I'm trying to use madVR with BSPlayer with I can't get it to work, it never shows up the video... do I need to do anything special? It works fine with MPC-HC with no extra configuration...

That's a question you should probably ask the BSPlayer developer(s). Most people here use different media players, so there's not much experience here that could help you...

So it might be the same for you, I already notified nevcariel about it.
Yes I use Lav, not haali. Would you recommend I increase my CPU queue to a higher number than default? Same with the GPU queue?

Here is a screenshot taken the exact moment of a delayed frame. I don't get any dropped frames during playback at all (the dropped frames in this screenshot are from initally booting the video up). As you can see none of the queues seem to drop when this occurs, so i'm stumped.

Delayed frames can occur during windowed playback. Of course ideally they shouldn't, but they sometimes do. If you want to avoid this, try using fullscreen exclusive mode.

Ah so it's not necessarily a problem with playback, my GPU or anything, just something that happens? Is there any way to get rid of them at all?

I posted a problem I seem to have with FEM not so long ago but it seemed to have been overlooked, in that when i switch to exclusive mode my average rendering time seems to go through the roof. From my understanding when in exclusive mode the video works directly from the GPU, so you should receive much better playback, so I have no idea why it seems worse when i switch to it. I have left all exclusive mode settings as default in the madVR settings, could this be why?

I apologise for all the questions as well!

Hi guys,
a pair of questions:
I am sending video to my 720p plasma and am wondering whether I should set its resolution to 50 or 60hz when using smooth motion FRC?
What are advantages of using "separate device for presentation" on Intel HD3000?
Thanks for replies, and godspeed our video emperor Madshi!

madshi said that the higher the better as FRC simulates an infinite refresh rate. So if I were you I'd try to reach as high as you can get, some displays can reach up to 72Hz(and 120Hz if 3D capable) FWIW...even a bit over 60Hz wouldn't hurt

So does the above issue only affect XySubFilter.dll and NOT VSFilter.dll? (If I'm not updating to 0.86.2)

It sounds like you want "none" to me. This is what I use as well, all the other options use the GPU. The "hardware" doing the acceleration is on the GPU.

RGB Output Levels:
Untouched, leave converting color spaces to MadVR.

Dithering Mode:
Random unless you plan to re-encode the output. Random is visually higher quality but it does not encode as well.

You can turn on Yadif in LAV for software deinterlacing, I use video mode for real interlaced video (30i in my case).

All you need to do in LAV to keep the GPU free is to use "none" for hardware acceleration and don't use any shader scripts in MPC-HC.
thanks a lot asmodian!
though i would have loved to hear madshi's thoughts as well as i do see him replying to new users of madvr... no matter how simple the question. a bit disappointed.

i understand what u r saying regarding LAV filters. thank u.
btw, what is "shader scripts in MPC-HC?" & how do i avoid them?

now that u have explained to me how i can get the LAV filters powered by the CPU only, how do i get madVR working with the Nvidia Gpu exclusively?
because i mean like how do i know that madvr is instead being powered by the intel integrated graphics?

thanks a lot!

question about the second smooth motion option- "or if the display refresh rate is an exact multiple of the movie refresh rate"
what is the difference between this and the always on option?
cause doesn't the second option cover every possibility?

VSFilter.dll draw subtitles onto video frame before it reaches madVR. madVR doesn't even know that subtitles were drown. And sure 3DLUT is applied to whole frame (with subs). With XySubFilter.dll it works quite differently, so yes only XySubFilter.dll was affected.

I was testing XySubFilter.dll and I really like it especially for PGS subtitles. http://screenshotcomparison.com/comparison/27166/ (#3 are HD subtitles that's why quality is similar, but we can see that ISR render at wrong levels it seems)

I have issue with blinking video frame when subtitle appear and DXVA deinterlacing is enabled. Reported it already on trac. I wonder why no one spots this bug before.

I got a problem after updating these today:

-Ati drivers
-MPC-HC
-Lav filters
-madVR

I guess all of the versions were from 6 months to 12 months old.

The problem is that mpc-hc won't close properly, the process i still running, preventing running new video files. I tried to search, and some people points at madVR. When I use an another renderer (EVR custom pres), the problem dissappears. Any idea?

