Thankyou for your work!

I would like to mention drawbacks of dropping 32bit:

There are several filters which are only for 32 bit.

If I remember right it is the internal logo filter for 64 bit,
that produces slight false colors ("DeShaker default color").
(shekh once had a look at it, but didn't worked on as it is confusing code).

I don't know if ffmpeg source code would allow to be build as 32 bit?

What does DDL mean? Just a typo of DLL?

PS: I tried to select a video compression and it crashed:

An out-of-bounds memory access (access violation) occurred in module 'VirtualDub64'...
...reading address 00000000A9C072E0...
...while querying video codec "ffdshow Video Codec" (compchoose.cpp:420)...
...while opening video codec with FOURCC "ffds" (compchoose.cpp:528)...
...while enumerating video codecs (compchoose.cpp:515).

There are unofficial builds of FFmpeg. You can look for x86 shared version 6.1.1 there.
But I'm not interested.

Yes. It's a typo.

This doesn't happen to me. I don't have "ffdshow Video Codec".

Are you interested in a crash log? Your repo doesn't seem to have an "issues" page.

It contains an error:

Thread call stack:
Incorrect VirtualDub.vdi file (build 44282) for this version of VirtualDub -- call stack unavailable.

VirtualDub2 x64 build 44282 has no issues enumerating video compressors.

The ffdshow VfW codec is part of ffdshow-tryout rev4531 by e.g. clsid2

https://sourceforge.net/projects/ffd...leases/64-bit/
https://forum.doom9.org/showthread.php?t=120465

P.S.: I believe this problem was introduced between VirtualDub2 x64 ffmpeg6.1.1 test 11 (contains an old EXE from 2020) and 12 (contains a new EXE).

[v0lt]

I installed ffdshow_rev4533_20140929_clsid_x64.exe and during installation I saw a warning about possible crashes.

I also get a crash when ffdshow VFW is installed.

PS: Perhaps the problem with ffdshow VFW appeared after replacing the Windows SDK and other things.

I turned on the "Issues" page and created Issue #1, where I collected various information on this issue.

I hope someone competent can find the real reason, skipping a codec is indeed not a perfect solution.

VirtualDub2 44282 + avlib.vdplugin 0.6.1.70
I decided to re-release the old VirtualDub2 build 44282 with updated avlib.vdplugin 0.6.1.70.

[LigH]

OK, nice, can handle an MP4 with AV1 video from YouTube and use ffvfw codecs.

Please check this version. Will it crash when choosing a video compressor or not?
ffdshow Video Codec (ff_vfw.dll) and Logitech Video (I420) (lvcod64.dll) are not supported.

[LigH]

It does not crash but ffvfw is not listed.

[jpsdr]

That's odd. I've tried the 1rst version of 2.1 on my PC, which have ffdshow 1.3.4533 installed, and it doesn't crash when i choose compressor, and the ffshow codec is listed.

[LigH]

For me it crashed from test12 on, because this included a new EXE built with a more modern MSVS. I guess it might be related to the set and maybe order of VfW codecs being enumerated, but we will need to trace the reason to understand what happens and find a way to avoid it. I hope a test build creating a verbose log of the enumeration loop may help...

Many thanks, v0lt !
As a sidenote: As long as there are classic 32-bit AVS plugins which won't get any update
because stable (or developer had to take on other tasks) it is viable to still have 32-bit applications
like VD2 available, so again thanks if somebody caring for that still.
