madVR - high quality video renderer (GPU assisted)

[madshi]

madVR v0.70 released

http://madshi.net/madVR.zip

* delay times improved for option "pause playback until render queue is full"
* option "pause playback until render queue is full" is now disabled by default
* exclusive mode tweak options regrouped and branded as "not recommended"
* internal MPEG2/h264 decoders are enabled by default now, VC-1 stays disabled
* display mode switcher now "likes" 24.000 Hz mode for 23.976 fps movies better
* improved timestamps of internal libav/ffmpeg MPEG2 decoder
* improved seeking with internal libav/ffmpeg h264 decoder
* fixed: moving from one monitor to another sometimes caused graph to pause
* fixed: display mode changer caused internal decoders to stop working
* fixed: gamma processing with RGB input produced a black screen
* fixed: h264 mediatype parsing corrupted RAM, eventually resulting in a crash
* fixed: color processing accurateness problems introduced in v0.68
* fixed: exclusive mode seekbar didn't work during DVD playback
* fixed: tracks with a "|" in the name confused the tray icon context menu
* fixed: at playback start, and after unpausing there was sometimes judder
* fixed: OSD sometimes flickered at playback start, and after unpausing

This is mainly a bugfix release, with some minor improvements. I hope that the biggest bugs are all fixed now. If not, let me know. FWIW, I might have to slow down madVR development a bit in the next couple of weeks. So don't expect any major improvements in the next 1-3 months.

So is this all of them?

Could you add keyboard shortcuts for enabling/disabling 3DLUT, enabling/disabling Gamma Correction and enabling/disabling Automatic Fullscreen Exclusive mode?

Current
Enable OSD - Ctrl+J
Reset OSD Statistics - Ctrl+R
Gamma Curve type - Ctrl+Alt+Shift+C
Increase Gamma - Ctrl+Alt+Shift+G
Decrease Gamma - Ctrl+Alt+Shift+F
Source Primaries - Ctrl+Alt+Shift+P
Decoding Matrix - Ctrl+Alt+Shift+M
Input Video Levels - Ctrl+Alt+Shift+I
Output Display Levels Ctrl+Alt+Shift+Y

Depreciated
Decoding Matrix (Color Format) - Ctrl+Alt+Shift+C

[madshi]

"Ctrl+Y" is a typo in the changelog, should read "Ctrl+Alt+Shift+Y", and that key combination is still current for changing the output/display levels. You can enable gamma correction by pressing one of the gamma related keyboard shortcuts twice. Why would you need to switch fullscreen exclusive mode on/off via a keyboard shortcut? A keyboard shortcut for 3dlut is a bit difficult because I'd practically have to "disable all calibration controls" to disable the 3dlut. Is that really the desired effect?

Edit: Ctrl+R resets the statistics in the OSD.

[cyberbeing]

Fixed: It looks like 0.70 fixed the frozen black screen w/ refresh rate changer and the internal decoders bug.


I guess you could make it enable/disable the Calibration page. What I want is the ability to switch on-the-fly between 'Calibrate this dispay by using...' and 'Disable Calibration Controls for this Display'.

As for the Fullscreen exclusive toggle, why not? It would be useful for testing playback differences between Windowed & Fullscreen, as well as being one less thing you need to enter the settings dialog for if you picked the wrong mode (like on my 7800GTX where it doesn't work well). If you can override the default MPC-HC Fullscreen Exclusive shortcut of CTRL+F (especially since it conflicts with madVR settings), that would be great.

But how do you disable it once enabled?

Seekbar works in fullscreen with DVDs now

In ctrl+J when it shows "Movie 29.970 (says source filter)" is that the current fps? I was wondering if IVTC was getting through, it usually shows 23.97 if so in EVR-CP

Thanks for somehow fixing that little bug

What madVR shows is usually the framerate reported by the splitter. It will always be wrong if something is changing the framerate during decoding or via Reclock.

In MPC-HC if you enable View->Statistics it will eventually (pausing the video helps bump it to the correct number quicker when unpaused) show the current fps.

Is there an optimal setting for the gpu flush settings. I have a gtx 570 card, and a corei5 2500k processor and running windows 7 and waching mainly HD-material. What do the settings do excactly?

