 Summary of the bug: a movie that I converted using ffmpeg cannot be
 trimmed with Quicktime Player on Mac (macOS 10.13.5).  It gives me the
 error message "operation cannot be completed". Playing the movie in
 QuickTime Player works fine.

 How to reproduce:
 % ffmpeg -loglevel error -hide_banner -nostats -nostdin -i input -map 0
 -c:s copy -map_metadata 0 -map_metadata:s:v 0:s:v -dn -map_metadata:s:a
 0:s:a -c:a aac -b:a 128k -codec:v hevc -tag:v hvc1 -preset faster -crf 25
 -profile:v main -x265-params "me=umh:subme=5:ref=4:aq-mode=2:aq-
 strength=1.0:psy-rd=2.0:psy-rdoq=1.0:rd=6:log-level=1" -f mp4 output
 ffmpeg version: N-91200-g1616b1be5a-tessus
 built on macOS 10.13.5  , built with Apple LLVM version 9.1.0

 An example, where clipping using Quicktime Player fails, can be found

 Just load the video in Quicktime Player, trim it anywhere, then try to
 save it.
 If you check the system log file, you will find only one error message
 "assertion failed: 17F77: libxpc.dylib + 75093" , but that seems unrelated
 to the problem here, because it occurs with other videos, too, where
 clipping works fine.

 I have other videos that I converted exactly the same way where clipping
 with QuickTime Player works fine.
