Insert sei function gst_h264_parser_insert_sei with rust bindings

Hey,
I’m having troublefinding the rust binding equivalent of gst_h264_parser_insert_sei and gst_h264_create_sei_memory functions foudn here GstH264Parser

I need to insert sei into the h264 file that i’m reading.

Would I need to create my own bindings to these?

Thankyou!
