The file has an edit-list that specifies to play from the 1.3s. offset, while it has only 1s. worth of samples.

Edit list:
Entry[0].SegmentDuration 4294967046
Entry[0].MediaTime 20800
Entry[0].MediaRateInteger 1
Entry[0].MediaRateFraction 0

While total duration in mdhd itself is 16000 only
mdhd:
Timescale 19200
Duration 16000

So, the edit list parsing code is doing the correct thing by not producing any frames. Please investigate why such an edit list has been introduced in the file.
