[Aleksoid1978]

I guess since updating to a newer graphics driver DXVA playback produces artifacts. Using the non-DXVA internal filters the video is fine. It looks like this:

System OS is Windows 7 x64, MPC-HC build 1.3.1249.0, graphics card is an AMD Radeon 4870, graphics driver version is 10.4. Output settings is EVR+custom.

PS: Just checked and used ffdshow for decoding with hardware acceleration enabled. Same artifacts. So it's a driver issue. Probably not MPC-HC's fault.

PS2: reverted back to driver version 10.3. artifacts gone.

Aaah. btw, right now seeking with ffdshow+hw shows the same artifacts for a split second. so the bug in 10.4 seems to be that the driver is ignoring I-frames or so constantly...
This is issue with 10.4 driver. You can download last version MPC-HC and set Disable DXVA for SD in video decoder Properties.

Nijiko: MPC-HC is always looking for more volunteers to work on and help improve code.

People work on parts that they are interested in.

Yes. I see.
So I don't grumble about MPC-HC.
I just hope MPC-HC will make better.
Gabest's MPC is a mythology.

[namaiki]

It seems that you see something that others do not.
By reading the source of MPC-HC, there is a big problem with whole frame of MPC-HC.

Perhaps you could try some experiementation on code yourself.

The internal x264 decoder must be buggy or something, cause I get lots of broken "squares" on the screen (not all time time, but every few seconds. Sorry I cannot find better words to describe it :) When I unchecked H264 DXVA in options and let FFDShow handle it, it was all good.

[namaiki]

Octo-puss" What is your GPU, what version of windows and what graphics drivers?

You know, they say an image is worth a thousand words. Post up a link to a screenshot on imageshack.us or other.

Create a new ticket (http://sourceforge.net/apps/trac/mpc-hc/report) and provide a sample and your system's specifications.

Octo-puss, just curious but what happens if you use the Microsoft DTV-DVD Video Decoding filter instead of the MPC Video Decoder (set as prefer in external filters)

Oh hell! Did you even read the last posts?

It's the graphics card driver, revert to 10.3. DXVA is broken in the driver, no matter what decoder you use. You obviously have hardware acceleration disabled in ffdshow.

Booji Boy@
Are you sure ? PDVD10 h.264 (DXVA on) + CAT. 10.4 and no problem at all.

As discussed on previous page, with 10.4 broken DXVA for SD video, and as workaround in mpc hc added corresponding checkbox.
If only people read topic before posting...

Of course i read it.
I posted SD video sample few pages here. This sample is blocky under MPC-HC but working fine if PDVD10 decoder is in use like before. This pointing the problem is in MPC/FFDshow DXVA decoder.

Sorry, I am just a green-hand in this field.
Though some algorithm I don't agree with, I have no better ideas...
For example, trying using with all kinds of different filters, there are some problems happening with MPC-HC, but not with MPC or WMP.
Some developer of MPC-HC said it's not the problem with MPC-HC, instead of the 3rd party filter, but I don't think so.
I mainly found the problems by playing experience.

They talk abou the SVN version: http://xvidvideo.ru/

The last is 1834.

No I did not, I really don't have time to read tens of posts everyday to check whether something was discussed x pages ago, sorry. Just wanted to report something that looked like a bug to me.
And I don't even know FFD supports hw acceleration.

[Fadeout]

I'm having some problems and I need someone to explain me how things work.

I'm using SVN 1834 on W7 and latest ATI drivers, so with DXVA enabled. Today I noticed that the video got heavy stutters in the end credits. Statistics show it's dropping a lot of frames and this happen only with subtitles on (but they do not seem animated). CPU usage is low.

I tried different settings for the subs, but the heavy stutter is always there.

Then I tried to change from EVR Custom Pres to EVR Synch: stutter gone, frames not dropped.

What's up with this? I'm tempted to keep EVR Synch by default since it seems working, but what's the difference? What are the downsides of one or the other?

EDIT: EVR Synch is not better, it only hides the problem since there's still stuttering but more distributed between frames, so less noticeable. Statistics show a crazy number of synch glitches with EVR Synch (so bad synch but no dropped frames), whereas the other mode dumps entire blocks of frames (and stays in synch).

