madVR - high quality video renderer (GPU assisted)

This option begs for clarity IMHO.

I will not change anything about that until I redesign the settings dialog, which is planned for a future release.

Hi !

0.16 crashes the player (zoomplayer). I have attached the logfile to my post. 0.13 worked fine (except for some judder which does not happen with the Haali Renderer). I have not tried 0.14-0.15

Bye,
Alex

In "all spline64", which I assumed a stress test, the loop is needed to get rid of stuttering. After further testing, I only need it in "after render steps". I can leave "after last step" to don't flush and it seems fine. However, if the choice exist, I think the loop for "after last step" work a little bit better, in the sense that it looks "smoother".

I tried changing chroma to softcubic100. In this setup, I don't need flush at all.

Info:
(1) ATi 3870 with 512mb ram
(2) Windows Server 2008 R2
(3) Aero on
(4) 2560x1600 + 60Hz (madVR stat say ~59.80).
(5) Single monitor setup.

well, I prefer avoiding flushing altogether...I might be imagining things but flushing seems to fight/confuse/lag against Reclock's timings. It seems to make mVR behave like Overlay..."no question asked, follow the damn timings already"

I implemented it as a last resort if your freezing/crawling problem was still not fixed. If you only get a small hiccup now with v0.16, would you be ok with me removing that option again? The hiccup is not nice. But in return you get faster rendering times.

Well, the hiccup is really not nice to look at...I'd very much like to keep the option if any possible please

This current config looks so amazing, I can't really believe how smooth it is atm

I've asked Kazuya to try my settings(he runs XP SP3/nvidia/same HC3100 pj as mine etc etc) and confirm whether I'm imagining things.

hehe, ok no biggy...well, please don't add any other option after this one...hopefully there's only 4 flushing options? hope I'm not already missing something.

Big fonts work fine in the apps I use...I also don't run a pagefile, I like to live dangerously

ok, but I guess the goal is to make mVR easier to use for newbies...this is not helping.

PS: oops there's a fifth flush option, it doesn't show up due to my big fonts...good thing it's disabled by default.

Which OS are you using? Which GPU? Display mode? Refresh rate? Aero on/off? When does the crash occur, right when starting the video playback, or after a couple of seconds, or when you do something special like switching between windowed/fullscreen? Does the crash occur with all videos or just with some? Which decoder/splitter are you using?

[namaiki]

1920x1080x60, 9600M GT (187.45), Windows 7 x64 (Aero on), MPC-HC, CoreAVC (software), VSFilter, Reclock (not with vsync correction).

My setup seems to hate 'flushing after present' a lot and also does not like 'flushing after back buffer'.

It seems I can have all flushes off or on. With all off, there is lag but this soon goes away.

With default flush settings is mostly fine (I would say I am satisfied and will be using them for now), except sometimes there is a little 'jump' when subtitles come on the screen (same with all combinations so far, so probably discount this).

(testing both 23.976 and 29.970 fps material)








leeperry, are you still using Reclock's own VSync correction?

[Grmpf]

Great new version madshi, even if 0.13 was *THE* biggest step for me (removing of the dreaded tearing). I found that your default flush options were good for me too and the "use managed upload textures (XP only)" had to stay off...

Intel Q9550 + ATi 4770 + JVC DLA HD100 (24.976/24.000/50.000/59.940hz) - single display
Win XP SP3 + ZoomPlayer + Haali Splitter + CoreAVC(H.264)/Win DMO(VC-1) + madVR + ReClock (VSync off)

One thing i wouldn't like to see is having flush(loop) as standard anywhere without the possibility to switch is to (sleep) because of the cpu eating... Beware, small rant coming: I need all the cpu power i got (my system is slightly overclocked) to decode VC-1 stuff + deinterlacing, because there is not one single good vc-1 decoder out there, ffmpeg is crap (does not work with interlaced content), the windows dmo is crap (single threaded), etc. and if you have to deinterlace using cpu power (no hardware deinterlacing with madvr) you get 80-95% use of one core while 3 cores are next to idle at ~5%... and no i do not want skip the interlaced content, because there are some great concerts on blu-ray out there which are interlaced vc-1/h.264, so there is no way around software deinterlacing imho. Because of that i would love to see madvr using as less cpu power as possible or have atleast the option for it.

