Unable to download 'libfreeimage-3.16.0-osx10.6.dylib' using imageio.plugins.freeimage.download()

I am trying to read *.hdr image using imageio python library. I am using the free image plugin for imageio in order to do this.

imageio.plugins.freeimage.download()

However I get the following error even though I am connected to the internet.

Ascertaining binaries for: freeimage.

Development environment

MacOS 11.2.1

I even tried manually downloading the file from github but did not succeed
in reading the HDR files.

ffmpeg-win64-v4.2.2.exe printing a line of text when playing

Hello,
I have a question about the ffmpeg.exe file. I wrote a discord bot using discord.py, which plays audio when somebody joins a channel. I want that program to run in the background, so i use a .bat and a .vbs file so no command prompt appears when starting the script. Everytime the bot creates an audio source from mp3 files, it prints out a line "[mp3 @ 0000020168869040] Estimating duration from bitrate, this may be inaccurate". Therefore a console windows opens for 1sec to display this message and closes afterwards, which is really annoying. I use the ffmpeg-win64-v4.2.2.exe file with the discord.py lib to return an audio source, which can be played later "audio_source = discord.FFmpegPCMAudio(executable="E:/PythonPrograms/DiscordBotHallo/Dateien/ffmpeg-win64-v4.2.2.exe", source=source)". I actually dont know if this line of text comes from the ffmpeg .exe file or from the discord.py lib itself, but i got no answer on the discord server of the discord.py lib so i thought i ask my question where i downloaded the .exe file.
So if this message come from the .exe file. Is there a way to prevent this, so i can run my program in the background without any console window appearing?
Thanks

my code if needed:
main.txt

ValueError: Could not find a backend to open `50rgb.exr`` with iomode `wi`.

Guys I would like to save an 16 rgb bit array as .exr with imageio

		rgb_array = np.zeros((760, 1016, 3), dtype=np.uint16)
		rgb_array[:, :, 0] = array16[1::2, 1::2] # red
		# Must avoid overflowing 16-bits in the addition here:
		rgb_array[:, :, 1] = (array16[0::2, 1::2].astype(int) + array16[1::2, 0::2]) / 2 # green
		rgb_array[:, :, 2] = array16[0::2, 0::2] # blue

		imageio.imwrite(f'{exp}rgb.exr', rgb_array)

Build process for generating these binaries

It would be useful to have scripts included here to regenerate these binaries.

That would allow other people to see what is needed to build there own compatible libraries, and also allow auditing that these generated binaries are reproducible , ensuring they are accurate builds without any injected code.

Commit 3104b27 breaks ffmpeg download for older versions of imageio

Commit 3104b27 breaks ffmpeg download for older versions of imageio. For example 2.1.2. It used to download files named like "ffmpeg.linux64", and imageio.plugins.ffmpeg.download() now fails with 404 error

I recommend to revert this commit.

Missing arm64 libfreeimage dylib(for Mac OS X - M1, M2 Silicon)

On imageio/core/findlib.py, load_lib function, Occur Exception below.

---------- ERROR LOG -----------
One or more freeimage libraries were found, but could not be loaded due to the following errors:

------------------------------------

As you know, that dylib build by x86_64.
But, Apple silicon need arm64 binary library.

Exposure value in HDR-FI format is written incorrectly

Exposure value is a scalar multiplier. By default, writing to HDR images seems to result in files with exposure = 0

is imageio compatible with ffmpeg-3.3.2+ on windows ?
