Media Player Classic - BE Win32/x64

[butterw2]

For Nvidia Video SuperResolution, there has been an Nvidia blog post and very mixed user reviews. For Intel, there was just some press coverage of the chromium commit.

Using mpc-be with mpc-vr dx11, I've noticed that when I open the shader combiner interface "Shaders > Select Shaders..." the combo-box always starts on dx9. However, the user would need to use dx11 shaders in this case. Would it be possible to modify so that the selector is set to the display mode currently in use (ie dx11) ?

The problem here is that MPC VR can be inactive. And I don't want to look for renderer settings in the registry.

In commit 9643c21 I made it so that the choice of DX9/DX11 depends on the renderer selected in the settings and the Windows version. This will close the issue on typical configurations.

Is there a way to play HLG files in HDR10 or HLG passthrough? Tried a couple of HLG files that Kodi handles well and they played back in SDR.

Yes - use MPC VR.

Right. I had tried but I made a dumb mistake... it works. Thanks a lot.

[ashlar42]

Hmmm... it works with some files and not with other files. I uploaded here two very small videos, one working, the other not working. Meaning one activates HDR and the other doesn't. Both work fine in Kodi 20.1.

Let me know if any other info is needed to help solving this.

one file is not HLG it is BT 2020 (what ever that means for transfer).

do not forget wikipedia is not reliable for video specs.

Mediainfo for "non working" file states:

Color range : Limited
Color primaries : BT.2020
Transfer characteristics : BT.2020 (10-bit)
transfer_characteristics_Original : HLG / BT.2020 (10-bit)
Matrix coefficients : BT.2020 non-constant

Mediainfo for "working" file states:

Color range : Limited
Color primaries : BT.2020
Transfer characteristics : HLG
transfer_characteristics_Original : HLG / BT.2020 (10-bit)
Matrix coefficients : BT.2020 non-constant

Now, I have zero knowledge about the implications but the "non working" file is displayed in HDR through Kodi and it's quite clear that HDR picture information is there.

So, maybe the "transfer_characteristics_Original" value is the correct one, I don't know.

One extra question, on MPC VR:

I don't see where to set range output. I need limited range, that's how I have calibrated my display. But MPC VR is outputting full range and I don't see where I could change that.

In madVR I have set "The display expects the following RGB output levels:" to TV levels (16-235) and colors are correct.

i get this for not working:
Color range : Limited
Color primaries : BT.2020
Transfer characteristics : BT.2020 (10-bit)
transfer_characteristics_Origi : HLG / BT.2020 (10-bit)
Matrix coefficients : BT.2020 non-constant

and this is not HLG the mpcVR is also seeing this as none linear bt 2020 (pretty much means ~gamma).

mpcVR doesn't have a range option(and i support this).
you can still do this using shaders.
should be the first one under shader make sure you match the DX version.

As stated, I don't understand what all this means. I'm simply reporting that in Kodi I get correct HDR output for the non working file. Now, it might be an incorrect tagging/encoding/whatever. But Kodi makes it work just the same. If there are cons to that approach I don't know. Which is why I prepared the files, etc. Hoping to help in making MPC-BE work better (if it makes sense).

Yeah, I see there's a bit of a "religion war" on the subject. If one calibrates their TV correctly, limited range is the way to go but I absolutely don't want to go into that, since I got the impression it's already been debated to death. If you want to explain in a PM what it is all about, I'd appreciate it. But I don't wanna clutter the discussion here. :-)

If the shader approach is correct, I'll use that (I discovered it after writing the previous message).

i can not tell you if transfer bt 2020 is brighter than 120 nit or if kodi just supports SDR -> HDR conversation or if the wiki is correct with this is watch on bt 1886 calibrated devices (gamma 2.4 120 nits).
under the current information on the wiki it is plain SDR.

there are spec and they are very easy to follow especially with a meter and a spec like PQ.

should be but i will not try it... because limited range on a video renderer on the desktop side is just dumb maybe with a black hole TV this changes.

Using mkvtoolnix I tested remuxing the "non working" files, changing the "Transfer Characteristics"value in the header from 14 to 18. That makes it HLG, according to Mediainfo. And it appears to be working just fine (visually, that is).

Which leads me to believe the problem was probably just in the muxing process for whomever encoded those files.

Are there any oneVPL implementations on Windows?

[shaolin95]

Hi guys!
Has anyone seeing a non linear stretch shader like this
https://www.heimkinoverein.de/forum/...inear-stretch/
For MPC?
Thanks

[v0lt]

@shaolin95
MPC shaders do not change the frame size.

[huhn]

you don't need to change the size the output can be forced to be the same size.
you just distort it and that should work shouldn't it?

Not looking promising?
I started looking into mpv but boy is not very user friendly lol

[Enet47]

I recently tried mpc-be again and I really like it. There isn't such a large difference as maybe there once was in picture quality between mpv and mpc-be. I watch a lot of 3D and I convert them to TB for a couple of reasons. But until I've converted them, mpc-be is still the best way to watch them.

Yeah I know what you mean. I did a crap ton of reading and testing to get my script where it is today and I know that I've only scratched the surface lol. You can look at mpv as a kind of a non-GUI version of mpc-be+madVR. But with added flexibility because of a large open-source library of scripts, code and shaders which is why I've come to love it. That flexibility comes at the cost of increased configuration complexity, but you can use an mpv GUI then slowly work towards a fully text based config.

In the mean time, I think mpc-be is the best direct-show player and is the only other player I have on my PC.


BTW, thanks for the non-linear stretch, I've never heard of that before but it did look interesting. I tried it on video and it's horrible which makes sense, so I modified my config to only run the script for images. It works ok but not for all images. It's a bit of a hack and the author says he doesn't see the point. of it. Like the author I can't see the point of ever using it.
