DiAVC decoder, yet another fast H.264 high profile decoder

3) There are free DXVA players/codecs (PotPlayer, MPC-HC, FFDShow DXVA) plus WMP12 for Windows 7

Well, I answer your question before you ask so see last post, short answer is "DGAVCDecDi".

[NikosD]

The cheating goes more to All-in-one players, not the customizable codecs.

Yeah, I saw it after my post

[Fadeout]

If you are close to the limit DiAVC buys you some more space because it's faster. Same reasons for buying CoreAVC.

For a number of systems they make the difference.

Soooooo about that Windows 7 64bit bug...

[schweinsz]

I uploaded a new version of the DiAVC Trial version to di-avc.com. Please download it and use it on win7 x64, perhaps it works.

It does indeed work.

[Guest]

Congratulations, schweinsz, and thank you.

[sneaker_ger]

Yes, I did a very short test and it seems to work indeed.

[NikosD]

Yes, it works.

And yes it's the slowest.

System:
Win 7 x64 - C2D@2.83GHz

Sample Test:
http://rapidshare.com/files/41658614...7Mbps.mov.html

Using graphstudio (3 passes) average results:

CoreAVC v2.0
Work time: 00:00:07:656 107.8842 fps
FFMpeg-mt rev 3563
Work time: 00:00:08203 100.6872 fps
DiAVC v1.2.0.7
Work time 00:00:08.316 99.3296 fps

Third out of three for the "World's Fastest H.264 High-Definition Software Decoder"

This is movie trailer that are all coded using the CAVLC. But most of the movies available are coded by CABAC. You should test the decoders using more bitstreams.

It's faster on everything I've tested so far.
Using dss2 and avs2avi (-o n -c null) on the rat.264 file (muxed to mkv) in the dg benchmark thread (this is on an i7@3.8ghz):

ffmpeg-mt: ~209fps
diavc: ~270fps

And I'm fairly certain people would mainly use this for cabac decoding, which it should (and appears to) be the fastest in the vast majority of cases.

OK, let's play by your rules.

New clip. A CABAC one this time.

DiAVC is still the slowest

CoreAVC
Work time: 00:00:24.987 102.8126 fps
FFMpeg-mt
Work time: 00:00:25.445 100.9624 fps
DiAVC
Work time: 00:00:26.441 97.1589 fps

Third out of three.

It makes me wonder what will be your next excuse to justify the "World's Fastest H.264 High-Definition Software Decoder" title

OK let's be honest to each other and the others.
Change the title to something more decent and modest for your potential customers.

[Disabled]

How are you measuring the performance? There are wrong ways to measure this you know? (I'd never thing I'd bring the CoreAVC excuse here...)
I have a similar system and DiAVC always was the fastest for me...
Those are all 32Bit codecs?

[madshi]

@NikosD, I don't see you complaining in the CoreAVC thread. They also claim to have the fastest software decoder. Why are you only complaining in this thread and not in the CoreAVC thread? Do you actually think that your benchmarks are the only ones that count and that all benchmarks done by other users are worthless? It seems that many people report that DiAVC is fastest for them. You seem to have better results with CoreAVC. That's fine, but if you want to complain, at least be fair and complain in both threads.

[Underground78]

DiAVC is clearly not optimized for CAVLC (but maybe schweinsz can do something for this ?) but I have different results than yours for your CABAC sample :
FFMpeg-mt : 80.8 fps
DivX H264 Decoder : 99.0 fps
CoreAVC : 105.9 fps
DiAVC : 109.5 fps

(Tested on Windows XP SP3 with an Athlon X2 6000+)

Edit : on my laptop :

CoreAVC (cuda) : 63.0 fps
FFMpeg-mt : 83.5 fps
CoreAVC : 86.5 fps
DiAVC : 104.8 fps

Don't know why CoreAVC is so slow here.

Complain with others results ?

This is the best advice I have heard for a long time.

I have aleady said that FFMpeg-mt, DivX, CoreAVC and now after my tests, DiAVC are very close in terms of performance generally.
There is no clear winner.
It depends on the clip and the CPU architecture.

My advice:
Use free software decoders like FFMpeg-mt and free DXVA decoders like FFDShow DXVA, MPC-HC, PotPlayer

@Superb and Mixer73
Where are you hiding ?

In that case neither DiAVC nor CoreAVC should claim to have the fastest decoder, right? So again: Why do you complain about DiAVC's claim, and why do you not complain about CoreAVC's similar claim?

Are you aware that it is quite rude to enter a thread and then post "my advice is to use something else"?

Anyway, you've posted your opinion, you've posted your advice, so maybe now it's time for you to move on and leave this thread be. Thank you.

[Underground78]

@schweinsz : are you aware that DiAVC can play Lossless H264 files created using x264 ?

I gave advice because you gave advice. Complain to another thread etc etc

To your next advice I reply that I have no intention to close this thread. Nor the power to close it, even if you seem to give me such power.

And I can write to every thread I want, whenever I want.

Keep these kind of advices to yourself and others.

Thank you
