CoreCodec/H.264 Codec "CoreAVC"

[ACrowley]

"So far i can" see at the Moment the deblocking Bug is fixed in some x264 encodes
I had these ugly Blocking in some of my x264 encodes in Scenes with Rain etc...with 1.5.0.0 no Blocking anymore :-)

EDIT ! :
No, in my Testsample was no Blocking with 1.3.0.0 too.

This sample has the "CoreAVC Blocking"
http://www.megaupload.com/?d=BF2IX6WU

@CoreCodec (betaBoy) it should be fixed in 1.5.0.0 ?
But it is NOT fixed in 1.5.0.0 !

It was the most important Bugfix for me (and for the most people i know)....very very sad

[oddball]

Confirmed. CoreAVC is *BROKE*. ffdshow and Cyberlink's codec have no problem with this x264 encode.

See at bottom of image. Blocks. It looks worse during playback. I get LARGE areas of blocking and mess. It seems to occur during fast motion scenes.

Are those samples made with x264 BEFORE revision 663?

limit vertical motion vectors to +/-512, since some decoders actually depend on that limit.

If so, there is your problem, and solution.

[bakerpr]

I cuold not get core 1.3 and now 1.5 to work with dvbviewer.
Is this a known issue or has anybody got it working?

i use rev 667 (aq patched)

I know ,my last latest encodes seems to be fine with CoreAVC

But "However", thats not the point imho!

The only Solution can be a finally working CoreAVC Decoder, so much Release Delays etc..cant be true that nothing is fixed, Sorry.
Other Decoders are working perfect with it, even with freeware. so CoreAVC is the Problem!

[Manao]

CoreAVC isn't doing anything wrong by not decoding properly a video stream with too long motion vectors, since the H264/AVC standard specifies vectors should be less than 512 pixels long ( though the bitstream syntax allow them to be larger ).

Now, though such a restriction makes perfect sense for hardware decoder, it's silly for a software one. It would be easy to change the decoder in order to support large vectors, but there is nothing compelling them to do it. After all, x264, afaik, was the only one generating too big motion vectors, it was due to some very rarely used parameters ( usually, aq or cqm ), and it doesn't do it anymore, so...

[geoffman]

Any Vista users try 1.5 yet?


Seems to be working fine for me so far on ultimate.

yes, i understand it :)

I only want to say that other decoders have no Problems with such large vectors..thats the Point for me

So, with builds above 663 it should be fixed, even with aq

coreavc 1.5.0.0 works for me with dvbviewer - 1.3 didn't. just when i am using a directshow-deinterlacer dvbviewer crashes sometimes.
and black = grey on my pc when input and output is set on auto-detection.

[bob0r]

I cuold not get core 1.3 and now 1.5 to work with dvbviewer.
Is this a known issue or has anybody got it working?

CoreAVC 1.5 works here with dvbviewer 3.6.1.20
However, the way dvbviewer (and altdvb also) handle directshow filters.... well isn't optimal i guess.

However.... in this case... Premiere-HD and BBC-HD both work fine with CoreAVC 1.5.
The video however does not nearly play as fast/smooth as the same video captured to a .ts

Cyberlink's H.264 decoder that comes with version 7.3 (build 2911 is good) still works best with dvbviewer..... but powerdvd comes with the dvb-s2 card.

[bob0r]

yup x264 revision 663+ should all be fine, blockwise.

--

grey = black i have the same problem, blame nvidia mostly.

Anyways, when you select tv on input and output, you get the most vivid colors and black is black....

Ofcourse use MPC (media player classic) + Haali's Video Render (Options>Playback>Output for playback :))

[oddball]

BetaBoy can you add support for non-compliant large vectors anyway? I have a couple of problematic encodes and don't have the source anymore to 'fix' them.

Thanks.

Hmm, does this mean I can't use CoreAVC for HDTV? Or only that I need a slightly faster CPU? I was planning on getting a DVB-S2 card very soon but if it will only work with Cyberlink I guess that that plan just died (because of lack of deblocking). :(

lack of deblocking ?

[blubberbirne]

bbc hd streams doen't work!

[Jay Bee]

With DXVA deblocking is only performed with 8500/8600 and 2400/2600 GPU's. Not too bad for HD Optical but very bad for HDTV.

And there I have seen it floating around again. So much for the great activation.

That's no big problem anymore in the begining it was but now they should be able to cross finance the consumer loses much better, so i wonder why the Consumer version doesn't yet is free (seems to be clever marketing this way it will allways be talked about the Decoder in a time of Hardware Playback accelleration and soon Consumer Hardware Encoding via GPU) :)

Is there some new activation since 1.3.0.0 ?
Dont know...but all Version was avaibele as pirated Versions somewhere in Net..alltimes, so its nothing new

No concern of mine, i use my legal Retail license

[bob0r]

Sample?
Because all my 100+ BBC-HD samples DO work.

Its nothing new, I just wanted to point out again, that it takes no time to remove the activation...

[CruNcher]

Could somebody check if they have a better Quality Chroma upsampleing now (compared to Mainconcept/Elecard and FFdshow High Quality Mode) (quality problem i told the devs some months ago, can't read anything about it in the Changelog so that suprises me somehow)
Betaboy ???? (or does CoreAVC expect everyone to use Haalis Renderer ?) would make sense for CorePlayer ;)

*hm* after reboot it works :eek:

Till the variable check comes in and then timebombs it ;-)

[BetaBoy]

Anyway... on tap for this Tuesday:

- Purchasing goes live
- A new installer that is Vista compliant
- New serial number for each user
- 14 day Trial version

[BetaBoy]

Also I did not mention this... but one big addition to CoreAVC Professional 1.5, is that it now supports 4 CPU cores. So if you have a quad core system... let us know how it works ;-)

[Guest]

That will be wonderful.