I guess this problem is unsolvable at this time. I should also point out again that the "bug" is in the handling of subtitles since it's the appearance of subs that screws the output and gives these synch problems.

Ok so I bought the ArcSoft DTS Decoder but I don't know how to use it to decode DTS-HD MA tracks with MPC. Anyone know?

[mark0077]

Guys, are index.bdmv files supposed to play in mpc-hc. I have copied one of my new blu-rays to disk (Avatar). I have two problems.

1) index.bdmv won't play in mpc-hc, just nothing happens. I can play manually by opening one of the m2ts files though. Is opening index.bdmv supposed to be possible?
- If not, how could I open a bdmv directory through the command line?
2) An unrelated problem I will need to look elsewhere for a solution, basically xbmc isn't recognizing the Avatar/BDMV/ directory as a movie.
- Does anyone know how to make xbmc read blu-rays, in a way that will allow it to open then in mpc-hc (ie not by the index.bdmv file if not supported).

[Darth Viorel]

Of course i read it.
I posted SD video sample few pages here. This sample is blocky under MPC-HC but working fine if PDVD10 decoder is in use like before. This pointing the problem is in MPC/FFDshow DXVA decoder.

I can confirm that. Some SD videos with more than 8 ref frames are blocky with the MPC and ffdshow dxva decoder but work with the PDVD10 one.

[sabret00the]

Just noticed a bunch of GUI bugs had their milestone (1.4) removed, why?

http://sourceforge.net/apps/trac/mpc-hc/ticket/366
http://sourceforge.net/apps/trac/mpc-hc/ticket/367
http://sourceforge.net/apps/trac/mpc-hc/ticket/368

[tetsuo55]

Those three tickets are feature requests that we are not going to be actively working on any time soon (if ever).
So their milestone has been changed to someday-maybe

[Booji Boy]

I can confirm that. Some SD videos with more than 8 ref frames are blocky with the MPC and ffdshow dxva decoder but work with the PDVD10 one.
As ATI's driver does full bitstream decoding with the most recent gfx cards, maybe the PDVD10 does not make use of DXVA for SD videos?

[Darth Viorel]

MPC shows dxva in the lower left corner and the clocks of the card (HD 5770) are 400/900 MHz so I think dxva is used.

[neoufo51]

I'm getting LOTS of video stuttering on the latest (1834) build of MPC-HC. Win7 on an Nvidia GS8400 card, 195.62 drivers.

There are some problems(?) with opening video clip files.
Setting has been set to auto-zoom 100%, but sometime opening window is smaller than 100%.
After press ALT-2 (set to 100%), window will enlarge.
I don't know whether it's a problem.

[cicciociccio2]

Sorry for my bad english...

I found a problem with MPC-HC 1820-> with Radeon 3650 and driver 10.4.
In this version the "limiter" L4.1 for DXVA decoding with ati vendor was moved to L5.1.
Unfortunately, only the Ati 4xxx and 5xxx and 3200IGP (UVD2 compatible) really support L5.1 though not present in the change log.

Then MPC-HC not skip DXVA mode in L5.1 video to software render....the result is full of artifacts... :(

Is possible including in the next version of MPC-HC a manual or automatic limitier to L4.1 for Ati 2xxx and 3xxx?
Thanx to all ;)

[mark0077]

I figured out why index.bdmv files wern't working for me. Its because mpc-hc can't seem to play them if they don't exist within a folder called BDMV. Can this be tweaked to work without the BDMV folder name?

MPC should work out-of-the-box for everyone. So detection of the UVD version should be done if possible. If not, then L5.1 support for ATI cards should be made optional (and disabled by default).

Is the amount of dedicated memory of the card relevant? If so, that should be factored in the DXVA decision making algorithm as well.

My 3650 has 256Mb of Vram.
I tried the same video (L5.1) on Ati Radeon 4350 256Mb with same driver version (10.4) and it works perfectly.
DXVA is correctly enabled.

ATI should be more precise in the change log of driver release... :rolleyes:

PS
Tnx for the great job ;)

Hi,

since i switched to an ati 5970 the mpc dxva video decoder gives me RANDOM screen corruption when playing HD videos.

When playing the same HD videos with the cyberlink h.264 decoder (PDVD8) in DXVA mode i get no corruption at all.

