I suggest you read the source of avfilter.
A filter can request a writeable RGB32 buffer if it wants. The filter core
will ensure that the filter gets exactly that then, if the previous filters
output is not compatble with that then the core will do whatever copy and
convertion is needed.
Ive no interrest in hacking around on vhook or reviewing patches working
around its limitations ...
