cannot load plugin using ffmpeg ladspa about noise-suppression-for-voice HOT 7 CLOSED

Removing the *.so file extension worked. I did not follow the meaning of your instruction to use the proper suffix for x64. I am on x64 and the following worked for me.

INPUT=/data/sample_car.wav
OUTPUT=/data/sample_car.nsfv.wav
docker run \
  --mount type=bind,src=$(pwd),dst=/data \
  denoise \
  "ffmpeg -hide_banner -i $INPUT -af ladspa=file=librnnoise_ladspa:plugin=noise_suppressor_stereo $OUTPUT"

And for the benefit of others who are not going through a docker container, the command would be.

ffmpeg -hide_banner -i $INPUT -af ladspa=file=librnnoise_ladspa:plugin=noise_suppressor_stereo $OUTPUT

Thank you all for your help.

I'll try to check later what's going wrong there.

Also, I have never really deployed a LADSPA plugin before, and it is possible that I have done it incorrectly. I got rid of the LADSPA_PATH and I put a single file from your build output here: /usr/local/lib/ladspa/librnnoise_ladspa.so (which is apparently the default place to look).

That doesn't work either. Maybe I am missing a configuration step or something.

Your command incarnation is simply wrong, : separates options.
Correct syntax is:
-af ladspa=file=librnnoise_ladspa.so:plugin=noise_suppressor_stereo

@richardpl Thank you for your suggestion. Unfortunately I tried using the colon and I got the same error.

I am providing docker instructions for perfect reproducability.

Remove ".so" it is not needed.

Also if you are on x64 you need to use proper suffix.

Yep, .so is not needed, I've tested and without it ffmpeg sees plugin and does its work.
