Please describe the problem:
I have an encoding device that produces MP4 files. When i decode it using decodebin, the chosen demuxer is qtdemux. However:
* qtdemux complains
* there are minor side effects, such as duration-related ones (unable to determine)

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 playbin uri=file://$uri

Actual results:
The file is played back quite normally (should it ?)

Expected results:
No warning

Does this happen every time?
Yes
