The change for rpi::ScalerCrops changes the behaviour of how crops are advertised - we now need a non-RAW output stream to be configured to return the available crop control. Signed-off-by: Naushir Patuck <[email protected]>
Add a HailoPostProcessingStage::ConvertInferenceCoordinates() helper that converts from the inference (low res) image co-ordinate space to the main image space, accounting for different scaler crops. Fixup the Yolo inference and pose estimation stages to use this new helper. Signed-off-by: Naushir Patuck <[email protected]>
Add a new command line argument "--lores-par" that when set, preserves the 1:1 aspect ratio of the low res stream. This is only possible on the PiSP platform. The default behaviour is to have this switch disabled, allowing for identical behaviour betwen VC4 and PiSP platforms. This requires the use of the rpi::ScalerCrops vendor control. This switch can also be triggered via the "rpicam-apps.lores.par" key in the postprocessing JSON file. Signed-off-by: Naushir Patuck <[email protected]>