This happens with Catalyst 10.3 and 10.4a.

Tried all combinations of Flush..., Desktop composition and tried even 15 Frames buffer in custom presenter evr mode.

So the conclusion of this is, that something is not right with the mpc dxva videodecoder as cyberlinks decoder (PDVD8) works without a problem.

And i double checked that the cyberlink decoder is realy in DXVA Mode.

Hi,

I've been trying to enable DXVA for some time already. I've followed every MPC-HC tutorial, downloaded every sample movie there is but no luck.

I'm running Win XP SP3,
My card is GF 9600GT Silent with newest drivers (older obnes don't work either)

What leads you to believe that DXVA isn't working? How have you configured MPC HC to use DXVA? It's odd that it isn't working for you. It works for everyone else with ease (present ATI H.264 L 5.1 issues excluded). While you have provided a good deal of information there is nothing about your configuration or any detailed symptoms.

[Keiyakusha]

Tell me please why subtitle text size is changing when I have SRT subtitles and selecting/deselecting option Play -> Subtitles -> Default style? As I understand this option is for overriding any styles with default one which is defined in settings. But SRT doesn't have any styles so this option shouldn't have any effect?

In MPC-HC, View-> Options-> output-> make sure that output is VMR9(renderless), under playback make sure that auto-load subtitles is ticked, under internal filters, make sure that h264/avc(dxva) is ticked.

the above should work for most people. if it does not, first post media info of a file you are playing, then list everything under the menu 'play-> filters' when playing that file. please note that divx/xvid files cannot be accelerated.

That is one of the best things anybody on XP and Vista can do to resolve their playback issues.

[edigee]

@huskalr:

Be careful not to have an external subtitle filter loaded(ex DirectVobSub), otherwise the DXVA doesen't work. Use only internal MPC_HC subtitle filter. If you'll follow namaiki's advice DXVA should work with no problem.

Edit: Take a look here too;

Honestly, as an owner of a Vista and a 7 machine, this is crap.

7 is a nicer platform for Media Center for example (you need less things installed), but for a main-use machine I would struggle to find a specific benefit of 7 over Vista that isn't purely cosmetic in nature.

[nevcairiel]

Like, 7 is actually fast, while Vista is constantly crawling?
The vastly improved pre-fetching and memory-caching?
The improved DWM and Aero, that actually improve video playback?
Lower overall resource usage (maybe short of HDD space)?
The vastly improved CPU scheduler for multi-core systems?
The not-annoying UAC (granted you might call that "cosmetic")?

Granted, some of these features were back-ported with the Vista Platform Update, but shrug, thats basically 7 tech.

I guess i could find more points, but shrug. 95% of the people i know that switched from Vista to 7 were stunned by the improvements, and very good out-of-the-box experience. But hey, YMMV. But whats the advantage sticking with Vista? :)

But seriously, if you use XP, switch already. EVR and Aero will give you much better playback.

Sorry for joining the Off-Topic posts, lets all get back to MPC-HC now.. =)

(a friend of mine said that W7 is kinda Vista for lazy people)
There might be some benefits ,but not for HD playback.

Edit: I'm from the 5%. Switched back to vista after a day with W7 only. Was stunned too.

[madshi]

A question to the devs:

I'm considering adding a subtitle input put to madVR, so that MPC HC's internal subtitle renderer can work with madVR. But I've no idea what kind of data such a pin would receive. Can somebody give me a rough description of what kind of pin the MPC HC subtitle renderer needs in a renderer?

Thanks!

[boyumeow]

littleD is right, something like

[um3k]

Would it be possible to set up specific filter chains for different file types/codecs? For instance, I want my HDV m2t files to decode with DScaler 5 and render with Haali, but I want HD H.264 to render with VMR9 so I can use DXVA.

[stax76]

MPC-HC lacks high DPI awareness (http://www.google.de/search?hl=de&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&q=windows+7+high+dpi&btnG=Suche&aq=f&aqi=&aql=&oq=&gs_rfai=), there is a very good video on channel9 (http://channel9.msdn.com/posts/yochay/Windows-7-Graphics--High-DPI/) explaining why is it important and how to implement it.

Overall performance, especially on slower PCs, is noticably better on Win7 than on Vista.
