ffdshow HDR? (Page 1 of 2)

Thanks for the info.

So that essentially makes SVP unusable with all HDR content, which is the majority of UHD blu-rays. Do you guys have any plans of transferring SVP outside ffdshow, to something like LAV filters?

Does mpv not use ffdshow?

But still I cannot use madvr or LAV filters with it as far as I know, so I do not understand how it helps?

- it can process 10-bit video
- it can do HDR tone mapping
- it (probably) can pass HDR metadata (probably not?)

It doesn't need madVR and has LAV filters built-in.

I'm saying that Vapoursynth (mpv, VLC) is the ONLY way to pass 10-bit video through SVP.

Is it so hard to open the manual?

yes, it can work in PotPlayer w/o ffdshow
but still only in 8 bit

you are free to ask PotPlayer authors to make built-in image filters compatible with 10-bit color depth

Is there a guide somewhere in layman's terms on how to set PotPlayer up with either vapoursynth or avisynth?

All I found is your thread here: https://www.svp-team.com/forum/viewtopic.php?id=3538

And although I switched: main.setup.potplayer.native = true - the "Use AviSynth filters" is not ticket on every playable file. Now when it is ticked I get this:

global svppath="C:\Users\Admin\AppData\Roaming\SVP4\"
try {
   import(svppath+"scripts\67d6d30e.avs")
}
catch(err_msg) {
   potplayer_source().Subtitle(err_msg)
   WriteFileStart(svppath+"logs\err-67d6d30e.avs.log", "err_msg")
}

But SVP is not working and alternative Vapoursynth never loads. I cannot figure out any other step to take.

Sorry for the late response. I already had ffdshow raw filter removed when I posted, I do not really know where the problem lied but after I reinstalled PotPlayer it seemed to have worked. Something else was blocking it which I will try to find out later.

Now there is still the problem with file playback, for some reason SVP does not work with certain files. This seems like a PotPlayer issue, since on those specific files the "Use Avisynth filters" in the Avisynth section appears unticked and there is no code below it. The problem seems present only with .m2ts files, some work and some do not. Most of the .m2ts files come from their original discs and play properly with SVP with ffdshow.

The only correlation I could find is that if one .m2ts file does not work the rest of related discs will not work either, for example: if "The Matrix" or "Batman Begins" does not work the rest of the trilogy will not work either (assuming from the same disc set?). Other file types like .mkv do not have this issue as far as I can tell but I could only test so many.

Vapoursynth exhibits the same behaviour - but for some reason when I have vapoursynth enabled (through "prefer_avisynth = false" right?) I still see "Use Avisynth filters" ticked/unticked on PotPlayer and not the "Use Vapoursynth filters" in the Vapoursynth section.

I did try restarting/reinstalling everything multiple times for testing purposes.

It mostly does (including HDR conversion), the options are just hidden away in MPV.

They'll all exposed in MPC-QT though. And the few few things it doesn't do natively can be downloaded as user shaders:

If the latest MPC-QT release doesn't work, try grabbing the previous version. I think the latest release broke SVP somehow.

I mentioned this because PotPlayer was a pain last time I tried it with SVP.

Yes of course, I have the following installed:

SVP Manager Pro:
[DS_64] Core for DirectShow 64-bit
[VPS_64] Core for VapourSynth 64-bit

3rd-party software (mandatory):
[DS_64] ffdshow filters 64-bit
[DS_64] Avisynth+ 64-bit

Accordingly, I have a fresh and unaltered installation of PotPlayer for testing purposes. Any ideas on why this is happening? Did I really not miss anything on my configuration as I described previously? I was expecting it to be more complex to be honest.

PS: Also playback stutters/slows down on some of the files with which SVP does work, even though there is no apparent system load issue. In reality, there shouldn't be any issues relating to the system performance at all since technically only PotPlayer runs now without madvr or anything else it previously run along with ffdshow.

I have read about this, that it does mostly everything madvr does. But I do use NGU, among other options, which as far as I understand mpv does not feature yet. Regardless, the main problem is mostly technical than comparative; I have spent hundreds of hours calibrating and setting up PotPlayer with madvr, LAV and SVP. To suddenly move away to another software which has a 3rd-party under-development GUI is not really something I would want. Don't get me wrong, I do appreciate the work being put into it, but I am banging my head on the walls around the house trying to understand software I have already been using for years due to their technicalities and intricacies which are difficult for your average user.
