AviSynth 3 Script files (.AVS) not supported (ffmpeg library not included)

[thenicnic]

Expected behaviour

AVS3 files (AviSynth Script) can be parsed (codec_id=192).

Actual behaviour

[ERROR:[email protected]] global cap_ffmpeg_impl.hpp:1268 open Could not find decoder for codec_id=192
[ERROR:[email protected]] global cap_ffmpeg_impl.hpp:1317 open VIDEOIO/FFMPEG: Failed to initialize VideoCapture

Probably libuavs3d is missing in the included ffmpeg binaries.
Would be great if you could please include it or if anyone could tell me how to do it manually.

Steps to reproduce

v_file = cv2.VideoCapture(file_path, cv2.CAP_FFMPEG)
v_hgt = v_file.get(cv2.CAP_PROP_FRAME_HEIGHT)
v_wdt = v_file.get(cv2.CAP_PROP_FRAME_WIDTH)

Issue submission checklist

• This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
• I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)
• The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")
• I'm using the latest version of opencv-python
