CoreAVC 2.5 (for Windows) Released

[Copernic Reporter]

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.

CoreAVC Professional 2.5 (for Windows)

shame there is no trial, would be nice to know how it handles 4000 bitrate 720p x264 files on my sister's laptop as its jerky, 3200 bitrate is smooth on it, not worth paying $10 to test it.

Recommended Hardware Configurations for proper CoreAVC? Playback

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.

Seems good, just one minor glitch is that I cannot seek in WMP 12 with a MKV file but v2.0 works fine.

Think i will stick with CCCP

Had to move from CCCP to Shark's. But I have also tried CoreAVC. It is very very good.

Why you use WMP (WMP = the only reason for external codec pack)?

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 There's only really outdated ones around.

[bryonhowley]

Might give it a go now that they have added ATI GPU support as it was completely useless with only Nvidia Cuda.

[figgy]

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.

[dknm]

? or ATI with Microsoft's DirectX Video Acceleration (DXVA) interface

Oh look , it's 2011 and I can pay 10$ to get my video accelerated (free isn't cutting it anymore). Mindblowing !

Maybe next time they'll toy with OpenCL or smth ...

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.
