A small command-line tool to show the output capture rate (in FPS) of a Datapath VisionRGB capture card. Works with cards that implement the RGBEasy API.
vrgb-fps is a lightweight program that performs no processing of the incoming frames; thus the framerate it reports generally excludes client-side latency and so reflects the capability of the capture card to deliver data.
Once the capture card is receiving a signal, run vrgb-fps, and it will print into the console the number of frames per second that the capture card is sending out. Keep in mind that this framerate is for the video mode that the input signal is set to.
Launch vrgb-fps without command-line options to receive a list of the toggles available.
Once running, vrgb-fps can be safely terminated by pressing CTRL + C.
Take care not to run other frame-capturing software simultaneously with vrgb-fps, as the framerate then reported may be inaccurate.
A Windows script is provided for building vrgb-fps using MinGW.
To build vrgb-fps, you will need to have installed the RGBEasy SDK, which is provided with Datapath's drivers for supported capture cards (the SDK is an optional part of the driver installation but might not be selected by default).
