AV1 codec to open video using Avisynth and  Virtualdub Empty AV1 codec to open video using Avisynth and Virtualdub

Hi.

I'm trying to open video AV1 encoded with Virtualdub. For this, I'd write a Avisynth script.
But I cannot set my system (still Windows 7 -SP1) to set correctly DirectShow to recognize AV1 codec.

I also tried ffms2 and LSMASH library without success.

Any ideas?

Use latest FFmpegSource that includes libdav1d:

That is all the help I can give.

Thank you, Admin.

I copied this to Avisynth folders.
ffms2.dll
ffms2.lib
ffmsindex.exe

With this,
Code:
v1=FFVideoSource("video.mkv")

or this:

Code:
v1=ffms2_FFVideoSource("video.mkv")

I get this error:

Code:
No video track found

But it creates video.ffindex file.


If I use other version of ffmpeg, I get this error:

Code:
Script error: There is no function named FFVideoSource
or
Code:
Script error: There is no function named ffms2_FFVideoSource



With this:
Code:
v1=DirectShowSource("video.mkv")

I get no error, but this message:
Code:
No video



I copied LSMASHSource.dll to Avisynth folders.

If I load it in the script,
Code:
LoadPlugin("C:\Program Files (x86)\AviSynth\plugins\LSMASHSource.dll"

I get:

Code:
Unable to load plugin error 0xc1

If I don't load, I get this:
Code:
Script error: There is no function named WLibavVideoSource

Error 0xC1 means that you are mixing 32-bit and 64-bit components. Everything must be same bitness.

I can not provide any further help. I don't use Avisynth.

Many thanks, Admin.
Your attention and responses were appreciated.

I could solve the problem.
Installing and using Avisynth info tool, I could see that after a system restore, my Microsoft Visual C++ was a real mess.

Reinstalling Microsoft Visual C++ 2015, 2017 and 2019, all problems had gone.

Thank you.

Very Happy
