 In the ml archive I found an initial report on an early version of
 Baptiste's patch that caused exactly the same error message: https://www
 .mail-archive.com/ffmpeg-devel at ffmpeg.org/msg83824.html

 Maybe it is related to this patch but that is just a rather uneducated
 guess.

 ffmpeg version git-2019-04-30-5650668a1b remuxes it without problems.
