This file plays upside down in gstreamer, while it plays fine in VLC, mplayer
and Windows Media Player. The file is generated by LabView.
(400MB, sorry that I don't have any smaller example):

Considering that the original commit was just to fix a warning, perhaps it
could be reverted or the check could be made more robust. Currently it is
checking only strh, while strf could give more detailed information. VLC seems
to rely mostly on information in strh:
