CoreCodec/H.264 Codec "CoreAVC"

[Bathrone]

It's a healthy thing foxyshadis. The company could leverage this upswelling of community interest and support to their sales advantages. Insightful companies should be excited to see interest for unreleased products.

[clsid]

They should have released an 1.1.x version with some bugfixes. Now many people are waiting for 1.2 before they will buy the product.

[Sharktooth]

right... im still waiting for h.264 lossless decoding that was in in 1.1.0.6beta (or something).
half of my encodes are h.264 lossless so, i wont buy it until it will have that function.

[Hans Ohlo]

i hope the time goes into coreAVC and not into the new licensing model ;)

[HookedOnTV]

Betaboy with the latest pre-rc1 build 5536 pf vista ultimate, CoreAVC pro (latest version) will crash wmp11 if the user closes the video playback before the end of the file. if the user allows the footage to complete, its ok.

I'm having this problem in MCE2005. Freezes up if you hit the stop button.

[sjchmura]

Btw, when will support for h264 transport streams be added - is that a 2.0 feature??

Which files are you having problems with? I have AVC in TS files that work.

[ChronoCross]

TS support has been there since the last version.....

Im still waiting for GPU assisted decode which im sure was promised as comming soon approx 6-7 months ago when i purchased the software, if i knew it was going to be half a year, to a year away i would have just got something else.

I'd check there forum for information, but its still got the hacked stuff up, which makes me kinda laugh as that would mean.

1. Nobody from core cares enough to visit there forums regularly and have actually noticed.

2. They would rather have the hacked page up, rather than a blank page.

The included TS splitter by Haali doesn't work very well. But he is working on a new version.

[ChronoCross]

what are you talking about......it works perfect for me. I think it's something on your own machine.

[sjchmura]

THe Haali splitter also breaks nero recode so you can't use both on the same machine.

I tried a sample from the UK (h264+AC3) TS stream that works with nero filters but not coreavc (or the version in MPC). Is the MPC version simply outdated??

[sjchmura]

ChronoCross,

Haali breaking other programs - notibly Nerovision adn NeroRecode 7.57 is well known and documented by Ahead/ATEME.

[ChronoCross]

that's because recode is very bad when it comes to encoding. it has so many issues interfacing with directshow. We have to deactivate half our codecs to get recode to work.

my favorite glitch is why I try to load a file and it says cannot then I can longer add anything to the compilation and it won't allow me to until I restart the entire machien

[CruNcher]

I agree with ChronoCross here Directshow gets problematic if you have hundreds of filters installed from 100 of different vendors, because every one is doing his own thing and especialy companies like to make their filters incompatible with others by nature, years ago it was the "dll Hell" that made our life hard today it's the Directshow Hell :P

Toff made a very nice "Chain Load Analyzer" in Matroskadiag that shows you wich Directshow filter trys to get into the Chain and at wich time that might cause a problem, it helped me alot in debuging Directshow Problems and find those "problematic filters" :)

For Example Elecards Colorspace Converter likes to get into the chain when every it can, and sometimes you don't want that :P

[HookedOnTV]

Betaboy, can you comment on the issue with MCE2005/WMP crashing when you hit the stop button? I see a thread on your forum with many other users having this problem and nobody is getting any kind of acknowledgement. Don't have a keyboard hooked up to the Media Center pc so having to vnc in to kill Media Center through task manager everytime I watch a movie really sucks.

[Hans Ohlo]

i can confirm this MCE2005 problem here too. it is very annoying even with a keyboard nearby.

[Jay Bee]

Be sure to do some x264.exe --interlaced testing :)

I've found a way to get x264 interlaced files working:

-add the "ffdshow raw video filter" to the playback graph
-set the deinterlacing method of CoreAVC to "Directshow"
-set the deinterlacing method of ffdshow to "Bypass" and click "Swap fields"

Would be nice if CoreAVC could do this without any workaround.

EDIT: It also works for MBAFF files created with Mainconcept so I suspect the problem is with CoreAVC not x264.

