madVR - high quality video renderer (GPU assisted)

[pie1394]

With madVR 0.27 , the FS and Window mode switching works a lot faster than it under 0.26. It is especially very obvious on my machine under WinXP x64 + 7300GT.

With 0.26, I got random Win7 frozen with some video clips under pausing. They are not easily to be duplicated. Hope such issue will never happen to 0.27 again.

For one particular AVI file encoded with MPEG4 (704x544 25fps) + AC-3 (448Kbps 4ch), if it is played with MPC-HC + Xvid 1.2 decoder + ACM decoder + madVR 0.26/0.27 at 1400x1050 60Hz monitor, the video is frozen and displayed around 10 seconds later. If the video rednerer is changed to VMR9 , it works fine. Very weird...

Maybe it is due to different muxing method, which makes madVR AV sync mechanism does not quickly response?

Madshi I have a few debug Logs I can send on if useful showing some periods of frame drops at the start of movies. This evening I watched Hannibal and at the end of the movie I had just 1 delayed frame but 179 frame drops most of which were noticeable. The log was almost 2gb though so I'll just send on the smaller ones.

[Thunderbolt8]

maybe you got so many dropped frames because your computer was busy creating that 2gb log :>

[mark0077]

maybe. But 2 gig file in 2 hours when. My hdd can write 2g in 17 seconds doesn't really add up to "busy". I doubt that causes such a slowdown in hdd reads to cause frame drops. The log is being written to c drive anyways and movie was on f drive. CPU usage is in low 2-3 percent even on max hdd reads.

Mostly in the middle of the video...but it just was jittering or tearing constantly, but when I disable exclusive mode it went away. The problem may be because I am using a beta version of MPC-HC http://www.xvidvideo.ru/media-player...inema-x86-x64/


Another problem:
Whenever I go to the MadVR properties to change a setting (i.e. Exclusive mode), the properties window is so long that I can't even hit the apply/ok button, even when I minimize my taskbar @ 1024 X 768. I have to temporarily raise the monitor resolution just so I can see the apply/ok button.

Just to be sure, does the full-screen exclusive mode only enable better playback performance?
Or, does it improve image quality also

thanks, madshi

Bugs/problems:

1. One of the following, depending on what your intentions were:
a) When seekbar is enabled, but automatic exclusive mode is disabled, the seekbar is still enabled in "normal" fullscreen.
b) The seekbar box is grayed out and can't be altered when auto-ex-mode is disabled.

2. You remember the shifted chroma plane issues with non-mod16 videos way back? I'm having those again when exiting exclusive mode.

3. Exiting exclusive mode is slow. Video will go black and pause for a second.

4. If you go from exclusive mode to windowed and then close the player, the screen will go black for a split second exactly when the player disappears from task manager.

Hi madshi excellent renderer, but is it possible to get exclusive mode to work on a secondary display?

I'm using mpc auto change, when i go full screen my second display stays blank while exclusive plays on my primary display. But when I put my mouse cursor on the second display it shows the video but says in window mode then goes blank after a couple seconds. I also can't get the madvr seekbar to show up.

My spec: Ati 5850, windows 7 64-bit, ffdshow, coreavc.

Thanks!

You have to make sure the player is on the 2nd display before open the file. I have similar setup and madVR works great.

Wow it works! Thanks alot!

It is the interlaced res that does it.

The stock Windows 1080i (29hz = what most would refer to as "1080i 60hz"), no Powerstrip, doesn't work either.


Thanks

madshi, one more bit of information that may (or may not) be useful.

With interlaced res's and powerstrip, you cannot use powerstrip to do the initial swap from a progressive res to an interlaced res.

You must set the PC/graphics driver to "interlaced mode" by setting either the Windows graphics settings OR ATi CCC to a stock interlaced res first.

After that is set, you can then tweak it in Powerstrip.


If I try and set an interlaced res directly in Powerstrip, you get this weird effect where you only see the top half of the screen.


