How do I tell from source rpm's:

1. the build order of gstreamer packages
2. the command line args for the ./configure

For centos 7.

Look in the .spec file, specifically at the %prep, %build, and %install sections.

For more than you ever wanted to know, see http://ftp.rpm.org/max-rpm/ particularly chapter 13.

I replied from my phone yesterday, and it doesn't appear to have gone through...

The _chronological_ build order is most easily inferred from the RPM tag %{BUILDTIME}.  Usage example:

[lowen@dhcp-pool102 ~]$ rpm -qa --qf "%{BUILDTIME} -- %{NAME}\n" |grep gstreamer1|sort 1501713160 -- gstreamer1 1501713160 -- gstreamer1-devel 1502039500 -- gstreamer1-plugins-good 1523411572 -- gstreamer1-plugins-bad-free 1523411572 -- gstreamer1-plugins-bad-free-gtk 1523411627 -- gstreamer1-plugins-ugly-free 1540923990 -- gstreamer1-plugins-base 1540923990 -- gstreamer1-plugins-base-devel [lowen@dhcp-pool102 ~]$

It's pretty easy to see which packages were built at the same time, and the chronological order the others were built in.  To query this from a set of src.rpms just use 'rpm -qp ....' with the full package filename(s) instead of just the package name.  I used -qa and a grep feeding a sort to keep it 'simple,' although I have mixed repositories represented in that build order.  With a set of src.rpms you have better control of what you're checking in terms of the order of the build.
