mp4 file repair - UPDATE 1

[William Salibrici]

Thank you Michael. 
Do you know the units for the reserved-moov-update-period property?
Would that be milliseconds or seconds?

Regards,

Bill

You need to change the default values, they are max 64 bit unsigned int by default.  Which means it will only update the moov table every 585 years.  Try changing them to other values.

The same is true for the qtmux. So they should be in operation. However, when I make a recording using these default values and unexpectedly interrupt the recording, the resultant recording file is unreadable for the standard windows media player. My development machine is windows 7. I just did a test using gstreamer version 1.12.3 with the gstreamer pre-built binaries for windows.
