Original commit message from CVS: 2005-11-17 Andy Wingo <wingo@pobox.com> * check/Makefile.am (check_PROGRAMS): * check/net/gstnetclientclock.c: Add a most minimal test for the net client clock. More to come later. * gst/net/gstnet.h: * gst/net/Makefile.am: Add netclientclock. * gst/net/gstnetclientclock.h: * gst/net/gstnetclientclock.c: New files, implement an untested GstClock that takes its time from a network time provider. Implements the algorithm in network-clock.scm. * tests/network-clock.scm (*window-size*): Rename from *queue-length*. * tests/network-clock.scm (network-time): * tests/network-clock-utils.scm (q-push): Update callers.
