mpv.conf - having issue configuring scaling

[Chest Rockwell 3]

Guys (esp. Doofus),

 

I am trying to configure ET for better upscaling.   However, I have run into an issue.  In particular, it does not appear that MPV is using the scaling options I am setting in mpv.conf.

 

I know my mpv.conf file is being read because I have it generating log files. In addition, as a test case, when I set “video-unscaled=yes,” the image is not scaled and, as expected, there are black bars surrounding the picture.  I am attempting to upscale 480i video material to 1080.  My computer has an i7 four core Kaby Lake and an nVidia GTX 1080 video card.  In Emby Theater I turned hardware acceleration to “none” to avoid problems.

 

Whether I set “scale=” to low fidelity algorithms like “nn,” “oversample,” “bilinear,” or whether I set it to “ewa_lancozsharp,” the scaled picture looks the same on my 1080p monitor, and I have some experience comparing scaler outputs.  In addition, my CPU/GPU usage is exactly the same at 5%/32% no matter what scaling I specify. I also tried, “profile=gpu-hq” with the same results.  I have deinterlacing set to "yes" in ET, so whatever is default is being used.

 

My mpv.conf is simple:

 

Log-file=”C:\mpv logs\Theater mpv log.txt”

msg-level=v

gpu=vo

hwdec=no

scale=[one of: nn, oversample, bilinear, ewa_lanczossharp]

 

I have looked at the log file and, unless I am missing something, it does not seem to indicate which scaling algorithm is being used.   Is there a way to confirm which scaling algorithm is being implemented by MPV at run time?  I have attached a log file that was generated when I had "scale=oversample".

You're trying to use a hardware scaler with no hardware acceleration. Just enable 'auto' in Theater for hardware acceleration, and use this in your mpv.conf. The extra stuff will help clean up artifacts.

For anyone wanting to be able to see if your options are working, run the config for mpv standalone. When playing, press shift+i, then press 2. You'll see, this:

Doofus,

 

Thank you for the reply.  I do have a couple of follow up questions. 

 

First,  I created an mpv.conf file exactly as you stated above. I also put the ET app into "auto" for h/w acceleration. I  am still not certain that the scaler selection in the mpv.conf is being honored.  Again, I can't see any difference between default, oversample, and ewa_lanczossharp when close up to the screen on still images and my CPU/GPU utilization is a constant (3%/37%) regardless of scaling algorithm specified.  In addition, if you look at the attached log, there is a line:

 

[  0.899][d][ffmpeg] auto_scaler_0: w:iw h:ih flags:'bilinear' interl:0

 

Doesn't this mean that bilinear is being used even though the mpv-conf specifies ewa_lanczossharp?

 

Second, I then added the line vf=bwdif to activate the improved deinterlacer. The log file states that: 

 

[   0.900][f][lavfi] failed to configure the filter graph

 

[   0.900][e][vf] Disabling filter bwdif.00 because it has failed.

 

Also my CPU/GPU utilization did not increase at all when I added bwdif.  In earlier experiments, I could not get bwdif to work when any hardware acceleration was being used.  This is why I had disabled all h/w acceleration.  Do you know how to get bwdif to work when there is h/w acceleration?

 

Thanks again.

I thought it we were supposed to use unset (for MPV.conf) at the very bottom of the ET hardware acceleration settings to get it to read MPV?

Iorac - thanks for the tip.  I did not even see that option (on my screen it required scrolling down to see it).  Now that I have selected "unset" in ET, the log is no longer showing "bilinear."  However, I still need to do some more testing to verify that the scale= command in mpv.conf is being honored.  Additionally, bwdif is no longer failing, and the log seems to indicate it is being used.

[lorac 100]

Having at the bottom really isn't the best place for that option. Until I was told about it i didn't know it was there either.

You're confusing yourself. bwdif is an ffmpeg software deinterlacer. Why are you trying to use that instead of deinterlace=yes? You're making things difficult for yourself. There are software scalers that you can use, but that's a beast of a way to go, especially when you have a great GPU. Try enabling auto for deinterlacing in the Theater settings, and auto for hardware acceleration, use the config I gave you and you should be fine.

That's not relevant, here. That's only if you want to set the option in your mpv.conf. In this case, he's playing old SDR stuff. Using auto for hardware acceleration, is recommended.

If you really want to complicate this, you can use Unset, and create auto-profiles that will enable and disable your options/settings based on content. But I'd have to write you a config for that and provide the necessary files..... I have other things to attend to.... You shouldn't be messing with advanced configs if you don't know what you're doing. It's working because hardware acceleration isn't being used... 

[Guest asrequested]

If you use deinterlace=auto in Theater, with hardware acceleration=auto, on Windows it will use this:

 

https://mpv.io/manual/master/#video-filters-d3d11vpp

 

It will deinterlace, very well with your GPU.

[Chest Rockwell 3]

Doofus,

 

When I used your script (w/ scale=ewa_lanczossharp) and h/w acceleration was activated (ET h/w acceleration set to auto), the log shows the "auto_scaler" being set to "bilinear."  See second log file.  Do you know why that might be?   And as I indicated, using your script the cpu/gpu usage was the same, auto_scaler shows bilinear in the log, and image quality appeared to be the same, regardless of what scaling option is used for scale=.

Post screenshots of all of your settings in Theater and the mpv.conf you are trying to use.