This is one case where I would love to be able to eat my words!

[deets]

yey i have 4 cores :D

ill get the demo.... any 64 bit compiles for use with wmp11 64 or any future 64 bit media players?

not as vital now MS has patched the spdif output to make it work in 32 bit players

[BetaBoy]

There is also the possibility that we will add 'unlimited' core support in the Enterprise Edition. 64 bit? Well I don't want to comment on that atm.

Oh nice, so maybe I can play my losslessly encoded 223 megabit 1080p file at full speed now :p

[BetaBoy]

FYI... its undocumented atm for a reason... So if its broke... you've been warned... but we would like some feedback if anyone has tested... if you can pls be specific on the CPU's and config ur using. Thx.

yeah, my too BBC HD Mbaff too

PremierHD/Skyhd too

[Jay Bee]

bob0r: did you see my question about watching live HDTV?

You said the performance was poor compared to playing TS files. What CPU do I need for it to be smooth? The answer to this question is important to me as it will decide whether I will buy a DVB-S2 card or not.

[bob0r]

@Jay Bee

Its hard to say, in dvbviewer GE the video is flawless, in the normal dvbviewer the video plays less than 25fps....

I use a D 930 @ 3.0Ghz (2 core)
So i guess any Core 2 Duo+ would do? no idea.

Are you using EVR in dvbviewer GE?

[Jay Bee]

Ah ok, thx. If there's another software that works flawlessly then everything's fine I guess.

[Adbear]

Still waiting for a refund since May from these guys and they've now banned me from their forum for posting complaints about the service

Finally got a refund, only took me complaining in the forum and getting banned to do it

[BetaBoy]

Coming here to OT the thread will not get you anywhere and what you were doing on our forums was not following the rules and were warned and then banned... that was your choice, just like it was mine to issue you a refund after months of use. Lets see if you make the right choices on D9.

fast Dualocre is required for 1080 h264...for live or TS playback

[Jay Bee]

Thx. I already played around with these test files (http://x264.nl/h.264.samples/) but I was wondering about the performance loss of live DVB vs TS.

[Dark Shikari]

I can play 1080p (relatively low bitrate, at least) with a 1Ghz Core 2 Duo (2Ghz on battery mode).

[Jay Bee]

Yes but low bitrate 1080p is easy compared to high bitrate 1080i, especially if it's MBAFF.

I couldn't follow your rules as your support forum doesn't allow people to post in it (and therefore makes it totally useless) and as no one was bothering to take any notice of my emails it was the only way to get any attention. Also I never got months of use out of it I got around 6 weeks due to the awful activation you use which means if you have to reinstall you have to get in touch with 'support' who just told me to wait til the new version was released (which took 3-4 weeks the first time) and the second time I was offered a refund as it seemed no one wanted to reset the activation so I could continue using it. It then took 3 months before you finally transfered the money to my account. If the support had been there from the begining I wouldn't have had any complaints, but it wasn't.

[Revgen]

A full bob-deinterlaced 60FPS 1080p clip at 5000kbps worked fine. It was definitely full-motion footage that the decoder seemed to handle fine. FPS was at 59fps the whole time. All advanced X264 features were used. This includes b-frames, deblocking, cabac, etc.

I use a dual-core Athlon 4600+, so I can't really see why I would need Quad-Core. However, I'm going to try encoding to 10,000kbps with all the advanced options and see how that goes.

Pls... I'd like to see some of those results ;-)

[BetaBoy]

Adbear... While I am not gonna make excuses or state specifics in your case or point fingers, I can say (because you gave me the opportunity too) that we have 3 fulltime people on the CoreCodec Support Center who are now doing a hell of a great job via emails, tickets and phone calls daily. Granted alot went on in the early days and we have had holes that needed to be taken care of... and they were. But now with CoreAVC 1.x, CoreAVC QT, CoreAAC, CorePlayer Mobile, BetaPlayer, CoreSVC coming out, we are striving to do an even better job and the staff here is proud of the fact that they have less then a 10 hour turn around average for support tickets. While we recognize there are ppl like yourself and always will be, we will deal with them as best as possible.

Now pls move on, and lets stick to the topic.

[Kurtnoise]

A question for you BetaBoy : maybe this has been already answered but it could be great to add it in your 1st post. So, I've 2 windows OS installed (XP and Vista) on my PC. However, I can't use/install CoreAVC on both systems. So, is there a way to have the possibility to activate the filter on both systems without ordering a new product ?

[ACrowley]

Yes but low bitrate 1080p is easy compared to high bitrate 1080i, especially if it's MBAFF.


my A64 X2 4800 plays "all" H264" Content...even with extreme high Bitrates and or MBAFF...

Also with Cyberlinks Decoder without DXVA

No need for a Quadcore to decode h264 ,when youve a "fast" Dualcore (2ghz+)

If I remember earlier conversation on the subject it's for single OS only.

[Kurtnoise]

For Windows OS you mean...because what about mplayer's patch (http://code.google.com/p/coreavc-for-linux/) to work on Linux ? :p

Currently, I'm able to use CoreAVC on my XP *and* on my Debian.
