+What a member is told when the media tools fail: that it failed.
+
+An exception's text from ffmpeg or ffprobe names the operator's paths, versions
+and the libraries the build has; the member who asked needs none of it, and the
+operator finds it in their log. Read from the source, because what matters is
+that no reply in these handlers carries an exception's text at all.