I'm not sure it will affect what you are doing, it's just a quirk.

That might explain why 0.12 was not affected...

This is exactly right, DirectVobSub was set to upscale always and this was the cause of the problem. Changed it and it's now working well, cheers.

I'm not sure. Does your "Yes" answer my question? Do you have the seekbar enabled in the madVR options?

Ok. I think in a future madVR version I will be able to make exclusive mode work with interlaced in Vista and Windows 7. Not sure about XP.

Glad to hear that!

Really? Not sure why that is the case, but I won't complain, of course.

Can you shorten that AVI file to a small sample, with which the problem can still be reproduced? If so, you can upload that and I'll have a look.

At the *start* of movies? How do you define "start"? First 3 seconds? Or a longer time frame? Is this with v0.26 or does it still occur with v0.27? FWIW, I was hoping that the new frame drop/delay logic in v0.27 would help madVR getting smooth quicker at the start of a movie, compared to v0.26.

Remind me, which is your hardware/software setup? Is v0.27 behaving better, worse or about equal compared to v0.26 for you? Is there any difference between windowed and exclusive mode for you? Do you also have those frame drops in exclusive mode?

Most of us are using MPC HC beta builds. That should not be the cause of the problem. As I said before, I think there's something wrong with your software installation. There's no way that fullscreen exclusive mode can tear with properly installed drivers and applications. I'd suggest reinstalling graphics drivers, media player and filters.

The image in exclusive mode is not sharper or more colorful, if you mean that.

Ah yes, you're right.

Only when exiting exlusive mode? That's very weird. I can't reproduce it here. Can you upload a sample once again? Which codec (h264, MPEG2, VC-1 etc) are we talking about? And which decoder are you using?

There's nothing I can do about that.

That's the way it is and I can't do anything about that, either. Or does this effect not occur when exiting the media player, after having used EVR fullscreen exclusive mode?

It's still all versions past 0.17, from what I have tested.
The thing is, sometimes the video is jumpy, but sometimes it looks perfect. Using High and Aero timings seems to lessen the effect when it occurs, but it is still there.

Yes, only after exiting exclusive mode, and it will get stuck there until I restart the player.

I can't reproduce it either. Which build of MPC-HC are you using?

Ah, that's with 24fps on 60Hz content, right? Will improve that later, but it doesn't have high priority right now.

I can't reproduce it. Tried on both my XPSP3 dev PC and on my win7 x64 HTPC. Can you please check pin connection info before and after the exclusive switch? Does the pin connection info change? Also a log might be helpful...

Yeah, it's still the same 24fps@60Hz thing. Sorry about that.

Hi there

I might have missed the obvious while trawling through the 200 odd pages but could anyone point me to info on how to install madvr from scratch (using say...MPC-HC as the player)? i.e. Do I JUST need MPC-HC and MadVR. Or do I need more?

I have the following setup:
- a ASUS N71 laptop (which has a Core I7-720 M CPU and 1 GB ATI 5730)
- I connect this with a HDMI v1.3c cable to a 50inch plasma (a Panasonic Viera NeoPDP S20, model no TX-P50S20B)
- I have Catayst 10.6 installed on Windows 7 (64bit)
- I had installed CCCP (Combined Community Codec Pack) and then installed MadVR. I then simply went into MPC-HC and changed output to MadVR
- my TV allows me to choose 23hz as a refresh rate so I've chosen that (which i think means 23.976)
- I've also read in the forums that its best to change the pixel format so I've changed from the default of "YCbCr 4:4:4" to "RGB 4:4:4: Pixel Format PC Standard (Full RGB)"

I mainly watch 720p/1080p x264 movies on the TV. Only thing is i'm not sure if the above way is the ideal way to using MadVR? With the above setup the playback is still not smooth so I fear I might not be installing things in the most efficient manner or simply have it configured incorrectly.

Appreciate any help....this thread btw is a great read! Oh and madshi, its impossible to go back to anything else now that I've seen madvr....thanks so much for your efforts thus far!
