CoreCodec CoreAVC 2.5 for Windows is a complete solution for playing high quality HD H.264 videos on your Windows based computer. CoreAVC comes (in part) from the creators of the Matroska MKV Container (.mkv), So you know it's gotta be good! CoreAVC fully supports GPU hardware acceleration with NVIDIA CUDA Technology, and works with other compatible NVIDIA Platforms like ION running on Windows XP, Vista, or 7. If you have a slow computer that is having problems with H.264 playback, you can try using it.

CoreAVC is known in the industry as being the standard for playback of high quality H.264 video. The new CoreAVC Decoder allows you to offload video decoding to any accelerated decoder that works with either NVIDIA CUDA or ATI with Microsoft's DirectX Video Acceleration (DXVA) interface for any Windows XP, Vista, or Windows 7 PC.

The CoreAVC? H.264 Video decoder for windows directshow has the following 'recommended' hardware configurations below: Noting that the recommendations listed are measured for full screen video playback and a more powerful system will deliver the best playback experience. But because of how efficient CoreAVC is, you may find that what it takes to perform at these levels can be achieved just as well on a slower PC too.

DivX Plus HD was the fastest h.264 decoder and adds mkv support for windows media player.

Plus its free! (install DivX Plus Codec Pack)

I think Divx still wears the performance h.264 performance crown.

So there is very little reason to use corecodec as far i am concerned.

That's why I'm curious about performance, DivX being free (and quite good) makes CoreAVC a hard sale.

I wish someone would make a comparison between this and the lastest DivX plus. There's only really outdated ones around.

Interesting, thanks. So wait, it's faster to use the cpu? or am I missing something?

Better be trolling,

- DivX is really slow compared to CoreAVC.

- DivX is buggy compared to CoreAVC.

- Everything adds MKV support for WMP.

- I would avoid WMP and use MPC:HC for empirically higher quality and more performance friendly Haali Renderer as well as more performance friendly subtitles.

maybe i am mistaken, but what's the point of this software?

free video players like PotPlayer already supports hardware accelerated h264 video playback on my Radeon 5670 fine through dxva.

CPU use with dxva on is around 5percent on my AMD Athlon 3600+ dual core (2.0ghz overclocked to 2.4ghz). 720p/1080p x264 (h264). without it... 1080p gets out of sync and 720p plays fine but CPU use is 30-40percent area.

Not all renderers support DXVA.

If you want a quality presentation, you will use MadVR which doesn't support DXVA.

With CoreAVC, you can use CUDA with MadVR for fast and great quality video.

Well a standard x264 720p (7GB) file seems to be a negligible difference in image quality with a big CPU hit when using MadVR. (since DXVA is disabled)

i.e. it's not worth losing DXVA for the slight (to negligible) image quality increase.

note: i tested it on PotPlayer with madVR enabled and then it's default mode which uses dxva. (and like i say i can notice it did change the image some but it seemed to mostly introduce jaggies in the image where as standard dxva is more smoother.

    • Macbook Air is an appealing option, as are plethora of Windows devices with various different CPU's
    • Mozilla highlights Firefox Nova 2026 redesign and more upcoming features with new roadmap by Sayan Sen Last month Mozilla confirmed that Firefox was set to get a major redesign this year. Dubbed "Project Nova", it can already be tested and will roll out to all users later this year.The idea is to keep the browser competitive in a rapidly evolving internet landscape. As such the revamp focuses on improving privacy, usability, performance, accessibility, and customization. Key privacy features including the built-in VPN, private browsing mode, and Enhanced Tracking Protection, will be more visible and easier to manage, while users will have the option to disable AI features entirely through a dedicated kill switch. Additionally, the redesign promises faster page loading, the return of Compact mode, expanded personalization options, and stronger accessibility support. You can find the full details in the dedicated piece linked above. In a new blog post today the company once again reiterated on Nova and also emphasized other new and upcoming features like the settings revamp that is intended to make it easier for users to understand browser settings. In order to make it simpler for users to keep up with such features Mozilla today is launching Firefox roadmap. Hence enthusiasts and interested users will be able to check out what's cooking and also share feedback about the upcoming additions. Alongside the roadmap announcement, Mozilla also highlighted what's new in Firefox 152. One of the biggest additions is the arrival of Tab Groups on Android. The feature, which has already been helping desktop users organize large numbers of tabs, is now beginning to roll out on mobile. Users will be able to group related tabs together, assign names and colors to them, and return to them later. Mozilla says support for iOS will arrive later this year. Firefox 152 also introduces the aforementioned redesigned Settings experience. The company says the changes are meant to make controls easier to find and help users discover features they may not have previously known about. Existing preferences are not changing, though they are now better organized. Another notable addition is the new Blocked Tracker Widget, which provides a visual overview of Firefox's privacy protections by showing how many trackers have been blocked over time and the types of tracking activity the browser has stopped. Looking ahead, Mozilla revealed several upcoming roadmap features. They include customizable keyboard shortcuts, as well as enhanced PDF editing tools that will allow documents to be split, merged, and reorganized directly within Firefox. The company is also working on bringing Multi-Account Containers into the native Firefox experience thus removing the need for a separate extension. Meanwhile Firefox's built-in VPN is set to expand to mobile devices. Mozilla is also developing AI-powered features like Quick Answers, which can provide concise responses to voice queries, and Smart Window, its optional AI browsing experience that is now available without a waitlist. Finally, a new Power Saving Mode is in the works and will help reduce the impact of resource-heavy tabs on mobile devices in order to extend battery life. The video below summarizes the upcoming changes in an easy to understand format: You can find the announcement blog post here on Mozilla's official website.
    • Dead on arrival at that price. Like they missed the mark by multiple hundreds of dollars - this should actually undercut the Macbook Air at $899 if they want any sort of sales / further adoption of WoA
    • Wow, 50% increase for the base model. That's steep!
    • A group made up of dozens of cybersecurity experts, including several well-known veterans of the industry, published an open letter to the U.S. government asking it to lift the export control order on Anthropic’s Fable and Mythos models. According to the open letter, “this action has taken the best models away from [cybersecurity] defenders” who now can’t use the models to find vulnerabilities and make their software and products more secure. “To pull the best capabilities away from defenders without a good reason when our adversaries are rapidly advancing is dangerous,” read the letter. On Friday, the U.S. government ordered Anthropic to limit the export of Fable and Mythos, citing national security concerns, without explaining the specific reasons behind the order, according to Anthropic. In response, the company suspended access to the models to all users worldwide.     https://techcrunch.com/2026/06/15/cybersecurity-vets-protest-dangerous-us-government-ban-on-anthropics-most-powerful-models/
