So you saying there is absolutely no way for it to be used in other software as a decoder? it seems to do very well with Windows Media Player, being able to play non-standard files with subs with a restrictive player is pretty awesome!

Its a DirectShow filter, it can be used in any software which uses DirectShow for video decoding - which WMP is one of. Software which doesn't use DirectShow also cannot use a DirectShow filter. See how that works?

Hahaha... after all testing various settings and searching for a solution it all comes down to this...

• Display Subtitles on Overlay/VMR/EVR Surface

F*** me...

https://frupic.frubar.net/shots/36373.png

Subtitles are now showing perfectly in PotPlayer!! LAV Filters working! All is good! Perseverance furthers...

Edit:
I'm lost... now what to do...? :/

Here is PotPlayer fullscreen where LAV and showing subs work:
https://frupic.frubar.net/shots/36381.png
The subs look really bad.

Here is PotPlayer fullscreen without LAV:
https://frupic.frubar.net/shots/36382.png
The subs look great.

Question:

The Vulkan API can be adopted for video decoding like D3D11 or OpenGL?

Vulkan has no benefits for video decoding. Neither does OpenGL.

I beg to add WEBVTT subtitles support in LAV Filters. More and more YT videos have subtitles and it would be nice to play the videofile with subtitles of this kind. If you are interested and need a sample, let me know.

Are you sure that it is LAV Filters (and not your subtitle renderer or something else) that needs to be updated for this? Because if I look at the input formats that LAV Splitter handles I see webvtt among them.

In what form do you have them, anyways? Just a raw file on the HDD, trying via http or muxed in a container?

There is still no subtitle renderer which even remotely supports any WebVTT features, so any such endavour would be rather fruitless.
I could add it, but then nothing would show it. Yay? Guess its not my problem anymore then =p

What subtitle renderer is actively developed nowadays? Asking their Devs doesn‘t hurt.

Win8.1x64, Kaby Lake i5 7200U/HD620 : 3D-MVC-mkv

I tried the nightly .88. Unfortunately now I have a picture in the "black-screen-movies" of before but they are now jerky and also those who worked with .83 are jerky too…
Went back to .83…..
Maybe there is a way to override the “busy” flag of the hardware?....
(samples of working/not working movies are still available for download via PM link I have sent you)

I flashed back an image from 8/2017 of a Win10x64 setup on this machine. Upgraded to Intel-driver .4901 (new style) and downgraded later to .4849 (old style).
LAV .88 played with both drivers with "LAV Hardware decoding" "None" and "D3D11" both types of MVC-files.
(the shut down of the player MPC-BE was with the difficult files a little bit tricky but in the end possible.)
LAV .83 played the good files without Problems (with both drivers), the bad ones gave a black screen, like in Win8.1x64.

In the Win8.1x64 setup I'm using .4860, which is in between the 4849 and the 4901, still LAV .88 does not work.

That tells me that my hardware is not "too weak", but the software has an issue... driver mainly but to some extend also the decoder and OS are involved.
I would hate to be forced to move back to Win10 because this system is constantly doing things behind my back I don't want...
On top comes that Madshi is advertising Win8.1 as the prefered media system. It would be a pity if modern CPU/Graphics like Kaby Lake would not be fully suported in Win8.1.

The hardware decoding option has no impact on MVC decoding, it was always used when appropriate hardware was present, so your testing does not tell you what you think it tells you.
Anyhow as mentioned before, I do not have enough spare time right now to waste on trying to figure out whats wrong with weird Intel GPUs. So I will not work on this further. It functions now exactly like it did for all LAV releases before.

PS:
Intel/Microsoft does in fact only officially support Kaby Lake on Windows 10.

...it still stands : LAV .88 decodes both file-types ok, so the Hardware is not the problem...

So everything is fine then. LAV decodes the files properly, and thats that.

Software decoding is independent of the OS you use, or the drivers you have installed, so if you're seeing issues on one OS and not on another, its far more likely that this is caused by the rendering - which is outside of LAVs control.
As a test, you should run it in SBS mode instead of frame-packed 3D, this avoids a lot of weirdness with 3D in the drivers, and could point you into the direction of whats going on.

PS:
You should really not speculate about peoples motivations. It'll only result in people getting pissed off and ignoring you in the future. Just sayin'
I didn't even like 3D before I ever implemented 3D MVC decoding, and yet its still something that exists. Weird, huh?

the parsing of the ISO BDUHD with the LAV splitter unfortunately still does not work, will it be usable with the stable version?

How exactly does it "not work", can you provide useful details to tighten the scope?

From what I'm told from other users, the latest nightlies should be working fine for UHD BD.

Yes works great. The only thing not working (at least with JRiver) is that there is no title selection.

Does it make sense to ask the devs of this project for WEBVTT?