As I explained, you are using a software deinterlacer (bwdif):

It isn't a post processing filter. It's either/or. If you want to use a software deinterlacer, then you have to disable hardware acceleration and use a software scaler. You are causing a conflict of mechanisms, and the hardware acceleration will win, because it's the decoder. Stop using bwdif and enable auto deinterlacing in the Theater UI.

Thanks for the feedback.  I will play around with it.  Your posts have given me some more insight into how this all works.

@@Chest Rockwell Sometimes I'm an idiot and I forget things

 

Enable one of the copyback modes for hardware acceleration, and you should be able to use those video filters. As you have an Nvidia GPU, I'd suggest nvdec copyback. To test with, I used auto copyback. Results below:

Per your suggestion, I was able to use D3D-copyback and get bwdif working.  At first, I was seeing some artifacting in moving edges.  But then I realized that I also needed to change "Enable Deinterlacing" in ET from "yes" to "no."   If it is set to "yes," then both the hardware deinterlacer and bwdif are active and interfere with one another.  Once I changed it to "no," only bwdif was operative and things looked like they were deinterlacing properly.  

 

Do you know what the above-quoted lines from your log are referring to?  What does it mean for the auto_scaler to be set to "bilinear" even though you have selected ewa_lanczos for scaling?  I could not find anything online as to how to interpret the log.  It appears this auto_scaler might be doing some sort of chroma conversion or chroma scaling?

It's just the internal processing for the filter. Bilinear is the fastest as to not impede the process, and upscaling to the display happens after that. That's why, if you look at my screenshots, --scale is toward the end. Decoding and image changes first, then upscaled.

[Chest Rockwell 3]

Doofus,

 

Okay, after a few days of experimenting, I seem to have most everything working.  I am using D3D11va-copyback.  I have scalers working, and for deinterlacing I can activate either bwdif software deinterlacing or vf=d3d11vpp hardware deinterlacing.  I even have the FSRCNNX shaders enabled and auto profiles set up for SD and HD content.

 

There is an issue I have noticed, however.  When I use the hardware deinterlacer, the mode option is not being honored.  I am using the same h/w deinterlacer that you are in your mpv.conf:

 

vf=d3d11vpp=deint=yes:interlaced-only=yes:mode=[blend, bob, adaptive, mocomp, ivctc]

 

When I call this h/w deinterlacer for interlaced SD content, it does deinterlace the video.  And I know it is the d3d11 deinterlacer being activated because if a put a pound sign (#) in front of it, the video is not deinterlaced.  Similarly, if I set "deint=no" then the video is also not deinterlaced. However, I have noticed that regardless of what option I set mode to, the deinerlacing looks exactly the same.  I confirmed this by using the Spears & Munsil "jaggies" deinterlacing test pattern (the one with the rotating bar).  Regardless of whether I set mode=blend, bob, adaptive, mocomp, or ivctc the test pattern looks exactly the same.  It should be very easy to tell the difference between blend and mocomp on such a moving test pattern.  As I wanted to use d3d11vpp for both deinterlacing and inverse telecine, it is important to me that the mode option be honored.

 

Are you able to confirm with your configuration that when you change the deinterlacing mode, that selection is being honored?  I suspect there might be a driver problem. It seems that there is only one deinterlacing algorithm being called regardless of how the mode is set.  I will say that based on the test patterns, the default algorithm that is called is actually pretty good.

The thing with hardware deinterlacing is that the hardware may not support all of the options. The hardware will do only what it's capable of doing. Maybe you can find some docs on your GPU that will give you that info? Or just use software. There's a plethora of options with software. Have you looked at the bwdif configs?

[Chest Rockwell 3]

I can get bwdif to work for deinterlace, but it does not have a mode for inverse telecine.  Because I have a mix of 480 video and telecined content, my goal is to eventually use autodeint scripts and auto profiles to deinterlace or inverse telecine as needed.  I have deinterlacing basically figured out and am now working on figuring out inverse telecine.  The d3d11 h/w has a IVCTC mode but I could not get it to work, which led me to discover that the mode option does not work.

 

As I have a GTX 1080 and I believe that you have a 1060, and we are both using the d3d11 deinterlacer, I figured that If the mode option does not work for me it is probably not working for you either.  But as I indicated, whatever the default deinterlacing mode is, it is pretty good.  It's just that I can't put my Nvidia card into an inverse telecine mode.  I guess I will need to experiment with fieldmatch/decimate filters. 

[Guest asrequested]

I think something may be broken. I was just testing this:

 

 

And it doesn't work at all. I have an RTX 2060, so maybe it doesn't work with the newer stuff? Maybe you could try it and see if it works with your GTX?

 

But there are several other software deinterlacers. If you can't make that work, then one of us should make an issue report to mpv.

[Guest asrequested]

You can always use the --detelecine filter. Just run it vf=lavfi-detelecine

 

https://ffmpeg.org/ffmpeg-filters.html#detelecine

 

So you could run them as a string:

vf=lavfi-bwdif:deint=1,lavfi-detelecine

Edited February 8, 2020 by Doofus

[Chest Rockwell 3]

I switched to cuda-copy and tried vd-lavc-o=deint=adaptive.   It does not seem to work for me either.  I also  have not been able to get the vdpaupp h/w deinterlacer to work.  The only h/w deinterlacer I can get to work is d3d11vpp, but as indicated above it does not honor mode selection and uses some default algorithm.
