[FFmpeg-devel] [PATCH] avfilter/vf_cropdetect: add ability to change limit/reset at runtime

[Jeffrey CHAPUIS]

> 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.
