CoreCodec/H.264 Codec "CoreAVC"

[ajp_anton]

hope a 64bit version of CoreAVC comes soon as MPC-HC 64bit version was just released:)Really? I thought I'd been using the 64-bit MPC-HC for almost 14 months...

[BetaBoy]

CoreAVC 2.0 will be out in the fall and yes 64 bit is included. Guys try and keep it OT.

[Snowknight26]

Will that include a new version of Haali's splitter?

[popper]

Will the following issue also be addressed in next version of Haali Media Splitter?

http://lists.matroska.org/pipermail/matroska-devel/2009-August/003533.html

the Most supriseing thing to me after looking at that linked ML is that given Haali Media Splitter is supposed to be used a lot , theres Very few postings on that mailing list, implying theres very little progress or new additions taking place in the codebase and thats a shame.

its also interesting that Colleen Williams (Smart Marketing & Events) MS says
"our end goal is to have a positive end user experience with Windows "

but they cant be bothered to actually put an mkv container ability in their MS xbox360, or even follow the DNLA spec with the "send to" DNLA stuff thats supposed to be in the MS windows 7 but not in the latest 360's firmware.

so nothing like a positive Experience with that MS to MS 360 product combination,
but you can get a reasonable "positive Experience" with an MS to Sony Bravia KDL-46W5500E DNLA HDTV and several others, And to a Sony PS3, how crazy is that, its not 'Smart Marketing' or a good turn of 'Events' thats for sure.

perhaps somone on that list or in contact with her can pass the mkv and 360 firmware DNLA requests on, and get something sorted, then CoreAVC used with PMS might be far more effective with direct DNLA streaming mkv playback on the 360 as a DNLA device one day instead of the very limiting mp4 options people need to use there today.

That's what you have when the source code of great tools is not available: Haali's splitter and madshi's programs come to my mind. When the author fails we're doomed. madshi is busy with RL affairs and we don't really know the situation with Haali, but should be similar. A shame indeed. If the author is not going to work on it and a lot of people are "dependant" of his work, the best option is to open-source it so at least someone could continue with the project. I guess you can't comment on this BetaBoy?

[BetaBoy]

Haali and I have talked about open sourcing the filter several times, although not in the past year or so. I'll ping him on it so maybe we can do what we do for Matroska under a dual license (LGPL/BSD) as that seems to make the most sense. But there is some pretty cool code in their that Haali might not want to let go off (easily).... I'll give it a shot and ask him again.

vB;1313212']I've got the upscaled ITVHD stream working ok now, must have been a problem with DVBViewer after all.

Have you had a look at it yet Paul? They are still showing upscaled ITV1, lets hope it stays that way...


It's not bad but 4HD's upscaled stream looks much better (fewer jaggies etc)

but I think that's in 1920x1080, and I get it through Virgin cable so it's still in MPEG2!

hi Nick , not seen you for ages, and i cant even remember were those BBC DVB-T MBAFF and tools to use/edit threads took place now.

virgins headend Mpeg2 re-encode of the HD feed always was pritty bad (VM spokesperson: "We Use Mpeg2 Because we can." LOL, because you dont actually have an AVC/H.264 capable STB installed in peoples cable homes through bad long term planning more like),
but im wondering now with the large drop in bitrate reported here weather thats going to be problems with the below DVB-T2 coming online or more likely it dropped because of it.

regarding the change over of the BBC Encoders i cant see anything on the BBC blogs pages about it currently!.

but there is a potential mass of users about to get the DVB-T2 HD feeds soon.

i wonder if this Encoder change is anything to do with the Massive BBC winterhill NW area broadcast coverage towers coming on line soon for the start of the DVB-T2 HD transmissions role out as mentioned by Graham Plumb, the Head of Distribution Technology, BBC Operations Group.

"17:00 UK time, Wednesday, 24 June 2009
[The Editor: In our recent open post we had several questions about the roll-out of Freeview HD. This is the first post on the blog from Graham Plumb, Head of Distribution Technology, BBC Operations Group.]

The plan is still to launch Freeview HD on December 2nd at the Winter Hill transmitter serving Manchester and Liverpool. The plan has always been to roll Freeview HD out around the country following switchover and Winter Hill was selected as the first achievable transmitter. There will need to be a retrospective upgrade of regions that have already switched.

The originally mentioned date of November came from the fact that Winter Hill starts to switch over in November. But it was quickly realised that the BBC's second Multiplex (Mux B) that is being converted for Freeview HD actually switches over on 2nd December at Winter Hill.

