Comment (by Balling):

 First of all sample is here now: https://samples.ffmpeg.org/ffmpeg-
 bugs/trac/ticket7912/

 Second, mediainfo does not see CC in mkv.

 Third, I do not understand what what is the actual problem here. And VLC
 is not help, it looks good, but sees some kind of second stream their of
 cc?

 4th, where is 3hu.mp4?
