FFMPEG and Avisynth

[fabje]

Is there a way to use an .avs file as an input file for FFMPEG.exe?

I saw this:
Just create an "input.avs" text file with this single line ...
DirectShowSource("C:\path to your file\yourfile.asf")
... and then feed that text file to ffmpeg:
ffmpeg -i input.avs

Here: http://www.ffmpeg.org/faq.html#How-can-I-read-DirectShow-files_003f

But when I try that I get this error: Unknown error occurred.

I have this in my input.avs:
DirectShowSource("D:\source.ts")

Anyone that can help?

Yes you can if your ffmpeg.exe binary has been compiled with avisynth support

First, debug your avs script. Does it open in vdub or avspmod, and post any error messages

When I use VirtualDubMod and open the .avs file I don't get any errors.

This is ffmpeg.exe with loglevel on debug:
D:\>ffmpeg.exe -i D:\input.avs -vcodec libx264 D:\test.mkv -loglevel debug

What version(s) of AviSynth, DirectShowSource, and the decoding filters (ffdshow or LAV Filters)? Do you have the proper MSVC runtimes installed?

Although really, you should probably be using LSMASHSource to open TS files (or remux to MKV with mkvmerge and use FFMS2), not DirectShowSource.

Also, it'd be more accurate to test if x264.exe works with the script, because like x264, FFmpeg talks directly to the AviSynth library.
