[BUG] Problem with Hybrid_dev_2026.02.28-13831

[Miranda]

I've just installed on my Windows 10 PC and I'm getting errors when trying to process an MKV rip of a DVD file.

The procedure entry point_CxxFrameHandler4 could not be located in the dynamic link library C:\Program Files\Hybrid\64bit\Avisynth\avisynthPlugins\d3d9.dll

and:

AV1 is only allowed as raw or inside a mkv, mp4 or webm container!

---

Also I tried Vapoursynth, and when clicking preview I get "REMOVING RVRT" - the preview window now opens, but it is grey.

And now Hybrid isn't opening at all. It gets as far as "Updating tool versions" and then fails to open.

---

I uninstalled the dev version and installed Hybrid_2025.11.09.1_SETUP, but I'm still getting Exit1 crashes. What could have changed?

When switching versions make sure to uninstall the old version completly.

Also I tried Vapoursynth, and when clicking preview I get "REMOVING RVRT" - the preview window now opens, but it is grey.

Strange, there is only:

sendMessage(HCONSOLE, FOURSPACE + "REMOVING RVRT" );

That is some debug output I forgot to remove which shouldn't cause issues. (and only should be annoying => looking into it => Hybrid_dev_2026.02.28-181813 should be up in a few minutes)

AV1 is only allowed as raw or inside a mkv, mp4 or webm container!

As far as I know, this is correct. mov does not support av1.

The procedure entry point_CxxFrameHandler4 could not be located in the dynamic link library C:\Program Files\Hybrid\64bit\Avisynth\avisynthPlugins\d3d9.dll

No clue, might be some missing dependency.
Can you check the dll using DependencyWalker?

I'll check the dependanccies tomorrow. 

It's not an av1 file, it's an MKV rip of a PAL DVD.

It's not an av1 file, it's an MKV rip of a PAL DVD.

av1 is a video format,....
Argh, I see the problem:

2026.02.28 - 14:33:09_Windows 10 Version 22H2 (64bit)_2026.02.28.1 - level 9: ProResModel get->found no field 'codec'
2026.02.28 - 14:33:09_Windows 10 Version 22H2 (64bit)_2026.02.28.1 - level 9: AV1 is only allowed as raw or inside a mkv, mp4 or webm container!

=> Hybrid assumes av1 encoding is used, but you selected ProRes

[Selur]

Uploaded a new dev (Hybrid_dev_2026.02.28-195429) which should fix that.
(It was a typo, that was added when I added support for VCEEncC AV1 support.)

[Miranda]

Thanks. I guess I'll still have the missing dependency problem - not sure what's causing that after a clean install.

Which file do I need to open with Dependency Walker?

Attached is saved from opening Hybrid.

[Selur]

Which file do I need to open with Dependency Walker?

I would look at:

C:\Program Files\Hybrid\64bit\Avisynth\avisynthPlugins\d3d9.dll

try whether installing: Microsoft Visual C++ 2015–2022 Redistributable (x64) helps,..

"Hybrid.dwi-28.02.2026.zip " <- Hybrid starts, so this is useless,...

[Miranda]

Attached. This is from the Hybrid_2025.11.09.1_SETUP install.

[Selur]

Okay, so if I load your dwi here everything ahas a question mark at it, so that does not help me.
My guess atm is that either:
a. you are missing some runtime
b. you are missing direct X dependency or similar
since it works here and I have not changed anything around Avisynth++ for 2 years or so something must be missing on your system.
d3d is a Direct3D runtime file that is needed for FF3DFilterGPU.

Ps.: going to bed now.

It's strange, Hybrid was working fine untill I updated to the latest dev version. I'm using the same PC and I haven't changed anything except Hybrid itself. Even going back to an older version of Hybrid now will not work, so perhaps the installation of the latet dev version removed some files?
