x265 - Work already started?

[lucassp]

Here's something: https://bitbucket.org/multicoreware/x265/wiki/RoadMap

"Development of x265 began very recently (March 2013)" shouldn't this be March 2012 ?

There's an article on Slashdot today about the release of a pre-alpha version of x265. It includes links to evaluations by Tom's Hardware and Extreme Tech.

Interesting. Thanks for the heads up!

Thanks for the link.

Here's a build: x265 23.07.2013 (x86).zip

Your intention is good, but that URL does not work with Opera, nor with Internet Explorer 8.

Link is working fine here with latest versions of Internet Explorer, Chrome, Firefox.

Seriously, who is using outdated browsers like IE 8 in 2013, and then posting on forums to complain about it?

Thanks for the links.

I saw some articles about x265 already, today. I guess the era of rapture has begun!

There is a piece written by Tom's hardware and another one that is in czech language, so not much use unless you like google translate or something (link is here for those who understand that language.)

From the Tom's Hardware article:

We could have used the --tune psnr switch to generate higher values, though this negatively affects subjective quality compared to the settings used here.

Which means that they didn't use tunings. By one line, they forwent any real analysis and trivialized their entire article, which can now be summarized as "why yes, this is a multithreaded HEVC encoder".

I forget how bewildering rookie codec comparisons can be.

Edit: Having issues compiling this on OSX 10.9 DP. Oh well, I'm gonna try the linked binary above on a Windows rig later.

Opera is NOT an outdated browser, and I did mention it.
But thanks for your pointless reply anyway.

from the "x265 Evaluation Guide 07-23-13.pdf":

SYSTEM REQUIREMENTS
Hardware: AVX capable CPU recommended
At least 8GB of RAM
Software: Win7/8 x86_64
Microsoft Visual C++ Redistributable Update 3

assuming this is correct -> no x265 for me , since my i7 875k doesn't support AVX.

[mandarinka]

Oh, I missed that at first, but there is already an announcement in the news section of the forum.

That's a recommendation - I'm pretty sure they won't explicitly require anything higher than SSE2 (SSSE3 at worst?).

I'm not sure why you are trying to stir up trouble here, but if you continue there will be consequences. Please take any reponse to PM. Thank you.

Wow, I completely missed that x265 was being commercially funded now, no wonder it's getting up to speed so quickly. The bleeding edge looks very promising, I just hope they can integrate Avisynth soon; at least they have Y4M, so you can use an ffmpeg intermediary instead of straight raw video.

[mandarinka]

I sort of got used to avs2yuv already (10-bit filtering, testing of VP9), so as long as that is supported, I guess it is relatively fine, input-wise.

is it project from developer of x264 ??
or from the chinese guys project ??

Neither. This seems to be from MulticoreWare as discussed a few posts above. Looks like many people want to benefit from x264's fame to promote their own project.

/edit:
I stand corrected (see below).

[Dark Shikari]

MultiCoreWare's project is being made with the (very tentative) blessing of the x264 team. Unlike the others, as far as I know, it will actually be based on x264's source and algorithms and be a publicly developed open source project (e.g. something I could/might commit to). In other words, it exists as an open source project because I said "yes" to it (the alternative was a closed-source project unrelated to x264).

The intent is to link up with Videolan and friends, and there's already been quite a lot of back-room discussions, but it largely wasn't mentioned in the announcement because MCW didn't want to prematurely decide anything (they can only speak for themselves, not anyone else).

Im pretty sure it is the Chinese guys project, and Multicoreware have gotten involved and/or made some code contributions.

work here but it's really slow. Strongene_Lentoid_HEVC_Encoder work at ~1 fps on 1080p with C2D Q6600 at 2.4 Ghz.