The March 2010 date in the Ofcom document is simply the last backstop date by when Winter Hill has to be on air to comply with our licence conditions. They've built in a contingency (as already happens in switchover licences).

The BBC has been working on plans to deliver early upgrades to some stations (serving high populations) that are late in the switchover programme and would otherwise have to wait long for Freeview HD.
..."

its seems like betaBoy and core might have some more mass of interest in decoding this when the Freeview DVB-T2 HD on December 2nd 2009 at the Winter Hill transmitter serving Manchester and Liverpool and pritty much the whole NW as the second most powerful transmitter in the UK comes online for mainstream DVB-T2 HD transmission Finally.

im assuming there may be a few problems to, that need sorting out sooner rather than later, but at least DVB-T2 HD is finally getting out, will coreAVC and the 3rd party DVB-T Transport stream and MBAFF editing apps be ready...

[kieranrk]

In fact we'll be using DVB-T2, and it's pretty unlikely that PC equipment will be available for a while after channel launch.

[popper]

thanks for the reminder kieranrk, im usually good at remembering that, but its been a while since i revisited DVB-*2 and i forgot...

[halsboss]

CoreAVC 2.0 will be out in the fall
Um, whats "the fall" ?

[popper]

Um, whats "the fall" ?

its not when your walking down the road, then suddenly slip and fall on that winter ice, but rather the Autumn when the trees leaves turn brown and drop to the ground, and football starts to get interesting again , or the 3rd finantial quarter if you prefer, he's refering to :devil:

[J_Darnley]

Autumn. It is what Americans call the season between summer and winter.

Would be good if people could use Q1/Q2 or something like that, as the rest of the world has no idea about the US seasons.

OC this "fall" starts tomorrow, as the first day of Autumn, looks out the window, yep , the trees leaves are starting to turn brown...

Nice pic.

We only fall down when the kangaroos bounding at full pelt knock us over, or an opposition footy player tackes us. Ice is what you get from fridges and put in an eski to keep the beer cold.

Still no the wiser when your autumn is. Hang on, other side of the world and someone said tomorrow so I suppose its 1st September which is our 1st day of spring.

Re Q1 Q2 etc, it depends on your definition too, some go by calendar year and some by tax year. Our tax year is 1st July-30 June; I think our xmas is the same as yours.

Cool ;)

If he's going to work on it, fix bugs, etc. open-sourcing it is unnecessary. But you know better than us how the situation has been in the past years...

[clsid]

Is there a preliminary changelog (or roadmap) for CoreAVC 2.0 and HMS x.x? That would give us a nice idea of what improvements we can expect sometime between now and December 21st.

[lych_necross]

What happened to this thread? Lately, most of the posts seem to be OT. Lets stay on track people. :readrule:

[BetaBoy]

We are continuing to work on CoreAVC 2.0... in fact I could post a long changelog, but will hold off for now as we are still doing more. The latest of which is the recent changes to the new CUDA SDK. Our goal remains the same, to get it out around the time that Windows 7 is released.

i like to have bought a license :)

Yeah! Me too :)

Hope the upgrade will be free for thos who have bought a 1.9.5 license..

[Cyber-Mav]

i wonder if coreavc 2.0 will be as fast as or faster than divx h264 decoder.

[BetaBoy]

i wonder if coreavc 2.0 will be as fast as or faster than divx h264 decoder.

Let's define 'fast' as CoreAVC 1.9.5 is still faster then the DivX decoder on most CPU's. However in every test we have done with 2.0 here, there is no doubt it 'is' faster on all CPU's. But, I'll leave that for you all to tell us when we release it.

BetaBoy, would you be so sweet as to coax Haali into helping me debug a really pesky issue (http://forum.doom9.org/showthread.php?p=1321778#post1321778)? Started happening on my desktop too so that's pretty much put my encoding to a halt. Can't test CoreAVC anymore. D:

[ranpha]

A couple of questions:-

The upcoming CoreAVC 2.0 decoder, will it be supported under Windows XP?

Can potential buyers be able to pre-order it? Kinda like Windows 7 is? Maybe those who have pre-ordered can have access to a CTP build or something? :)

[honai]

How did this turn out to be? Really an issue with Haali Splitter? And if yes, will this be fixed in time for the next release?

This was reported in this thread a while ago... and the bug is unrelated to the splitter. Read the report closely.

[Merkie]

I'm having issues with CoreAVC (I think) & Windows 7. It works fine, even with CUDA enabled, but after an hour sometimes the framerate drops to about 10fps, it's like watching a slideshow. Things like pausing/unpausing and closing some Windows often help to retrieve smooth playback. I can't give any more details because it's hard to reproduce the problem. However, it's still annoying as hell because everytime I have to get up and walk to my computer to fix the framerate. CPU usage is practically zero when this issue occurs.

