MMAL graph

Wed Sep 12, 2018 12:29 pm

HI, what are those utility functions? are those used for create easy code with standard components? If yes is possible to attach a callback on the last componente of the graph that return the data (i.e.: contain_reader->decoder-> callback with buffer frame)?
Thanks

Pass.
I vaguely recall why they were written, but have never used them myself.

I'm not interested in doing contracts for bespoke functionality - please don't ask.
