Hi,
I wanted to know details about the magic number check with upstream
size(upstream_size > 4*(1<<20)) is being used in qtdemux push mode under
mdat parsing prior upstream seeking.
Refer to below link for exact line of code:
https://github.com/GStreamer/gst-plugins-good/blob/1.12.4/gst/isomp4/qtdemux.c#L6464This change has been added as part below commit:

qtdemux: push mode; perform some extra checks prior to upstream seeking
It would helpful if, someone can provide info why this magic number check is
required and is there threshold limit for upstream seek to work?