Ohh and thank you madshi for the rapidly ongoing development of madvr !

nonoonoo

madshi; ajp_anton: Green bar at the top of the video on non mod-16 video seems to only occur if you are using MPC-HC's internal video decoder.

[Grafisher]

0.16 is hanging the player on startup. It looks like the playback is paused, and one of the CPU cores is fully occupied. I have about 50/50 chance that this happens when I open a video. I have attached a log from the debug version.

I use Zoom Player, Win7 x64, Aero on, ffdshow, default madVR settings, GTS 250.

[namaiki]

Grafisher: Did this occur with other MadVR builds? Does it occur if you are using MPC-HC? Also, what Forceware are you running?

Attaching files to this forum is a BAD idea. It takes ages for the attachments to get approved. Better upload the log file elsewhere...

madshi!!! I just got 1920x1080x60 for a 60fps video fully smooth on my 9600M GT!!! GPU usage according to GPU-z is ~90%

settings are: all flushes off except for

After render steps: flush and wait (sleep)
after last step: flush

this exact combination only produces fully smooth video for me for 60fps video

I swear, just then when I discovered it, my eyes nearly popped out of my head.

9600M GT (187.45), Windows 7 x64 (aero on), Reclock, MPC-HC, CoreAVC 2.0

Could others please try these settings and report findings:
After render steps: flush and wait (sleep)
after last step: flush

Not sure if it happened in any previous version. Perhaps you are aware of this already?

There appears to be a bug in ffmpeg-mt with the Elephants video. FWIW, the h264 bitstream reports 720x406, but the container says 720x405. CoreAVC and DixV decoders have no problem with this situation. But ffmpeg-mt doesn't start delivering frames to madVR in this situation on my XPSP3 dev PC. The strange thing is that ffmpeg-mt connects to madVR with 720x404, which is definitely wrong. madVR still accepts the connection. But then ffmpeg-mt keeps on asking whether madVR would be happy with 720x406, too. And madVR keeps on saying "yeah, sure". But ffmpeg-mt doesn't try to connect or to send frames, it just keeps asking the same question all over again. Neither CoreAVC nor DivX do that. I guess that the green lines also has to do with that somehow. My suggestion would be to try other decoders.

No, this is the first version with which it occured (no idea about 0.14 and 0.15). I don't use MPC-HC. Forceware 197.45.

Nice!

Is it not fully smooth with the default flush settings?

Your GPU is *painfully* slow with reporting scanline information. I'll have this worked around in the next build. But I'm not happy about NVidia drivers being so bad in this aspect.

Laggy for the 60fps video, but otherwise is fine for 23.976 and 29.970 fps video.

[cyberlolo]

No problems here and everything's perfectly smooth with all flushes disabled. My setup:

CPU: i7
GPU: ATI Radeon HD4850
OS: Win7 Ultimate x64
Player: MPC-HC 1.3.1788.0. Tests made with KMP too.
Decoder: CoreAVC 2.0
Aero: on
Display resolution + refresh rate: 1920x1080@24/50/60 Hz (depending on source)
Single or multi monitor setup: I've got 2 monitors connected to the card, but only one is enabled at the same time, so single monitor.

Tested 23.976 fps (@24Hz) and 25 fps (@50Hz) content.

madshi, is this enough or do you want me to test your default settings with my setup? (I think if I don't have any problem with no flushes, I won't have them flushing, will I?)

Not true for my setup. Please try my settings. I'm still grinning like an idiot, inside and out.
