CoreCodec/H.264 Codec "CoreAVC"

[HookedOnTV]

Just for a reference... what time zone are we using for the definition of March 31st?

[Sirber]

all of them are realllllly great :D

[ChronoCross]

they still have a long way to go if their using hawaii standard time.

I heard all Core activities take place on the Line Islands.......

[BetaBoy]

All... we are working on 3 seperate issues atm... one installer, one code based and one related to the site. It is likely a nogo for today.... and if that is the case I want one more day to QA this.

I'll post a follow-up in an hour or so.

[Sirber]

I'll be sleeping :'(

[travisbell]

Bummer guys! Can't wait for April 2 ;)

[Sirber]

April 1, here I come. going to sleep ;)

[fields_g]

Been checking the net all day for this release. I like the new "April Fools" message on the site.

I think you are intentionally building up the suspense!

[BetaBoy]

We are gonna give ourselves one more day to QA this and release it on Sunday. Sorry for the delay...

[neo squidward]

Wow! Real taskmasters making the poor devs and testers work on the weekends. ;)

[BetaBoy]

Most of us here work 7 days a week now... were playing catchup... CoreASP is next ;-)

[ChronoCross]

lol begining to look alot like microsoft heheh....good luck lol....only a 60% rewrite by sunday =P

[Selur]

if it's like microsoft a 60% rewrite would also be needed after the release ;)

[3ngel]

CoreASP is next
:eek:
I hope the price is the same as CoreAvc standard :D

[lexor]

forget MS, this is beginnig to sound like the whole Half Life 2 thing, people where yelling "but the engine was done over a year ago", with the amout of complaining you'd think Gabe was holding back a cure for cancer. lol. Take your time guys, quality first.

P.S. MS doing 60% rewrite is FUD, I don't think even the behemoth that is MS (especially since it's a behemoth) can do a 60% rewrite in 2 months launch delay.

[SeeMoreDigital]

CoreASP is next ;-)Cool.... can't wait :D

[tomos]

ASP? forgive my noobness but isn't that what other mpeg-4 codecs like xvid and divx are?

[Sirber]

ASP? forgive my noobness but isn't that what other mpeg-4 codecs like xvid and divx are?yes, MPEG4 ASP

[tomos]

yay i was right :D heh

[BetaBoy]

Not to get to OT... but our DS port for CoreASP should be pretty straight forward... although Toff indicated a few things that has to be done... the only things missing that picard indicated was Post Processing (and something else that is not coming to atm).

Anyway... CoreASP itself will likley not have its own site but be part of our 'Core Media!' codec bundle we will be selling along with CoreAAC+ v2.0, CoreMP3, etc.

I'll talk more about that later on.

[jblade]

Seems like CoreAVC is becoming another Duke Nukem.... jk :)

I don't mind waiting.

[tomos]

have you done any testing on the ASP codec yet? i mean to give you some idea to the speed of it compared to xvid/divx?

i know someone who encodes a lot and a codec comparable to those but faster to encode would be huge :)

this is decoder, not encoder for ASP betaboy is talking about.

and I won't really care if ASP decodes at the same rate as ffdshow or xvid own decoder (same for mp3, and aac) since they are lite anyway. I'll get them as package deal so I have an all in one solution. AVC speedup and TCPMP (the new one they all rave about) are good enough selling poits for the whole package imho.

[tomos]

ahhh, ok. guess my mate's stuck then :)

It all helps when playing hi-def sources :)

[CruNcher]

tests between ffmpeg.plg and CoreASP with tcpmp show that its much more optimized if the DS filter will be faster then the ffdshow (libavcodec) decoder is another question

[videomixer9]

even divx decoder uses only 6-8% on many ASP videos nowadays on my pc ... newest divx decoder even beats ffdshow for most content o_O so CoreASP must have a real good argument to be used, especially as payware ...

[SeeMoreDigital]

even divx decoder uses only 6-8% on many ASP videos nowadays on my pc ....Surely not when playing hi-def 1280x720 at 23.976, 25, 50 or 59.94fps and/or 1920x1080 at 25 or 29.970fps.

When playing 1280x720 at 23.976fps I'm at around 80% with XviD.ax and 70% with FFdshow :eek:

[videomixer9]

best i found was a 1024x576 video in ASP on my HD and that plays at around 15-25% depending on motion speed with DivX 6.1.1 decoder incl. reclock and vsfilter interfering in VMR7.

umm... yeah, that's a lot. that's my AVC usage, you sure something isn't going wrong there?

[SeeMoreDigital]

umm... yeah, that's a lot. that's my AVC usage, you sure something isn't going wrong there?In that case, can some of you try the following Thank You For Smoking (http://www.divx.com/movies/browse.php?categoryID=3) 1280x720 @ 23.976fps encode and report back?

I'm peaking at around 65% with FFdshow!


> BetaBoy,

Might be time to start a CoreASP thread and get some links to some high-def test files established ;)


Be seeing you!

ok SMD, tried it, and I don't know, it might be my 2.2GHz athlon 64, but I get 22% cpu usage pretty much stable, when I seek far ahead, it jumps to 40% for like a second, but then back down. ffdshow+mpc here.

same resolution AVC trailer would fluctuate between 50-70% usage depending on the scene.

[GmorG McRoth]

This trailer crunches my CPU (3.0 GHZ Intel Prescott) at about ~50% (maxes out one Threed) when mplayer deblocking (with accurate deblocking on, ~35% with AD off) and ~17% without deblocking. Played with ffdshow-20060226 and MPC

For comparision its about 12% for XVID (without deblocking and again 50% with booth deblocking option checked, but without deringing).

DIVX does about 17% without deblocking (and film grain off) 45% with deblocking ON (and deringing, Film Grain off).

3viX does about 19% without deblocking, 25% with PP slider half way (my best gues its booth color spaces deblocking) and about 30% when PP slider is all the way up (it's multithreeded)

[3ngel]

I would be interested in a "CoreMpeg2" too, in order to decode Mpeg2HDTV. Actually the fastest ds decoder is Mpeg2Dec Filter.
So it would be a great thing to have an even more faster mpeg2 ds filter, with some options like spacecolor forcing, or deinterlace.

as someone pointed out above, post processing takes alot of cpu, do you use any? I personally don't have anything that can benefit from it (and that clip certainly wouldn't).

EDIT: Here's what I get when I play the same file using XviD DSdec in GraphEdit: -

SMD... I'll start a thread in the ASP forum so bond does not have to start splitting this thread into 20 new ones ;-)

I'll look forward to Bond moving all relevant ASP posts...

@3ngel:

Are you referring to the mpeg2dec DLL for avisynth? I didn't know this could be used as a DS filter. If so, how?
I think he's just talking about make a script which opens up the video using mpeg2source and loading the avs file in the player. dunno about the speed of that, though.

[3ngel]

No, i'm talking about a real ds filter named that way.
I post the attachment of the .ax.

[videomixer9]

isn't that gabests directshow wrapper for libmpeg2? Moreover this has not even anything to do with ASP and even less with AVC ...

[jblade]

When is it coming out? I thought today?

[GmorG McRoth]

they have 30 minutes more to make it in time on GMT +1 time zone :)

[videomixer9]

Guess they are using Microsoft Vaporwarizer 2006

[breez]

Well, they are US based so there's a few more hours left.

[jblade]

My dollar bet is that it gets delayed once again.

[tomos]

not sure why since the betas worked well. unless possibly there's something up with the purchasing systems? thats my bet as to the cause of a delay

[futurex]

just change the release date to july already!
