 Tride to upgrade to 0.29-fixes on my frontend and found that some of the
 previous HD recordings did not play any more.
 They did play well earlier with master from october.
 Also tried with master and the same thing.

 The log will show:

 And just keep repeating that error.

 I cut out 10 seconds of the start of this recording and will attach it to
 this ticket.

 To me it seems like there is a bug introduced in ffmpeg, but I am not
 sure.
