Original commit message from CVS: * tests/.cvsignore: * tests/Makefile.am: * tests/mass_elements.c: (gst_get_current_time), (main): add simple benchmark to test various speeds of fakesrc ! identity ! identity ! ... ! fakesink. Usage: mass_elements [num_identities] [num_buffers] If not specified they default to 1000.
