omxvideo: start sharing more code between video decoder and encoder Identical functionality spread of two different components. We can't use a common base class because of different inheritance, but let's try to share the code anyway. https://bugzilla.gnome.org/show_bug.cgi?id=726024

gstomxvideodec: fix framerate overflow Some live streams can set the framerate to 50000/1677 (=29.81). GstVideoInfo.fps_n << 16 is wrong if the fps_n is 50000 (i.e. greater than 32767). https://bugzilla.gnome.org/show_bug.cgi?id=759043

omxvideodec: ignore very little variations of the framerate If less than 1%. The dynamic format change should not happen when the resolution does not change and when only the framerate changes but very slightly, i.e. from 50000/1677=29.81 to 89/3=29.66 so a "percentage change" of less than 1% (i.e. 100*(29.81-29.66)/29.66 = 0.50 < 1 ). In that case just ignore it to avoid unnecessary renegotiation. https://bugzilla.gnome.org/show_bug.cgi?id=759043
