Ok. If you want me to try out some test builds with some extended logging, so perhaps it can be easier to see what is going wrong, then I can do that for you.

On a related note: Have you considered using DXVA decoding of MVC content? Maybe that will solve the problem, and also remove the dependency on the Intel SDK, for those with a GPU capable of decoding MVC.

DXVA decoding basically requires having a software decoder for MVC (because a lot of stuff still needs to be handled in software), so until such a time when FFmpeg adds MVC decoding, unfortunately using DXVA for that is not easily possible.

MPLS angles support

@nevcairiel: In case you missed my earlier post, could I get a yes or no on this feature request quoted below? Thanks.

I've just purchased a bunch of GKIDS BD's that uses the MPLS angle feature to differentiate between credit sequences. As of now I'm forced to watch them with English credits, but I'd strongly prefer the original Japanese credits. Very frustrating.

I've tried using the modded mpc-hc with dslibbluray (with madvr, navigating blindly through the BD menu), but the subtitles seems to have a life of their own. They don't follow the timecode. I've tried both XYsub and the built in subs renderer.
I've also tried using the seamless playback function in Potplayer by adding each corresponding m2ts file the playlist, but with this method there's loads of audio glitches/skippings and the audio always gets out of sync, regardless of which audio decoder/renderer I use.

Is there any other method I can use if madvr is mandatory? Ripping is not an option.

This is completely different from multi-angle video streams.

This is not hugely important and might not even be on the agenda of the LAV developers, but maybe its easy to implement. And even if not, then i hope its still interesting to see that such mpls files exist.

With "Grand Budapest Hotel" it would not involve much guessing as the first localized titlecard appears right after the credit sequence.

Anyhow - it's not a "crucial" feature or anything. But as LAV opens mpls files it would be nice if it also supported this feature. And as you are aware now (or have been all along) that these files exist my mission is complete - the rest it up to your judgement, mood and time.

I don't have any plans to do that anytime soon. I don't believe I even have any disc which uses that. Most discs with localized video I have seen used different titles instead of Angles.

I could reproduce the problem on a disc with an Intel GPU, unfortunately it appears to be a long-standing Intel issue that can result in the GPU reporting a "busy" state infinitely, causing decoding to just die. So for the time being, i've turned off hardware accelerated decoding again.

Ok thanks. I will test it as soon as the next nightly is up.

Yes I know. I have a large Bluray library and these from GKIDS are the first ones I've come across that uses this feature. Unfortunately I've already purchased 14 of them. I suppose the only solution right now is to rip all the corresponding mt2s into a single MKV. It just feels wrong seeing names like Gillian Anderson and the Fanning sisters in the credits of a Studio Ghibli film.

Does anyone know of any other solution? My only requirement is madvr.

Next version will have (limited) UltraHD Blu-ray support. You can already test it if you install the nightly build.

Hi nevcairiel!

1. D3D11 doesn't work with the nVidia Optimus on Intel GPU if in the control panel nVidia selected GPU nVidia.
http://i99.fastpic.ru/big/2018/0117/...fb41dc2bf4.jpg
DXVA Checker shows that d3d11 enable on Intel GPU if in the control panel nvidia selected GPU nVidia.

2. nVidia CUVID doesn't work with the nVidia Optimus if in the control panel nvidia selected any GPU.

3. After install LAV 0.70.2.88 mvc (software mode) doesn't work with the nVidia Optimus if in the control panel nvidia selected any GPU.

Windows 10 1709, Intel i5-4200M, Intel(R) HD Graphics 4600 (20.19.15.4835), NVIDIA GeForce 840M (23.21.13.9065)

Optimus is generally just not supported. Use it at your own discression, but don't expect anything to work. I do not provide support for such setups because they are impossible.

madVR works great with Optimus, but only in 2D
On Intel GPU - 3D is slide show and later crush Intel driver.
On nVidia GPU - 3D doesn't work.
madVR or LAV Filters bugs?

Wish I could use Optimus too...

LAV has no control over what hardware is available. It'll just try to use it. If its unavailable due to Optimus, there is nothing I can do about that.
Just leave DXVA2-CB or D3D11 in "auto" mode and let it pick the device, it'll try to find one that works, I hope.

I have optimus, too, and I can get it to work well enough for 2D. It's not a well implemented technology so any issues you have with it are not going to be things LAV and madvr are going to solve. Bug MS, nVidia, and Intel.

Only on Intel GPU works (if in the nVidia control panel selected Intel GPU).
But Intel GPU is slow for madVR

The first way is like you said, an mkv. With my chapterEditor is it an easy task and should be done in less then 15min(depend on your hardware).

The second way: You can manipulate the mpls with BDEdit. Make a copy before!

Multi-Angle mpls works similar to Multi-Edition BDs, different m2ts files are used for different Angles/Editions.
Find out which m2ts files belongs to the Angle you want.
I'm not an expert in BDEdit but it should be possible to change the "main" playlist of an Angle-mpls.
