From 6193fdea698ad4486140bc6a00a9547ab979c8f7 Mon Sep 17 00:00:00 2001 From: Ahmed Rafiq Date: Sat, 4 Dec 2021 19:50:48 +0600 Subject: Use MimeTypes package to determine MIME type This simplifies the code since we don't have to keep large mappings of extensions and MIME types. We still keep the ability to override the mappings for: - filling in entries not present in the package, for e.g. ".azw3" - picking preferred extensions, for e.g. MimeTypes provides ".conf" as a possible extionsion for "text/plain", and while that is correct, ".txt" would be preferrable - compatibility reasons --- MediaBrowser.Model/MediaBrowser.Model.csproj | 4 + MediaBrowser.Model/Net/MimeTypes.cs | 147 +++++++++------------------ 2 files changed, 53 insertions(+), 98 deletions(-) (limited to 'MediaBrowser.Model') diff --git a/MediaBrowser.Model/MediaBrowser.Model.csproj b/MediaBrowser.Model/MediaBrowser.Model.csproj index 70fef5d66..b1fbe864b 100644 --- a/MediaBrowser.Model/MediaBrowser.Model.csproj +++ b/MediaBrowser.Model/MediaBrowser.Model.csproj @@ -31,6 +31,10 @@ + + all + runtime;
