Framerate defaults to 7Hz or less

[jeff-o]

The default launch file causes the framerate of the camera to default to 7Hz or less. The solution is to add this param to the launch file:

<param name="frame_rate" type="double" value="30" />

This has been tested with the Bumblebee and FireflyMV cameras.

Is type="double" necessary? Can you create a PR against the bumblebee and camera example launch files, please?

[jeff-o]

Looks like "double" isn't necessary.

Manually specifying the frame rate does the trick, but it looks like the driver attempts to determine the frame rate by itself, or at least set a maximum (line 178 of PointGreyCamera.cpp). Therefore, there's a chance that it is just staying on the default 7.5Hz even though the Bumblebee is capable of more.

[mikepurvis]

Okay, please submit a PR to change it to a more reasonable default.

@jeff-o Did you want to change this for the next release?

[jeff-o]

No need for me to do it; the change is already included in the new launch file RG committed with his changes.

I don't see frame_rate in either camera.launch or bumblebee.launch. Please confirm that this is as you want it:

Huh, weird. Well anyway, I've created a pull request to add a frame_rate parameter to the two launch files.
