Ok, seems like I'm doing something wrong, I downloaded tcpmp.win32.0.71g.zip (from http://picard.exceed.hu/tcpmp/test/) and ice_age_2-tlrD_h1080p.mov (from http://www.apple.com/trailers/fox/ice_age_2/hd/), remuxed ice_age_2-tlrD_h1080p.mov into ice_age_2-tlrD_h1080p.mp4 using Quicktime 7pro.
Then I unziped tcpmp.win32.0.71g.zip, started player.exe, ignored the message about the aac audio decoder, opened the mp4 file and tried to play it. => 100% CPU usage and a no way watchable (to slow, skipping frames) playback. Playback works fine in TCMP using ffdshow for Audio&Video decoding, no problem watching the mp4 smoothly. (70-99% CPU usage, would be a bit less if I would use ffdshow to convert the aac stream on the fly to ac3) Shouldn't this work? Am I doing something wrong? Cu Selur Ps.: running WinXpro 32bit with newest updates, 2GB RAM, Athlon 64bit 3500+, display resolution: 1920x1200. |

selur, you need to get avc.plg, which is available together with the aac.plg in an extra package on the page

Ah, okay, thx.
Just tested the directshowdecoder. CPU usage dropped to 46-75%, nice. Thx, bond worked fine, CPU usage even dropped another 5%. Cu Selur Ps.: Nice work CoreCoded-Team Last edited by Selur; 6th January 2006 at 19:59. |

I hope CoreAVC can have these color conversion options :
ColorMatrix("Rec.709->Rec.601") ColorMatrix("Rec.601->Rec.709") ColorYUV(levels="TV->PC") Because vmr7&9 seems to need PC scale YUV and overlay needs Rec.709 for HD. |

Hmm, just thought, that applying brightness before rendering on more deeper level is more effective...

I did a quick test using TheGreatestGame_HD_AVC.mp4 trailer (1920x1080p) available from nerodigital.com and timeCodec from Haali. I'm running an AMD X2 4400+ @ 2420 MHz.
Nero: 52.3 fps CoreAVC: 45.3 fps Ateme: 30.6 fps As you can see CoreAVC shows really good performance it's only beaten by nero decoder which exploits both cores of my CPU while others don't. |

the values he posted are for plain decoding (eg via avisynth). for playback (via directshow) the display fps shown by haalis tool are important and these are in bobololo's setup: CoreAVC: 45.1 fps Nero: 36.1 fps Ateme: 30.6 fps as you can see coreavc is faster than nero for playback, even altough nero is multithreaded and coreavc isnt, so i wouldnt say nero is able to beat it at all

Athlon XP 3000+, 1 GB Dualchannel DDR333 RAM, TheGreatestGame_HD_AVC.mp4, Haali timeCodec
ffdshow 04 Jan 2006 User: 173s, kernel: 0s, total: 174s, real: 180s, fps: 21.1, dfps: 20.3 CoreAVC: User: 107s, kernel: 0s, total: 107s, real: 111s, fps: 34.1, dfps: 32.8 Plays fine and in sync with CoreAVC and stutters otherwise, I guess I say byebye to ffdshow, too bad I cannot use quicktime decoder in timeCodec as I'm sure that one would be by far slower, tried with an apple trailer that stutters around totally in Quicktime Player and test result was this, besides the totally fluent playback in the player (x-men_3-pre_teaser_h1080p.mov): User: 42s, kernel: 0s, total: 42s, real: 48s, fps: 55.7, dfps: 49.4 Apple ever going to update their crappy decoders? I got lots of ppl that think their PC is not ready for HDTV stuff because of the bad performance of Quicktime ... Hope CoreAVC will be improved and regularly released soon!

What a fabulous little MPEG-4 AVC decoder....
With it I've been able to play some 1280x720 samples quite perfectly, samples that previously stuttered Great work guys.... once AR signalling detection is included, it will be a brilliant little MPEG-4 AVC decoder Cheers

To come back to the topic, our main interest here is to compare the raw performance of the decoders no matter what there is around (dshow, displaying, rendering, etc.). And this raw performance is indicated by the fps entry from timeCodec as Haali explained to you. I provided the figures corresponding to it in my post above. The display fps (dfps) gives the actual framerate of the whole display graph if I understand correct and therefore it includes many things like parsing, rendering, output color conversion, displaying, etc. that are to my opinion out of the previous scope. I don't know the reason why the dfps is quite lower with nero decoder, but it's rather abnormal since I used the null renderer in which case the fps should be close to the dfps (as it's verified with other decoders btw). I have the feeling that for some reasons, an unknown additional filter had been added in nero's case and drastically slowed down the display graph given its poor result. Whatever the cause, it doesn't change the raw performance figures showing that nero is faster than CoreAVC and there is no discussion possible here (unless there are some issues in the way timeCodec does its job). And as a conclusion to my 2 cents' comment , I would suggest you to spend your energy bitching CoreAVC devs to exploit MT optimization to definitively bring it far ahead from others decoders instead of trying to arrange actual facts that don't please your taste . That would be much more useful for the development progress ! Last edited by bobololo; 8th January 2006 at 04:51. |

i simply posted the info you left away, i see nothing wrong with that Quote:
imho the main interest is how nero and coreavc perform during playback, as currently avc decoders are as good as always used for playback if nero does some wierd colorspace conversion or something else during playback which slows it down, it still makes it slower than coreavc during playback therefore the dfps value is interesting and shows that during playback coreavc is faster than nero you should have at least provided us that info

Bond use simple core CPU
bobololo use dual core CPU perhaps simple SMTP optimisation for Nero Decoder ... ???

As you can see both ateme and coreavc didn't take a performance hit (barely a dent in decimal part) when you add the playback component in (since they are both single threaded, just like dsfilters and players) whereas nero took a nose dive since its multi-threaded performance was negated by necessity to wait for the single threaded dsfilters and players. I think the result of the comparison that bobololo made is that it doesn't matter if one step is multi-threaded, you gotta get all software in your playback chain multi-threaded, or you don't get benefit. Thanks for that bobo makes me feel better about not having dual core just yet.
