I understand you want to shorten the working time for ‘from video device’ block.
The block sample rate is a parameter that can be used to control the rate at which the "From Video Device" block captures and outputs frames. The block sample rate is specified in frames per second (FPS).
To shorten the working time of the "From Video Device" block, you can increase the block sample rate. This will cause the block to capture and output frames more quickly.
It is important to note that shortening the working time of the "From Video Device" block may also reduce the quality of the video stream. So, experimentation needs to be done with different settings to find the best balance between performance and quality.
