As far as I can tell, we can already queue a Buffer (albeit a new one) from the request completion handler, and the only thing that the pipeline handler does with the buffer is to store it in a newly allocated RkISP1FrameInfo that is stored in the frameInfo_ map in a new entry. I don't see what resource is now being reused that wasn't being reused before and that requires the RkISP1FrameInfo to be destroyed first. Feel free to keep the change, but please update the commit message (possibly to explain why I'm wrong :-)). > } > > void PipelineHandlerRkISP1::bufferReady(Buffer *buffer)

The FrameBuffer interface will allow reuse of FrameBuffers form the request completion handler. For this reason the pipeline must destroy its cached information freeing the statistics and parameters buffer used to allow them to be reused directly.
