Subtitle issue (3 Viewers)

[Rick164]

That's odd, using it with CUVID myself (latest LAV + xy-VSfilter) but will see if I can test that as well.
Do have it running on my brothers setup with DXVA2 (native) which still has a LAV version from a few months ago where it runs fine with BR-Disks and MKV embedded subtitles at least.

Yep with CUVID, the GPU is used but if we set DXVA, i think it's goes to CPU with vsfilter
Latest master LAV give the same result, so it can be an issue with MPC Engine too, because other m2ts + pgs subtitle are ok, also MKV with PGS sub.

Just to be perfectly clear: I'm using DXVA, MPC engine and the latest LAV.
But this issue happens ONLY with the first season of the TV-series "The Americans" and NOTHING else. I have a thousand BD's and hundreds of TV-series. NONE of them shows this issue, only "The Americans". So I suspect this series. Thing is, I don't find anything strange about it and it works perfectly in other players. So if you guys test something it should be with this specific series.

The only difference could be the used subtitle engine between the external players, if it doesn't show up with DirectVobSub as well it's most likely that for this series it's either non-standard or made for more recent subtitle engine (incompatible markup).
xy-VSfilter does have the benefit of having high quality subtitles + lower resource usage and active development however if it means losing DXVA then for most machines it will probably affect performance too much.

@Sebastiii Just tested DirectVobSub (xy-VSfilter) with DXVA and enabled the LAV tray icon to easily check however remember that tray icon changing colors (and mouse over text) depending on DXVA/CUVID but that isn't working anymore, do you know how I can check if DXVA is still being utilized?

 

[Sebastiii]

I will try to extract a sample
xy-VSfilter works on that sample (MPCHC Engine not)

DXVA, i can see it by CPU usage if it's off, normally with LAV Video decoder if we set DXVA, we should see that it fall back to non dxva. I will try to screenshot that

MPC-HC Engine : (Active so DXVA in use)

xy-VSfilter : (Available is describe so no DXVA in use) (CPU usage is high too)

I've reported this bug already 1,5 years ago, unfortunately i never found a solution -> Link (sorry, its a team internal link) And there is another thread -> Link. So i think it is a confirmed bug, but i don't know, if it is a bug from MediaPortal or LAV?

With Zoom Player it works with LAV + DirectVobSub (xy-VSfilter) but not correctly with MPC engine so suspect either the combination with LAV or that some content (subtitle markup) isn't compatible with MPC.
Did notice that LAV 0.66 has an VC-1 (WMV) seek bug where it has trouble with skipping (long delays) so went back to 0.65.

Made a few test more. Unfortunately a lot of subs aren't working propper in MP, please take alook at the screenshots ->
Settings MediaPortal:

Result MediaPortal:


Playback the same sequence in MPC-HC:


LAV Splitter settings are the same in MPC-HC and MediaPortal:


It would be great, if we could find a solutions for this!
