Nice contribute results please to the Decoder Thread, we know some stuff from Reviews already but it's always good to have more input data, especialy since the driver changed especialy in the power efficiency domain and those changes never have been taken into account yet by reviewers

Can you decode this at 60fps ?

According to the Reviewer Data the current UVD Core used shouldn't have enough Performance reserves todo it

based on that Data i would say it would be nice allready to reach 30 fps

I have a problem using LAV splitter in MPC-BE. I have a line to only show forced English subtitles.

Code:
eng:eng|f;eng:off;*:eng;*:*
But it is being ignored in MPC-BE. Subtitles continue showing for every video with subtitles even if it's English language audio and English language subs. It works correctly in MPC-HC but I have other issues with that player so wanted to use MPC-BE instead.

LAV splitter is set to high priority and is definitely being loaded as I can see/use it in the system tray.

Some players simply override the stream choices, check its settings for anything related to that.

Wow! Fast reply!

I have but can't find anything in there regarding it. In MPC-HC there is an option 'Prefer forced and/or default subtitle tracks' which does not exist in BE. I am not sure if that is anything to do with why it works in one and not the other?

LAV can only do an initial selection of streams, if the player then decides to select different streams, its not something LAV has any control over. So it absolutely depends on the player, if it honors the splitters choices or just does its own selection. Different players, different behavior.

OK thanks. I will have to ask in the BE player thread then.

Soory nevcairiel for being of topic but some RX 4xx users are here.

Did some RX 460,470 480 user tried if Strongene Lentoids Hybrid OpenCL Decoder still works, as each IDCT,MC and PP part is generation individually optimized and chosen at runtime i wonder if it still works @ all on Polaris GCN 4.0 supporting the Decoding or fails or if it's going to fallback to the Tonga\Hawai or some Generic GPU/CPU Path ?

Now it does support — thanks again, Nev

Hopefully we all can do without the Arcsoft DLL, from now on

dxva2 bug with this video and Nvidia graphics

Hello,

I have heavy artifacts if I use dxva2 (native) with my GTX 960 4gb, with Software decoding or QSV it's no problem.

The content is of a TV channel, some of the times its just fine on that channel sometimes I get the artifacts.

Here you can download the sample (is SD and I think H.264): https://www.dropbox.com/s/2zxhgqx2dh...ia_bug.ts?dl=0
Is this a known bug? Is there a workaround? Have others also problems with Nvidia graphics playing this short sample?

If needed I want to make screen record of the artifact...

Thanks and kind regards,
Clemens

the same happens with my 960.

disable SD in hardware acceleration and you should be fine.

I thought only very old ATI cards had that bug with SD H.264 clips.

And ATI has fixed that a long time ago.

And now Nvidia has the same bug ?

Is it only for Maxwell or Pascal too ?

this looks like broadcast. so this could be a simple error in the stream it can't handle.
there could be a bug in lav filter too because CUVID is handling this properly.

there is more than one clip that is know to make trouble with DXVA.

so just lay back and wait. we will see where the real issue comes from.

That file has invalid data at the start. Happens often with recorded .ts files. The software decoder can usually discard that and recover. You will notice black screen first two seconds. Hardware decoding doesn't have good error resilience.

CUVID also fails here (with a pretty old driver version).

Thats not the problem I think, when looking at it live (and much longer) then the same artifacts are there no matter how much I restart the stream. (on that particular channel it isn't a problem all of the time, depends on what they broadcast haven't found a pattern yet).

But its no big deal off course, I can switch hardware decoder to another or turn hardware decoding off for SD. If the bug gets fixed nice if not then no problem, just wanted to report the bug also not quite sure if this is the right place for reporting bugs, if I can do something else please tell.

And thanks for looking at it...seems to be a very nice forum!

Kind regards

Well, FFplay shows errors. You can test for yourself if you want.
