Comment (by Ace17):

 > Is the issue reproducible with current FFmpeg git head?

 Yes.
 I just reproduced the issue with git commit
 d227ed5d598340e719eff7156b1aa0a4469e9a6a .

 > Is the issue reproducible with ffmpeg, the application?

 No, because the ffmpeg application fails muxing the corresponding HEVC
 elementary stream.

 The resulting output.ts is empty, but this is another issue.
