madVR v0.90.9 released

http://madshi.net/madVR.zip

Code:
* slightly improved SSIM quality (even stronger detail reconstruction)
* removed SSimDetailed option, now SSimClean is always used
* removed "use 1.6 gamma instead of 2.2" option
* fixed: moving media player to another monitor resulted in paused playback
* fixed: rendering eventually left some D3D interfaces open
* fixed: madVR shutdown memory leak
* fixed: some problems with live TV (detected by DVBViewer devs)
* fixed: 1080p23 was forced even when not using "auto" (frame packing)

What do you think how material usually is downscaled?
My wild guess would be that with digital processing, downscaling in GL is most common. But I might be totally wrong.

Hello.
When I use madVr(0.90.8) with PotPlayer x86(1.6.58613 - latest stable version) I get a memory leak. I have recorded a video to show how exactly this happens and what actions are needed to reproduce memory leak. Just in case here is a link for the video that is used in my capture, though it seems to happen in other videos too. On the capture I open the test video and start to rewind video forward by pressing right arrow key with an interval of about 1 or 2 seconds. After some time the amount of modified memory starts to grow excessively and eventually my PC runs out of the memory. In order to free up used memory PotPlayer have to be closed.

PC specs:
Windows 7 x64 sp1
32 GB RAM
8192 MB Page File
1280 MB VRam
GeForce 361.75 driver.

Mirrors for videos(test + capture) on mega:
https://mega.nz/#!u1EUAICT!JloZaFVjb...GXAALzAzVvbK04 - test video
https://mega.nz/#!b8MWibza!aDVDMYdEK...zE38QyZrkk1x4c - memory leak capture

My MadVr settings:

Thanks for the new release.
With 0.90.9 + Kodi Dsplayer i'm getting black screen when playing (sd, 720p or cropped 1080p) > UHD while 1080p & UHD > UHD is fine.
switching to D3D11 presentation fix the problem but unfortunetly my IGPU struggle with D3D11.
none of the above problems occures with MPC-HC X64.
X86 bug?

Problem with massive CPU usage when playing 4K videos on a 1080P Display

when playing 4K videos GPU usage is non existent while the CPU usage for my i7 2600K @ 4.6Ghz works at 80%!
im playing these 4K files from 1080P res in windows.
i havev tried different settings to see if the usage can move over from the CPU to the GPU but its the same with any setting i use.

this only happends when i play 4K videos
playing 1080P material GPU usage is back to normal around 80% (GTX 780) and CPU usage almost 0

any suggestions on how to force the GPU to take care of these 4K videos?
even a 4.6Ghz CPU isnt able to render all frames here
stutters like crazy.

some of them but its the same with all 4K videos

its the 4K demos from here
http://demo-uhd3d.com/

it must be the downscaling to 1080P that screws it up ?

@Patrik G

HEVC is decoded by the CPU alone by LAV Video decoder if your GPU does not support HEVC decoding.
Next gen video cards which will be able to off-load the decoding to the GPUs VPU (video processing unit), like current GPUs doing with x264.

The only GPU of current gen that able to decode HEVC is Nvidia GTX960, and yes, the CPU and GPU remain around 0% because the VPU completely takes the full load.

* VPU is a separate processor on the GPU that used solely to decode video. Like on a hardware Bluray Player.

ok thanks
i will get a 960 or 970 next week
GTX 780 is starting to getting old it seems.

if someone wants to buy 2 watercooled GTX780s just let me know

For some reason only the 960 has the hardware to decode x265/HEVC, the 970 or 980 do not.
https://en.wikipedia.org/wiki/Nvidia...#Feature_Set_F

You should wait for next gen (Pascal) if you're a gamer and don't buy the 960.

that was bad.
but ok i dont play any games so i guess a 960 would do the job for movies only.

Edit: i probably wait for the nextgen Nvidia cards.
its a huge dip in performance from a 780 with the 960s.
it feels like an downgrade.

That's very misleading unless you add the 10-bit caveat to it. Intel has full HEVC decoding for 8-bit in Skylake and some of the low power solutions like Braswell too.

Yes, thanks for the correction Stereodude.
Intentions are all good.