At first thx for your help and you madvr.
I tried to take a screenshot but if I stop the movie seem that artifacts disappear. It's something related to motion in the frames.

I'll try to explain, imagine a panning quite fast scene, around the edge\border of a character I can see artifacts, something that similar to ringing artifacts.

Another typical scene for this issue is a panning frame with a wire mesh, the border of the mesh shows artifacts.

By the way I'm a real noob (with HQ love) and maybe is not a madvr fault but if you have some tips i'll be thankfull!!!

i used to have that issue it is a mpc-hc bug, it has been fixed in the nightlies

Yes, this was a bug in prior version of madVR with XySubFilter.dll (not yet released). This is why I asked madshi to update the changelog, since these bugs which were fixed have nothing to do with xy-VSFilter (VSFilter.dll). It looks as though the changelog in the first post of the thread wasn't updated yet.

We are aware of this issue with black boxes and/or flashing between lines with bitmap subtitles (PGS/DVB/VOBSUB). I can occasionally reproduce it with progressive content as well. At this point in time we believe this is caused by a performance issue in XySubFilter which results in sending a bogus bitmap to madVR, and something on our to-do list before we move on to user testing and a beta release. Only bugs which we believe were caused by madVR were added to madshi's bug tracker, all bugs we believe are caused by XySubFilter specifically we are tracking privately internally.

Maybe were missing a bit of logging around this area, since I not seeing anything that madVR is requesting yuvMatrix for every frame. All I see is that XySubFilter updates the yuvMatrix once immediately after the resolution rectangle change, and immediately after start sending new bitmaps and positions to madVR. I do agree that XySubFilter shouldn't be getting stuck on a yuvMatrix request if that's really what's occurring, I also believe that requesting yuvMatrix for every frame is a bit overkill especially if you wanted to mimic xy-VSFilter which at this point in time doesn't support changing yuvMatrix mid-stream at all, except video user override in the settings GUI. Maybe this should be changed so its the responsibility of the subtitle provider to inform the subtitle consumer of the yuvMatrix only when something may have changed. It seems possible considering our logging, that this is what XySubFilter is already doing, but I don't really know.

Could you clarify this once more.

Theoretically if a subtitle provider only updates yuvMatrix once at the beginning of the stream and ignores all further yuvMatrix requests from the subtitle consumer, but continues to respond to RequestFrame & GetBitmap requests nominally, what is the intended behavior by madVR? Assuming our logs are accurate, XySubFilter does not seem to be stuck internally, since immediately after the resolution change and updating yuvMatrix, we start responding to all RequestFrame & GetBitmap requests.

What requirements need to be met in madVR internally before it renders subtitles from the subtitle queue?

Okay. After I confirm with the developer what's going on I'll email you. He has not yet tested madVR 0.86.2 with this behavior change yet, so there could be an oversight somewhere. Overall, GetOutputRect sounds a bit more likely as a cause of stalling rather than yuvMatrix.

Oh, I see. So I should not post it on bug tracker. But I did it already so if you like you can comment and clarify that this is NOT madVR bug so madshi can close the ticket.

By the way this public repo is the most recent?

No, we've recently only been occasionally merging changes there. The most up-to-date development commits usually end up on one of the xy_sub_filter branches of my GitHub repository. Just be aware that at this point in time we give no guarantees that any given commit will actually build successfully or not contain a new critical bug. Our process usually goes, commit a bunch of experimental changes and/or bug-fixes, test, commit fixes via force push which wipes out and replaces a bunch of older commits. Before you build anything, you should always do a pull and hard reset to ensure you have the latest versions of commits.

Overall neither our XySubFilter or xy-VSFilter development branches, including the one on repo.or.cz, do we consider suitable for user testing, since at any given time they could be in an unstable state of flux. As a rule of thumb, we release new binaries on GoogleCode whenever our codebase is stable without any critical issues. If we haven't released anything, it doesn't mean we are holding back changes, but rather there is a critical bug, regression, or unfinished feature which we don't want to expose end-users to. This applies to both xy-VSFilter and XySubFilter, so just keep this in mind whenever testing unreleased code.

I'm using XP x64 with MPC-HC x86 last build from xhmikosr + Haali splitter + madVR last build + 9600GT @301.42 driver and getting this:



Any idea?
