 16:9 it wont go widescreen.
I use media player classic, or VLC. if you know how to put the widescreen back, please let me know.
