pyTest: updated how to check output duration when testEProcessMethods

Clement Champetier · Clement Champetier · commit 55fb7e5785d2 · 2016-01-06T16:22:44.000+01:00
* Need to check if duration of all output streams are almost equals to
the expected value. But we cannot ensure to have the exact value for all
streams (it may not be possible depending on the fps/rate of input
streams).
* And the result vary depending on the ffmpeg version.
