+#!/usr/bin/env bash
+#
+# Behavior:
+#   Userscript for qutebrowser which views the current web page in mpv using
+#   sensible mpv-flags. While viewing the page in MPV, all <video>, <embed>,
+#   and <object> tags in the original page are temporarily removed. Clicking on
+#   such a removed video restores the respective video.
+#
+#   In order to use this script, just start it using `spawn --userscript` from
+#   qutebrowser. I recommend using an alias, e.g. put this in the
+#   [alias]-section of qutebrowser.conf:
+#
+#     mpv = spawn --userscript /path/to/view_in_mpv
+#
+# Background:
+#   Most of my machines are too slow to play youtube videos using html5, but
+#   they work fine in mpv (and mpv has further advantages like video scaling,
+#   etc). Of course, I don't want the video to be played (or even to be
+#   downloaded) twice — in MPV and in qwebkit. So I often close the tab after
+#   opening it in mpv. However, I actually want to keep the rest of the page
+#   (comments and video suggestions), i.e. only the videos should disappear
+#   when mpv is started. And that's precisely what the present script does.
+#
+# Thorsten Wißmann, 2015 (thorsten` on Libera Chat)
+# Any feedback is welcome!
