measure/perf does not support streams w/ floating point framerate #28

Closed dvrogozh closed 3 years ago

dvrogozh commented 3 years ago

measure-perf does not correctly handle streams w/ floating point framerates. For example, consider stream w/ framerate=29.97:

#####################################################################
PNP MEDIA SMT AVC-AVC: MULTISTREAM: 1 & ITERATION: 0
#####################################################################
 CONCURRENT: h264_HP@L4_0 123.58 fps/stream , Meets ContentFPS 28500.0 : False , Within margin 2%: 0 True

measure-perf won't go above 1st iteration and thinks that stream is of crazy framerate=28500.

Compare w/ stream of framerate=25:

#####################################################################
PNP MEDIA SMT AVC-AVC: MULTISTREAM: 1 & ITERATION: 0
#####################################################################
 CONCURRENT: 1920x1088_fld_0 25.02 fps/stream , Meets ContentFPS 23.75 : True , Within margin 2%: 0 True
