Hello our pointgrey camera should deliver 60 fps @ 1280 x 1024 this is indeed if i use the flycapture program but if i try a record with ros then it always limits the number of fps to 21 for a record ? Is there any bug or workaround or must be some settings changed ? It was also not possible to change the framerate with the tool rqt_reconfigure, the limit was just 21 fps for a single record. Maybe there are some bandwith problems or something like that with ros but it is possible to get nearly the max number of fps with flycapture, the system is ubuntu 16.04 with ros-kinetic.

Best regards

Camera's tend to drop frames if they are running preprocessing methods such as auto-exposure. You can check rosparams and rqt-dynamic_reconfigure if there exist such methods.
