Will be fixed in today's nightly. And I made sure it won't fail again if new decoders are added.

Yes it failed because of this issue with MSBuild https://github.com/Microsoft/msbuild/issues/2424 . And there were other issues needed to be fixed so the nightly were frozen. Will be build normally today.

If that helps in any way, I've noticed with Process Explorer that whenever I try to open an x264 file, I can see a second mpc-hc64.exe item suddenly appearing in the process list, which is marked "Suspended" and stays idle. Then after 5-10 seconds delay, it disappears from the process list, at the exact same time the video is finally playing, see http://i.imgur.com/qKDFwy3.png

Can you please try latest development version http://nightly.mpc-hc.org/ (should be available in an hour, or you can try previous one from old directory). There were reports (https://forum.doom9.org/showpost.php...postcount=3192) that it is fixed. Probably by using new non-xp toolchain. Still it is Windows bug, but if it persist on latest nightly we will try to resolve/workaround it.

ParkerLewis · 15th August 2017, 23:04

I will try that tomorrow (going to bed now), thanks a lot. But if it's related to MPC-HC startup time and Windows Insider, I doubt it will be fixed for me, as :

- I'm NOT on Windows Insider
- The issue I'm encountering is NOT a startup / app launch issue : MPC-HC itself launches immediately as always. It's a "on file open" issue, with x264 files.

kasper93 · 15th August 2017, 23:06

Ok, so this change a lot. Can you also try disabling H/W decoding in LAV Video decoder settings? If nothing help we will diagnose what cause the slowdown.

EDIT: I can't read...

sneaker_ger · 15th August 2017, 23:12

He already tried without H/W.

Does it matter which renderer(s) you choose?

Yeah, I tried that... "Hardware decoder to use" => tried putting it to "None", but didn't change anything unfortunately.

Duh, I hadn't even tried that, sorry. I had CoreAVC Video renderer selected as an external filter. Worked like a charm for like six years or so. Deactivating it now... problem solved.

I wonder what might have caused this problem though. Anyway, in 2017, CoreAVC might be useless now, isn't it ? Looks like it's dead anyway. Is there any reason to use an external AVC decoder anymore or can I just uninstall it and forget about it ?

Thanks !

sneaker_ger · 15th August 2017, 23:28

Uninstall and forget CoreAVC.

Megalith · 16th August 2017, 02:29

Were any changes made to the Internal Audio Renderer in the latest Nightly? In Exclusive Mode, the audio eventually gets a static-like distortion if I seek to different parts of a video. I never had this issue in past versions.

There is still much to improve there. But I'd like to prioritize changes based on real life samples, so if you have some samples that MPC-HC struggle with please share it.

Nice. Thanks for sample. I will work at it next weekend. Should be able to squeeze some performance in this area.

DXVA doesn't play this sample. Probably Microsoft's decoder initialize DXVA and fallback when it fails. That's why we detect it as being active for a while. But I haven't look in detail what's going on in the code. But I doubt we can change anything here.

rock · 17th August 2017, 05:54

hi, I just found something more strange. When play h264 10 bit (sample from sneaker_ger) with MS decoder, which is actually not playable, but statusbar shows H/W.

LigH · 17th August 2017, 07:26

So, the decoder tries to work in hardware accelerated mode, fails (which was expected), but does not fall back to software decoding (which would be expected)?

Aleksoid1978 · 17th August 2017, 08:59

MS decoder can't detect that H.264 stream is compatible with DXVA and trying decode ))

nijiko · 18th August 2017, 12:32

Are 60,65,89 and later no longer support for XP?

sneaker_ger · 18th August 2017, 13:17

Correct. XP support has been dropped for good.

madshi · 19th August 2017, 10:40

@devs,

not sure if you're interested in this, but the latest LAV + madVR builds now support native D3D11 DXVA decoding, by using a new custom interface. IMHO going forward, this is going to be the best solution for hardware decoding. It performs slightly faster than DXVA2, has identical image quality to software decoding (unlike DXVA2), and due to the simplified custom interface might hopefully also be more stable/reliable than native DXVA2 decoding. Current disadvantages of D3D11 DXVA decoding are that it won't ever work on anything older than Windows 8.1, and that the current madVR version doesn't support DXVA deinterlacing + scaling yet (will be added in a future version), when using native D3D11 DXVA decoding.

If you're interested in adding support for this to your renderers, you can see the new custom interface here:

https://github.com/Nevcairiel/LAVFil...onfiguration.h

To be honest, I'm not sure how difficult it would be to add support for this to EVR, and whether you find it worth the effort. Just wanted to let you know.

I'm still using Win7. Will this new version 0.92.1 improve anything vs previous release 0.91.11?
I don't use 3D. I'm very pleased with my current setup and thinking, "If it ain't broke, don't fix it".