Kind regards

Great thanks, answers it

madshi, thanks for the new version and for the internal decoders. Is it possible to use them in conjunction with ffdshow AviSynth? (let internal madVR decoders decode)
And how do I make sure madVR internal decoder connects and not player's internal or externals?

Not now. Only madshi knows if it ever will be.

Disable (or block) all other decoders. You can verify madVR's internal decoders are working by looking at the filters. You should not see any video decoders.

[noee]

You can also tell that the madVR internal decoder is being used by checking the ctrl+J stats.

What do the settings do exactly?

There is no one-size-fits-all optimal flush setting. If you are having issues with stuttering panning scenes, tearing, or delayed/dropped frames, you can try playing with the flush settings. Otherwise just leave it as the default.

Their purpose is for fine-tuning madVR for your GPU and computer. Many factors like OS, Drivers, Aero, Subtitles, CPU, CPU load, and DPC latency can influence both your GPU and madVR. Flushing or not flushing after certain steps can at times change how your GPU behaves. Your goal when tweaking should be finding the minimal flush settings which show an improvement but don't cause other issues.

Don't Flush = Don't Flush - No CPU Load
Flush = Make a no-guarantee attempt to flush - Usually No CPU Load
Flush & Wait (Sleep) = Flush no later than 1ms after requested - Low to Moderate CPU Load
Flush & Wait (Loop) = Flush immediately when requested - Low to High CPU load

Flush & Wait (Loop) is somewhat dangerous to use, unless you never experience ANY slowdowns, high CPU load, or things other than madVR fighting for CPU/GPU time. Keep your eye out for increases in CPU load or dropped/delayed frames when using a Flush & Wait setting.

Build # 68 and 70 will not play DVD's. Fault is Nvidia.ax from the fault nag. Went back to an earlier version and all is well. Can you make sure the Nvidia decoders are able to be used as before. I tried with the internal MadVr decoder checked and it still would not play with MPC-HC and the Nvidia decoders enabled/disabled.

Thanks,

MAK

If we are talking nvidia purevideo software, that was made for older hardware and XP

I have new hardware with old software, so you are correct. I am running XP still.

This has definitely improved Thanks so much, madshi. Nice to know that it just wasn't me that was experiencing this...

Edit: Dang! I must have borked something up because it's doing it again. I uninstalled madVR, cleaned it out from registry, re-registered the ax file, but it's still doing it. Tested in Zoom Player and PotPlayer. Juttering upon playback start. I wonder why it was working at first.

madshi, I just checked and there does appear to be a regression after madVR 0.66 with encrypted DVDs and the NVIDIA PureVideo Software decoder on Windows XP. madVR 0.67 has corruption. madVR 0.68-0.70 all crash the decoder. Did you accidentally remove the workaround you had in place for NVIDIA PureVideo's tendency to lie about what it's outputting?

I'm having a problem:

Using the internal h264 decoder, while in exclusive mode, when i unpause a video it takes some time to resume.
It does not in windowed mode or using a external decoder

[Hypernova]

madshi, I may missed it but, is it your intention that internal decoder won't decode h264 in avi? I think this leads to some avi files crash MPC-HC every time I seeked.

Unfortunately no, unless I add AviSynth support myself, which I'm not planning right now.

There are 2 ways:

(1) Look which filters are in your graph. If there's a video decoder filter, madVR is not doing the decoding.

(2) Look at the madVR OSD (Ctrl + J):

madVR decoding: "libav, h264, 8bit, 4:2:0"
external decoder: "h264, 8bit, 4:2:0 -> NV12, 8bit, 4:2:0"

Will check that.

Make sure you reactivate the "delay playback" option because it's disabled by default in v0.70.

This doesn't seem to happen on my PC. Can anybody else reproduce this? A log might help. Try to keep it short, by doing this:

Start the video, go exclusive mode, pause, wait 2-3 seconds, unpause, wait until playback is fluid again, close the media player. Don't do anything else. Every action you take makes the log longer. Thanks.

Didn't check that. Which FourCC does the AVI splitter output? Does madVR even try to decode it (and fail)? Or does an external decoder take over?
