 Summary of the bug:
 ffplay produces a whole lot of
 [mp3 @ 0x7f024000a7a0] Header missingB vq= 6678KB sq=    0B f=0/0   Last
 message repeated 47 times

 [mp3 @ 0x7f024000a7a0] Header missingB vq= 6717KB sq=    0B f=0/0   Last

 and audio is stuttering and frequently dropped / skipped.

 This worked fine with ffmpeg 2.7.3.
