How to suppress FFMPEG warning for BluRay files?

[jsakkos-curio]

When processing .mkv files from BluRay rips, I get the following warning repeatedly:

Could not find codec parameters for stream 3 (Subtitle: hdmv_pgs_subtitle (pgssub)): unspecified size
Consider increasing the value for the 'analyzeduration' (0) and 'probesize' (5000000) options

From what I can tell, this warning isn't cause for concern, I just want to suppress it, as I'm getting spammed. It happens both with the pyav and ffmpeg plugins.

The plugin ffmpeg is implemented based on imageio-ffmpeg.
You may transfer the issue to this repository.

Update:
@jsakkos-curio You may pass ffpmeg_params=['-loglevel', 'error'] towards imread to bypass the warning message of FFMPEG:

import imageio.v3 as iio
image = iio.imread('myvideo.mp4', plugin='FFMPEG', ffmpeg_params=['-loglevel', 'error'])
