Comment (by ttcoder):

 Not working specifically on this ticket this week, but while testing new
 AAC/AC-3 support added in hrev48554 changeset (thanks Adrien!, AC-3 works
 great), I came up with the attached file, that reliably makes the system
 go into the weeds :

 It freezes Deskbar and MediaPlayer, /bin/top shows 100% CPU being shared
 between media_addon_server and MediaPlayer, and sometimes after a couple
 minutes the tight loop concludes with a crash in the resampler or by the
 "oops" assert; this is on both my laptop with an old 46168 and the desktop
 with hrev48562, so I guess other people will be able to reproduce this ?

 Maybe this is another data point to more easily debug the "oops" problem.

 I'm not ruling out the file itself being corrupt in some way though, since
 it was not generated by MediaConverter but by my own app; but that would
 then show a vulnerability if nothing else..
