madVR - high quality video renderer (GPU assisted)

[mindz]

SamuriHL, care sharing your script with me? Would be great! My email is rogercomley@gmail.com.

[SamuriHL]

My script is very specific to my machines. I hardcode my paths into the installer and my scripts that install do so from very specific locations on my network. So they wouldn't help anyone else which is why I don't bother releasing them.

* fixed: encrypted DVDs didn't play
* fixed: DVD menu "clickable areas" were not always located correctly
* fixed: DVD menu buttons near the FSE seekbar didn't work
* fixed: some minor cosmetical improvements to DVD menu rendering
* fixed: seeking DVDs in fullscreen exclusive mode didn't flush the decoder
* fixed: frame stepping should now work perfectly
* fixed: MPC-HC froze when creating thumbnails
* fixed: MPC-HC froze when seeking DVDs in Windows XP
* fixed: scaling settings were not always remembered after "restore default"
* 50i and 50p SD sources are now auto detected as having PAL/EBU primaries

Playback of encrypted DVDs should now work without having to decypt them first !!! Please test this, especially on win7 and win8 and let me know if it works for you.

I've had to change some aspect ratio and video size related information behaviour in madVR to make the DVD Navigator work better. I hope there are no negative side effects. But it's possible some smaller follow-up bugs could show up. Let me know if you find anything...

Thanks a lot for the new build, madshi.

I have one DVD where the DVD menu is not working correctly. The main menu is working perfectly fine, however, If I go into the languages selection I cannot select various options with the mouse (the mouse cursor acts like the option isn´t there) and they are also not highlighted. It works fine with the keyboard up/left/down/right keys, though.

What do you need from me to fix it? I can upload the DVD menu if you want, I already have it RARed on my HDD.

This will avoid the "thinning of light on dark features" that using perceptual spaces introduce. For example, this would have a large impact on the "robot" test image (a.k.a. "6233638's very clean computer type image").
TTBOMK, linear light is pretty much the only safe way to handle pathological cases (e.g. digital half-toning).

Well, madVR already has an option to use linear light scaling with or without AR, so there's nothing I need to do...

Ouch, will be fixed in the next build.

Yes, but with lower deinterlacing quality.

Please first check if the same DVD plays fine with VMR9 (not EVR). If it plays fine with VMR9, then please upload the DVD. Otherwise it might be a bug in LAV Video Decoder (are you using the latest LAV DVD test build?). Please double check with a different decoder with VMR9 then, to make sure.

OK, it seems the DVD is at fault here. Just double checked with VMR9. For some strange reason you cannot choose languages and subtitles in the languages selection directly. The mouse only works if you select another option on top or beside it and only then you can select the option you want. Usability at it´s best. Sorry for your time.

So as far as madVR is concerned, what does that mean for native 4:2:2 video which is interlaced?
Will such video continue to be de-interlaced by madVR in the next build?
Does the '4:2:0 only' error mean that madVR will/does sub-sample 4:2:2/4:4:4 chroma to 4:2:0 before passing it off to deinterlacing?
What are the options for real-time playback 4:2:2 MPEG-2 & H.264 deinterlacing of better quality than DXVA2?

[madshi]

madVR downconverts 4:2:2 video to 4:2:0, so DXVA deinterlacing is performed with highest quality. The "4:2:0 complaint" is a bug, as I said, it will be fixed in the next build. Simply ignore it. IMHO deinterlacing of 4:2:2 and 4:4:4 content is extremely unimportant because it's very rare. As a result I'm not interested in getting headaches about it right now. There are still many far more important things to do.

[dansrfe]

I can't turn off deinterlacing via Ctrl+Alt+Shift+D anymore with DVDs because I get the warning: deinterlacing is only supported for YCbCr 4:2:0 sources.

16:23:53 <LexSfX> hmmm
16:24:11 <Underground78> ah?
16:24:22 <LexSfX> it still has the issue i reported, where if you frame step a while forward, then once back, it goes all the way back
16:24:46 <Underground78> strange I had the impression it didn't do that anymore
16:24:53 <LexSfX> or, well
16:24:57 <LexSfX> it does it only sometimes
16:25:06 <LexSfX> try holding ctrl+right
16:25:10 <LexSfX> for like 2 seconds
16:25:18 <LexSfX> then without releasing ctrl, press left
16:25:46 <LexSfX> goes all the way back to the beginning of the seek with one left
16:27:35 <Underground78> it seems I can't reproduce
16:27:46 <Underground78> are you sure it's specific to madVR?
16:30:45 <Underground78> ah stupid me -_-
16:30:52 <Underground78> just thought about something
16:31:23 <Underground78> if I don't select madVR of course reproducing might be more difficult...
16:37:10 <Underground78> yeah you're right :(
16:37:17 <Underground78> I will have a look again later

So, it doesn't seem completely fixed for me. I'm not sure. I'm posting this here so you see it, madshi.

