Benjamin Otte fcf39956d7 tests/: add simple benchmark to test various speeds of fakesrc ! identity ! identity ! ... ! fakesink.
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.
