@Casimir666

ok; redownloaded 528_debug.

vmr9renderless, reclock, and internal MPCHC decoder.
video properly bitstreams, audio properly bitstreams.

video play right off the bat.

seeking works (however somewhat slowly...nothing crazy though)

framerate is below 10 F.P.S. constantly.

movie used:
The.Bridge.on.the.River.Kwai.1957.720p.HDTV.x264-CtrlHD

i get the normal framerate with the 528_debug version, if i close my antivirusprogram it will play the smoothly

That cannot be since I'm using EVR Custom to make DXVA work. And it seems that the resizing options only affects the video itself, not the subs. Just tested it. I can only think about the subtitle engine. Now that I look at it it seems that the subs have anti-aliasing applied to them, just that it's too much for my tastes. MPC already makes the shadows and borders of the subs larger and the letters are smaller than VSFilter, plus the anti-aliasing makes them look blurred. What do you think? Two more examples, in the first pic as the subs are larger the effect is much less noticeable, but it's there:



With VSFilter:

I tried that and it did not help.

When I change from Quicktime to Directshow for .mov, it doesn't even know that is an ADPCM:

Go to your graphic card control panel applet and turn off all anti-aliasing options you can find. Easier to do with nVidia card than ATI.

Did you use different resizing methods or renderers when making those screenshots?

@Stargazer: Go in MPC Options -> Subtitles node and set Maximum texture resolution to desktop.

I can confirm that using the internal subtitle engine the subs appear "little blurred" no matter what. With the external VsFilter the subs appear regularly sharp.

But this behavouring is present from the dawn of MPC. Indeed never understood why. No resizer, no antialias, no.... but subs always blurred. (Pheraps it's related with the fact that being sent directly in the video they are sent as YUV/YV12 so they lost the preciseness 'cause not in RGB colorspace?)

528_debug version work fine on XP-DXVA1, normal framerate, seek work - but if antivirus(KIS 7) is disabled, and cpu load is more than non debug 528 version on Vista-DXVA2 - 30-40% on C2D@3.2 ... possible because is debug version.

http://www.zshare.net/download/127369352f5f7b87/ - also as older version black screen on XP.

Test on sample there ref_num>4.

That's because VSFilter "prints" subs into the image, and when you have a SD source the subs are in the same resolution of that video. If it's 640x480 for example, the subs will be impressed inside those 640x480 pixels, and the resized, that's why in that concrete video VSFilter is way more blurred, simply the way it works. Now go and grab some videos @720p if your monitor is 1280x1024 (no resize needed). You'll find that VSFilter gives you simply perfect (and antialiased) subs, and MPC will look blurry. Also notice that in those pics even if they are blurred or not, shadows are different, and font size too.

Texture resolution makes no difference. AA is disabled, but it also makes no difference. All resizing methods and renderers have the same effect. In my caps all is the same except subs being rendered by MPC or VSFilter. Remember I'm using EVR Custom + DXVA (for MPC subs) and EVR Custom + VSFilter (no DXVA), running Vista64 SP1 and an ATI HD3870.

Also exist the "problem" that MPC uses different font, border and shadow sizes. I suppose this is mainly due to the way MPC renders the subs, but it's not only that. ASS files with different borders and shadows look like the autor wants with VSFilter, but not in MPC. They look the same except changing colors only, not the entire style.

I'd love to see something like an internal VSFilter, rendering the subs the same as VSFilter but not putting them into the image, allowing DXVA with VSFilter styled subs. Something like putting VSFilter before the video codec in Graphedit. That would be sweet if the MPC developers can do it.

If you want I can upload some samples with different subs that will show you exactly what I'm talking about

[3ngel]

I was wondering.
It would be possible to add a Colospace Selector to the internal VC1 (and Mpeg2) Decoder in order to wipe away definetively all the issues regarding YUV->RGB (16/0) luma issue?

