The internal subtitle renderer refuses to find the corresponding subtitle in customized folder starting with the new 1.8.0 release now. Can someone confirm there's a bug?

I do not confirm. Subtitles from the "subtitles" folder open automatically for me.
You can also read the wiki (https://github.com/Aleksoid1978/MPC-BE/wiki/Automatic-loading-of-external-tracks).

In my case, the subtitle files are in an extra folder I created in D:\Subtitles, previous versions definitely worked. I didn't change the settings before upgrading.

@Anima123
Show your "Autoload paths" for external subtitles. By default, there are only relative paths.

It is ".;.\subtitles;.\subs;.\*sub;d:\subtitles".

Ok. I confirm the problem.

Fixed in MPC-BE 1.8.0.3.

I am getting crashes when trying to play FLV1 video codec files. Using 1.8 and latest nightly, tried different renderers too. They play in VLC. Any ideas? Thanks.

I did setup a new PC and unfortunately MPC-BE seem to be not "finding" the Realtek analogue sound output. Can anyone confirm ?
Tested MPC-HC with SaneAR renderer and there it works !

@devs. Follow up: This problem seem to affect basic audio-out-setup. Both normal and dual-audio !! MPCAudioRenderer works fine.

[huhn]

sanear has an option to select the output default DS has not.
the default DS will also not work when the sample rate is over 192khz.

clearly shown here:

Made more tests regarding my sound problem posted in #10761.

MPC-HC:
Without SaneAR it does not connect to the Realtek analogues out too but it seem to fall back to HDMI-audio so that it least plays with some sound while BE just play silently !!

VLC: No problems.

MPV-NET: No problems

Hope the devs can fix this because dual-audio-out is my prefered configuration.

There's no bug. If you select system audio output and it's not working.

I uninstalled MPC, removed settings, installed fresh and left everything at default. still happening. I have a lot of these files so not a very small issue for me. Is there anything else I can do?

Sometimes I really hate Windows !! After setting the analogue-outs as system default and then switching back to HDMI it is working again as it should.
Thanks for the feedback.

[SirMaster]

Is there any way I can programatically change between the options "Touch Window from Inside" and "Touch Window from Outside"?

I find myself changing these quite often for certain content, especially on an ultra-wide display or projector and I don't see a hotkey or a network command for these options.

Any reason they never got control options for them? Any possibility they could be given a hotkey or network control option?

[huhn]

they are there already.
player -> keys
use the search function and type in outside and inside.
they use the short term "vidfrm" so you may not notice directly.

it has a web interface which allows most stuff too.

btw. the key page is buggy with a german keyboard it shows english keybaord inputs. this is mostly optical because technically it still works.

[SirMaster]

Oh, thanks.

I was searching for "touch" and otherwise not finding them, but I see them now.

[Zulithe]

Confirm.
P.s. Fixed.
Thank you!

All builds crash with the new Windows Update 24h2! It takes ~10 videos to load than crash. Only the compatibility mode to Windows 8 helps... Please fix this.
My Problem is now fixed with the new 1.8.0.7 nightly...
Thanks!

[wyup]

I can also offer such features (and even more). But who will implement this and thoroughly check it? After all, we don’t need to break the existing functionality.
Hi, which tonemapping algorithm does current MPC-VR use, and from which input luminance does it tonemap?
Someone pointed me to the code in the past, but it was a simple function.
Today libplacebo library (https://github.com/Asd-g/avslibplacebo?tab=readme-ov-file#tone-mapping) can use bt2446a (ITU-R Report BT.2446, method A), a more modern algorithm. This library takes input and output luminance for most efficient tonemapping. Output luminance is already in the MPC-VR user interface, but input luminance? It could read from HDR10 metadata (MaxCLL or MaxDML) or be selected in UI.

I know in the past input luminance for MPC-VR HDR > SRD was 10,000 nits, too much, since most HDR is <= 1,000 nits. Custom output nits is nice to have, but also dynamic peak detection by libplacebo would be nice in case of no metadata.

"Simple function" is used.

Your idea is very cool!

[wyup]

Sorry, i didn't use the right words.
I see it's done by pixel shaders (https://github.com/Aleksoid1978/VideoRenderer/blob/master/Shaders/d3d11/ps_convert_pq_to_sdr.hlsl).
I see it is using 'hable (https://github.com/Aleksoid1978/VideoRenderer/blob/master/Shaders/convert/hdr_tone_mapping.hlsl)' algorithm.
However, is input target luminance hardcoded at 10,000 (https://github.com/clsid2/MPCVideoRenderer/commit/3c065ed75eb71728a5302e3aa50fb1feddbfe4e9#diff-29efc76f42f1606f46a9652c964392e027d4b9aaaa68968ed951e0c59569a067R873)? This is not efficient. It should only compress content brightness range (0.005 nits - MaxCLL or MaxDML).
There should be a UI option box to manually enter, as there is for SDR nits, or take it from MaxCLL or MaxDML from HDR10 metadata.

Please - the code is open, you can implement the wishes or ask someone who can, make a pull request.

Otherwise, it turns out that we want everything, but no one wants to do it themselves :)

[clsid]

First step would be to make MaxCLL (or 10000 if unknown) available to the shader as a parameter.
Second step would be to adjust the shader algo to use it.

I can help with second step.

You can hardcoded value from MaxCLL from file and compare result.

