[FFmpeg-devel] Patch for Reproducing Issue 7827

[Peter Belkner]

This patch does not improve or fix something instead it is meant for 
easily reproducing issue 7827 (as requested, cf. 
https://trac.ffmpeg.org/ticket/7827). I've to admit that I don't know 
how to produce a patch by "git format-patch" instead it was made by "git 
diff > muxing.patch".
