sheenachhabra 9581af110a Write "stco" box instead of "co64" for fragmented MP4 
As per MP4 spec ISO 14496-12: 8.7.5 Chunk Offset Box, Both "stco" and
"co64" can be used to store chunk offsets. While "stco" supports 32-bit
offsets, "co64" supports 64-bit offsets.
In non fragmented MP4, the mdat box can be extremely large, hence muxer
uses "co64" box.
But for fragmented MP4, muxer does not write any data in this chunk offset
box (present in "moov" box) because all sample related info is present in
"moof" box.
Technically, "co64" box should also work in fragmented MP4because
its empty only but QuickTime player fails to play video if "co64"
box is present in fragmented MP4 output file.

Testing: Verified that QuickTime player does not play video when "co64"
box is present but is able to play when "stco" box is present.
