------- Comment #1 from Edward Hervey  2008-12-03 10:15 UTC -------
for some reason qtdemux is outputing a newsegment with a rate of ... 0.000015

 creating newsegment update 0, rate 0.000015, format GST_FORMAT_TIME, start
0:00:00.000000000, stop 0:12:51.105000000, position 0:00:00.000000000

The value that seems wrong is the rate value parsed in qtdemux_parse_segments:

created segment 0 time 0:00:00.000000000, duration 0:12:51.105000000,
media_time 0:00:00.000000000, rate 1.52588e-05

The value is read as a "floating point 32bit", whereas reading it as a "32bit
unsigned integer" returns 1.

The QTFF specifications state the following regarding the "media rate field":
"""A 32-bit fixed-point number that specifies the relative rate at which to
play the media corresponding to this edit segment. This rate value cannot be 0
or negative."""
