Comment:
The original sample is in http://samples.ffmpeg.org/ffmpeg-
bugs/trac/ticket3923/, I attached a remuxed sample that shows identical
behaviour with FFmpeg, WMP and QT.
WMP indeed shows no visible artefacts for the file, QT shows approximately
the same artefacts as FFmpeg before 3af2de76
Current FFmpeg shows significantly stronger artefacts, they are also
visible with the attached I-frame but that did not look better with older
versions of FFmpeg.
