This allows the\nimporting of buffers to be moved closer the path start/stop simplifying\nthe code. Also by adding a simple running tracker the error logic in\nPipelineHandlerRkISP1 can be simplified as stop() can always be called.\n\nThis also removes all external users of RkISP1Path::video_ so it can be\nmade private.\n\nSigned-off-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>\n---\n src/libcamera/pipeline/rkisp1/rkisp1.cpp | 53 ++------------------\n