Still, if I were to build a new HTPC with Nvidia GPU, I'd wait for Pascal which should begin to appear on Q3 of 2016.

While playing a 1080i59 video file, if I double click on another 1080i59 video file to play it in the same video player window, I get a blank screen with sound from the new video. I also previously was able to drag the video player window from one screen to another screen with no problems (just a minor pause in playback), but that now usually gives a blank screen with audio playing with an occasional DirectX fails to render crash.

MPC-HC 1.7.10 (64-bit)
LAV Filters 0.67.0
madVR 0.89.12 - ok
madVR 0.89.13 - fail

Windows 7 64-bit
NVIDIA GTX 670 video card

madVR settings:
D3D9 overlay
NV12, 8 bit, 4:2:0
movie 29.970 fps (says source filter)
movie 1920x1080, 16:9
touch window from outside
chroma > Jinc AR
image < Lanczos3 AR
vsync 16.68ms, frame 16.68ms
matrix BT.709 (says upstream)
primaries BT.709 (says upstream)
limited range (says upstream)
deinterlacing on (settings)
...

I haven't updated for quite a while, but with all the great work being done, I thought I would give the 3D playback a try. That is when I noticed the problem described above.

Thanks for all the great features and hard work.

Then v0.90.9 was released:

Hi madshi, it looks like vobsub rendering got broken again, but this time different than the last time. It's affecting 1920x1080 vobsubs made from BluRay sups, or the sups themselves. Small DVD vobsubs don't have this issue. The subtitles are visible when the player is in full screen mode on a normal 1080p screen, but they don't show up when the player is not in full screen mode (btw, I am not speaking about full screen exclusive mode). My guess is that the subs are not downscaled when the video is downscaled. EVR custom presenter renderer in MPC-HC in the same scenario works fine.

I put here a sub/idx sample, and my settings.bin file. You can use the subs with any media file, as long as it's longer than 5 minutes (the first spoken line starts ~ 5 minutes, as can be seen in the idx file).

Later edit: it happens the same when playing m2ts files from a BluRay, so it's not only vobsubs, but sups as well.

Last edited by KoD; 14th February 2016 at 00:36. Reason: added note on playing BluRay content directly, and removed note on vobsubs roughness as it was not visible on original sups

Could someone compile a package of examples with visual differences between different madVR settings, including most chroma upscaling, image upscaling, image downscaling, image doubling + quadrupling, SuperRes, ER Diffusion and a ton of other settings on different kind of content, such as HQ 1080p, MQ 1080p, LQ 1080p, same for 720p and then for 4xxp... It would be a pretty comprehensive and LARGE package of examples, but shouldn't there be one just like that?

On what page should I start looking for SSIM downscaling examples to see difference between Catmull-Rom and SSIM?

I use these settings for SD and HD content (480p, 720p and 1080p) on my 1080p display with MPC-HC + LAV Filters (DXVA 2 Copy-Back Hardware Acceleration):
- 3DLUT
- 10bit 0-255 output on 12bit output display
- Artifact Removal - Low (top setting), Medium (bottom setting), but depends on content quality
- Chroma Upscaling - NNEDI3 64n + SuperRes (Strength 3)
- Image Downscaling - Catmull-Rom + AR + LL
- Image Doubling and Quadrupling (Luma only) set to Always
- Image Upscaling - Jink + AR
- Upscaling Refinement - SuperRes 3
- Dithering - Error Diffusion Type 2 + Colored Noise and Change Dither every frame
- D3D11 Exclusive Mode (3 frames in advance)
- Everything disabled in Trade Quality for Performance

These are obviously GPU-hungry settings for 480p, 720p, and 1080p content even for my 3770K @ 4.8Ghz and GTX 980 @ 1550Mhz. What settings do you recommend to try for:
1. 480p, 720p, and 1080p content upscaled to 4K on 4K display?
2. 4K content @ 4K on 4K display?

Obviously I want the best image quality and no lost or dropped frames and no presentation glitches.

madvr crashes with MPC-HC 64bit version but not with 32bit
why is that?

and only when i enter fullscreen not in window mode

crash report

1807 pages of issues and you still isnt able to have a fully working video renderer lol
