Please describe the problem:
All ffmpeg-based media players/frameworks complain every second (approx) when playing the following video back (see below).

The effects are mostly side effects. When h264 parse is inserted, warnings resolve but video plays back badly

Steps to reproduce:
1. wget https://flowty-public-dev.s3.amazonaws.com/2008-10-22_20-42-59.mp4
2. GST_DEBUG=2 gst-launch-0.10 -vvv filesrc location=emc.mp4 ! qtdemux ! ffdec_h264 ! xvimagesink


Actual results:
Errors, sometimes non-fluid playback (whenever a decoding error happens, tiny freeze)

Expected results:
Fluid playback and no decoding errors

Does this happen every time?
Yes