So I have two questions:
1. Is this issue known to any of you? Is it even CoreAVC/CUDA related?
2. If not, what should I do when the issue re-occurs? What kind of information should I gather that would be useful to you?

Software used: MPC 6.4.9.1 + AC3Filter + CoreAVC 1.9.5 (CUDA enabeld) + Haali MKV splitter (and Haali renderer enabled).

[DeathWolf]

That issue looks like your gpu is overheating/switching to a lower energy consumption mode.
Have you checked the temperature curve?

[Merkie]

I just noticed I had CUDA disabled (probably did that earlier in an attempt to resolve the issue), so I doubt the GPU is overheating. Also, CPU temperature is the same as always.

[pankov]

HI
I've been using CoreAVC since it's first version and was pretty pleased with it's performance and quality. Recently I noticed that I have problems with the Hardware Deinterlacing when used with VMR9 or EVR. I thought the problem was either with my hardware or windows installation since it was more than 3 years old XP Professional. Recently I did reinstall my XP (SP3) with all updates and most recent drivers and DirectX and .NET 3.5 and sadly the problem is still there.
With EVR I don't get any deinteralacing ... which I suppose is normal since I use it in WinXP ... can somebody confirm/deny this?
With VMR9 it seams like there is problem with the field order - I don't see any jaggies but there is no fluid motion but total jerkiness.
With Overlay Mixer or Halli everything is butter smooth.
On this PC I use Gigabyte P35 mobo + Intel Quad Q9400 + ATI 4670.
To isolate the hardware as the source of the problem I build a totally different PC with NVidia GF9400 chipset and I decided to put Windows 7 on it.
The problem is still there and sadly in Win7 Overlay Mixer doesn't work (which I think I read somewhere that is normal) so I'm very frustrated now.

What can I do to get smooth playback of interlaced H264 content (50Hz 1080i - EurosportHD / BBC HD)?
What do you guys/gals use?

If needed I can provide samples but I doubt the files are the problem.

[BetaBoy]

Internally here at CoreCodec, Haali has just released the first 32/64bit version of the splitter that now officially supports the Windows 7 RTM. This build features many fixes, but more importantly is that is removes the shell/explorer support. The Matroska thumbnail integration maybe released at a later date as a separate installable option.

We are testing now but likely this will come out right before the Win7 launch and will be included in CoreAVC 2.0 as well.

[Cyber-Mav]

will coreavc 2.0 work in windows media player in windows 7? so far im struggling to get any external codecs to work in windows media player. using media player classic home cinema insted.

[BetaBoy]

I'm not gonna comment on Media Foundation at this time.

[Hans Ohlo]

you should.

[pankov]

Guys,
any comment on the problem that I've posted a few posts back?
http://forum.doom9.org/showthread.php?p=1329406#post1329406

[BetaBoy]

you should.

OK... we have a possible work around for MediaFoundation that allows the Haali Splitter and CoreAVC to be the priorities in MF for WMP and MCE in the Windows 7 RTM.

Anything more? ;-)

Note however.... there is still work to do... so don't excited till we validate it.

[hajj_3]

hope to see a beta of coreavc 2.0 soon, 12 days till win7 is in shops.

[BetaBoy]

It will be after the Win7 launch for sure.... but we are progressing nicely. On the OEM side this week and to be included in our upcoming CorePlayer 2.0, we have now added support for ARM Cortex / NEON.

[Hans Ohlo]

one request i have for future coreavc and haali versions. if you have videos with non square pixel aspect ratios coreavc dismisses them and displays them wrong. when switching to ffdshow as avc decoder everything is fine. i tested this with vista and 7 (RTM) media center.

[thewebchat]

CoreAVC passes the PAR of my files just fine. This includes Matroskas with aspect information in the headers and one AVI with the PAR coded into the video bitstream. Are you sure the problem doesn't lie on your end?

[Hans Ohlo]

does it work in media center?

[thewebchat]

Should I care?

[blubberbirne]

It will be after the Win7 launch for sure.... but we are progressing nicely.

hm, first you say, it will released before Win7, and now it after release :eek:

I hope that CoreAVC can handle now Interlaced Streams. Thats very important for DVB usage.

[BetaBoy]

Oro?... it's called an 'update'... with the changes that Haali is doing with the splitter to make it Win7 compatible in MediaFoundation and the continuing 2.0 changes, naturally time lines will shift.

blubberbirne... What do you mean by interlaced? If it works fine now... and there is no diff in that regards to 2.0.
