Pointgrey camera driver parameter limits cfg file

I am trying to set the frame rate on my Point Grey Chameleon 3. The dynamic reconfigure has a max value of 100. This is set in the PointGrey.cfg file. However, the camera itself is capable of higher frame rates.

I have installed the camera driver from apt:

sudo apt-get install ros-kinetic-pointgrey-camera-driver

Is there a way for me to modify the PointGrey.cfg file somewhere? I assume with my install method that it is all packaged up in a binary file and not changeable. Is there a way to override the default PointGrey.cfg file with a custom one? Can I point the Nodelet at a new .cfg file? Maybe in the launch file?

I have a custom launch file already where I set various parameters for the Nodelet. I generated this launch file by copying the camera.launch file from the github page and adding parameters ( https://github.com/ros-drivers/pointg... ). Is there a line I could add in here to tell the Nodelet to use a custom .cfg file?

I have tried installing from source so that I can modify the PointGrey.cfg file, but I have not had any luck getting that to work either.

I ended up figuring out how to install from source. I was trying to copy just the pointgrey_camera_driver subfolder, but you need to do the entire repository so that the dependencies are met.

After doing this, I was able to change the PointGrey.cfg file and get higher frame rates.

As to the solution you ended up with: dynamic reconfigure is infrastructure that gets generated at compile time. So creating a workspace, cloning the sources, updating the config and then rebuilding is (at the moment) the only way to change the bounds for a config item.

It says I need more "points" to accept or unaccept my own answer.
