Hi, I have a problem reading from media folder (Or Umbraco has).

I have followed these instructions to move my media folder: https://our.umbraco.com/documentation/Extending/FileSystemProviders/

My composer:

public class SetMediaFileSystemComposer : IComposer
{
    public void Compose(IUmbracoBuilder builder)
    {
        builder.SetMediaFileSystem((factory) =>
        {
            var hostingEnvironment = factory.GetRequiredService<IHostingEnvironment>();
            var settings = factory.GetRequiredService<ISiteSettings>();
            var globalSettings = factory.GetRequiredService<IOptions<GlobalSettings>>().Value;
            var mediaFolder = settings.MediaPath.Fallback(globalSettings.UmbracoMediaPath);

            var rootPath = mediaFolder.StartsWith("~")
                ? hostingEnvironment.MapPathWebRoot(mediaFolder)
                : mediaFolder;

            var rootUrl = hostingEnvironment.ToAbsolute("/Media");

            return new PhysicalFileSystem(
                factory.GetRequiredService<IIOHelper>(),
                hostingEnvironment,
                factory.GetRequiredService<ILogger<PhysicalFileSystem>>(),
                rootPath,
                rootUrl);
        });
    }
}

My ISiteSettings is from my appsettings.json:

{
  "SiteSettings": {
    "MediaPath": "D:\\Code\\_RuntimeFiles\\Media"
  }
}  

When I upload a image in BackOffice, I can see that the image is created in D:\Code_RuntimeFiles\Media

But Umbraco can't display the image in BackOffice or in my views.

A bug?

When I added a custom ImageController to override the "get" part, I could display the image (BackOffice and in my views). But then ImageProccessor didn't started...

public class MediaController : Controller
{
    private readonly MediaFileManager _mediaFileManager;
    private readonly IImageUrlGenerator _imageUrlGenerator;

    public MediaController(
        MediaFileManager fileManager, 
        IImageUrlGenerator imageUrlGenerator)
    {
        _mediaFileManager = fileManager;
        _imageUrlGenerator = imageUrlGenerator;
    }

    public IActionResult Index(string id, string file)
    {
        var imagePath = Path.Combine(id, file);

        var ext = Path.GetExtension(imagePath);

        // we need to check if it is an image by extension
        if (_imageUrlGenerator.IsSupportedImageFormat(ext) == false)
            return NotFound();

        var image = _mediaFileManager.FileSystem.OpenFile(imagePath);
        return File(image, MediaTypeNames.Image.Jpeg);
    }
}