[huhn]

the newer version has no "maxcll" anymore in the shader so you can not just change the value as easily as before.

i guess it is now part of "float LuminanceScale;" where ever that is.

i still have code from version ~0.6 around and changed
#define SRC_LUMINANCE_PEAK 10000.0
to
#define SRC_LUMINANCE_PEAK 1000.0
it doesn't have the wanted effect:

edit: left 1000 right 10000(original code)

This is probably due to the algorithm used (I don't know if it's 'hable' or bt2446a). I would recommend using bt2390 with the original roll-off even though it's older, as it produces the best results in this regard. Using 1000 nits as the default MaxCLL makes more sense than 10000, even though that implies clipping depending on the source.

But then this is all subjective, 'hable' may produce decent results, I'm too lazy to start testing again.

[huhn]

it throws normilized to 1 pixels and 125/10000 at this code:
static const float ST2084_m1 = 2610.0f / (4096.0f * 4.0f);
static const float ST2084_m2 = (2523.0f / 4096.0f) * 128.0f;
static const float ST2084_c1 = 3424.0f / 4096.0f;
static const float ST2084_c2 = (2413.0f / 4096.0f) * 32.0f;
static const float ST2084_c3 = (2392.0f / 4096.0f) * 32.0f;

#pragma warning(disable: 3571)

inline float4 ST2084ToLinear(float4 rgb, float factor)
{
rgb = pow(rgb, 1.0 / ST2084_m2);
rgb = max(rgb - ST2084_c1, 0.0) / (ST2084_c2 - ST2084_c3 * rgb);
rgb = pow(rgb, 1.0 / ST2084_m1);
rgb *= factor;
return rgb;
}

and the only thing i can say to this is alrighty than.

so the number is only used in the part where it produces "linear light" and does more than this.

[clsid]

You need to compare it with other hable implementations. MPCVR has some simplifications, like in "ToneMappingHable". I remember seeing a luminance related parameter being used there in another implementation. And VLC uses a different constant (https://github.com/videolan/vlc/blob/master/modules/video_output/win32/d3d_dynamic_shader.c#L169) value (maybe due to other differences) (and this value looks worse when used in MPCVR without any other changes).

that's far outside my abilities. we currently give the hable a different data depending on peak nit and max nit so i don't even understand how this is linear it is already kind of tone mapped here. the vlc code seem to just multiply the normalized to 1 back to 10000 while the mpcVR code using 125 multiplies by 80.

i mean is this code really doing linear? i was under the impression PQ is just rescaled binary to 5000. or with other words each value has double the brightness.

this only made me angry because i had to read stuff like this yet again:
#elif (SRC_TO_LINEAR==SRC_TRANSFER_709)\n\
return pow(rgb, 1.0 / 0.45);\n\
#elif (SRC_TO_LINEAR==SRC_TRANSFER_SRGB)\n\
return pow(rgb, 2.2);\n\

when the BT709 is closer to sRGB than the sRGB one...

[Grimsdyke]

@devs. I am now in the final stages of finetuning my new htpc and I ran into an issue that I already had years ago and this reminded me why dual-audio-out
is my prefered setup ! I may have already reported this back then, if so - sorry - but it seem to have not been fixed either.

On a few UHDs - maybe caused by a layer break- the MPC-Audio-Renderer seem to struggle and madVR's "clock deviation" increases from usually around 0.000xx
to very high numbers.
- Using "Event" in the settings at least the film keeps playing but it looks like as if a few frames are dropped and the performance increases again after a while.
- Using "Push" causes a complete slide-show with only noise coming from the speakers.

No problems with dual audio-out !
Also MPC-HC using Sanear audio renderer plays these discs just fine. So I think there might be something wrong. Would be happy to try any test build !!

[v0lt]

@Grimsdyke
1. Do not use two copies of MPC Audio Renderer for dual audio output.
2. Try using DirectSound dual audio output.

[Grimsdyke]

Yes, should have been more precise - "Directsound dual audio out" is when everything works !!

The problem occurs only when mpc audio renderer is active. And I use only one instance of it, of course. Dual audio not even activated then.

[v0lt]

I don't have this problem. I use default audio renderer settings (Shared, Event, 50 ms). Audio device is integrated Realtek sound card or HDMI display.
Yes, should have been more precise - "Directsound dual audio out" is when everything works !!
Use DirectSound.

[Grimsdyke]

This happens only on a few UHDs that I own and so it would be difficult to re-produce for you.
I think it happens both on shared and exclusive - if not, I will report back.

Update,
Both shared and exclusive are having this problem. If you have a debugger or something like that I'd be happy to test.

[huhn]

maybe a bit streaming limitation.
i can not test this at all so i don't even know if bitstream is allowed at all.

but it would explain the some file issue.

[Grimsdyke]

You don't think it could be a layer break issue ?? I mean, it happens always in the same moment in the movies.

Follow up.: O.K., one last round of testing because it is getting late :D
Huhn's comment made me thinking, so I looked at the other possible settings in MPC audio renderer and after activating
the last one: "Don't fill channels when upmixing" the movie plays fine.

So the problem seem to be somewhere in this function ?

O.K., made more tests in the last two days with other affected UHDs and unfortunately activating "don't fill channels when upmixing" does not work on all discs.
Don't know if the devs want to fix this bug ? Would be happy to test & help !! Maybe a bigger buffer might already improve things ?

Will use Sanear audio renderer from now on until this is fixed.
