@How to get analytic roi coordinate

I have wrote code to parse analytic config files. But I meet another problem.

I thought you rewrote analytic plugin, that’s why i suggest above.
lines and text from analytic plugin will fill to frame meta data NvDsDisplayMeta, so you can add probe on osd sink pad to iterate through each frame meta data, to modify the lines and text as you want.
