Please try with v0.42, should be fixed now.

Please try v0.42, hopefully all problems should be fixed now.

Can you please make a new log with v0.42? I've added some new output information that might help figuring out what's going on.

Fixed in v0.42.

I don't really understand what you're saying. You're saying madVR goes into exclusive mode on the wrong monitor? Please make sure that you move the media player to the right monitor *before* you load the video file. If you load the video file first, and move the media player to the other monitor afterwards, you'll run into problems. That problem will be fixed in a future madVR version.

madVR v0.42 released

http://madshi.net/madVR.zip

* changed aspect ratio reporting back (PotPlayer and JR MC didn't like v0.41)
* improved forced redrawing of all GUI stuff after exclusive -> windowed switch
* removed some of the "disable desktop composition" modes

[ajp_anton]

When the Windows 7 magnifier is active (with or without magnification), the mouse arrow/hand isn't visible in exclusive mode.
(I sometimes use the magnification since I sit much farther away from the screen when watching movies, but need to navigate some menus.)

This also happens with other renderers that have an exclusive mode or similar, so not sure if there's anything you can do about it...

[Vovanchik]

move media player to the right monitor *before* you load the video file

Yes, it works. Thanks.

With this setting, move player *before* does not need

why in the exclusive GUI does not show the current time / remaining?

sorry for bad english

Wow that was quick .
Here's the new log.
I switched to FSE at about 10s again and back to windowed mode at roughly 20s.

If I recall correctly this is on madshi's todo list and will be implemented later on.

[leeperry]

for the new build!

the AR problem in PotP is solved, indeed

the zombie frames problem and the partially refreshed menus are solved as well, but the movie "jumps" back and forth when going FSE>FSW...it used to be a lot smoother, only dropping a few frames...now it really stutters and "blinks" back and forth. Also, sometimes the bottom transport bar doesn't appear completely and only the PotP seekbar itself shows up.

After making the bottom transport bar appear and disappear like 30 times in a row, I even got a windows (GDI?) error message stating that there was a memory leak in progress?! It was written in a windows 95/NT4 style msg box and disappeared instantly, huh? I couldn't capture it. I would really appreciate an option to get the <.37 behavior back please, as it was working like a charm and no stutter nor legacy system error msg's when going FSE>FSW

[underzone]

leeperry, where can I get this leeperry skinned potplayer I hear about? I assume I still use ffdshow from the xvid.ru source with it yeah?

Unfortunately, not.
But as I've said before it happens only with "disable desktop composition" and it really is not a big issue (another right click, that's all )
Moreover, unless someone else is having a similar behavior, might be some weird behavior of my machine...

madVR support intel graphic accelerator??
if no...when it will support it??

HoP: Never, to slow.

I was fiddling around with this a bit, and it seems that if I set VSync to Force Off for MPC-HC, the weird stuttering goes away. In exchange I get screen tearing.

While not particularly helpful, it does confirm that madVR is enabling the NVIDIA hardware VSync when in fullscreen exclusive on my system. Tearing with VSync set to Force Off also confirms that madVR Fullscreen Exclusive VSync is also effectively disabled.

What you've been saying about working on a Final Render Path for Fullscreen Exclusive now makes a bit more sense. The problem is the current render path breaking hardware Vsync when enabled, rather than Vsync not enabling at all.

no clue how to make a sample so i uploaded a whole file. it's only around 3 megs though.

http://www.sendspace.com/file/ww7vvr

running mpc-hc with stock decoders, madVR 0.42, nvidia geforce 450 gts 1gb, 265.68 drivers, windows 7 sp1, 1680x1050 60Hz. no clue what else is useful.

edit: just realized i wasn't using stock decoders at all. it's microsoft's decoder's fault.

[ajp_anton]

Just realized how insanely fast the exclusive mode switch is with the new versions. It's almost scary, I barely see any difference between it and "windowed" fullscreen anymore.
Using Win 7 x64, "disable desktop composition" is unchecked.

I used 0.40 for about a minute, skipping through a video I had managed to create serious window garbage all over the screen. Once I closed MPC I started playback again everything was good, I've only used 0.40 once for a hour or so. I will try out 0.42 tonight, Like Leeperry I find 0.36 to be my preference thus far.

I would love to see a feature in MadVR where the name of the file playing back is displayed for a defined time in the same way that the exclusive mode message displays. Would anyone else find that useful?

After using 0.42 for a minute I see when the MPC window resizes as I double click, the image becomes pixelated for a second and the image does a second stretch to fit.
0.36 performs better most of the time in this area but still had the ocassional pixelated image, it also displayed the last viewed frame now and then which I haven't seen happen in 0.40 & 0.42

One issue which has happened twice so far is, as MPC plays the next file in the folder automatically I have my task bar appear. Aero then switches modes and my task bar stays visible and non transparent as the movie plays, however I can't reproduce it.
Great to see that when this doesn't happen the next file plays back without the previous frame popping up and the screen remains black until the next file plays, nice!

I know, right? The funny thing is that each version just gets smoother and smoother for me on the windowed -> exclusive transition. Basically no difference between the two now lol. Desktop Composition off here as well.

I don't think there's anything I can do about it. In exclusive mode nobody else it allowed to draw on the screen except madVR. That's the very definition of "exclusive". madVR has exclusive access to the drawing.

Ok, I think I know what's going wrong, I'll post the follow up to the LAV thread, cause it seems to be a bug caused by the LAV audio decoder.

Oh well. Ok, I've changed some things back to the way v0.36 behaved - but only for Windows XP. I think the behaviour in XP was always fine. Most of the changes for improved exclusive -> windowed switching are now Vista (and newer) exclusive. Hope that you'll be back to v0.36 standards with the next build.

Generally Intel DX9 is supported, but it's rather slow, so if you want to get smooth playback, you'll have to compromise on scaling algorithms.

Interesting. Probably the exclusive mode is simply disabled when you force VSync off.

Thanks for the sample. I've tried in Windows 7 x64 SP1 with an MS decoder, but I couldn't reproduce any problems. Which MS decoder were you using exactly? What did MPC-HC say about the decoder? And please upload a debug log for me, if possible. Thanks.

Happy to hear some positive feedback about the exclusive -> windowed switch improvements!

Which OS are you using? Which GPU? Which madVR desktop composition settings are you using? Do you have Aero generally enabled/disabled?

What makes you think that? Exclusive Mode (Vsync forced off) is not identical to Windowed mode where I get perfectly smooth playback with no tearing. The madVR GUI and stats believes it is in Exclusive mode as well. Would a Debug build log pick that up?

I was assuming Force Off Vsync would just be like running any Direct3D app in Fullscreen Exclusive without Vsync, since Vsync is just an optional feature which can be turned on and off.

I wish there was some way I could help you debug the problem, since I can't exactly send you my GPU.

Well, it doesn't matter, anyway, the final exclusive mode rendering path is coming soon and should fix the problem you're having.

On the HTPC that I saw the window garbage appear I'm running a HD5670 with Win7 x64 with Aero enabled.
