yes i saw that the q6600 pc, i just thought you may have run those test on a different computer. is diavc stable in its image output? does it artifact at all or is it ok to use as a primary decoder even though its in alpha stage?

There are no visible artifacts in my test clip. However I didn't check whether the output is bit-identical to other decoders.

I verify all conformance clips in the H.264 official site. There do exists one problem with the DiAVC. When there are multi slices with different slice type (P slice and others) in one picture, the DiAVC has a deblock problem with BS=1, but it influence little (about within[-2,2]), and I believe there exist hardly this bitstream in the world.

Needless to say that any filters inside ffdshow should be disabled as well

When I finished some more important works (such as speed improment, feature supports, 64-bit and super-resolution for SD contents), I can work on it. If 64-bit is very complex, I perhaps work on support for old cpu.

I finally was able to get a windows computer to test this thing. Its a CoreDuo T2300 (1.66Ghz), WinXP SP3, 1 GB Ram, Intel GMAsomething. Benches were done using monograms GraphStudio benchmark, with 3-5 runs with null renderer. I also did comparisons with timecodec, while the numbers were a bit different, the trend was the same.
http://gamersyde.com/download_assass...-13631_en.html 720p, 60fps 10:52 minutes ffdshow: 124.3667 DivX: 166.9982 CoreAVC: 165.1547 DiAVC: 180.8032 ADST_sample posted earlier 1080p, 23.976fps, 1:31 minutes ffdshow: 40.2649 DivX: 54.5507 CoreAVC: 54.1513 DiAVC: 56.9768 ImperishableNightExtraStage.mp4 from DarkShikari 640x480, 60fps, 9:35 minutes ffdshow: 225.7021 DivX: 340.6914 CoreAVC: 345.6809 DiAVC: 312.1756 So nice performance for me, also no artifacts were visible for all samples. I have the impression that the decoder needs a second to startup, that might have decreased the performance, especially for the last test, as that run the fastest. |

Like Disabled, I noticed a startup delay when opening new videos. Hopefully this minor issue can be fixed. Another issue I noticed was that the filter is incompatible with DirectVobSub (VSFilter) if the video resolution is not mod16. The filter connects, but the video only shows a black frame (tested with MPC-HC/EVR Custom). Maybe this is a bug in DirectVobSub though.
On the bright side, I was able to measure the performance being consistently 10-15% higher than CoreAVC on my Core 2 Duo T7250. If the beta version can fix those issues and increase performance by 20% as schweinsz said, it will be perfect. |

EDIT: Yes with EVR-CP there is some problems with not showing subtitles, but the screen is not black for me. Will test some more too... Ohh, when I tested the speed, my results also showed that DiAVC is not that fast with small SD videos, but I never thought about startup delay... Need to run some more tests.

How do I get it working with Haali Renderer? It works with all other renderers but when I try use it with Haali Renderer, it automatically changes back to just "Video Renderer". I'm on 64bit XP Pro, using 32bit MPC HC.

OK, tested this thing a bit more. Yes I can confirm black screen but it shows picture if you do some seeking. What is wierd, if I do some seeking, close the player then when I open it - it works. If I close player and open again - black screen. This is what confused me... Last edited by Keiyakusha; 25th November 2009 at 18:21. |

I am talking about mod8 width, e.g. 712x480. I am also not talking about the internal subtitle renderer which works just fine but about the standalone DirectVobSub. It produces a black frame when the width is not mod16 and it is receiving input from DiAVC.

Yes. I understand this. By the way the post you quoted a bit outdated now. As I say I see black screen with mod8 height too, but it acts somewhat wierd. The sample I tested have some black frames at the beginning so at first I not noticed that player shows black screen and after seeking it starts to show normal image. Maybe i'll test mod8 width sometime later.

I did some tests with MPC-HC 1351 on windows 7 x64. mkv files everything is ok except the aforementioned slow seeking.
But there's some issues with m2ts files. Gabest MPEG splitter + DiAVC = double speed playback, crashes on seek Haali media splitter + DiAVC = playback ok, crashes on seek |
