Audio Switcher VS TagLib#

I'm looking for a library to control Windows audio mixer, similar to AudioSwitcher (manage devices, audio sessions, individual volumes), but it has to be compatible with Mono. Any suggestions?

I want to use taglib-sharp to retrieve extended information about video files.

I am trying to the metadata on jpg files. I am using taglibsharp following this article.

The library TagLib# can be got from here, which also has some sample usage. https://github.com/mono/taglib-sharp

It sounds like you're referring to the ID3 metadata. I found this library that appears to have had recent development activity (judging solely on the last commit date on github).

I am working on two different C# projects to help organize my large collection of photos and videos. I have figured out how to read metadata from images (like when the items were taken, etc.), but what I cannot figure out is how to write/modify metadata in image and video files. I experimented with the examples in the README of TagLib# to try modifying metadata, but it wouldn’t work. I would attempt to modify the metadata but it didn't seem to actually modify the file at all. What I would like to do is find a way to modify the date taken metadata of photos and videos in my projects. Is there a way to do this, and if so how? I would greatly appreciate any info or help on how to do this. Thank you!

I use taglib-sharp for that: https://github.com/mono/taglib-sharp

When a photo is imported into a library, Jellyfin reads the EXIF/XMP properties from the file and populates the corresponding Jellyfin properties (a.k.a. metadata). (Actually it uses a package named taglib-sharp to read the properties from the file.)

Another vote for Taglib-Sharp (NuGet Package). I started writing a module using it, but I got distracted. Here is a really good write up of how to use it

You probably need this and this with SearchOption.AllDirectories. Then use File.Move to rename each file.
