How to Run Avisynth Script from FFmpeg?

[nothingnew]

Hello,

I've been trying to run avisynth script from FFmpeg, but failed all the times.

I've tried to use both FFmpeg 32-bits & 64-bits, and also the solution from this link, but it's still not working.

https://stackoverflow.com/questions/29342030/error-using-avisynth-script-as-input-to-ffmpeg

Can anyone suggest the solution?

Thank you

That's how you do it, "ffmpeg -i script.avs...". What does your script look like? Have you installed AviSynth? Can you open the script with some other program like VirtualDub?

[nothingnew]

Yes, I already installed Avisynth. This is how the script look like:

# Source file
AviSource("colorbands_original.avi")
# Convert to YV12 (4:2:0) using the BT.709 matrix
ConvertToYV12(matrix="Rec709")

Can't open it using VirtualDub as well

If you google "virtualdub 80040154" you'll find lots of references to that error. Do you have a VFW decoder for the codec used in the AVI file? What does MediaInfo say about the AVI file?

Also, try creating a script with just:

Version()

Can you open that in VirtualDub. That will at least verify that AviSynth is installed.

Test both VirtualDub 32 bit as well as 64 bit (like you did for ffmpeg).

Version()

This code produces the same error. Let me try to reinstall my avisynth again.

Test both VirtualDub 32 bit as well as 64 bit (like you did for ffmpeg).

It works in VirtualDub 32.



But my script doesn't works...



This is what MediaInfo says:



I install Ut Video Codec and now it works in VirtualDub. Will try it in FFmpeg.

Still doesn't work with both FFmpeg 32 or 64-bit

Is it a different error message in ffmpeg ? if so, what is it ?

When you open the 32bit avs in 32bit vdub, what does file=>file information say in vdub ?

[nothingnew]

It's this error.

File information:

Are you sure that's ffmpeg 32bit binary?

Post your full ffmpeg commandline, it looks cut off in the screenshot. Just copy & paste the text, you don't need image screenshot for that

I renamed my ffmpeg x86 binary to ffmpeg32 to distinguish from the x64 version ,so you can call it from anywhere without mixing them up

If you just enter

ffmpeg32 -i "colorbands_709_420.avs"

what does ffmpeg say ?

Which file that I can rename? I tried to rename ffmpeg.exe to ffmpeg32.exe and run the code, but it didn't work. Did I rename the wrong file?

[poisondeathray]

That's the same error message you get, when there is a 32bit/64bit mismatch , eg. 64bit ffmpeg with 32bit avisynth, or 32bit ffmpeg with 64bit avisynth

Since 32bit vdub worked, it has to be 32bit avisynth that you have installed . So I would double check your ffmpeg binary to see if it is 32bit.



It could also be a problem with that specific binary; try downloading a different one, maybe older

[nothingnew]

It works!

Thanks for all the helps...

[jagabo]

It works!

What works? Clearly explaining the solution will help the next person with the same problem.

Ah, I'm sorry. So, I rename the FFmpeg 32-bit into ffmpeg32 and put it in the avisynth script's directory. I don't know whether it's the right solution or not, but doing that work in my case.
