+https://github.com/mpv-player/mpv/commit/e6e6b0dcc7e9b0dbf35154a179b3dc1fcfcaff43
+
+To apply the patch to mpv 0.28.0 release tarball, hunk #4 is removed. Hunk #4
+checks if 'mpd_url' is safe, but the support for 'mpd_url' is not available
+for the 0.28.0 release. So it should be safe to remove hunk #4.

+Subject: [PATCH] ytdl_hook: whitelist protocols from urls retrieved from
+ youtube-dl
+
+Not very clean since there's a lot of potential unsafe urls that youtube-dl
+can give us, depending on whether it's a single url, split tracks,
+playlists, segmented dash, etc.