[BetaBoy]

bond... I have worked on a comparison... but I feel it best to those that are neutral... atm in 'software' we are still about 15-20% faster.

not to get too OT... but get ready for a NEW CoreAVC decoder on Thursday Nov 2nd. This will feature;

- Many fixes like the colorspace issue
- New Haali splitter
- Speed increase
- New Installer
- New registration process

We will be relaunching CoreAVC.com next week as well.

Sounds good! Is this version 1.2 or 1.1.x? Will it include hardware (GPU) acceleration? Thanks!

[Thunderbolt8]

would really look forward for a speed increase, especially with hd h264 files. these ones still need a shitload of cpu performance to be played fluently.

What about GPU acceleration ???

[Thunderbolt8]

im not familiar with coreAVC, does it support external subtitle files (srt, sub) ? if not, I would really look forward to such a implention.

[Sharktooth]

It's a video decoder! Not a subtitle renderer!

[BetaBoy]

;-> lol

[Thunderbolt8]

well there are people who prefer original language movies, which can be found somewhere in the net sometimes and then (mostly english) subs are needed to understand that japanese/chinese/whatever language. has nothing to do with being a subtitle renderer. vlc also supports that.

[GodofaGap]

CoreAVC is not a player. It is 'just' a DirectShow decoder. And yes, you can watch subtitles in DirectShow using VSfilter.

[Seb.26]

yes ... ... but why add subtitles in CoreAvc ??? :confused:

[Sharktooth]

Exactly.

@Thunderbolt8: Just install VSFilter and you can watch subtitles with ANY directshow player using ANY directshow video decoder.

[maxleung]

What about closed captions? At least for mpeg2 broadcasts, CC is usually embedded in the video stream.

Anyways, I would prefer CoreAVC because its software decoding is quite good (despite the colorspace issues), without worrying about specific display driver revisions which may break hardware-accelerated solutions.

[Thunderbolt8]

Exactly.

allright Ill give it a try
does this actually also refer to those external .srt, .sub files ?

I thought CC was embedded in the ts stream, not the video data. Either way, either the splitter or the decoder could make a text-out pin available to vsfilter to render.

allright Ill give it a try

Yes, if you install vsfilter you can configure it to look up .srt, .sub etc in the same folder. I think it's set to by default.

[bond]

BetaBoy, the mainconcept decoder thread is not for promoting coreavc. posts moved

now that's what we wanted to hear for a long time. november 2nd, i can't wait ;)

thx

will the windows xp MCE freeze problem be solved? (was/is it a coreavc problem or splitter problem?)

[Thunderbolt8]

Yes, if you install vsfilter you can configure it to look up .srt, .sub etc in the same folder. I think it's set to by default.
bleh, I just noticed that the subtitle file and the movie file both need exactly the same name, apart from the file ending. thats not working for me again then, since I always add "Eng subtitle" or such at the end of those sub files (in case some people who are not that familiar with all that stuff also want to see the movie, so they know what these files are), I cant use it. and even in case I'd start renaming the sub files now, I have already burnt dozens of dvd with different named subtitle files, so this is not a solution for me.
any other alternative available ?

[foxyshadis]

It does have an open button in the filter. You can also copy them into one of the folders listed under paths.

Otherwise you can modify the source to attempt an autoload with your filenames, if you have any specific format you like to use.

Last option is probably loading it into avisynth with directshowsource and a textsub() with the subtitles, then play that. Slow, though.

[Episodio1]

"since I always add "Eng subtitle" or such at the end of those sub files "

If the movie is called: movie.supermegaHDTV.avi you can name the subs file: movie.supermegaHDTV.ENGLISH.srt

You can put even many subs files:

movie.supermegaHDTV.SPANISH.srt
movie.supermegaHDTV.FRENCH.srt

And you'll be able to choose one of them in the right-click vobsub menu.

