hi Jeyasudha.M:
thank you for your help.
i am just focus on why the scale factor is so strange that the osdbox shape became too abnormal comparing to my desingnning.
i have another some questions need your answers if you are available.
Q1: the blimp can set the resolution of the osd, what is the usage of the resolution? just for the size of osd canvs? or somethig else?
Q2: how does the scale factor effect the finnal show out pictures? eg: i set the osd with 480p and my input video is 1080p, what should i do to adjust the scale factors?
thank you so much for your warm heart help.
Best Regards
Xutao
