I set var of side_data for AVFrame with a value of “side_data”. I debugged the code and found that MPP didn't use this value when encoding. Is it MPP doesn't support setting side_data?

Not implemented yet. The last time I try it was still buggy. You can try it yourself and welcome to open a new PR.

Has this issue been resolved，if anyone have good solutions? The demo supports SEI insertion with mpp_meta_set_ptr(meta, KEY_USER_DATA, &user_data); Thandks
