Makes me wonder if the arg parsing for those shouldn't be handled by the CameraSession - but I don't know if that's practical, and this is fine.

I've thought about it, but then decided that a function named listControls() should list controls unconditionally. I've actually thought about moving arg parsing (or rather interpretation) out of CameraSession for other arguments, but that became quite impractical. > Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com> > > > Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> > > --- > > src/cam/camera_session.cpp | 45 +++++++++++++++++ > > src/cam/camera_session.h | 4 ++ > > src/cam/main.cpp | 101 ++++++++----------------------------- > > 3 files changed, 70 insertions(+), 80 deletions(-) > > > > diff --git a/src/cam/camera_session.cpp b/src/cam/camera_session.cpp > > index 10e66446ee67..ceb2c3ab3a92 100644 > > --- a/src/cam/camera_session.cpp > > +++ b/src/cam/camera_session.cpp > > @@ -11,6 +11,7 @@ > > #include <sstream> > > > > #include <libcamera/control_ids.h> > > +#include <libcamera/property_ids.h> > > > > #include "camera_session.h" > > #include "event_loop.h" > > @@ -89,6 +90,50 @@ CameraSession::~CameraSession() > > camera_->release();

The three CamApp functions listControls(), listProperties() and infoConfiguration() operate on a camera. They would thus be better placed in the CameraSession class. Move them there. As they now have no error to return anymore, make them void functions.
