You could just call ff_filter_process_command() instead of hardcoding 
supported commands here. It will ignore any option without the 
AV_OPT_FLAG_RUNTIME_PARAM flag.

This is going to generate memleaks, and needlessly reallocate unrelated 
buffers.
You should instead av_realloc all four s->bboxes buffers here, and reset 
s->limit.

I don't have knowledge in c/c++, I based my changes on vf_crop.c, but i 
will look into your suggestions.
