There is NO option to edit fps in cheese. Cheese just streams direct video input from your webcam.
You mention slow fps during recording, but I'm assuming that the video displayed in cheese even when not recording has the same slow fps, right?
In effect, the fps you see before recording is what you are recording?
If so, I imagine you are recording in your room? which means low lighting.
- try taking the laptop outside in bright sunlight and test if the fps improves or not.
If fps does improve outside, it means that webcam driver is running with an auto-exposure setting ON.
(That means the fps depends directly on the webcam exposure. More light more fps. Less light less fps.)
Some webcam drivers might have an option to turn this setting off.
To check : Install the
v4l2ucp program. Once installed, you can start the program from the menu item
System > Preferences > Video4Linux Control Panel .
Check if you have the options for Automatic Gain and Exposure (a checkbox) , Exposure , Gain. If you have the options, then you can turn it off and adjust the options as suitable.
If you do not have the options, it means your webcam driver does not yet support the auto-exposure options.
If the webcam has options to toggle Auto-Exposure when you boot into Windows, then you're in luck. The option can be included in Linux kernel for your webcam.
Check if there is an existing bug requesting the feature: Search in Product: v4l-dvb
If not, File a bug in the kernel. Product: v4l-dvb , Select Component: webcam