If you add an extra dot, then VSFilter will autoload them. Example:

movie.avi
movie.something.srt

(it will display 'something' as the language name)

Edit; damn, a few seconds too late :P

All... a quick review of CoreAVC showing its speed...

not very detailed or comparing it to other solutions... anyone from MainConcept want to give bond a demo of the worlds fastest H.264 'SOFTWARE' decoder?

What about STFU?
Everyone is asking about coreavc and GPU acceleration when betaboy already said he cant comment on it.
The guy (betaboy) should have the patience of a saint coz even if im not a coreavc dev, i cant stant all those requests about GPUs.
Stop it and wait for the next version!

But the definition will be better in 1.2 version?because powerdvd has a better definition(but slower) than coreavc

I have to agree, I fail to see all the fawning over hardware accel...
seems like putting a carbon fibre body on a car to me
nice but not neccessary.

dont let them get to ya betaboy :)

lol ... and about VTFM ... Something to say ? :D ;)

The think which really make me "bad spirit" in this thread ( be sure I'm not really like that ) is that "the guy" (and his team) promise (and sell) to us GPU acceleration (from several months now : about 1 year), and from this date the only things he write to us is :
1) Our decoder is the faster of the world ...
2) ... so imagine when whe will provide GPU acc ...
3) everything else is bad, << CoreAVC powaaaa >> ( [Edit3] : and yes of course it's true ... )
4) GPU is really comming ... but it's too secret ... wait few days, it's for tomorrow ...
5) ... continue to buy our product please ... you wil have the best GPU acc in few days ...
6) ... look this benchmark : other products are bad ...

It's a bit too "marketing" for me ... sorry for bad spirit but ... it's like that ... it's life ... :o

Imagine nVidia/ATI do the same ... just imagine the post about this ... lol

In any case, have a nice day Sharktooth ( and others guys on Doom9 too ), and I hope you will understand my strange English ... lol ... :o

[edit] PS: my first post was more a joke than other things ... but it's life ...

[edit2]
Have fun
Seb ( ready to catch the god - hell's big fire :) )

[CruNcher]

I don't like this either especialy, because we all know that at least Nvidias Driver are not 100% optimized yet and no Cabac is working on the GPU wich takes a big count of the CPU @ decoding H.264 sure @ the moment CoreAVC is the fastest and impressive in it's Software Mode but this could change rapidly my god this is the IT Biz today is allready what was yesterday, but for sure Mainconcept didn't do themselves very good claiming to have the fastest Decoder wich is not the true from a Software Point but real marketing lies and CoreCodec didn't lied in those regards yet to it's customers, allways keep that in mind. And seeing those results should make everyone clear that Hardware accelleration isn't up to it yet only in Multitasks it can help as of now for example DVB watching via BDA you have alot of other threads to handle on the CPU not only Video also the Audio to a regard and all kind of parser and buffering stuff wich most probably would be better with haveing alot done on the GPU then on the CPU and keep the CPU free for the other tasks that's the only thing i encountered small speed differences so far with CoreAVC's Software Mode compared to Nvidias Hardware accelleration.

- New Installer
- New registration process

Doesn't really say alot when you call these new features. Nobody cares what installer you use to be honest and your registration is just a step backward from the very simple install we had before. So calling these new features is a bit of a joke.

What about STFU?
Everyone is asking about coreavc and GPU acceleration when betaboy already said he cant comment on it.

As already mentioned perhaps if he didnt go around shouting about it and how it was comming soon, 9 months ago, then perhaps people wouldnt be continually asking about it. I paid for this software 7-9 months ago, thinking that GPU acceleration was comming soon, and i've still got nothing today. Not only that, but he flatly refuses to even acknowledge some of the issues like the media center bug thats been there for ever.........and would rather spend there time, playing about with the 2 great features mentioned above.

[Selur]

...and your registration is just a step backward from the very simple install we had before.
Here I disagree, a nice registration that allows you to download new updates without much hassel would be nice.

Cu Selur

[Shinigami-Sama]

just because you've not the patience to wait untill something is realeased and then go and complain about it...
some of us are waiting for it come out before paying
it's the safest choice ;)
my vote for it comming out is the next *.5 release