Oh yeah, DVD support with madVR & LAV.
Simply great, thanks.

OK thanks.

Quick question: Right now I'm using MPC-HC+ffdshow+madVR+Directvobsub and I'm upscaling the video using ffdshow (to desktop resolution) so that subs wouldn't look like crap on low resolution videos but because of this, I can't benefit from madVR's HQ scaling algorithm since the video is already upscaled by ffdshow. Are there any other alternatives in which case I can get HQ subs without having to do the upscaling using ffdshow and instead use madVR for that? Using MPC-HC's internal subtitle renderer is out of the question because it fails to render even not-so-advanced typesetting properly (yes, I know MPC-HC uses the same code as Directvobsub but they most certainly draw subs differently).

Ok, will look at it, but to be honest, the remaining problem is very small compared to the original problems...

The latest madVR build supports a new subtitle interface which has several benefits, one of them is that it should allow to render subtitles correctly in final movie output resolution while still allowing madVR to do the video scaling. Unfortunately there's no subtitle renderer available yet which makes use of the new interface. xy-vsfilter is supposed to support this interface sooner or later, but the xy-vsfilter developer is taking a break, so it could take some time (maybe a loooong time) for this to happen.

What is this "advanced typesetting" that the MPC-HC renderer cannot handle properly? A year or so ago it couldn't handle alpha-blending but that has been resolved for awhile.

If you haven't tried the renderer on the current-release MPC-HC I suggest you give it a shot. I personally would very much like the know the filename/see the subtitle script of a file that does not render its subs correctly.

05:18:46 <Underground78> now it seems to really fix it
05:18:47 <LexSfX> got it already
05:18:49 <LexSfX> and tested it
05:18:49 <Underground78> ok
05:18:57 <LexSfX> still slightly broken
05:19:16 <Underground78> are you alexfolland on SF?
05:19:19 <LexSfX> the easiest way to reproduce it is to hold ctrl and alternate left and right quickly
05:19:19 <LexSfX> yes
05:19:24 <Underground78> oh ok
05:19:39 <LexSfX> you'll see the video proceed forward
05:19:45 <LexSfX> even though that should definitely not happen
05:20:03 <Underground78> can't reproduce
05:20:17 <Underground78> so either it's related to the video or the computer
05:20:21 <LexSfX> try on a laggier (bigger, more cpu-intensive, i guess?) video
05:20:24 <Underground78> or maybe I'm not fast enought
05:21:44 <LexSfX> anyway
05:21:46 <Underground78> indeed
05:21:50 <LexSfX> it's not nearly as much a problem
05:21:53 <LexSfX> as it was before
05:21:55 <LexSfX> it's way way better now
05:22:30 <Underground78> yeah I'm not sure we can do something better
05:22:33 <LexSfX> so thank you very much for looking into it, as frame-stepping to see exact art in animation is something i do often while casually watching stuff
05:22:53 <LexSfX> this is very very helpful for me personally, anyway
05:23:12 <LexSfX> i can't express my appreciation for what you and madshi have done enough :)
05:23:27 <Underground78> well mostly madshi ^^
05:23:32 <LexSfX> yes, mostly madshi
05:23:47 <LexSfX> but you had to care too, which takes a certain something
05:23:57 <LexSfX> idk! anyway, off to watch anime ;)

So, thank you, madshi! Also, I'm AlexFolland on SourceForge. I agree with Underground78's statement that there's probably nothing better that can be done and I am satisfied with the current state of frame-stepping with madvr in mpc-hc.

Thank you very much for DVD playback! No need to convert DVDs to .mkv now!

Please have a look.
I start playback then seek, then switch 23->59 (Film -> Video) and audio starts stuttering, and madvr drops frames.
It happens only when audio is Dts-HD MA.

The log:

Thaks!

Glad to hear it's working ok now.

According to the log the rendering queue never fills again (stays at max 2/8) after the switch to 59. Are you sure your GPU is fast enough for 59 playback?

I guess, ATI 5750 is fast for that playback.
