VIDEO_VARIABLE_FPS
Description
Get or set the FPS (Frame Per Second) number (Frame Rate) configuration in the VIDEO_FPS is MODE2.
This URL will not take effect if the VIDEO_FPS is MODE1 or the V2_STREAMING_METHOD is not TCP Only.
This URL could ask the encoder to send the video stream with the specific FPS number by the remote host. To do that, the ID is needed to encoder to know whom requests the change of video FPS number. The stream socket ID is used then.
The supported variable FPS number depends on the sensor and encoder (platform) capabilities. Here is the summary of the FPS number with sensors and encoders. Note that supported variable FPS number listed blow doesn't mean you could set them successfully. You need to check the return code to see if the URL was set successfully.