With a selected RGB32 the conversion would be done directly from the player so the color chain would be consistent no matter what Graphic Card.

Moreover, any news on the VC-1 interlaced issue?

Thanks

The Haali Renderer output really improved playback for me. These recent test builds have made video tear up like crazy under VMR9 but since I finally decided to use the Haali Renderer, playback has been as smooth as butter and my subtitles work flawlessly. Looks like I'm never going back to VMR output ever again.

I know how both vsfilter and the internal MPC subtitle engine works. What I want to ask you is why the girl and the man looks sharper in the picture with MPC subs compared to what the one in VSFilter sub picture. I'm not comparing subtitles sharpness in any way.

Sorry, I misunderstand you. Anyway, I hope anyone of the MPC could look into this too Now your answer:

When using DXVA and SD videos, the IQ enhancements of the ATI kicks in. What you're noticing is Edge-enhancement, a value of 35 in CCC. That gives me the best results, more will turn the image into shit. But this doesn't work for HD, that's why you don't see any difference between the other two pics, and the ones here. There in the Gundam Wing ones EE is making a very good job too.

Hmmm... from my tests, even without DXVA the IQ can still be usable on all kind of videos as long as it was SD resolution. Can't make it to be used with HD videos though.

BTW, the subtitle engine in MPC-HC used VSFilter codes already, so I do not think your request can be granted. The only difference with external is probably the need of a Direct3D video card by the internal engine in MPC. Isn't clsid the one who wrote the code for this? Maybe you should just ask him.

[Liisachan]

@STaRGaZeR: have you ever tried 'ScaledBorderAndShadow: Yes' in ASS? (e.g. the border should be 200% in size if the picture/text size is 200%). Sorry OT.

[xW0Lf]

hmmm
one question:
if dedicated chip for h.264 decoding in ati 2x00HD and newer (nvidia 8x00 cards too) can decode only standard h.264 files on-the-fly (example: 1080p with <=4 ref. frames)...
can we do something to avoid that limitation and still use some of graphic-card features to off-load main CPU?
like as decode only parts of h.264 stream, not full (50% work to decode using cpu and 50% to decode using GPU)...
or to use shaders to decode h.264 in GPU ...

main goal is to send part of job to GPU....
i still have single-core P4 @ 3.4ghz and sometimes, when playing 1080P streams (full 1920x1080 with picture, without croping black regions), i got some frame drops/skiping...
and... most of my 1080p collection is non-standard (>4 ref.frames)....

so?
any ideas?

OP links to this work in progress thread. The answer is "yes, but not by MPC any time soon"

[burfadel]

When you use frame by frame seek by pressing the right cursor key, when you press play again the sound plays from the initial position to where you finished going frame by frame before the picture starts off again. The sound should play directly from where the last frame is seeked! Also a left frame by frame seek would be good,

the same for a non problematic apple trailer would be good too.

sorry for the late reply
here is the log of the mkv sample and the apple trailer that had problems, i also included 2 720p spider-man 3 trailers that seems to not have problems
http://rapidshare.com/files/11865151...pc_hc.zip.html

note: i actually noticed that even some of the 720p and 480p HD apple trailers that i thought at the beginning worked perfectly, turned out to have a problematic frame somewhere, i noticed this with Wanted trailer (frame: 3169)

but surprisingly i didn't notice this with the 1080p trailers, for example i have problems with the 480p and 720p HD trailer of the diary of the dead, but i didn't have a problem with the 1080p version !

link for the mkv sample that had a problem: http://rapidshare.com/files/118143839/sample.mkv.html (5.50 MB)
link for spider-man 3 720p trailers: http://www.jurassicpunk.com/movies/spiderman3.shtml (i used the "trailer" and "final trailers, "teaser" had a problem)

the video could be corrupted, but when i disable the the DXVA or play the sample with vlc player, the artefacts doesn't show

without DXVA:

i tested the sample with r527 / vista sp1 x32 / nvidia 8600GT
